EMT EMS Operations and Scene Safety

Question 1

What is the primary purpose of the 'scene size-up' performed by EMTs upon arrival?

Accepted Answer

To ensure scene safety and gather critical initial information

Answer

The scene size-up is performed first to ensure safety, identify hazards, determine the mechanism of injury, and gather information needed before patient care begins.

Question 2

When arriving at a potential crime scene where a victim is injured, what is the most appropriate action for EMTs?

Accepted Answer

Stage at a safe location until law enforcement clears the scene

Answer

EMTs should stage at a safe location and wait for law enforcement to secure a crime scene before entering, as an unsecured scene places the EMT at serious risk.

Question 3

An EMT arrives at a scene where a power line has fallen on a vehicle containing a trapped patient. What is the most appropriate initial action?

Accepted Answer

Stage at a safe distance and notify the power company and fire department

Answer

Downed power lines pose an extreme electrocution hazard; EMTs must maintain a safe distance and wait for the power company to de-energize the line before approaching.

Question 4

When parking an ambulance at a highway emergency scene, which positioning is generally considered safest?

Accepted Answer

Angled to create a traffic break, approximately 100–150 feet behind the incident

Answer

Positioning the ambulance at an angle 100–150 feet behind the incident creates a protective buffer zone and redirects traffic away from rescuers and patients.

Question 5

Which personal protective equipment (PPE) item is considered the minimum standard for ALL patient contacts?

Accepted Answer

Gloves

Answer

Gloves are the minimum PPE required for all patient contacts to prevent transmission of blood, body fluids, and other potentially infectious materials.
