TOPIC 1: MPDS PROTOCOL STRUCTURE
8 Questions • 9.0% of Exam • Explores the hierarchical organization of MPDS protocols and their application in emergency scenarios.
QUESTION 1
During a medical dispatch, the EMD must evaluate the caller's description of "chest
pain radiating to the left arm". Which MPDS protocol element is primarily used to
determine the appropriate priority level?
[A] Chief Complaint Algorithm
[B] Secondary Assessment Checklist
[C] Medical Priority Dispatch Determinant Matrix
[D] Patient Age Modifier
Correct Answer: Medical Priority Dispatch Determinant Matrix.
Rationale: The Determinant Matrix cross-references chief complaint, symptom descriptors, and modifiers to assign the
correct priority.
QUESTION 2
Within the MPDS protocol structure, which determinant level is specifically designed to
capture the severity of the patient's condition when the chief complaint is cardiac in
nature?
[A] Determinant 1
[B] Determinant 2
[C] Determinant 3
[D] Determinant 4
Correct Answer: Determinant 3.
Rationale: Determinant 3 is the severity determinant for cardiac-related chief complaints, providing a granular assessment
of the patient's condition beyond the basic complaint captured in Determinant 1 and the general category in Determinant 2.

QUESTION 3
When implementing a new MPDS protocol, which sequence correctly reflects the
mandatory steps from call receipt to dispatch according to MPDS protocol structure?
[A] Identify chief complaint → Assign determinant codes → Apply axioms → Issue dispatch priority → Provide PDIs
[B] Apply axioms → Identify chief complaint → Provide PDIs → Assign determinant codes → Issue dispatch priority
[C] Identify chief complaint → Provide PDIs → Apply axioms → Assign determinant codes → Issue dispatch priority
[D] Assign determinant codes → Identify chief complaint → Apply axioms → Issue dispatch priority → Provide PDIs
Correct Answer: Identify chief complaint → Assign determinant codes → Apply axioms → Issue dispatch
priority → Provide PDIs.
Rationale: The MPDS implementation process begins with capturing the chief complaint, then coding determinants,
applying axioms to resolve conflicts, determining the appropriate priority, and finally delivering post-dispatch instructions.
QUESTION 4
Which MPDS method is employed to resolve ambiguous caller information that could
map to multiple determinant codes within the same protocol?
[A] Use the first determinant entered by the dispatcher.
[B] Apply the 'most severe determinant' rule.
[C] Default to Determinant 2 regardless of content.
[D] Ask the caller to repeat the information verbatim.
Correct Answer: Apply the 'most severe determinant' rule.
Rationale: The MPDS method for handling ambiguity is to select the determinant that reflects the highest severity, ensuring
patient safety and appropriate resource allocation.
