✍️ Sample EMD Questions & Answers
1. An EMD receives a call about a child who ingested a household chemical. The appropriate protocol is:
Ingestion of any toxic substance, including household chemicals, is managed under the Overdose/Poisoning protocol.
2. What is the primary advantage of MPDS over purely ad hoc, experience-based emergency dispatching?
Standardized protocols ensure every caller receives consistent, evidence-based assistance and provide dispatchers with a documented, defensible decision framework.
3. A mother calls and reports that her 2 year old daughter accidentally ingested a small amount of bleach and is conscious and breathing, choose the most correct chief complaint.
The most correct chief complaint in this situation would be "23 Overdose/Poisoning" because the child accidentally ingested bleach, which is a toxic substance. Although the child is conscious and breathing, ingesting bleach can still be considered an overdose or poisoning and requires immediate medical attention.
4. What is the primary function of Post-Dispatch Instructions (PDIs) within the Medical Priority Dispatch System?
Post-Dispatch Instructions (PDIs) are given to the caller after the initial dispatch has been made. Their main purpose is to guide the caller in preparing for the arrival of help, which can include actions like unlocking the door, securing pets, and turning on lights to make the location easier to find.
5. When a dispatcher assigns a response of 'Code 2' (no lights or siren), which determinant level most likely applies?
Alpha-level determinants typically correspond to non-urgent or low-acuity calls where a routine, non-emergency response is appropriate.
6. When interrogating a third-party caller who is not at the scene, what is the dispatcher's most critical challenge?
Third-party callers relay secondhand information, meaning details about breathing, consciousness, and injury severity may be inaccurate or incomplete.
