What is a characteristic of the EMS system?

The EMS system is designed to provide comprehensive care to patients from the initial call for help all the way through to the rehabilitation process after emergency medical treatment. This includes a variety of roles and responsibilities, beginning with call-takers who assess the situation and prioritize calls, dispatch emergency responders, and provide pre-arrival instructions to callers. After patient care is delivered at the scene and during transport, rehabilitation services play a crucial role in the recovery process. This holistic approach ensures that the EMS system not only responds to emergencies but also encompasses the full continuum of care for the patient, making option B the most accurate characterization of the EMS system.
