EMT EMS Operations and Scene Safety 1 — Questions and Answers
Question 1: What is the primary purpose of the 'scene size-up' performed by EMTs upon arrival?
- To determine the number of patients present
- To ensure scene safety and gather critical initial information (Correct answer)
- To begin patient assessment immediately
- To request additional EMS resources
Correct answer: To ensure scene safety and gather critical initial information
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?
- Enter immediately to provide patient care
- Stage at a safe location until law enforcement clears the scene (Correct answer)
- Contact medical direction before approaching
- Don full PPE and enter cautiously
Correct answer: Stage at a safe location until law enforcement clears the scene
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?
- Approach carefully on dry ground
- Use rubber gloves to move the power line away
- Stage at a safe distance and notify the power company and fire department (Correct answer)
- Instruct the patient to exit the vehicle immediately
Correct answer: Stage at a safe distance and notify the power company and fire department
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?
- Directly behind the incident to block all traffic
- Angled to create a traffic break, approximately 100–150 feet behind the incident (Correct answer)
- On the opposite side of the highway
- Adjacent to the incident perpendicular to traffic flow
Correct answer: Angled to create a traffic break, approximately 100–150 feet behind the incident
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?
- Gown and surgical mask
- Gloves (Correct answer)
- Eye protection and gown
- N95 respirator
Correct answer: Gloves
Gloves are the minimum PPE required for all patient contacts to prevent transmission of blood, body fluids, and other potentially infectious materials.
Question 6: Who is typically responsible for direct patient care when transporting a patient in the back of an ambulance?
- The ambulance driver
- The EMT attendant in the patient compartment (Correct answer)
- Online medical direction
- The charge nurse at the receiving facility
Correct answer: The EMT attendant in the patient compartment
The EMT attendant in the patient compartment is responsible for monitoring and providing all care to the patient throughout transport.
Question 7: Upon arriving at a motor vehicle collision involving 15 patients, which management system should be initiated?
- Incident Command System (ICS) (Correct answer)
- Standard two-person trauma protocol
- Mass decontamination protocol
- Advanced life support escalation protocol
Correct answer: Incident Command System (ICS)
The Incident Command System (ICS) should be initiated at mass casualty incidents to establish a clear command structure and coordinate multiple resources effectively.
