  1. A crew member reports that transmissions are becoming garbled and intermittent as they move further from the city. This is most likely due to:

    Answer: Operating beyond the radio's effective range

    Garbled and intermittent transmissions at increasing distance indicate the unit is approaching or exceeding the radio's effective range.

  2. Which of the following is an example of a closed-ended question appropriate for radio communication?

    Answer: 'Is the patient conscious and breathing?'

    Closed-ended questions that elicit a 'yes' or 'no' answer are preferred on radio to save time and reduce misunderstandings.

  3. Under the Incident Command System (ICS), which position has overall responsibility for the communications function at a scene?

    Answer: Logistics Section Chief

    Under ICS, communications falls under the Logistics Section, specifically the Service Branch's Communications Unit.

  4. A paramedic hears a transmission beginning with 'Mayday, Mayday, Mayday.' What does this signal require?

    Answer: Immediate cessation of all non-emergency traffic and priority response

    A Mayday call signals a life-threatening emergency and requires all other traffic to clear the channel immediately for priority response.

  5. When a paramedic says 'affirmative' on the radio instead of 'yes,' they are following which communication principle?

    Answer: Clear-word radio discipline to avoid misinterpretation

    'Yes' can be misheard as 'S' on a noisy channel, while 'affirmative' is distinct and unambiguous, improving accuracy in voice communications.

  6. Which regulation governs the licensing and use of radio frequencies by EMS agencies in the United States?

    Answer: FCC Part 90 rules

    FCC Part 90 rules govern private land mobile radio services, including EMS radio licensing and frequency use.

  7. A paramedic's portable radio fails mid-call in a structurally compromised building. The best immediate action is:

    Answer: Exit to a location where radio contact can be re-established or use a cellular phone

    When a radio fails in a hazardous location, the paramedic should move to a safe area to re-establish communication via another radio or cell phone.
