Which component of the EMS communication system is responsible for receiving emergency calls from the public and dispatching resources?
Answer: Public Safety Answering Point (PSAP)
A PSAP (Public Safety Answering Point) is the facility that receives 9-1-1 calls and coordinates dispatch of EMS, fire, and police.
What does 'duplex' mean in the context of EMS radio communications?
Answer: The ability to transmit and receive on different frequencies at the same time
Duplex operation allows simultaneous two-way communication by using separate transmit and receive frequencies, similar to a telephone conversation.
A paramedic must give a verbal report to the emergency department nurse upon arrival. Which element should be communicated LAST?
Answer: Interventions performed and patient response
Interventions and patient response are typically communicated at the end to give the receiving team the most current clinical picture before transfer of care.
Which term refers to the process of confirming that a message was received and understood correctly?
Answer: Echo procedure
The echo procedure (read-back/repeat-back) requires the receiver to repeat critical information to confirm accurate receipt of the message.
When is it appropriate to use 'plain language' rather than 10-codes in EMS communications?
Answer: Always, as recommended by NIMS for interoperability
NIMS recommends plain language at all times to ensure clear communication and interoperability among multiple agencies.
A mobile data terminal (MDT) in an EMS unit primarily provides:
Answer: Text-based dispatch and mapping information to the crew
MDTs provide text-based dispatch data, mapping, and supplemental information to the crew without occupying the voice radio channel.
Which practice helps prevent radio frequency interference during a multi-agency incident?
Answer: A dedicated interoperability channel is assigned and all agencies switch to it
Assigning a designated interoperability (interop) channel allows multiple agencies to coordinate on a single, agreed-upon frequency.
