NREMT Updated EMT Exam Questions and Answers by iona

The correct answer is C. Assess ventilatory adequacy.

This scenario indicates that the patient has achieved Return of Spontaneous Circulation (ROSC):

Presence of a strong carotid pulse (rate 67)

Patient is groaning, indicating some level of neurological responsiveness

At this point, the patient is no longer in cardiac arrest, so CPR should be stopped and the EMT must immediately reassess Airway and Breathing.

According to NREMT-aligned resuscitation priorities:

After ROSC, providers must “reassess airway, breathing, and circulation”

The next step is to determine if the patient is breathing adequately and provide ventilatory support if needed

Why C is correct:

Even though the patient has a pulse, breathing may still be inadequate

Groaning does not equal effective breathing

The EMT must immediately evaluate ventilatory status and assist respirations if necessary

Why the other options are incorrect:

A. Initiate rapid transport: Transport is important but comes after stabilization of airway and breathing

B. Hyperventilate the patient: Hyperventilation is harmful and not indicated; proper ventilation must first be assessed

D. Place the patient on a long backboard: Not relevant to the immediate life threat and no trauma is indicated

Exact Extracts (NREMT-aligned EMT educational references):

“If a pulse returns, reassess airway and breathing immediately.”

“Ensure adequate ventilation in patients with spontaneous circulation.”

“Do not assume adequate breathing—assess ventilatory status.”

Clinical Priority Summary:

Once ROSC occurs, the EMT must immediately reassess ABCs, with priority on airway and breathing, making assessment of ventilatory adequacy the next critical step.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Upon arrival, EMTs must immediately perform a scene size-up, which focuses on safety and incident management rather than patient treatment.

Option A (Identifying hazards) is correct because recognizing dangers such as traffic, fire, violence, or hazardous materials is essential to prevent responder injury.

Option E (Requesting additional resources) is correct because early recognition of the need for more personnel, ALS support, fire services, or law enforcement improves patient outcomes and scene control.

Option B is incorrect because ruling out life threats occurs during the primary assessment, not immediately upon arrival.

Option C is incorrect because patient treatment must wait until scene safety is confirmed.

Option D is incorrect because PPE use is a personal responsibility, not a primary scene-arrival task.

NREMT stresses that effective EMS operations begin with safety, situational awareness, and resource management.

The correct answers are B. Apply continuous positive airway pressure (CPAP) and D. Administer a beta-2 agonist.

This patient is in moderate to severe respiratory distress with:

Tachypnea (R 30)

Hypoxia (SpO₂ 89%)

Wheezing → indicates bronchoconstriction (asthma/COPD exacerbation)

Why B is correct (CPAP):

CPAP helps keep alveoli open, improves oxygenation, and reduces work of breathing.

It is indicated in patients who are awake, breathing, and in respiratory distress with hypoxia.

Especially beneficial in COPD exacerbations.

Why D is correct (Beta-2 agonist):

Beta-2 agonists (e.g., albuterol) relax bronchial smooth muscle, relieving wheezing and bronchospasm.

This directly treats the underlying problem in asthma/COPD exacerbation.

Why the other options are incorrect:

A. 3 LPM nasal cannula → Too low for significant hypoxia (SpO₂ 89%); patient needs more aggressive support

C. Recovery position → Used for unconscious patients, not alert patients in respiratory distress

E. Rescue breathing → Indicated for inadequate respirations, but this patient is breathing (though rapid)

Exact Extracts:

“CPAP is indicated for patients with respiratory distress who are breathing spontaneously.”

“Beta-agonists are used to relieve bronchospasm in asthma and COPD.”

“Patients with wheezing benefit from bronchodilator therapy.”

The correct answer is D. 60 seconds.

This question is testing the special consideration of hypothermia in cardiac arrest assessment. In a patient found unresponsive in the snow, there is a high likelihood of severe hypothermia, which significantly slows metabolism and heart rate.

In hypothermic patients, pulses may be very slow and difficult to detect, so the EMT must take extra time to accurately determine whether a pulse is present before initiating CPR.

Standard pulse checks in normothermic patients are limited to no more than 10 seconds, but hypothermic patients are an exception.

Why 60 seconds is correct:

NREMT-aligned EMS guidelines emphasize that in severe hypothermia, the provider should assess the pulse for up to 60 seconds before concluding that the patient is pulseless. This is because hypothermia can produce extremely slow heart rates (bradycardia), and premature CPR could be inappropriate if a pulse is actually present.

Why the other options are incorrect:

A. 10 seconds: This is correct for standard cardiac arrest assessment in normothermic patients, but not for hypothermia.

B. 15 seconds and C. 30 seconds: These are not recommended durations in NREMT or AHA guidelines for pulse checks.

Exact Extracts:

“In a hypothermic patient, check the pulse for 30–60 seconds before determining pulselessness.”

“Severely hypothermic patients may have very slow heart rates that are difficult to detect.”

“Do not assume cardiac arrest until a careful and prolonged pulse assessment has been performed.”
