PCCN® Exam (Progressive Care Certified Nurse) — Questions and Answers

Question 1: A patient with neutropenia (ANC < 500) develops a temperature of 38.5°C. The nurse should anticipate which intervention first?

Isolation and observation for 24 hours
Antifungal prophylaxis
Blood cultures and broad-spectrum antibiotics (Correct answer)
Oral antipyretics only

Correct answer: Blood cultures and broad-spectrum antibiotics

Febrile neutropenia is a medical emergency; blood cultures must be obtained and broad-spectrum antibiotics started promptly.

Question 2: Which breath sound is most commonly associated with fluid in the alveoli?

Rhonchi
Stridor
Wheezes
Fine crackles (Correct answer)

Correct answer: Fine crackles

Fine crackles, also known as rales, are short, high-pitched, popping sounds heard during inspiration. They are produced when collapsed alveoli or small airways suddenly open, often due to the presence of fluid. This makes them a characteristic finding in conditions like pulmonary edema or pneumonia where fluid accumulates in the alveoli.

Question 3: A patient with severe asthma is prescribed methylprednisolone. Which nursing action is most appropriate when administering this medication?

Encourage fluid restriction
Avoid giving with meals
Administer with grapefruit juice
Monitor blood glucose levels closely (Correct answer)

Correct answer: Monitor blood glucose levels closely

Methylprednisolone is a corticosteroid, and a common and significant side effect of corticosteroids is hyperglycemia (elevated blood glucose levels). Nurses must closely monitor blood glucose, especially in patients with diabetes or those at risk, to manage this potential complication effectively. This monitoring helps prevent adverse outcomes related to uncontrolled blood sugar.

Question 4: Which of the following is a key differentiating feature between Diabetic Ketoacidosis (DKA) and Hyperosmolar Hyperglycemic State (HHS)?

The presence of significant ketosis and metabolic acidosis (Correct answer)
The level of consciousness
The degree of hyperglycemia
The presence of severe dehydration

Correct answer: The presence of significant ketosis and metabolic acidosis

While both DKA and HHS involve hyperglycemia and dehydration, the hallmark of DKA is the presence of significant ketosis (leading to ketone bodies in the blood and urine) and a subsequent metabolic acidosis. In HHS, there is enough insulin to prevent ketosis, but not enough to prevent severe hyperglycemia.

Question 5: A patient recovering from septic shock develops bilateral pulmonary infiltrates, PaO2/FiO2 ratio of 150, and respiratory failure without cardiac cause. The nurse recognizes this as:

Hospital-acquired pneumonia
Acute respiratory distress syndrome (ARDS) (Correct answer)
Cardiogenic pulmonary edema
Pulmonary embolism

Correct answer: Acute respiratory distress syndrome (ARDS)

Bilateral infiltrates, severe hypoxemia (P/F < 200), and non-cardiac etiology following sepsis meet the Berlin criteria for ARDS.

Question 6: Confidentiality is best maintained in the progressive care setting by:

Sharing information only with friends or family
Discussing patient cases during breaks in the lounge
Speaking quietly during handoff at the nurses' station (Correct answer)
Using only initials on whiteboards

Correct answer: Speaking quietly during handoff at the nurses' station

Maintaining patient confidentiality is paramount in healthcare. Speaking quietly during handoff reports at the nurses' station minimizes the risk of unauthorized individuals overhearing sensitive patient information. Discussing cases in public areas, using only initials, or sharing information with friends/family are breaches of confidentiality and HIPAA violations.

Question 7: Which hemodynamic profile is characteristic of early distributive (septic) shock?

Low SVR, low CO, high PCWP
Low SVR, high CO, low PCWP (Correct answer)
High SVR, low CO, high PCWP
High SVR, high CO, normal PCWP

Correct answer: Low SVR, high CO, low PCWP

Septic shock causes vasodilation (low SVR), compensatory high cardiac output, and low filling pressures (low PCWP) in early stages.

Question 8: In a patient with chronic obstructive pulmonary disease (COPD), which symptom suggests the need for hospitalization?

Use of accessory muscles to breathe (Correct answer)
Cough with white sputum
Dyspnea on exertion
Barrel-shaped chest

Correct answer: Use of accessory muscles to breathe

The use of accessory muscles to breathe signifies increased work of breathing and severe respiratory distress, indicating a significant exacerbation of COPD. This symptom suggests that the patient's respiratory system is struggling to maintain adequate oxygenation and ventilation. It is a critical sign requiring immediate medical attention and likely hospitalization to prevent respiratory failure.

Question 9: A progressive care nurse is educating a patient being discharged after an asthma exacerbation. Which statement by the patient indicates a need for further teaching?

"I should use my rescue inhaler more often if my symptoms get worse."
"I need to use my inhaled corticosteroid every day, even when I feel fine."
"I will use my albuterol inhaler 15 minutes before I exercise."
"If I feel short of breath, I will take my oral prednisone immediately." (Correct answer)

Correct answer: "If I feel short of breath, I will take my oral prednisone immediately."

Oral corticosteroids like prednisone are not rescue medications for acute shortness of breath. They are used for managing more severe, prolonged exacerbations, typically as a prescribed tapering course. The patient should have a clear action plan that involves using their short-acting beta-agonist (rescue inhaler) for acute symptoms and seeking medical attention if symptoms do not improve. The other statements demonstrate correct understanding of asthma self-management.

Question 10: Which ECG change is commonly associated with hypokalemia?

U waves (Correct answer)
Peaked T waves
ST elevation
Prolonged QT interval

Correct answer: U waves

Hypokalemia, a low potassium level, commonly manifests on an ECG as the presence of U waves, which are small, positive deflections following the T wave. It can also cause flattened or inverted T waves and a prolonged QT interval. Peaked T waves, in contrast, are characteristic of hyperkalemia.

Question 11: Which intervention best addresses sleep deprivation in a progressive care patient?

Restricting family visitation during evening hours only
Encouraging napping throughout the day to make up for nighttime disruptions
Clustering care activities, minimizing nighttime interruptions, and reducing lighting and noise at night (Correct answer)
Administering nightly sedative-hypnotics routinely for all patients

Correct answer: Clustering care activities, minimizing nighttime interruptions, and reducing lighting and noise at night

Evidence-based sleep promotion bundles in the PCU include clustering care to reduce overnight interruptions, lowering light and noise levels at night, and minimizing unnecessary monitoring, which prevents delirium and promotes recovery.

Question 12: Which intervention is most appropriate for a patient with upper gastrointestinal bleeding and hematemesis?

Encouraging ambulation
Initiating a high-fiber diet
Administering proton pump inhibitor (Correct answer)
Providing oral fluids

Correct answer: Administering proton pump inhibitor

Upper gastrointestinal bleeding, especially with hematemesis, often results from conditions like peptic ulcers or erosions where stomach acid plays a significant role. Proton pump inhibitors (PPIs) reduce gastric acid secretion, which helps to stabilize the clot, prevent further bleeding, and promote healing of the gastric mucosa. This is a critical intervention to manage the underlying cause and prevent re-bleeding.

Question 13: Which condition is characterized by a sudden onset of sharp chest pain and dyspnea, often associated with a pneumothorax?

Pulmonary edema
Pleural effusion
Pneumothorax (Correct answer)
Pulmonary embolism

Correct answer: Pneumothorax

A pneumothorax is the presence of air in the pleural space, which causes the lung to collapse. This condition typically presents with a sudden onset of sharp, pleuritic chest pain (pain that worsens with breathing) and dyspnea (shortness of breath) as the lung's ability to expand is compromised. The other options have different primary presentations.

Question 14: A patient with liver cirrhosis is at risk for hepatic encephalopathy. Which assessment finding most supports this diagnosis?

Hypoactive bowel sounds
Asterixis (flapping hand tremor) (Correct answer)
Clay-colored stools
Right upper quadrant pain

Correct answer: Asterixis (flapping hand tremor)

Hepatic encephalopathy is a neurological complication of liver cirrhosis caused by the accumulation of toxins, primarily ammonia, in the bloodstream. Asterixis, often called a 'liver flap,' is a characteristic motor disturbance seen in patients with this condition. It indicates impaired neurological function due to the liver's inability to detoxify harmful substances.

Question 15: Which laboratory finding is most consistent with disseminated intravascular coagulation (DIC)?

Low fibrinogen and elevated D-dimer (Correct answer)
Elevated platelets and normal PT
Elevated fibrinogen and low D-dimer
Normal PTT and low INR

Correct answer: Low fibrinogen and elevated D-dimer

DIC is characterized by consumption of clotting factors and fibrinogen, along with elevated D-dimer from fibrinolysis.

Question 16: A nurse is caring for a patient with a chest tube. Which finding should be reported immediately?

Constant bubbling in the water seal chamber (Correct answer)
Intermittent tidaling in the water seal
Drainage of 50 mL serosanguinous fluid in 2 hours
Gentle bubbling in the suction chamber

Correct answer: Constant bubbling in the water seal chamber

Constant bubbling in the water seal chamber, especially if it's a new finding or persists after an initial air leak has resolved, indicates a persistent air leak in the chest tube system or from the patient's lung. This requires immediate investigation and intervention as it suggests ongoing air leakage from the pleural space or a problem with the tubing integrity. Gentle bubbling in the suction chamber is normal.

Question 17: A patient admitted for cardiac monitoring discloses feelings of hopelessness and that life is not worth living. What is the nurse's priority action?

Administer an as-needed anxiolytic medication
Reassure the patient that these feelings are normal after a cardiac event
Document the statement and notify the physician at the next scheduled rounding
Perform a structured suicidal ideation assessment and notify the care team immediately (Correct answer)

Correct answer: Perform a structured suicidal ideation assessment and notify the care team immediately

Statements indicating hopelessness and passive suicidal ideation require immediate structured risk assessment and prompt notification of the multidisciplinary team to ensure patient safety.

Question 18: Which of the following signs is most concerning for impending brain herniation in a patient with traumatic brain injury?

Dilated, non-reactive pupils (Correct answer)
Vomiting
Headache
Restlessness and agitation

Correct answer: Dilated, non-reactive pupils

Dilated, non-reactive pupils, especially if unilateral, are a critical sign of impending brain herniation. This indicates compression of the oculomotor nerve (CN III) due to severe increased intracranial pressure, which is a neurological emergency. While restlessness, headache, and vomiting are also symptoms of increased ICP, dilated non-reactive pupils signify a more advanced and life-threatening stage of brain compression.

Question 19: What principle of ethical practice is demonstrated by respecting a patient’s right to refuse treatment?

Nonmaleficence
Autonomy (Correct answer)
Fidelity
Justice

Correct answer: Autonomy

Autonomy is the ethical principle that respects an individual's right to make their own decisions about their healthcare, free from coercion. Allowing a patient to refuse treatment, even if it goes against medical advice, upholds their right to self-determination and their personal values. This principle is fundamental to patient-centered care.

Question 20: A patient with atrial fibrillation is started on warfarin. What is the primary lab value used to monitor its therapeutic effect?

Fibrinogen level
Platelet count
aPTT
INR (Correct answer)

Correct answer: INR

The International Normalized Ratio (INR) is the standard laboratory test used to monitor the therapeutic effect of warfarin. It measures the extrinsic pathway of coagulation and helps ensure the patient's blood is adequately thinned to prevent clots without increasing the risk of bleeding. Maintaining the INR within the therapeutic range is crucial for patient safety and efficacy.

Question 21: Which electrolyte imbalance is most associated with mental status changes and muscle cramps?

Hyperkalemia
Hypocalcemia
Hyponatremia (Correct answer)
Hypernatremia

Correct answer: Hyponatremia

Hyponatremia, a low serum sodium level, significantly affects neurological function because sodium is critical for nerve impulse transmission and maintaining fluid balance in brain cells. Symptoms often include mental status changes such as confusion, lethargy, and disorientation, as well as muscle cramps, weakness, and seizures in severe cases.

Question 22: When a nurse admits a terminally ill patient who requests no life-prolonging treatment, the nurse should:

Inform the patient they must be resuscitated in all situations
Provide life-sustaining treatments until the DNR is written
Respect the verbal request as legal and stop all interventions
Call the physician to clarify advance directives (Correct answer)

Correct answer: Call the physician to clarify advance directives

A verbal request for no life-prolonging treatment is important, but it must be legally documented as an advance directive (e.g., DNR/DNI) to be actionable. The nurse's role is to ensure the patient's wishes are formally recognized and ordered by the physician, protecting both the patient's autonomy and the healthcare team legally. Calling the physician clarifies the patient's wishes and initiates the proper documentation process.

Question 23: A nurse assigned to care for a former romantic partner should:

Ask a co-worker to do all treatments
Request reassignment to avoid potential conflict (Correct answer)
Inform the patient not to disclose their past relationship
Continue with care as assigned

Correct answer: Request reassignment to avoid potential conflict

To maintain professional boundaries, avoid potential conflicts of interest, and ensure objective care, a nurse should request reassignment if a patient is a former romantic partner. This protects both the patient's privacy and the nurse's professional integrity, preventing any emotional or personal biases from affecting care. Continuing care could compromise the therapeutic relationship.

Question 24: Which of the following best reflects proper technique when inserting an indwelling urinary catheter in a female patient?

Inflate the balloon before advancing the catheter
Use sterile gloves and sterile technique (Correct answer)
Use clean gloves and clean technique
Insert catheter 1 inch beyond urine flow return

Correct answer: Use sterile gloves and sterile technique

Inserting an indwelling urinary catheter is a sterile procedure that requires the use of sterile gloves and strict sterile technique. This is crucial to prevent the introduction of microorganisms into the urinary tract, thereby minimizing the risk of catheter-associated urinary tract infections (CAUTIs). Maintaining sterility throughout the procedure is paramount for patient safety.

Question 25: A patient with a history of adrenal insufficiency presents with hypotension, weakness, and hyperpigmentation. What is the likely diagnosis?

Addisonian crisis (Correct answer)
Cushing syndrome
Myxedema coma
Graves’ disease

Correct answer: Addisonian crisis

Addisonian crisis is a severe, life-threatening emergency caused by acute adrenal insufficiency. The classic symptoms of hypotension, weakness, and hyperpigmentation, especially in a patient with a history of adrenal insufficiency, are indicative of this condition. These manifestations result from critical deficiencies in cortisol and aldosterone, leading to circulatory collapse and electrolyte imbalances.

Question 26: A progressive care patient who has been hospitalized for 5 days becomes confused at night, attempts to pull out his IV, and reports seeing insects on the ceiling. Which condition does this presentation most likely indicate?

ICU/hospital-acquired delirium (Correct answer)
Psychotic depression
Hyponatremia
New-onset dementia

Correct answer: ICU/hospital-acquired delirium

Hospital-acquired delirium is characterized by acute onset of fluctuating confusion, disorientation, and perceptual disturbances, and is extremely common in progressive care patients.

Question 27: Which medication is typically administered to reverse the effects of opioid overdose?

Atropine
Naloxone (Correct answer)
Flumazenil
Protamine sulfate

Correct answer: Naloxone

Naloxone is an opioid antagonist specifically used to rapidly reverse the effects of opioid overdose by blocking opioid receptors. It is a life-saving medication that can quickly restore respiratory function in patients experiencing opioid-induced respiratory depression. Its rapid action makes it the drug of choice for opioid overdose emergencies.

Question 28: A patient with a history of heart failure is being discharged from the progressive care unit. The nurse is providing education on lifestyle modifications. Which statement by the patient indicates a need for further teaching?

"I will weigh myself every morning and call my doctor if I gain more than 3 pounds in a day."
"I need to make sure I take my medications every day, even if I am feeling better."
"I should limit my sodium intake to no more than 2,000 milligrams per day."
"I will try to drink at least 3 liters of water every day to stay hydrated." (Correct answer)

Correct answer: "I will try to drink at least 3 liters of water every day to stay hydrated."

Patients with heart failure are often on a fluid restriction to prevent volume overload. Encouraging a high fluid intake, such as 3 liters per day, would be contraindicated and indicates a need for further education. Daily weights, sodium restriction, and medication adherence are all key components of successful heart failure self-management.

Question 29: Which of the following Glasgow Coma Scale (GCS) scores indicates moderate brain injury?

9–12 (Correct answer)
13–15
3–8
6–9

Correct answer: 9–12

The Glasgow Coma Scale (GCS) is a standardized neurological assessment tool used to measure a person's level of consciousness. A GCS score of 9–12 indicates a moderate brain injury, reflecting a significant but not severe impairment. Scores of 13–15 are considered mild, while 3–8 signify a severe brain injury, requiring close monitoring and intervention.

Question 30: Which of the following is a common side effect of ACE inhibitors such as lisinopril?

Constipation
Bradycardia
Urinary retention
Dry cough (Correct answer)

Correct answer: Dry cough

A persistent, dry cough is a common and well-known side effect of ACE inhibitors like lisinopril. This cough is thought to be related to the accumulation of bradykinin, a substance that ACE inhibitors prevent from breaking down. While generally benign, it can be bothersome enough to warrant a change in medication.

Question 31: A patient receiving heparin begins to develop signs of heparin-induced thrombocytopenia (HIT). What is the most appropriate action?

Administer vitamin K
Increase the heparin dose
Administer platelet transfusion
Discontinue heparin and notify the provider (Correct answer)

Correct answer: Discontinue heparin and notify the provider

If a patient develops signs of heparin-induced thrombocytopenia (HIT), such as a significant drop in platelet count or new thrombosis, the most appropriate and immediate action is to discontinue all heparin products. Notifying the provider is crucial for initiating alternative anticoagulation and further management, as HIT is a serious, potentially life-threatening condition.

Question 32: A patient with chronic kidney disease reports nausea, fatigue, and a metallic taste. Which lab result supports uremia?

Creatinine 0.9 mg/dL
Sodium 140 mEq/L
Hematocrit 42%
BUN 80 mg/dL (Correct answer)

Correct answer: BUN 80 mg/dL

Uremia is a syndrome of symptoms and signs associated with severe kidney failure, resulting from the accumulation of nitrogenous waste products in the blood. A significantly elevated Blood Urea Nitrogen (BUN) level, such as 80 mg/dL (normal range typically 7-20 mg/dL), is a key indicator of impaired kidney function and the presence of uremia, correlating with symptoms like nausea, fatigue, and a metallic taste.

Question 33: A 68-year-old male with a history of heart failure is admitted with a diagnosis of community-acquired pneumonia. He presents with a productive cough, fever of 38.9°C, and crackles in the right lower lobe. Which of the following orders should the nurse prioritize?

Obtain blood and sputum cultures.
Administer intravenous antibiotics.
Administer PRN antipyretics.
Titrate oxygen to maintain SpO2 > 92%. (Correct answer)

Correct answer: Titrate oxygen to maintain SpO2 > 92%.

While all orders are important, ensuring adequate oxygenation is the immediate priority according to the ABCs (Airway, Breathing, Circulation). Hypoxia is a common and life-threatening complication of pneumonia. Once oxygenation is stabilized, the nurse should proceed with obtaining cultures before administering antibiotics to ensure the correct pathogen is identified.

Question 34: Which medication is used to reverse the anticoagulant effects of warfarin in case of major bleeding?

Idarucizumab
Protamine sulfate
Vitamin D
Vitamin K (Correct answer)

Correct answer: Vitamin K

Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Therefore, in cases of major bleeding or significant overdose, administering Vitamin K (phytonadione) can reverse its anticoagulant effects by promoting the synthesis of these clotting factors. Protamine sulfate reverses heparin, and idarucizumab reverses dabigatran.

Question 35: In assessing a patient with cholecystitis, which clinical sign is most commonly expected?

Left lower quadrant pain
Ascites
Murphy’s sign (pain with inspiration during palpation of RUQ) (Correct answer)
Hematochezia

Correct answer: Murphy’s sign (pain with inspiration during palpation of RUQ)

Cholecystitis is inflammation of the gallbladder, typically caused by gallstones obstructing the cystic duct. Murphy's sign is a classic clinical finding where a patient experiences sharp pain and inspiratory arrest when the examiner palpates the right upper quadrant (RUQ) beneath the liver edge during inspiration. This maneuver causes the inflamed gallbladder to descend and contact the examiner's hand, eliciting pain.

Question 36: A patient receiving a blood transfusion develops fever, chills, and flank pain 15 minutes after initiation. What is the nurse's first action?

Stop the transfusion immediately (Correct answer)
Obtain a repeat type and crossmatch
Administer acetaminophen
Slow the transfusion rate

Correct answer: Stop the transfusion immediately

Signs of a hemolytic transfusion reaction require immediate cessation of the transfusion to prevent life-threatening complications.

Question 37: A nurse notices that a colleague is documenting vital signs without actually taking them. What is the most appropriate first step?

Report the behavior to the nurse manager (Correct answer)
Confront the colleague in front of others
Ignore the situation
Document your own vital signs over theirs

Correct answer: Report the behavior to the nurse manager

Falsifying documentation is a serious breach of professional ethics and patient safety. The most appropriate first step is to report the behavior to the nurse manager, who has the authority and responsibility to address such misconduct. This ensures patient safety is maintained and professional standards are upheld, without directly confronting the colleague in a potentially unprofessional manner.

Question 38: A progressive care patient meets SIRS criteria and has a suspected infection. According to current definitions, this patient has:

SIRS without sepsis
Septic shock
Bacteremia
Sepsis (Correct answer)

Correct answer: Sepsis

Sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection; SIRS + infection meets the older sepsis definition and warrants treatment.

Question 39: Which finding in a patient with pneumonia requires immediate intervention?

Temperature of 101.2°F (38.4°C)
Respiratory rate of 24 breaths per minute
New-onset confusion and restlessness (Correct answer)
Productive cough with yellow sputum

Correct answer: New-onset confusion and restlessness

New-onset confusion and restlessness in a patient with pneumonia can indicate hypoxemia (low oxygen levels) or developing sepsis, especially in older adults. These are signs of worsening respiratory status or systemic compromise that require immediate assessment and intervention to prevent further deterioration. Other findings like cough and fever are expected with pneumonia but are less immediately concerning than acute neurological changes.

Question 40: The nurse is caring for a patient admitted with Diabetic Ketoacidosis (DKA). The initial potassium level was 5.8 mEq/L. After several hours of treatment with intravenous fluids and an insulin infusion, the patient's potassium level is now 3.2 mEq/L. What is the nurse's priority action?

Decrease the rate of the insulin infusion.
Administer intravenous potassium as ordered. (Correct answer)
Administer a dose of sodium polystyrene sulfonate (Kayexalate).
Continue to monitor the patient without intervention.

Correct answer: Administer intravenous potassium as ordered.

Insulin therapy in DKA drives potassium from the extracellular fluid into the cells, which can lead to a rapid drop in serum potassium levels and cause hypokalemia. A potassium level of 3.2 mEq/L is low and requires replacement to prevent cardiac dysrhythmias and other complications. Administering potassium is the priority.

Question 41: Which of the following pain scales is most appropriate for use with a nonverbal, intubated patient?

Behavioral Pain Scale (BPS) (Correct answer)
Wong-Baker FACES scale
Numeric Rating Scale (NRS)
Visual Analog Scale (VAS)

Correct answer: Behavioral Pain Scale (BPS)

The Behavioral Pain Scale (BPS) is specifically designed for assessing pain in critically ill, nonverbal, and intubated patients. It evaluates observable behaviors such as facial expression, upper limb movements, and compliance with ventilation, providing an objective measure of pain when self-report is not possible. Other scales require verbal or cognitive ability.

Question 42: A patient in septic shock has a MAP of 58 mmHg despite 2 liters of IV fluid. Which vasopressor is the first-line agent per Surviving Sepsis guidelines?

Phenylephrine
Norepinephrine (Correct answer)
Epinephrine
Vasopressin

Correct answer: Norepinephrine

Norepinephrine is the first-line vasopressor for septic shock per Surviving Sepsis Campaign guidelines due to its alpha-adrenergic effects.

Question 43: A patient has a central venous catheter. Which sign most suggests a catheter-related bloodstream infection?

Tachypnea and wheezing
Edema around the insertion site
Phlebitis and vein discoloration
Fever with no obvious source (Correct answer)

Correct answer: Fever with no obvious source

Fever with no obvious source is a hallmark sign of a catheter-related bloodstream infection (CRBSI). While local signs like redness or edema can occur, a systemic fever without another identifiable cause strongly suggests that the central line is the source of infection. Prompt investigation and management are crucial to prevent severe sepsis.

Question 44: Which intervention is most effective in preventing ventilator-associated pneumonia (VAP)?

Elevating the head of bed to 30–45 degrees (Correct answer)
Keeping the patient NPO
Administering broad-spectrum antibiotics
Suctioning every hour

Correct answer: Elevating the head of bed to 30–45 degrees

Elevating the head of the bed to 30-45 degrees (semi-recumbent position) is a cornerstone intervention for preventing ventilator-associated pneumonia (VAP). This position helps to reduce gastric reflux and the aspiration of oral and gastric secretions into the lungs, which are primary pathways for bacterial entry and subsequent pneumonia development in mechanically ventilated patients.

Question 45: A nurse is caring for a patient who was recently extubated after several days of mechanical ventilation. Which of the following parameters is the BEST indicator of the patient's readiness to be weaned from mechanical ventilation?

PaO2 of 85 mmHg on FiO2 of 40%
Tidal volume of 450 mL with a respiratory rate of 18 breaths/min
A rapid shallow breathing index (RSBI) of 95 (Correct answer)
Maximal inspiratory pressure (MIP) of -20 cm H2O

Correct answer: A rapid shallow breathing index (RSBI) of 95

The rapid shallow breathing index (RSBI), which is the ratio of respiratory frequency to tidal volume (f/VT), is a strong predictor of weaning success. An RSBI of less than 105 is a commonly accepted parameter indicating that a patient is likely to be successfully weaned. The other values, while important, are not as comprehensively predictive as the RSBI.

Question 46: The nurse is differentiating between delirium, dementia, and depression ('the 3 Ds') in a progressive care patient. Which feature is MOST characteristic of delirium compared to the other two?

Intact short-term memory with personality changes
Persistent low mood with anhedonia
Gradual onset over months to years
Acute onset with fluctuating level of consciousness (Correct answer)

Correct answer: Acute onset with fluctuating level of consciousness

Delirium is distinguished by its acute onset (hours to days), fluctuating course, and impaired consciousness, distinguishing it from the gradual progression of dementia and the mood-focused presentation of depression.

Question 47: Which clinical finding is most indicative of heparin-induced thrombocytopenia (HIT)?

Bleeding from IV sites within 24 hours
Platelet count of 400,000/mm³
Immediate platelet drop after first heparin dose
Platelet count drop of >50% after 5–14 days of heparin (Correct answer)

Correct answer: Platelet count drop of >50% after 5–14 days of heparin

HIT classically presents with a >50% decline in platelets occurring 5–14 days after heparin exposure due to antibody formation.

Question 48: A patient with anaphylactic shock after contrast dye administration. Which medication is administered first?

Epinephrine 1:1000 IM (Correct answer)
Ranitidine IV
Methylprednisolone IV
Diphenhydramine IV

Correct answer: Epinephrine 1:1000 IM

Epinephrine IM is the first-line and life-saving treatment for anaphylaxis, reversing bronchospasm and vasodilation immediately.

Question 49: Which assessment finding indicates the progressive care patient with systemic inflammatory response is developing organ hypoperfusion?

Heart rate of 96 bpm
WBC of 13,000/mm³
Temperature of 38.4°C
Urine output of 0.3 mL/kg/hr for 3 hours (Correct answer)

Correct answer: Urine output of 0.3 mL/kg/hr for 3 hours

Oliguria (< 0.5 mL/kg/hr) is an early indicator of renal hypoperfusion and impending organ dysfunction in sepsis.

Question 50: What is the primary concern when administering IV potassium chloride to a patient?

Arrhythmias (Correct answer)
Renal insufficiency
Hypotension
Nausea and vomiting

Correct answer: Arrhythmias

Administering IV potassium chloride too rapidly or in excessive amounts can lead to hyperkalemia, which significantly affects cardiac electrical activity. This can cause life-threatening arrhythmias, including bradycardia, heart block, and even cardiac arrest. Therefore, it must be administered slowly and carefully, often diluted, with close cardiac monitoring.

Question 51: A progressive care patient with a history of PTSD becomes extremely anxious when the nurse prepares to insert a urinary catheter. Which approach is MOST therapeutic?

Ask a colleague to perform the procedure so the primary nurse can comfort the patient from outside the room
Explain the procedure, obtain consent, allow the patient to set the pace, and offer distraction techniques (Correct answer)
Proceed quickly to minimize the duration of the stressor
Defer the procedure until the patient has received anxiolytic medication

Correct answer: Explain the procedure, obtain consent, allow the patient to set the pace, and offer distraction techniques

Trauma-informed care includes providing clear explanations, maintaining patient control and consent, proceeding at the patient's pace, and using distraction or relaxation techniques to reduce re-traumatization.

Question 52: When titrating a norepinephrine infusion for a patient in septic shock, the nurse's target MAP is:

65 mmHg (Correct answer)
55 mmHg
80 mmHg
50 mmHg

Correct answer: 65 mmHg

Surviving Sepsis guidelines recommend maintaining a MAP ≥ 65 mmHg as the initial resuscitation target for septic shock.

Question 53: Which laboratory result is most indicative of acute pancreatitis?

Low bilirubin
Decreased ALT and AST
Elevated alkaline phosphatase
Elevated amylase and lipase (Correct answer)

Correct answer: Elevated amylase and lipase

Acute pancreatitis involves inflammation of the pancreas, leading to the release of digestive enzymes into the bloodstream. Amylase and lipase are pancreatic enzymes, and their levels become significantly elevated in acute pancreatitis, often several times the normal range. Lipase is generally considered more specific for pancreatitis than amylase.

Question 54: A progressive care nurse is supporting the family of a patient who has just been told the prognosis is terminal. The family members are arguing among themselves and appear angry. The nurse should recognize this behavior as:

A dysfunctional family dynamic requiring immediate social work referral
A sign that family members require psychiatric evaluation
A normal grief response that may reflect denial, fear, and helplessness (Correct answer)
Evidence that the family has not been adequately informed of the diagnosis

Correct answer: A normal grief response that may reflect denial, fear, and helplessness

Anger and conflict among family members in crisis situations are common manifestations of grief and reflect normal emotional responses including helplessness, fear, and denial.

Question 55: A patient with acute respiratory distress syndrome (ARDS) is receiving mechanical ventilation with a low tidal volume strategy. What is the primary rationale for this intervention?

To reduce the risk of barotrauma and volutrauma. (Correct answer)
To prevent hypotension and cardiovascular collapse.
To decrease the patient's work of breathing and improve comfort.
To facilitate sedation and neuromuscular blockade.

Correct answer: To reduce the risk of barotrauma and volutrauma.

The primary goal of a low tidal volume ventilation strategy (typically 4-8 mL/kg of predicted body weight) in ARDS is to minimize ventilator-induced lung injury (VILI). High tidal volumes can overdistend and injure the less-affected alveoli, leading to volutrauma and barotrauma. Keeping plateau pressures below 30 cm H2O is a key component of this protective strategy.

Question 56: Which of the following medications is classified as a beta-1 selective blocker and commonly used in heart failure management?

Propranolol
Labetalol
Metoprolol (Correct answer)
Carvedilol

Correct answer: Metoprolol

Metoprolol is a beta-1 selective blocker, meaning it primarily blocks beta-1 adrenergic receptors in the heart, reducing heart rate and myocardial contractility. This action helps to decrease myocardial oxygen demand and is beneficial in managing heart failure. Propranolol, carvedilol, and labetalol are non-selective or have additional alpha-blocking properties.

Question 57: Which finding indicates a patient with sickle cell crisis is developing acute chest syndrome?

New infiltrate on chest X-ray with hypoxia (Correct answer)
Hemoglobin of 10 g/dL
WBC of 12,000/mm³
Pain localized to the lower back

Correct answer: New infiltrate on chest X-ray with hypoxia

Acute chest syndrome is diagnosed by a new pulmonary infiltrate on imaging combined with respiratory symptoms such as hypoxia.

Question 58: The nurse notices that a patient who was previously cooperative has become withdrawn, stopped eating, and states 'nothing matters anymore.' These findings are MOST consistent with:

Normal adjustment to hospitalization
Physiologic response to pain medication
Clinical depression requiring further assessment and intervention (Correct answer)
Delirium with hypoactive features

Correct answer: Clinical depression requiring further assessment and intervention

Withdrawal, anhedonia (loss of interest), anorexia, and hopelessness are hallmark symptoms of clinical depression that require formal assessment using validated tools (e.g., PHQ-2/PHQ-9) and prompt intervention.

Question 59: What is the primary action of nitroglycerin when used in acute coronary syndrome (ACS)?

Promotes platelet aggregation
Increases myocardial oxygen demand
Decreases heart rate
Dilates coronary arteries (Correct answer)

Correct answer: Dilates coronary arteries

Nitroglycerin primarily acts as a vasodilator, relaxing smooth muscle in both veins and arteries, including the coronary arteries. In acute coronary syndrome, this dilation increases blood flow to the ischemic myocardium, improving oxygen supply. It also reduces preload by venous dilation, which decreases myocardial oxygen demand.

Question 60: Which medication is most appropriate for treating increased intracranial pressure (ICP)?

Lorazepam
Mannitol (Correct answer)
Amiodarone
Morphine sulfate

Correct answer: Mannitol

Mannitol is an osmotic diuretic commonly used to treat increased intracranial pressure (ICP). It works by drawing fluid from the brain tissue into the vascular space, thereby reducing cerebral edema and ICP. This medication is crucial in neurocritical care to prevent secondary brain injury by maintaining adequate cerebral perfusion pressure. Other options like morphine or lorazepam are not primary treatments for ICP.

Question 61: Which parameter is most reliable in evaluating the effectiveness of oxygen therapy?

SpO₂ level (Correct answer)
Capillary refill
Lung sounds
Respiratory rate

Correct answer: SpO₂ level

The SpO₂ (pulse oximetry) level directly measures the percentage of hemoglobin saturated with oxygen in the arterial blood. It provides an immediate and objective assessment of oxygenation status and the effectiveness of oxygen therapy. While other parameters like respiratory rate and lung sounds are important, SpO₂ offers a direct physiological measure of how well the body is being oxygenated.

Question 62: A 68-year-old male with a history of type 2 diabetes is admitted to the progressive care unit with altered mental status. His laboratory results show a blood glucose of 850 mg/dL, serum osmolality of 340 mOsm/kg, and a negative urine ketone test. Which of the following interventions is the highest priority?

Obtaining a STAT head CT scan.
Administering an intravenous insulin bolus.
Initiating fluid resuscitation with an isotonic solution. (Correct answer)
Placing the patient on a cardiac monitor.

Correct answer: Initiating fluid resuscitation with an isotonic solution.

The patient's presentation is consistent with Hyperosmolar Hyperglycemic State (HHS). The most critical initial intervention is aggressive fluid resuscitation to correct the profound dehydration and hyperosmolality, which are the primary causes of the altered mental status. While insulin will be administered, correcting the fluid deficit is the first priority to restore tissue perfusion.

Question 63: A progressive care nurse is caring for a patient who is 48 hours post-coronary artery bypass graft (CABG) surgery. The patient is hemodynamically stable and has been extubated. Which nursing intervention is crucial to prevent postoperative pulmonary complications?

Limiting oral fluid intake to prevent fluid overload.
Administering cough suppressants to minimize incisional pain.
Encouraging the use of an incentive spirometer and splinting the incision when coughing. (Correct answer)
Maintaining strict bed rest for 72 hours.

Correct answer: Encouraging the use of an incentive spirometer and splinting the incision when coughing.

Postoperative pulmonary complications, such as atelectasis and pneumonia, are significant risks after CABG surgery. Encouraging deep breathing and coughing is essential to keep the lungs clear. Using an incentive spirometer helps with deep breathing, and splinting the chest incision with a pillow provides support and reduces pain during coughing, making it more effective. Strict bed rest, cough suppression, and fluid restriction would increase the risk of pulmonary complications.

Question 64: Which adverse effect should the nurse monitor for when a patient is receiving furosemide?

Hypertension
Hypokalemia (Correct answer)
Hypernatremia
Bradycardia

Correct answer: Hypokalemia

Furosemide is a loop diuretic that works by inhibiting sodium and chloride reabsorption in the loop of Henle, leading to increased excretion of water, sodium, potassium, and chloride. Therefore, hypokalemia (low potassium) is a common and significant adverse effect that nurses must monitor for. Potassium supplementation may be required to prevent cardiac arrhythmias.

Question 65: A nurse assesses a tracheostomy patient and notes a sudden drop in oxygen saturation and the sound of air escaping. What should the nurse suspect?

Tracheal stenosis
Mucus plug
Cuff leak or tracheostomy dislodgement (Correct answer)
Bronchospasm

Correct answer: Cuff leak or tracheostomy dislodgement

A sudden drop in oxygen saturation combined with the sound of air escaping around a tracheostomy tube strongly suggests a problem with the cuff or the tube's position. A cuff leak means air is escaping past the cuff instead of going into the lungs, reducing ventilation. Dislodgement means the tube is no longer correctly positioned in the trachea, leading to ineffective ventilation and air leakage, both requiring immediate intervention.

Question 66: A patient with aplastic anemia is in protective isolation. Which visitor instruction is most important?

Bring fresh flowers to improve patient mood
Wear an N95 respirator when entering the room
Avoid visiting if experiencing any illness or infection (Correct answer)
Limit visits to 30 minutes

Correct answer: Avoid visiting if experiencing any illness or infection

Visitors with any illness can transmit infection to an immunocompromised patient with aplastic anemia; exclusion of sick visitors is essential.

Question 67: What is the primary reason to place a patient in high Fowler’s position during a respiratory distress episode?

Reduce blood pressure
Improve venous return
Facilitate diaphragmatic expansion (Correct answer)
Prevent aspiration

Correct answer: Facilitate diaphragmatic expansion

Placing a patient in high Fowler's position (sitting upright at 60-90 degrees) allows gravity to pull the abdominal organs away from the diaphragm. This reduces pressure on the diaphragm, enabling it to move more freely and expand the lungs more effectively. This position optimizes lung expansion and improves ventilation, thereby easing respiratory distress.

Question 68: A patient on heparin infusion has a PTT of 210 seconds (goal 60–100 seconds). What is the priority nursing action?

Obtain a platelet count only
Administer vitamin K
Hold the infusion and notify the provider (Correct answer)
Increase the heparin rate

Correct answer: Hold the infusion and notify the provider

A supratherapeutic PTT significantly above goal indicates over-anticoagulation; the infusion should be stopped and the provider notified immediately.

Question 69: Which of the following medication classes is considered first-line for rate control in a stable patient newly diagnosed with atrial fibrillation and a rapid ventricular response?

Digoxin
Sodium channel blockers
Amiodarone
Beta-blockers (Correct answer)

Correct answer: Beta-blockers

For stable patients with atrial fibrillation and a rapid ventricular response, beta-blockers (e.g., metoprolol) or non-dihydropyridine calcium channel blockers (e.g., diltiazem) are recommended as first-line agents for rate control. Amiodarone is typically used for rhythm control or in specific situations like heart failure. Digoxin is generally considered a second-line agent as it is less effective at controlling heart rate during exercise. Sodium channel blockers are used for rhythm control, not rate control.

Question 70: Which drug is commonly used for sedation in mechanically ventilated patients and has both anxiolytic and amnestic effects?

Dexmedetomidine
Lorazepam
Propofol
Midazolam (Correct answer)

Correct answer: Midazolam

Midazolam is a short-acting benzodiazepine commonly used for sedation in mechanically ventilated patients due to its rapid onset and relatively short duration of action. It provides both anxiolytic (anxiety-reducing) and amnestic (memory-impairing) effects, which are beneficial for patient comfort and tolerance of mechanical ventilation. Other options have different primary uses or side effect profiles.

Question 71: Which laboratory result requires immediate reporting in a patient suspected of having thrombotic thrombocytopenic purpura (TTP)?

BUN of 22 mg/dL
Platelet count of 150,000/mm³
Hemoglobin of 11 g/dL
Peripheral smear showing schistocytes (Correct answer)

Correct answer: Peripheral smear showing schistocytes

Schistocytes (fragmented RBCs) on peripheral smear indicate microangiopathic hemolytic anemia, a hallmark finding of TTP.

Question 72: What is the primary goal of thrombolytic therapy in patients with acute myocardial infarction (MI)?

Decrease heart rate
Dissolve the existing blood clot (Correct answer)
Prevent platelet aggregation
Reduce myocardial oxygen demand

Correct answer: Dissolve the existing blood clot

The primary goal of thrombolytic therapy in acute myocardial infarction (MI) is to dissolve the blood clot (thrombus) that is obstructing blood flow in the coronary artery. By restoring blood flow (reperfusion) to the ischemic myocardial tissue, thrombolytics aim to limit infarct size, preserve cardiac function, and improve patient outcomes.

Question 73: A patient is admitted with acute decompensated heart failure. Which medication class is most appropriate to reduce preload and relieve pulmonary congestion?

ACE inhibitors
Calcium channel blockers
Beta blockers
Loop diuretics (Correct answer)

Correct answer: Loop diuretics

Loop diuretics, such as furosemide, are highly effective in acute decompensated heart failure because they promote rapid diuresis. By inhibiting sodium and chloride reabsorption in the loop of Henle, they reduce circulating blood volume. This action directly decreases preload and alleviates pulmonary congestion, which are key goals in managing acute heart failure.

Question 74: Which of the following medications requires a peak and trough level for safe administration?

Azithromycin
Ciprofloxacin
Vancomycin (Correct answer)
Acetaminophen

Correct answer: Vancomycin

Vancomycin is an antibiotic with a narrow therapeutic index, meaning the difference between an effective and a toxic dose is small. Therefore, peak and trough levels are routinely monitored to ensure therapeutic concentrations are achieved while minimizing the risk of serious adverse effects such as nephrotoxicity (kidney damage) and ototoxicity (hearing damage).

Question 75: Which medication is commonly used to reduce afterload in heart failure?

Furosemide
Digoxin
Metoprolol
Lisinopril (Correct answer)

Correct answer: Lisinopril

Lisinopril, an ACE inhibitor, reduces afterload by causing vasodilation, which decreases systemic vascular resistance. By lowering the resistance against which the heart must pump, it improves cardiac output and reduces the workload on the failing heart in patients with heart failure. This makes it a cornerstone medication for managing heart failure symptoms.

Question 76: Which action by the nurse demonstrates advocacy for a critically ill patient?

Communicating the patient’s wishes to the care team (Correct answer)
Avoiding conflict with the healthcare provider
Reassuring the patient’s family that everything is fine
Administering medications on time

Correct answer: Communicating the patient’s wishes to the care team

Patient advocacy involves speaking up for the patient, ensuring their rights are respected, and their needs and wishes are communicated effectively to the healthcare team. This empowers the patient, especially when they are critically ill and may not be able to advocate for themselves. Administering medications or reassuring family are important but do not solely define advocacy.

Question 77: A patient is brought to the unit with suspected adrenal crisis (Addisonian crisis). Which of the following assessment findings would be most consistent with this diagnosis?

Hypertension, hyperglycemia, and hypernatremia
Bradycardia, fluid overload, and hypokalemia
Tachycardia, hypertension, and hypercalcemia
Hypotension, hypoglycemia, and hyperkalemia (Correct answer)

Correct answer: Hypotension, hypoglycemia, and hyperkalemia

Adrenal crisis is a life-threatening condition caused by an acute deficiency of cortisol. The classic presentation includes severe hypotension (due to loss of vascular tone and volume), hypoglycemia (due to decreased gluconeogenesis), and hyperkalemia (due to aldosterone deficiency).

Question 78: Which nursing intervention helps prevent complications of portal hypertension in a patient with cirrhosis?

Encouraging high-protein intake
Administering lactulose (Correct answer)
Limiting fluid intake
Restricting physical activity

Correct answer: Administering lactulose

Portal hypertension in cirrhosis can lead to hepatic encephalopathy due to the accumulation of ammonia and other toxins. Lactulose works by trapping ammonia in the gut and promoting its excretion through the stool, thereby reducing systemic ammonia levels. This intervention directly addresses a major complication of portal hypertension by preventing or treating hepatic encephalopathy.

Question 79: Which intervention is a core component of sepsis bundle completion within 3 hours of identification?

Perform a lumbar puncture
Insert a central venous catheter
Initiate vasopressors immediately
Obtain blood cultures before antibiotics (Correct answer)

Correct answer: Obtain blood cultures before antibiotics

Obtaining blood cultures before antibiotic administration is a mandatory component of the Surviving Sepsis 1-hour bundle.

Question 80: A nurse is preparing to suction a patient’s endotracheal tube. What is the most appropriate action before suctioning?

Increase suction pressure to maximum
Hyperoxygenate the patient (Correct answer)
Instill normal saline into the airway
Turn off the ventilator

Correct answer: Hyperoxygenate the patient

Hyperoxygenating the patient before suctioning is a crucial step to prevent hypoxemia, which can occur during the procedure due to the removal of oxygen from the airway. This action helps to maintain adequate oxygen saturation and minimize the risk of complications such as arrhythmias or cardiac arrest. It ensures the patient has a reserve of oxygen during the temporary interruption of ventilation.

Question 81: Which finding best differentiates cardiogenic shock from hypovolemic shock?

Tachycardia
Hypotension
Cool, clammy skin
Elevated PCWP and reduced cardiac output (Correct answer)

Correct answer: Elevated PCWP and reduced cardiac output

Cardiogenic shock is characterized by elevated PCWP (fluid backing up) and reduced cardiac output, unlike hypovolemic shock which has low PCWP.

Question 82: Which intervention is MOST effective in preventing delirium in a progressive care patient?

Promoting sleep hygiene, early mobility, and reorientation strategies (Correct answer)
Administering prophylactic haloperidol nightly
Keeping the room darkened and quiet at all times
Providing continuous physical restraints to prevent falls

Correct answer: Promoting sleep hygiene, early mobility, and reorientation strategies

Non-pharmacologic bundles including sleep promotion, early mobilization, cognitive stimulation, and reorientation (e.g., ABCDEF bundle) are the most evidence-based approach to delirium prevention.

Question 83: A progressive care patient becomes acutely agitated, is pulling at lines, and poses a safety risk. Before applying physical restraints, the nurse should FIRST:

Attempt less restrictive alternatives such as re-orientation, removing triggers, and involving family (Correct answer)
Document the behavior and consult psychiatry before taking any action
Administer IV haloperidol without waiting for a physician order in an emergency
Obtain a physician's order and apply four-point restraints immediately

Correct answer: Attempt less restrictive alternatives such as re-orientation, removing triggers, and involving family

The least-restrictive approach must be attempted before restraints; non-pharmacologic de-escalation techniques including reorientation, removing offending stimuli, and family presence should be tried first.

Question 84: Which action is appropriate when administering IV potassium chloride?

Mix with dextrose 5% in water (D5W) only
Give with loop diuretics simultaneously
Use a central line for concentrations above 10 mEq/hr (Correct answer)
Administer via IV push for rapid replacement

Correct answer: Use a central line for concentrations above 10 mEq/hr

Intravenous potassium chloride is a high-alert medication that can cause severe irritation and damage to peripheral veins, especially at higher concentrations or rapid infusion rates. Therefore, concentrations exceeding 10 mEq/hr are typically administered via a central venous catheter. This allows for greater dilution and minimizes the risk of phlebitis, pain, and tissue damage.

Question 85: Post-intensive care syndrome (PICS) includes which combination of long-term sequelae that progressive care nurses should educate patients and families about?

Chronic pain, insomnia, and weight gain only
Hypertension, diabetes, and renal failure
Cognitive impairment, psychological disturbances (PTSD/depression/anxiety), and physical weakness (Correct answer)
Cardiac arrhythmias, neuropathy, and visual changes

Correct answer: Cognitive impairment, psychological disturbances (PTSD/depression/anxiety), and physical weakness

PICS encompasses a constellation of new or worsening impairments in cognitive function, mental health (PTSD, depression, anxiety), and physical/functional status that persist after critical illness.

Question 86: A patient in the progressive care unit develops sudden hypotension, tachycardia, and jugular venous distension after a central line insertion. The nurse suspects:

Tension pneumothorax (Correct answer)
Pulmonary embolism
Cardiac tamponade
Air embolism

Correct answer: Tension pneumothorax

Tension pneumothorax is a known complication of central line insertion presenting with hemodynamic instability and JVD from mediastinal shift.

Question 87: Which action best reflects the ethical principle of justice in nursing?

Providing equal care and resources to all patients (Correct answer)
Spending more time with the most agreeable patient
Prioritizing care based on who arrives first
Choosing to help the family of a VIP patient first

Correct answer: Providing equal care and resources to all patients

The ethical principle of justice in nursing dictates that all patients should receive fair and equitable care, regardless of their background, socioeconomic status, or personal characteristics. This means distributing resources and care impartially and without discrimination. Prioritizing based on personal preference or arrival time does not align with justice.

Question 88: Which of the following best describes the mechanism of action of ACE inhibitors?

Inhibits beta-adrenergic receptors
Blocks calcium channels in myocardial cells
Promotes reabsorption of sodium in renal tubules
Inhibits conversion of angiotensin I to angiotensin II (Correct answer)

Correct answer: Inhibits conversion of angiotensin I to angiotensin II

ACE inhibitors (Angiotensin-Converting Enzyme inhibitors) block the enzyme responsible for converting angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor and stimulates aldosterone release, so inhibiting its formation leads to vasodilation, reduced blood pressure, and decreased fluid retention. This mechanism makes them effective in treating hypertension and heart failure.

Question 89: What is the priority nursing action after inserting a nasogastric (NG) tube for feeding?

Start the feeding immediately
Clamp the tube and reassess in 30 minutes
Confirm placement with an abdominal X-ray (Correct answer)
Ask the patient if they can feel the tube in their throat

Correct answer: Confirm placement with an abdominal X-ray

Confirming nasogastric (NG) tube placement with an abdominal X-ray is the most reliable and gold standard method to ensure the tube is correctly positioned in the stomach or small intestine. This critical step prevents serious complications such as aspiration pneumonia if the tube were inadvertently placed in the lungs. Never initiate feeding until placement is radiographically confirmed.

Question 90: Which blood product is most appropriate for a patient with hemophilia A experiencing an acute bleed?

Fresh frozen plasma
Packed red blood cells
Platelets
Cryoprecipitate or Factor VIII concentrate (Correct answer)

Correct answer: Cryoprecipitate or Factor VIII concentrate

Hemophilia A is caused by Factor VIII deficiency; cryoprecipitate or recombinant Factor VIII concentrate replaces the missing factor.

Question 91: Which assessment tool is specifically validated for measuring delirium in acute care settings?

Mini-Mental State Examination (MMSE)
Montreal Cognitive Assessment (MoCA)
Glasgow Coma Scale (GCS)
Confusion Assessment Method (CAM) (Correct answer)

Correct answer: Confusion Assessment Method (CAM)

The Confusion Assessment Method (CAM) is the gold-standard validated tool for delirium assessment in acute/progressive care; the CAM-ICU is adapted for non-verbal/intubated patients.

Question 92: A family member of a dying patient asks the nurse, 'Is my mother suffering?' The patient is unconscious and receiving palliative sedation. Which response best reflects palliative care principles?

"It's hard to say — she may still be aware of pain at some level."
"She is not suffering; the medications are keeping her comfortable and peaceful." (Correct answer)
"We cannot know for certain what she is experiencing."
"You should speak with the physician about your concerns."

Correct answer: "She is not suffering; the medications are keeping her comfortable and peaceful."

Palliative sedation is titrated to ensure comfort; reassuring the family that the patient is comfortable is accurate, compassionate, and consistent with palliative care goals.

Question 93: Which action is most important when administering leukocyte-reduced blood products?

Administer slowly over 6 hours
Ensure the product is used to prevent CMV transmission (Correct answer)
Warm the blood to 40°C before infusion
Use a standard blood filter (170–260 microns)

Correct answer: Ensure the product is used to prevent CMV transmission

Leukocyte reduction reduces the risk of CMV transmission and febrile non-hemolytic reactions in at-risk patients.

Question 94: A patient with a history of COPD presents with confusion and somnolence. ABG results show pH 7.28, PaCO₂ 60 mmHg. What is the best initial nursing action?

Encourage deep breathing and coughing
Apply a non-rebreather mask
Prepare for intubation
Notify the provider and consider BiPAP (Correct answer)

Correct answer: Notify the provider and consider BiPAP

The ABG results (pH 7.28, PaCO₂ 60 mmHg) indicate severe respiratory acidosis with hypoventilation, consistent with COPD exacerbation and CO₂ retention, leading to confusion and somnolence. BiPAP (Bilevel Positive Airway Pressure) is a non-invasive ventilation method that can help improve ventilation, reduce PaCO₂, and prevent the need for intubation. Notifying the provider is crucial for medical orders and further management.

Question 95: What is the most important early goal in managing hemorrhagic shock following trauma?

Insert a pulmonary artery catheter
Administer high-dose corticosteroids
Control the source of bleeding (Correct answer)
Achieve a MAP > 90 mmHg with crystalloid

Correct answer: Control the source of bleeding

Definitive hemorrhage control is the primary goal because ongoing blood loss cannot be corrected by fluid resuscitation alone.

Question 96: A patient receiving morphine sulfate IV begins to experience respiratory depression. What is the most appropriate immediate intervention?

Administer naloxone (Correct answer)
Reposition the patient and observe
Place in Trendelenburg position
Increase IV fluid rate

Correct answer: Administer naloxone

Morphine sulfate is an opioid analgesic, and respiratory depression is a serious adverse effect. Naloxone is an opioid antagonist that rapidly reverses the effects of opioids by competing for receptor sites. Administering naloxone is the immediate and most appropriate intervention to counteract life-threatening respiratory depression.

Question 97: Which of the following rhythms requires immediate defibrillation?

Ventricular fibrillation (Correct answer)
Sinus tachycardia
Atrial flutter
Second-degree AV block type II

Correct answer: Ventricular fibrillation

Ventricular fibrillation (VFib) is a chaotic, life-threatening arrhythmia characterized by disorganized electrical activity in the ventricles, leading to ineffective cardiac contraction and immediate loss of consciousness. Immediate defibrillation is crucial to terminate VFib and restore a perfusing rhythm, as it is a pulseless rhythm requiring immediate electrical intervention.

Question 98: A patient is admitted with a diagnosis of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). The nurse would expect which of the following laboratory findings?

Hyponatremia and increased serum osmolality
Hyponatremia and decreased serum osmolality (Correct answer)
Hypernatremia and decreased serum osmolality
Hypernatremia and increased serum osmolality

Correct answer: Hyponatremia and decreased serum osmolality

In SIADH, there is an excessive release of antidiuretic hormone (ADH), leading to water retention by the kidneys. This results in a dilutional hyponatremia (low serum sodium) and a decreased serum osmolality because the excess water dilutes the blood solutes.

Question 99: A patient in the progressive care unit is being treated for a severe exacerbation of chronic obstructive pulmonary disease (COPD). Which of the following assessment findings would indicate the most urgent need for intervention?

Use of accessory muscles and a respiratory rate of 28 breaths/min
Reports of increased sputum production and cough
Decreased level of consciousness and confusion (Correct answer)
Oxygen saturation of 91% on 2L nasal cannula

Correct answer: Decreased level of consciousness and confusion

A decreased level of consciousness and confusion are signs of hypercapnia and severe respiratory distress, indicating impending respiratory failure. This is a life-threatening situation that requires immediate intervention, possibly including non-invasive or invasive mechanical ventilation. While the other options are concerning, they do not represent the same level of immediate threat as a change in mental status.

Question 100: A patient in obstructive shock due to a massive pulmonary embolism is hemodynamically unstable. The nurse anticipates which intervention?

Oral anticoagulation initiation
Immediate surgical embolectomy
Systemic thrombolysis with alteplase (Correct answer)
Intravenous heparin and observation

Correct answer: Systemic thrombolysis with alteplase

Massive PE with hemodynamic instability is an indication for systemic thrombolytic therapy to rapidly dissolve the clot and restore perfusion.

Question 101: Which finding would be most concerning in a patient with suspected bowel perforation?

Abdominal cramping
Nausea
Rigid, board-like abdomen (Correct answer)
Hyperactive bowel sounds

Correct answer: Rigid, board-like abdomen

A rigid, board-like abdomen is a classic sign of peritonitis, which is severe inflammation of the peritoneum, often caused by the leakage of gastrointestinal contents into the abdominal cavity due to bowel perforation. This finding indicates a medical emergency requiring immediate surgical intervention. Other symptoms like nausea and cramping are common but less specific for perforation.

Question 102: A nurse is caring for a patient experiencing opioid withdrawal. Which cluster of symptoms should the nurse expect?

Bradypnea, hypothermia, constipation, and euphoria
Tachycardia, diaphoresis, piloerection, and yawning (Correct answer)
Bradycardia, hypotension, miosis, and sedation
Hypertension, fever, hallucinations, and seizures

Correct answer: Tachycardia, diaphoresis, piloerection, and yawning

Opioid withdrawal produces a hyperadrenergic state characterized by tachycardia, diaphoresis, piloerection (goosebumps), yawning, lacrimation, and muscle aches.

Question 103: A patient with a spinal cord injury at the level of T4 is at risk for which potentially life-threatening complication?

Seizures
Cerebral aneurysm
Autonomic dysreflexia (Correct answer)
Brain herniation

Correct answer: Autonomic dysreflexia

Autonomic dysreflexia is a potentially life-threatening condition that can occur in patients with spinal cord injuries at or above T6. It is characterized by an exaggerated sympathetic response to noxious stimuli below the level of injury, leading to severe hypertension, bradycardia, and headache. A T4 injury places the patient at high risk for this emergency, requiring immediate recognition and management.

Question 104: A progressive care patient has a platelet count of 18,000/mm³. Which intervention is the highest priority?

Encourage ambulation
Initiate bleeding precautions (Correct answer)
Apply compression stockings
Administer aspirin for pain

Correct answer: Initiate bleeding precautions

A platelet count below 20,000/mm³ carries a high risk of spontaneous bleeding, requiring immediate bleeding precautions.

Question 105: A patient in the progressive care unit develops an acute kidney injury (AKI) following a severe hypotensive episode. Their urine output is 20 mL/hr, BUN is 45 mg/dL, and creatinine is 2.8 mg/dL. Which classification of AKI is most likely?

Chronic
Postrenal
Prerenal (Correct answer)
Intrarenal

Correct answer: Prerenal

Prerenal AKI is caused by decreased blood flow to the kidneys. A severe hypotensive episode leads to renal hypoperfusion. This is characterized by a high BUN to creatinine ratio (in this case >20:1 is suggested but not explicitly calculated without a baseline) and oliguria, as the kidneys attempt to conserve volume.

Question 106: A diabetic patient presents with fruity-smelling breath, confusion, and rapid, deep respirations. Which condition should the nurse suspect?

Diabetic ketoacidosis (DKA) (Correct answer)
Hypoglycemia
Metabolic alkalosis
Hyperosmolar hyperglycemic syndrome (HHS)

Correct answer: Diabetic ketoacidosis (DKA)

Diabetic ketoacidosis (DKA) is a severe complication of diabetes characterized by hyperglycemia, metabolic acidosis, and the presence of ketones. The classic signs include fruity-smelling breath (due to acetone), confusion (due to acidosis and dehydration), and Kussmaul respirations (rapid, deep breathing) as the body attempts to compensate for the acidosis.

Question 107: When preparing to transfuse irradiated blood products, the nurse understands this measure prevents which complication?

Febrile non-hemolytic reaction
Allergic urticarial reaction
Transfusion-associated graft-versus-host disease (Correct answer)
Hyperkalemia

Correct answer: Transfusion-associated graft-versus-host disease

Irradiation inactivates donor T lymphocytes, preventing transfusion-associated graft-versus-host disease in immunocompromised patients.

Question 108: Which parameter best reflects the adequacy of oxygen delivery during resuscitation from shock?

Blood pressure normalization
Heart rate below 100 bpm
Urine output > 30 mL/hr alone
Central venous oxygen saturation (ScvO2) > 70% (Correct answer)

Correct answer: Central venous oxygen saturation (ScvO2) > 70%

ScvO2 > 70% indicates that tissues are receiving adequate oxygen relative to demand, reflecting successful resuscitation at the cellular level.

Question 109: A nurse forgets to document a dose of medication but gave it. What is the appropriate action?

Ignore it to avoid getting in trouble
Alter the MAR to show it was given earlier
Create a new entry with the current time
Chart a late entry with the correct time and explanation (Correct answer)

Correct answer: Chart a late entry with the correct time and explanation

If a medication was given but not documented, the nurse must make a late entry in the patient's chart. This entry should accurately reflect the time the medication was administered and include an concise explanation for the delay in documentation. This ensures the medical record is accurate and complete, reflecting the actual care provided and maintaining legal integrity.

Question 110: Which of the following is a key nursing intervention for a patient admitted with a suspected pulmonary embolism (PE)?

Administering anticoagulation therapy as ordered.
Placing the patient in a high Fowler's position. (Correct answer)
Encouraging frequent ambulation to improve circulation.
Initiating a fluid bolus to improve cardiac output.

Correct answer: Placing the patient in a high Fowler's position.

Placing the patient in a high Fowler's position helps to maximize chest expansion and alleviate dyspnea, which is a common and distressing symptom of a pulmonary embolism. While anticoagulation is the cornerstone of treatment, immediate positioning to improve breathing is a critical initial nursing action. Ambulation is contraindicated as it could dislodge more clots. Fluid boluses should be given with caution as they can worsen right ventricular strain.

Question 111: A patient with a known seizure disorder experiences a tonic-clonic seizure lasting 8 minutes. What is the priority nursing action?

Administer IV lorazepam (Correct answer)
Record the seizure activity in the chart
Apply soft wrist restraints
Prepare for lumbar puncture

Correct answer: Administer IV lorazepam

A tonic-clonic seizure lasting 8 minutes is considered status epilepticus, a medical emergency requiring immediate intervention to prevent brain damage. IV lorazepam is a benzodiazepine that is the first-line treatment to abort prolonged seizures by enhancing GABAergic inhibition in the brain. Administering it promptly is the priority to stop the seizure activity.

Question 112: Which sign is most associated with increased intracranial pressure (ICP)?

Tachycardia
Widening pulse pressure and bradycardia (Correct answer)
Hypotension
Diaphoresis

Correct answer: Widening pulse pressure and bradycardia

Widening pulse pressure and bradycardia are two key components of Cushing's triad, which is a classic physiological response to increased intracranial pressure (ICP). Cushing's triad also includes irregular respirations. These signs indicate the body's attempt to maintain cerebral perfusion in the face of rising ICP, making them critical indicators of neurological deterioration.

Question 113: What is the most serious complication associated with esophageal varices?

Acid reflux
Strangulated hernia
Massive upper GI bleeding (Correct answer)
Aspiration pneumonia

Correct answer: Massive upper GI bleeding

Esophageal varices are dilated blood vessels in the esophagus that develop due to portal hypertension in liver disease. These vessels are fragile and prone to rupture, leading to life-threatening, massive upper gastrointestinal bleeding. This complication is a medical emergency with a high mortality rate, making it the most serious concern.

Question 114: The nurse is assessing a patient for alcohol withdrawal using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scale. Which finding would indicate the most severe level of withdrawal?

Moderate tremor and nausea with a score of 15
Severe agitation, hallucinations, and seizures with a score of 22 (Correct answer)
Mild diaphoresis and anxiety with a score of 8
Tachycardia and hypertension only with a score of 10

Correct answer: Severe agitation, hallucinations, and seizures with a score of 22

A CIWA-Ar score ≥20 indicates severe withdrawal requiring aggressive pharmacologic intervention; scores with seizures and hallucinations represent the highest risk category.

Question 115: A patient with acute coronary syndrome is found to have comorbid major depression. The nurse understands that depression in cardiac patients is significant because it:

Is associated with increased mortality, poor medication adherence, and worse cardiac outcomes (Correct answer)
Is a normal adjustment reaction that typically resolves without intervention within 6 months
Primarily affects quality of life but has no impact on physiologic cardiac function
Decreases pain perception and therefore reduces analgesic requirements

Correct answer: Is associated with increased mortality, poor medication adherence, and worse cardiac outcomes

Depression is an independent risk factor for adverse cardiac outcomes; it is associated with increased mortality, poor adherence to cardiac medications and lifestyle changes, and higher rates of recurrent cardiac events.

Question 116: A patient is prescribed a fentanyl patch for chronic pain. Which of the following instructions is most important?

Apply only to the upper chest
Avoid exposing the patch to heat (Correct answer)
Change the patch every 12 hours
Apply over broken skin for better absorption

Correct answer: Avoid exposing the patch to heat

Fentanyl patches release medication systemically, and heat (from heating pads, hot baths, or fever) can significantly increase the rate of fentanyl absorption. This accelerated absorption can lead to dangerously high serum fentanyl levels, increasing the risk of severe respiratory depression and overdose. Patients must be educated to avoid heat exposure to the patch.

Question 117: A patient receiving IV heparin has an aPTT that is significantly above the therapeutic range. What is the appropriate reversal agent?

Fresh frozen plasma
Desmopressin
Vitamin K
Protamine sulfate (Correct answer)

Correct answer: Protamine sulfate

Protamine sulfate is the specific antidote for heparin overdose. It works by forming a stable complex with heparin, neutralizing its anticoagulant effects. When a patient's aPTT is significantly elevated above the therapeutic range, indicating excessive anticoagulation, protamine sulfate is administered to reverse the effects and reduce bleeding risk.

Question 118: Which intervention is contraindicated in a patient with severe thrombocytopenia (platelets < 20,000/mm³)?

Stool softeners
IV saline lock for access
Rectal temperature measurement (Correct answer)
Soft toothbrush for oral hygiene

Correct answer: Rectal temperature measurement

Rectal procedures are contraindicated in severe thrombocytopenia due to the risk of rectal trauma and uncontrolled hemorrhage.

Question 119: A patient is prescribed filgrastim (G-CSF) following chemotherapy. The nurse understands this medication works by:

Stimulating platelet production
Stimulating neutrophil production (Correct answer)
Replacing clotting factors
Suppressing the immune response

Correct answer: Stimulating neutrophil production

Filgrastim (G-CSF) stimulates the bone marrow to produce neutrophils, reducing the duration and severity of neutropenia after chemotherapy.

Question 120: A patient presents with slurred speech, facial droop, and right-sided weakness. Which diagnostic test should be prioritized first?

Electroencephalogram (EEG)
Magnetic Resonance Imaging (MRI)
Computed Tomography (CT) scan of the head (Correct answer)
Carotid Doppler ultrasound

Correct answer: Computed Tomography (CT) scan of the head

A patient presenting with acute neurological deficits like slurred speech, facial droop, and weakness suggests a possible stroke. A CT scan of the head is prioritized to rapidly differentiate between ischemic and hemorrhagic stroke, as this distinction dictates immediate treatment. This quick assessment is critical for timely intervention, such as administering thrombolytics for ischemic stroke, and improving patient outcomes.

Question 121: A patient is admitted with acute decompensated heart failure (ADHF) and presents with dyspnea, orthopnea, and 3+ pitting edema in the lower extremities. The patient's blood pressure is 98/60 mmHg. Which of the following interventions is the priority for this patient?

Applying multi-layer compression wraps to the lower extremities.
Administering a bolus of intravenous normal saline.
Initiating an intravenous dobutamine infusion.
Administering intravenous furosemide. (Correct answer)

Correct answer: Administering intravenous furosemide.

The primary goal in treating acute decompensated heart failure with fluid overload is to reduce volume and relieve congestion. Intravenous loop diuretics, such as furosemide, are the first-line therapy to achieve this by promoting diuresis. Administering a fluid bolus would worsen the fluid overload. Compression wraps are contraindicated in hemodynamically unstable patients as they can shift fluid centrally and increase pulmonary congestion. While dobutamine (an inotrope) may be used if there is evidence of hypoperfusion, the initial priority is to address the severe fluid overload causing the patient's symptoms.

Question 122: A patient with crush injury from a building collapse develops tea-colored urine and rising creatinine. The nurse recognizes these findings as indicative of:

Rhabdomyolysis with acute kidney injury (Correct answer)
Contrast-induced nephropathy
Hepatic failure
Urinary tract infection

Correct answer: Rhabdomyolysis with acute kidney injury

Myoglobinuria from muscle breakdown causes tea-colored urine and tubular nephrotoxicity, leading to acute kidney injury in rhabdomyolysis.

Question 123: A patient with immune thrombocytopenic purpura (ITP) has a platelet count of 10,000/mm³. Which finding would require the most urgent intervention?

Mild bruising on the arms
Sudden severe headache and altered mental status (Correct answer)
Petechiae on the lower extremities
Prolonged bleeding after venipuncture

Correct answer: Sudden severe headache and altered mental status

Sudden severe headache and altered mental status suggest intracranial hemorrhage, the most dangerous complication of severe thrombocytopenia.

Question 124: Which ethical principle involves doing no harm to the patient?

Veracity
Autonomy
Nonmaleficence (Correct answer)
Justice

Correct answer: Nonmaleficence

Nonmaleficence is the ethical principle that means "do no harm." In nursing, this involves avoiding actions that could intentionally or unintentionally cause harm to a patient. It is a fundamental principle guiding all healthcare interventions and decisions, ensuring patient safety is prioritized.

Question 125: In monitoring a patient with a myocardial infarction, which cardiac marker rises first?

Myoglobin (Correct answer)
BNP
Troponin I
CK-MB

Correct answer: Myoglobin

Myoglobin is one of the earliest cardiac markers to rise following myocardial injury, typically within 1-4 hours after symptom onset. While it is sensitive for muscle damage, it is not specific to cardiac muscle. Troponin I and CK-MB rise later but are more specific for myocardial damage.
