Detailed Rationales Based on NAEMD/IAED Standards |
MPDS Protocols | Latest 2026/2027 Updates
SECTION I: FOUNDATIONS OF EMERGENCY MEDICAL DISPATCH
1. The six links of the patient care chain of survival, as standardized by the
AHA and IAED, are:
- A) Recognition, CPR, Defibrillation, ALS, Recovery, Rehab
- B) Recognition and response activation, early CPR, rapid defibrillation,
advanced resuscitation, post-cardiac arrest care, recovery
- C) Call receipt, dispatch, response, treatment, transport, hospital handoff
- D) Scene safety, primary assessment, CPR, AED, transport, definitive care
Answer: B
Rationale: The Chain of Survival is standardized by the AHA/IAED. Link 5 is
specifically "post-cardiac arrest care" and Link 6 is "recovery," reflecting
updated 2020 guidelines that emphasize recovery as a distinct phase. The
other options do not accurately reflect the six links as defined by current
standards.
,2. True or False: EMDs are trained medical professionals.
- A) True
- B) False
Answer: A
Rationale: EMDs are certified medical dispatchers trained in MPDS protocols.
They function as an extension of EMS and are considered the "first" first
responder, providing initial medical assessment via telephone.
3. Which of the following best describes the primary role of an Emergency
Medical Dispatcher (EMD)?
- A) To provide on-scene medical treatment
- B) To act as the first point of medical assessment and resource activation
- C) To transport patients to the hospital
- D) To document patient vital signs after arrival
Answer: B
Rationale: The EMD is the "first" first responder, performing initial assessment
via the phone and dispatching appropriate EMS resources. The EMD does not
provide on-scene treatment (A), transport patients (C), or document vital
signs after arrival (D).
,4. In the EMS system, where does the EMD fit most accurately?
- A) Directly after the ambulance arrives on scene
- B) Between the 911 call taker and the EMS field crew
- C) As part of the hospital emergency department staff
- D) Within the medical director's office only
Answer: B
Rationale: The EMD receives the emergency call, gathers information, and
then activates EMS crews, linking the public to field responders.
5. What is the first step an EMD should take when answering a 911 call?
- A) Ask the caller's name and location immediately
- B) Identify the type of emergency before greeting
- C) Say "911, what is your emergency?" and verify the line is clear
- D) Begin dispatching units before gathering information
Answer: C
Rationale: The EMD must answer promptly, confirm the line is clear, and
initiate the standardized greeting to start the interrogation.
, 6. When dealing with an angry caller, the EMD should primarily:
- A) Transfer the call to a supervisor immediately
- B) Hang up and request a callback
- C) Use active listening, calm tone, and reassurance while maintaining control
- D) Ignore the caller's emotions and proceed with questions
Answer: C
Rationale: De-escalation techniques, such as active listening and a calm
demeanor, help maintain control and gather needed information.
7. What does MPDS stand for?
- A) Medical Priority Dispatch System
- B) Medical Priority Data System
- C) Medical Pre-Dispatch System
- D) Medical Protocol Decision System
Answer: A
Rationale: MPDS is the standard protocol system used by EMDs to triage and
handle medical emergency calls.
