Question 1: When a caller reports a structure fire with possible victims inside, what is the FIRST action a dispatcher should take?
- Dispatch fire and EMS units immediately (Correct answer)
- Ask the caller to describe the building layout
- Verify the caller's identity before dispatching
- Instruct the caller to attempt a rescue
Correct answer: Dispatch fire and EMS units immediately
Immediate dispatch minimizes response time, which is the most critical factor when lives may be at risk.
Question 2: A caller reports a domestic disturbance then goes silent. What should the dispatcher do?
- Keep the line open and dispatch units while attempting communication (Correct answer)
- Hang up and attempt a callback
- Wait two minutes then disconnect the call
- Only dispatch if the caller resumes speaking
Correct answer: Keep the line open and dispatch units while attempting communication
An open line can capture background audio and provide scene intelligence even without verbal responses from the caller.
Question 3: What information is MOST critical to obtain FIRST when someone calls 911?
- Location of the emergency (Correct answer)
- Caller's full name
- Caller's callback number
- A detailed description of the incident
Correct answer: Location of the emergency
Location is the top priority because emergency responders cannot deploy to help without knowing where to go.
Question 4: When should a 911 dispatcher instruct a bystander to begin CPR?
- When an unresponsive adult is reported and EMS has not yet arrived (Correct answer)
- Only when a medical professional confirms it is needed
- Only after verifying the caller's identity
- Never — CPR guidance is strictly an EMS responsibility
Correct answer: When an unresponsive adult is reported and EMS has not yet arrived
Dispatcher-guided CPR improves cardiac arrest survival rates by initiating chest compressions before EMS arrives.

- Dispatch police only and have them assess for EMS need
- Dispatch EMS only since it is a medical emergency
- Wait for the caller to specify which agency is needed
Correct answer: Dispatch fire/EMS and law enforcement simultaneously
Multi-vehicle injury accidents require simultaneous medical and law enforcement response for scene safety and patient care.
Question 6: What is the recommended communication style for a dispatcher delivering pre-arrival emergency instructions?
- Calm, clear, and deliberate (Correct answer)
- Fast-paced to convey the urgency of the situation
- Authoritative and loud to override the caller's panic
- Casual and friendly to keep the caller relaxed
Correct answer: Calm, clear, and deliberate
A calm, clear, and deliberate tone helps panicked callers focus and follow life-saving instructions effectively.
