NREMT Updated EMT Exam Questions and Answers by antonina

The correct answer is B. Left lateral recumbent.

This patient has return of spontaneous circulation (ROSC) but remains unresponsive. In such cases, airway protection becomes the priority.

According to NREMT and resuscitation guidelines:

Unresponsive patients who are breathing adequately should be placed in the recovery position (lateral recumbent) to maintain a patent airway and reduce the risk of aspiration.

This position allows secretions or vomit to drain out of the mouth instead of entering the airway.

Why B is correct:

“Place unresponsive patients with adequate breathing in the recovery position.”

The left lateral recumbent position is the standard recovery position used in EMS.

Why the other options are incorrect:

A. Supine: Increases risk of airway obstruction and aspiration in an unresponsive patient.

C. Trendelenburg: Not recommended; can worsen respiratory function and does not improve outcomes.

D. Head elevated 45°: May be used in conscious patients or certain conditions, but not ideal for an unresponsive patient without airway control.

Exact Extracts:

“Unresponsive patients who are breathing adequately should be placed in the recovery position.”

“The recovery position helps maintain an open airway and reduces aspiration risk.”

“Airway management is the priority after ROSC.”

The diaphragm is innervated by the phrenic nerve, which originates from spinal nerve roots C3–C5. NREMT teaching highlights the phrase: “C3, 4, and 5 keep the diaphragm alive.”

Option A (C4) is correct because an injury at or above this level can paralyze the diaphragm, resulting in apnea and immediate respiratory failure.

Option B (T1) and C (T3) affect intercostal muscles but not the diaphragm.

Option D (L4) affects lower extremity function only.

NREMT emphasizes that high cervical spine injuries are immediately life-threatening due to loss of ventilatory control.

The correct answer is C because a surgical mask provides source control by helping limit the spread of respiratory droplets from a coughing patient. Official CDC infection-control guidance states that if possible, a surgical mask should be placed on the patient to contain droplets expelled during coughing , and patients on droplet precautions should wear a mask if tolerated. This matches EMT operations and infection-control principles tested in NREMT-style questions.

CDC also explains that source control means using a mask or respirator to cover the patient’s mouth and nose to help prevent spread of respiratory secretions. In this question, the purpose of placing a mask over or around the nebulizer setup is to reduce droplet spread to others , not to improve medication delivery.

Comprehensive and Detailed Explanation (Based on NREMT standards):

Electrical injuries commonly disrupt the heart’s electrical conduction system. NREMT teaching emphasizes that cardiac dysrhythmias are the leading cause of unresponsiveness following electrical exposure, even when external burns appear minor.

Option A is correct because electrical current can induce lethal dysrhythmias such as ventricular fibrillation or asystole, resulting in sudden loss of consciousness.

Option B is incorrect because internal bleeding is not a primary consequence of electrical injury.

Option C may occur but does not typically cause immediate unresponsiveness.

Option D is less likely than cardiac involvement and is not the most common cause.

NREMT stresses continuous cardiac monitoring and rapid transport for all electrical injury patients due to the high risk of sudden cardiac arrest.
