You are dispatched to a reported unconscious person in a parking garage. Dispatch has limited information and cannot confirm whether the patient is alone. Which combination of pre-arrival actions reflects best practice?

Request law enforcement as a precaution and plan to assess the scene for hazards before approaching the patient

Correct Incorrect Correct answer

Proceed rapidly because unconscious patients have no airway protection and every second matters

Correct Incorrect Correct answer

Request hazmat because parking garages frequently contain carbon monoxide at dangerous levels

Correct Incorrect Correct answer

Ask dispatch to contact the patient by phone to confirm their level of consciousness

Correct Incorrect Correct answer

The primary purpose of gathering dispatch information while en route to a call is to:

Form a preliminary mental framework of the scene and likely patient needs before arrival

Correct Incorrect Correct answer

Determine the exact diagnosis so treatment can begin immediately on arrival

Correct Incorrect Correct answer

Decide whether the call warrants a response or can be handled by phone advice

Correct Incorrect Correct answer
