✍️ Sample 911 Operator Test Questions & Answers

1. When providing pre-arrival instructions to a caller for a medical emergency, why is it critical for a 911 operator to use plain, clear language instead of technical medical terms or jargon?
To prevent panic and ensure the caller can understand and correctly follow life-saving directions without confusion.

During a high-stress event, a caller's ability to process complex information is diminished. Using simple, direct language ensures that instructions for actions like CPR or bleeding control are understood and performed correctly. Technical jargon can cause confusion, hesitation, or incorrect actions, potentially worsening the patient's outcome. The primary goal is caller comprehension for patient benefit.

2. What does '10-20' typically mean in police radio codes?
Location

10-20 is a standard radio code used to request or state a unit's current location.

3. There are 5 stages in the communications cycle. Which section is the content reference?
Message

In the communications cycle, the 'message' refers to the actual content or information being conveyed from the sender to the receiver. It is the substance of the communication, encompassing the ideas, facts, or feelings intended to be transmitted. The other components like receiver, medium, and feedback describe how the message is processed, delivered, and understood.

4. You discover that someone on your street tampered with utility cables in order to use electricity without paying for it. Which number do you need to call to report this?
Telephone Crime Reporting Unit (313)267-4600

Tampering with utility cables to steal electricity, while illegal, is typically not an immediate life-threatening emergency. It's a crime that requires investigation but doesn't demand the urgent, on-the-spot response of 911. Reporting it to a dedicated crime reporting unit allows for proper investigation without tying up emergency lines.

5. When should a 911 dispatcher instruct a bystander to begin CPR?
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.

6. Telecommunicators must be able to tell when a piece of information is inappropriate. All of the following are acceptable, but not:
Listen to the caller only, block out all background noises

While active listening is crucial for a telecommunicator, completely blocking out background noises is often impossible and can be counterproductive. Background sounds can provide vital contextual information about an emergency, such as the presence of sirens, screams, or specific environmental cues. A skilled telecommunicator learns to filter and interpret these sounds while focusing on the caller's voice, rather than ignoring them entirely.
