Physiological Integrity — Questions and Answers
Question 1: What is the primary purpose of monitoring vital signs?
- To assess the effectiveness of medication
- To identify potential complications early (Correct answer)
- To ensure patient comfort during care
- To track fluid intake and output
Correct answer: To identify potential complications early
Monitoring vital signs (temperature, pulse, respiration, blood pressure, and oxygen saturation) provides crucial baseline data and indicates changes in a patient's physiological status. Significant deviations from normal ranges can signal the onset of acute complications or a worsening condition. This allows nurses to intervene promptly, preventing further deterioration and ensuring patient safety.
Question 2: Which of the following is a sign of hypovolemic shock?
- Increased blood pressure
- Weak, thready pulse and low blood pressure (Correct answer)
- Fever and rapid pulse
- Normal heart rate and blood pressure
Correct answer: Weak, thready pulse and low blood pressure
Hypovolemic shock results from a significant loss of blood or fluid volume, leading to inadequate tissue perfusion throughout the body. The body attempts to compensate by increasing heart rate, but the pulse becomes weak and thready due to decreased circulating volume. Blood pressure drops as the heart struggles to pump sufficient blood, indicating a critical and life-threatening state.
Question 3: What is the correct nursing intervention for a patient with acute pain?
- Ignoring the pain as it will resolve on its own
- Assessing the pain level and administering analgesics as prescribed (Correct answer)
- Encouraging the patient to sleep through the pain
- Requesting a family member to provide comfort
Correct answer: Assessing the pain level and administering analgesics as prescribed
Acute pain requires prompt and effective management to promote comfort and facilitate recovery. The nurse's role involves thoroughly assessing the patient's pain level using a standardized scale and then administering prescribed analgesics in a timely manner. This ensures the patient receives appropriate relief, prevents unnecessary suffering, and supports healing.
Question 4: Which of the following is a common complication of immobility?
- Improved circulation and muscle tone
- Increased risk for pressure ulcers (Correct answer)
- Strengthened respiratory function
- Decreased blood clot formation
Correct answer: Increased risk for pressure ulcers
Immobility significantly increases the risk for pressure ulcers (bedsores) because sustained pressure on bony prominences compromises blood flow to the skin and underlying tissues. Without regular repositioning and meticulous skin care, tissue ischemia and breakdown can occur. Other complications include muscle atrophy, contractures, and respiratory issues.
Question 5: How should the nurse assess a patient's respiratory rate?
- By asking the patient to breathe deeply and counting the number of breaths
- By palpating the carotid pulse while the patient is at rest
- By visually observing the rise and fall of the chest (Correct answer)
- By counting the number of seconds between breaths
Correct answer: By visually observing the rise and fall of the chest
To accurately assess a patient's respiratory rate, the nurse should visually observe the rise and fall of the chest or abdomen for a full minute. It is best to do this discreetly, without the patient's awareness, as they may unconsciously alter their breathing pattern if they know they are being observed. This method provides an objective and accurate measure of respiratory effort.
Question 6: Which of the following is a common sign of dehydration in an elderly patient?
- Increased urinary output
- Dry skin, confusion, and low blood pressure (Correct answer)
- Increased appetite and thirst
- Warm skin and high blood pressure
Correct answer: Dry skin, confusion, and low blood pressure
Elderly patients are particularly vulnerable to dehydration, and their symptoms can be subtle or atypical. Common signs include dry mucous membranes and skin, confusion or altered mental status, and low blood pressure (orthostatic hypotension). These symptoms reflect decreased circulating fluid volume and impaired cellular function, requiring prompt intervention.
Question 7: What is the most appropriate response to a patient experiencing a seizure?
- Restraining the patient to prevent movement
- Placing a tongue depressor in the patient's mouth
- Protecting the patient from injury and ensuring airway clearance (Correct answer)
- Administering sedatives immediately
Correct answer: Protecting the patient from injury and ensuring airway clearance
During a seizure, the primary nursing interventions focus on ensuring patient safety. This involves protecting the patient from injury by moving objects away and padding the head, while also ensuring their airway remains open by turning them on their side if possible. Restraining the patient or placing objects in their mouth can cause harm and should be avoided.
Question 8: Which of the following is an indication of a worsening infection?
- Decreased white blood cell count
- Fever, chills, and increased heart rate (Correct answer)
- Clear nasal discharge and slight cough
- Normal temperature and steady pulse
Correct answer: Fever, chills, and increased heart rate
A worsening infection is typically indicated by systemic inflammatory responses as the body fights the pathogen. Fever and chills are common signs, and an increased heart rate (tachycardia) often accompanies fever as the body tries to compensate for increased metabolic demands. These symptoms suggest the infection is progressing or becoming more severe, requiring prompt medical attention.
Question 9: What is the nurse's role in assisting a patient with post-operative pain management?
- Encouraging the patient to tolerate the pain without medication
- Assessing pain level and administering pain relief as prescribed (Correct answer)
- Withholding medication to prevent addiction
- Reassuring the patient that they do not need pain medication
Correct answer: Assessing pain level and administering pain relief as prescribed
The nurse's crucial role in post-operative pain management involves regularly assessing the patient's pain using an appropriate scale and then administering prescribed analgesics in a timely and effective manner. This ensures adequate pain control, which is vital for patient comfort, early mobilization, and preventing complications. Withholding medication or encouraging tolerance is inappropriate and unethical.
