EMT Practice Questions

The correct answers are

A.  

Wear a safety vest,

B.  

Limit scene time, and

F.  

Park with wheels turned toward the scene.

Why A is correct (High-visibility vest):

EMS providers must wear ANSI-compliant reflective vests when operating on roadways

This significantly improves visibility, especially at night

NREMT-aligned guidance states:

“Wear high-visibility apparel when operating near traffic.”

Why B is correct (Limit scene time):

Reducing time on the roadway minimizes exposure risk

Rapid assessment, treatment, and transport are key safety strategies

“Minimize time spent in hazardous environments.”

Why F is correct (Wheel positioning):

Turning wheels toward the scene helps:

Prevent the ambulance from being pushed into responders if struck

Provide a protective barrier

“Position vehicles to protect the scene and personnel.”

Why the other options are incorrect:

C.  

Keep back turned to vehicles❌ Dangerous — EMTs should face traffic when possible

D.  

Place flares 10 feet away❌ Incorrect distance — flares should be placed much farther away for advance warning

E.  

Reduce scene lighting❌ Incorrect — proper lighting is essential for scene safety and visibility

Exact Extracts (NREMT-aligned EMT educational references):

“Use reflective safety vests when working on roadways.”

“Limit exposure time in hazardous scenes.”

“Position emergency vehicles to create a safe work zone.”

Clinical Priority Summary:

Key roadway safety measures include visibility, minimizing exposure, and proper vehicle positioning, making A, B, and F the correct answers.

The correct answers are

C.  

Bradycardia and

D.  

Altered mental status.

This question focuses on distinguishing respiratory distress from respiratory failure in pediatric patients.

Respiratory distress = compensating (early signs)

Respiratory failure = decompensating (late, life-threatening signs)

Why C is correct (Bradycardia):

In children, bradycardia is a late and ominous sign of hypoxia.

It indicates the patient is decompensating and nearing respiratory arrest.

Why D is correct (Altered mental status):

Indicates inadequate oxygenation and/or ventilation to the brain.

A hallmark of respiratory failure, not just distress.

Why the other options are incorrect:

A.  

Coughing → Nonspecific, not indicative of failure

B.  

Tachypnea → Early compensatory sign of respiratory distress

E.  

Increased work of breathing → Also an early sign of distress, not failure

Exact Extracts:

“Respiratory failure is indicated by altered mental status and signs of poor oxygenation.”

“Bradycardia in pediatric patients is a late sign of hypoxia.”

“Increased work of breathing and tachypnea are signs of respiratory distress.”
