Question

what action should you take when more rescuers arrive?
wait for the most experienced rescuer to provide direction to the team
continue cpr while the aed is attached, even if you are fatigued
assign tasks to other rescuers and rotate compressors every 2 minutes or more frequently if needed to avoid fatigue
direct the team to assign a team leader and roles while you continue cpr

Explanation:

When more rescuers arrive during a CPR situation, it is important to efficiently utilize the additional help. Waiting for the most experienced rescuer (option 1) may waste time. Continuing CPR while fatigued (option 2) can lead to ineffective compressions. Directing the team to assign a leader while continuing CPR (option 4) is not the best use of additional rescuers. Assigning tasks and rotating compressors (option 3) ensures optimal performance and prevents fatigue.

Answer:

Assign tasks to other rescuers and rotate compressors every 2 minutes or more frequently if needed to avoid fatigue.
