Which activity does NOT typically occur while en route to the scene of an emergency call?

The activity that does not typically occur while en route to the scene of an emergency call is briefing the medical director on incident specifics. This process usually involves detailed communication that can ensure good patient care and operational efficiency, but is not feasible to conduct in the moving ambulance. Time en route is often limited and focuses on preparing for the response, rather than engaging with external personnel.

On the other hand, reviewing the patient’s medical history, donning personal protective equipment, and preparing necessary equipment are standard activities that EMS personnel undertake during transit to the scene. Reviewing medical history helps responders anticipate patient needs, while donning protective gear ensures safety from potential exposures. Preparing equipment ensures that responders are ready to provide care immediately upon arrival. Therefore, the emphasis during transit is on readiness and safety, rather than detailed briefings with medical directors.
