Pros and Cons at a Glance

Sample Emergency Medical Dispatch Practice Questions

Try these questions from our free Emergency Medical Dispatch practice tests. The correct answer and an explanation follow each question.

1. With only one available unit and two simultaneous Priority 1 calls, what should primarily guide assignment?

   • A. The geographic area with historically higher call volume
   • B. The determinant code indicating the most immediately life-threatening condition
   • C. The caller's emotional state during interrogation
   • D. The crew's stated preference based on prior experience with similar calls

   Answer: B. The determinant code indicating the most immediately life-threatening condition

   Determinant codes objectively rank call severity, providing an evidence-based standard for prioritizing the single available unit.

2. When two Priority 1 calls arrive simultaneously, what should primarily guide the dispatcher's resource assignment decision?

   • A. The order in which calls were received
   • B. Geographic proximity of available units only
   • C. The nature and severity of each emergency based on determinant codes
   • D. The caller's ability to communicate clearly

   Answer: C. The nature and severity of each emergency based on determinant codes

   Determinant codes reflecting the nature and severity of each emergency drive resource priority when simultaneous calls compete for limited units.

3. A major highway pile-up involving multiple vehicles has been reported, and numerous calls are coming into the dispatch center. As an EMD, your primary role in resource allocation during the initial phase of this Mass Casualty Incident (MCI) is to:

   • A. Dispatch all available units to the scene immediately to ensure maximum resources are present.
   • B. Attempt to triage each individual patient over the phone using standard protocols.
   • C. Gather critical scene information, dispatch an initial appropriate response, and coordinate with command personnel.
   • D. Provide detailed post-dispatch instructions to every individual caller before dispatching any units.

   Answer: C. Gather critical scene information, dispatch an initial appropriate response, and coordinate with command personnel.

   In a Mass Casualty Incident, the EMD's role shifts from individual patient triage to a broader scene management support function. The key initial responsibilities are to understand the scope of the incident (location, number of vehicles, potential hazards), dispatch an appropriate initial response to establish command, and then act as a vital communication link for the incident commander. Individual telephone triage is impractical and inefficient in a large-scale MCI.

4. During a quality assurance case review, the practice of 'blinding' the reviewer primarily serves what purpose?

   • A. To conceal the identity of the EMD from the quality assurance reviewer.
   • B. To review the EMD's performance without knowledge of the patient's ultimate clinical outcome.
   • C. To prevent the EMD from knowing which of their calls are being selected for review.
   • D. To remove all patient-identifying information to comply with HIPAA regulations.

   Answer: B. To review the EMD's performance without knowledge of the patient's ultimate clinical outcome.

   Blinding in this context is designed to prevent 'outcome bias.' If a reviewer knows the patient had a negative outcome, they may subconsciously scrutinize the call more harshly. Conversely, knowing of a positive outcome might lead them to overlook minor deviations. Blinding the reviewer to the outcome ensures the EMD's performance is judged solely on their adherence to the established process and protocol.
