Mixed Deck — All Paramedics Exam Topics Flashcards

What respiratory rate cutoff determines whether a patient is considered critical?

Answer: 30

A respiratory rate cutoff of 30 breaths per minute is often used as a critical threshold in patient assessment. A rate above this indicates significant respiratory distress or compromise, suggesting the patient is working very hard to breathe and may be experiencing hypoxia or other serious medical conditions. This elevated rate signals an urgent need for intervention and further evaluation.

A pregnant patient at 32 weeks gestation presents with painless, bright red vaginal bleeding. What condition should be suspected?

Answer: Placenta previa

Placenta previa causes painless bright red bleeding because the placenta overlies the cervical os and bleeds as the cervix changes.

You are transporting a 5-year-old child in respiratory distress. Which anatomical difference in a pediatric airway, compared to an adult, is most critical to consider when positioning the patient for basic airway management?

Answer: The occiput is proportionally larger.

In infants and young children, the proportionally larger occiput causes the neck to flex when the child is laid supine. [31] This flexion can obstruct the airway. To achieve a neutral or 'sniffing' position for optimal airway alignment, padding should be placed under the shoulders and torso to elevate the chest. [26, 31]

The revised trauma score (RTS) is calculated using which three parameters?

Answer: Glasgow Coma Scale, systolic blood pressure, and respiratory rate

The RTS combines GCS, systolic blood pressure, and respiratory rate, each coded and weighted to produce a score that correlates with survival probability.

A paramedic experiences symptoms of stress after a traumatic pediatric call. The BEST initial support intervention is:

Answer: Peer support and open communication with crew members

Immediate peer support and open communication are the first-line, evidence-supported interventions after a traumatic event.

After needle decompression of a tension pneumothorax, the patient's condition does not improve. What is the next step?

Answer: Perform a finger thoracostomy

If needle decompression fails to relieve tension pneumothorax, a finger thoracostomy provides a definitive prehospital decompression by creating an open chest wall opening.

A 45-year-old male presents with wheezing, urticaria, hypotension (BP 70/40), and stridor after eating shellfish. What is the FIRST drug to administer?

Answer: Epinephrine 0.3-0.5 mg IM

Epinephrine IM is the first-line treatment for anaphylaxis due to its immediate alpha and beta adrenergic effects.

The 'two-in/two-out' rule in rescue operations refers to:

Answer: Requiring two rescuers to enter any IDLH environment with two standby rescuers outside

OSHA's two-in/two-out rule mandates that at least two fully equipped rescuers stand by outside an IDLH atmosphere for every two who enter.

A 30-year-old unrestrained driver was involved in a high-speed frontal collision. The patient is pale, diaphoretic, and complaining of severe lower abdominal and hip pain. Palpation of the pelvis reveals instability. Vital signs are BP 88/50 mmHg and HR 128 bpm. What is the most appropriate initial intervention?

Answer: Apply a commercially approved pelvic binder or an improvised sheet sling.

The signs and symptoms strongly suggest an unstable pelvic fracture, which can cause massive internal hemorrhage. Applying a pelvic binder is a critical intervention to stabilize the pelvis, reduce the pelvic volume, and help tamponade bleeding. Log rolling can worsen the injury and increase bleeding and should be avoided.

During JumpSTART pediatric triage, if a child is apneic after repositioning the airway, the next step is to:

Answer: Give 5 rescue breaths and reassess

JumpSTART differs from START by giving 5 rescue breaths to apneic children before tagging black, recognizing children's respiratory-arrest potential for survival.

Which of the following patients is most in need of a rapid trauma assessment?

Answer: A young woman with a gunshot wound to the chest.

A rapid trauma assessment is performed on patients with significant mechanisms of injury or critical findings to quickly identify life-threatening conditions. A gunshot wound to the chest indicates a high-energy impact and potential for severe internal damage to vital organs, making it the most immediate and life-threatening scenario among the choices, thus requiring the most rapid assessment.

Which statement about performing CPR on a pregnant patient in cardiac arrest is correct?

Answer: Manually displace the uterus to the left while performing standard CPR

Left uterine displacement (LUD) relieves aortocaval compression and improves venous return during CPR in pregnancy.

What portion of the airway does gas exchange occur in?

Answer: Lower

Gas exchange, specifically the diffusion of oxygen into the blood and carbon dioxide out of the blood, occurs exclusively in the lower airway. This vital process takes place within the alveoli, which are tiny air sacs located at the ends of the bronchioles in the lungs. The upper airway primarily functions in air conduction and conditioning.

During a hazardous materials incident, what zone is designated as the area where decontamination occurs?

Answer: Warm zone

The warm zone (also called the contamination reduction zone) is where decontamination is performed between the hot and cold zones.

When approaching a vehicle collision scene at night, where should the rescue unit be positioned?

Answer: At an angle to the scene with lights illuminating the wreckage

Positioning the unit at an angle with lights aimed at the wreckage maximizes scene visibility while protecting rescuers from traffic.

A patient with blunt abdominal trauma has Kehr's sign (left shoulder pain). Which organ injury does this suggest?

Answer: Splenic rupture

Kehr's sign is referred pain to the left shoulder caused by diaphragmatic irritation from blood pooling under the left hemidiaphragm due to splenic rupture.

If the paramedic receives improper directions, what should they do?

Answer: Question them

If a paramedic receives directions that seem improper, unsafe, or unclear, they have a professional and ethical obligation to question them. Following improper directions could jeopardize patient safety, rescuer safety, or the success of the mission. It's crucial to seek clarification or alternative instructions rather than blindly proceeding.

A patient presents with urticaria, laryngeal edema, bronchospasm, and hypotension after eating shellfish. Which medication is the cornerstone of treatment?

Answer: Epinephrine 0.3 mg IM (1:1,000)

Epinephrine 1:1,000 administered IM into the lateral thigh is the first-line and potentially life-saving treatment for anaphylaxis, addressing bronchospasm and hypotension simultaneously.

Which sign is MOST reliable to confirm esophageal intubation in the field?

Answer: Flat waveform on continuous capnography

Continuous capnography waveform absence (flat line) is the most reliable indicator of esophageal intubation in the prehospital setting.

Which of the following correctly describes the Sellick maneuver and its current evidence-based status?

Answer: Cricoid pressure that may impair laryngoscopy view; not routinely recommended by current guidelines

Sellick maneuver (cricoid pressure) has not been proven to reliably prevent aspiration and can worsen laryngoscopy view; current evidence does not support routine use.
