NREMT Updated EMT Exam Questions and Answers by uthman

The correct answers are A, C, and E because this patient is experiencing suspected acute coronary syndrome (ACS) with hypoxia (SpO₂ 88%) and borderline hypotension .

Aspirin is indicated in suspected cardiac chest pain to reduce platelet aggregation and improve outcomes.

Oxygen is appropriate because the SpO₂ is below 94% , indicating hypoxemia.

Position of comfort (usually sitting upright) helps reduce cardiac workload and improves breathing.

NREMT guidelines emphasize treating hypoxia, reducing cardiac workload, and administering aspirin early in suspected ACS.

CPAP is not indicated due to low blood pressure (92 systolic) , and AED use is not appropriate because the patient is not in cardiac arrest.

Comprehensive and Detailed Explanation (Based on NREMT standards):

When a previously choking adult becomes unresponsive, NREMT guidelines require the EMT to immediately begin the cardiac arrest sequence.

Option A (Check for a pulse) is correct because determining pulselessness directs the next intervention.

Option B (Begin chest compressions) is correct because chest compressions are initiated if the patient is pulseless and unresponsive. Compressions may also help dislodge the foreign body.

Option C is incorrect because the airway is checked only after compressions begin and ventilations are attempted.

Option D is incorrect because ventilations are attempted after compressions, with airway checks between cycles.

Option E is inappropriate for an unresponsive adult.

NREMT emphasizes following BLS algorithms precisely for airway obstruction leading to unresponsiveness.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Hepatitis A is a viral liver infection transmitted primarily through the fecal-oral route, often due to contaminated food, water, or poor hand hygiene. NREMT education highlights hepatitis transmission routes as part of infection control and standard precautions.

Option A is correct because hepatitis A spreads when microscopic amounts of fecal matter are ingested, commonly in environments with inadequate sanitation.

Options B, C, and D are incorrect because these forms of hepatitis are transmitted primarily through blood and body fluids, such as needlestick injuries, sexual contact, or shared needles.

Understanding transmission routes allows EMTs to apply proper protective measures and reduce occupational exposure risks, a core component of NREMT infection-control training.

This is a classic presentation of hypovolemic shock due to traumatic blood loss (open femur fracture, pelvic instability). Indicators include:

Low BP (86/42) = hypotension

High pulse (P 136) = compensation

Mental status decline (responsive only to voice) = indicates decompensated shock

Obstructive and distributive shock are not applicable. Compensated shock would show normal BP and alert mental status.
