SECTION 1: MPDS FUNDAMENTALS AND CASE ENTRY
1. Which of the following represents the six links of the patient care Chain of Survival as
defined by the International Academies of Emergency Dispatch?
A. Recognition, CPR, Defibrillation, Advanced Care, Transport, Recovery
B. Recognition and response activation, Early CPR, Rapid defibrillation, Advanced resuscitation,
Post-cardiac arrest care, Recovery
C. Call intake, Dispatch, Response, On-scene care, Transport, Hospital care
D. Detection, Reporting, Response, Treatment, Transport, Rehabilitation
Answer: B
Explanation: The six links of the Chain of Survival are: (1) recognition and response activation,
(2) early CPR, (3) rapid defibrillation, (4) advanced resuscitation, (5) post-cardiac arrest care,
and (6) recovery. These links represent the critical interventions that maximize survival
outcomes for patients experiencing cardiac arrest.
2. What are the four priority symptoms that Emergency Medical Dispatchers must identify
during call intake?
A. Choking, heart attack, seizure, and stroke
B. Abnormal breathing, chest pain/discomfort, decreased level of consciousness, and serious
hemorrhage
C. Chief Complaint, patient's age, status of consciousness, and status of breathing
D. Medical, trauma, scene safety, and mechanism of injury
Answer: B
Explanation: The four priority symptoms are abnormal breathing, chest pain or discomfort,
decreased level of consciousness, and serious hemorrhage. These symptoms indicate potentially
life-threatening conditions and must be identified early in the call to ensure appropriate response
prioritization.
,3. According to MPDS standards, how should Emergency Medical Dispatchers verify the
address and callback number with the caller?
A. By repeating the information back to the caller verbatim
B. By asking the caller to spell the address and repeat the phone number
C. By confirming the information through automatic number identification only
D. By reading the information back and asking the caller to confirm its accuracy
Answer: D
Explanation: The International Academies of Emergency Dispatch recommends that dispatchers
verify the address and callback number by reading the information back and asking the caller to
confirm its accuracy. This ensures the information is correct and reduces the risk of dispatching
resources to the wrong location.
4. The Medical Priority Dispatch System (MPDS) is best described as:
A. A set of guidelines that dispatchers may follow at their discretion
B. A structured, medically approved protocol system that guides dispatchers through scripted
questions to determine response priority
C. A software program that automatically assigns response codes based on caller input
D. A training manual for emergency medical dispatchers
Answer: B
Explanation: MPDS is a structured, medically approved system that helps Emergency Medical
Dispatchers quickly identify the urgency of a call. It guides dispatchers through a series of
scripted questions whose answers reveal the presence or absence of priority symptoms, enabling
accurate prioritization and response assignment.
5. Which of the following is NOT one of the primary components of the MPDS?
A. Case Entry Protocol
B. Chief Complaint Protocols
C. Hospital Diversion Protocols
D. Diagnostic and Instruction Tools
, Answer: C
Explanation: The five primary components of the MPDS are: (1) Case Entry Protocol, (2) Chief
Complaint Protocols, (3) Diagnostic and Instruction Tools, (4) Pre-Arrival Instructions (PAIs),
and (5) Case Exit Protocols. Hospital Diversion Protocols are not a primary component of the
MPDS.
6. What is the correct sequence of actions when a caller reports that a patient is "on fire"?
A. Initiate Protocol 7-E-1 response, provide case entry PDIs A and H, and return to questioning
B. Initiate Protocol 6-B-1 response and provide CPR instructions
C. Initiate Protocol 30-Traumatic Injuries and assess for burns
D. Initiate Protocol 26-Sick Person and provide first aid instructions
Answer: A
Explanation: When a caller reports that a patient is on fire, the Emergency Medical Dispatcher
should initiate a 7-E-1 response (the highest priority for burns), provide case entry Post-Dispatch
Instructions A and H, and then return to the questioning process.
7. When a second-party caller cannot determine if the patient is breathing, the patient
should be:
A. Considered to be breathing normally until proven otherwise
B. Considered to be NOT BREATHING until proven otherwise
C. Asked to check for a pulse before making a determination
D. Transferred to a supervisor for further assessment
Answer: B
Explanation: When a second-party caller cannot tell if the patient is breathing or not, the patient
should be considered to be NOT BREATHING until proven otherwise. This conservative
approach ensures that potentially life-threatening situations are not underestimated.
