Read the first 7 Prioritization and Dispatch flashcards as text

  1. In the Medical Priority Dispatch System (MPDS), which determinant level indicates the highest priority requiring an immediate life-threatening response?

    Answer: Delta

    Delta is the highest MPDS priority level, indicating a life-threatening situation requiring the fastest possible response.

  2. A caller reports a 45-year-old male who is unresponsive and not breathing. Which MPDS determinant suffix would most likely apply?

    Answer: D – Delta

    Cardiac and respiratory arrest cases default to a Delta-level determinant because they represent immediately life-threatening emergencies.

  3. What does the Omega determinant level signify in MPDS?

    Answer: Non-emergency referral or self-care

    Omega indicates a non-emergency situation where the caller can be referred to self-care or a non-emergency resource without an ambulance response.

  4. When a caller cannot confirm whether the patient is conscious and breathing, the dispatcher should initially assign which response level?

    Answer: The highest possible level until information is confirmed

    EMD protocol requires dispatching at the highest defensible priority when life-threatening status cannot be ruled out, then downgrading if warranted.

  5. A Bravo-level MPDS determinant typically requires which type of response?

    Answer: Potentially serious but non-life-threatening response

    Bravo-level calls are serious but not immediately life-threatening, so a prompt but not necessarily code-3 response is appropriate per local protocol.

  6. Which factor most directly determines the dispatch priority level assigned in MPDS?

    Answer: The determinant code derived from protocol questioning

    The MPDS determinant code, reached through systematic protocol-driven questioning, is the primary driver of the assigned priority level.

  7. In EMD, 'pre-arrival instructions' are provided primarily to:

    Answer: Improve patient outcomes by initiating care before EMS arrives

    Pre-arrival instructions empower bystanders to begin life-saving interventions such as CPR or hemorrhage control before the ambulance arrives.
