Question

a 53 - year - old man collapses and becomes unresponsive. you witness his collapse and are the first rescuer at the scene, where the man is lying motionless on the floor. which is the first action you should take in this situation?
start providing rescue breaths
verify that the scene is safe for you and the victim
start high - quality cpr, beginning with chest compressions
activate the emergency response system

Explanation:

When responding to an unresponsive person, the first step is to ensure the safety of both the rescuer and the victim. If the scene is unsafe (e.g., there are electrical wires down, a fire nearby), attempting to rescue the victim could put both the rescuer and the victim in further danger. Only after confirming scene safety can other steps like activating the emergency response system, starting CPR, or providing rescue breaths be considered.

Answer:

Verify that the scene is safe for you and the victim
