What are the proper actions for the lifeguard to take after the emergency action plan has been activated for someone who appears to be having a cardiac arrest in the water?

Removing the victim from the water and preparing to begin CPR or using an AED is the correct course of action when a cardiac arrest is suspected. In a drowning situation, time is critical, and immediate intervention is necessary to increase the chances of survival. By safely taking the individual out of the water, the lifeguard can ensure they are on a stable surface where CPR can be performed effectively without the complications that could arise from performing such techniques in the water.

Moreover, once the victim is on land, the lifeguard can quickly assess the situation further and utilize any available AED as soon as possible, which is crucial for restoring normal heart rhythm. This prompt action is crucial, as cardiac arrest requires immediate attention, and delays can significantly reduce the chances of a positive outcome.

Other actions, such as leaving the victim in the water, waiting for assistance, or administering first aid without removing the victim, are not aligned with best practices for treating a cardiac arrest. Immediate removal and resuscitation efforts are vital components of effective emergency response in such scenarios.
