EMD Medical Priority Dispatch System 4

Question 1

What is the foundational MPDS principle regarding when to dispatch units relative to caller interrogation?

Accepted Answer

Dispatch appropriate units first, then continue gathering information and providing instructions

Answer

MPDS follows a 'dispatch first' principle so resources are moving toward the scene while the dispatcher continues questioning and giving instructions.

Question 2

Which patient presentation would prompt MPDS Telephone CPR (T-CPR) instructions from a dispatcher?

Accepted Answer

A patient who is unresponsive and not breathing normally

Answer

T-CPR instructions are initiated when the patient is unresponsive and not breathing normally, indicating probable cardiac arrest.

Question 3

For an untrained bystander, which CPR method does MPDS recommend a dispatcher instruct?

Accepted Answer

Compression-only (hands-only) CPR

Answer

Compression-only CPR is recommended for untrained bystanders because it is simpler to perform and still significantly improves cardiac arrest outcomes.

Question 4

For a responsive patient with a suspected complete airway obstruction due to choking, MPDS directs dispatchers to instruct bystanders to perform:

Accepted Answer

Abdominal thrusts (Heimlich maneuver)

Answer

Abdominal thrusts are the correct intervention for a conscious, responsive patient with a complete airway obstruction.

Question 5

In MPDS, Post-Dispatch Instructions (PDIs) are given during which time frame?

Accepted Answer

After dispatch is made, while EMS units are en route to the scene

Answer

PDIs are provided after units are dispatched to keep callers informed, calm, and prepared until EMS arrives on scene.
