✍️ Sample EMD Questions & Answers

1. An EMD receives a call about a child who ingested a household chemical. The appropriate protocol is:
Overdose/Poisoning

Ingestion of any toxic substance, including household chemicals, is managed under the Overdose/Poisoning protocol.

2. When a caller asks how hard to push during chest compressions, the EMD should instruct them to compress the chest:
At least 2 inches (5 cm) deep but no more than 2.4 inches

AHA guidelines specify 2–2.4 inches (5–6 cm) of compression depth for adequate cardiac output without excessive sternum force.

3. What is the primary advantage of MPDS over purely ad hoc, experience-based emergency dispatching?
Consistency, error reduction, and enhanced medico-legal protection for dispatchers and agencies

Standardized protocols ensure every caller receives consistent, evidence-based assistance and provide dispatchers with a documented, defensible decision framework.

4. During a DLS call, the caller states the patient has started breathing normally after CPR was performed. The dispatcher should instruct the caller to:
Place the patient in the recovery position and continue to monitor breathing

Once the patient is breathing adequately, place them in the recovery position (lateral) to protect the airway and monitor until EMS arrives.

5. 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.
23 Overdose/Poisoning

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.

6. What is the primary function of Post-Dispatch Instructions (PDIs) within the Medical Priority Dispatch System?
To provide instructions for the caller to prepare for the arrival of responders.

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.
