Prior to using an AED, what should rescuers ensure?

Rescuers should ensure that the scene is clear of bystanders prior to using an AED because safety is paramount during an emergency situation. By having a clear area, rescuers can focus on the victim without distractions or risks posed by bystanders who may inadvertently interfere. Additionally, it ensures that there is no risk of bystanders inadvertently getting shocked from the device, especially during the defibrillation process, which requires the victim to be completely isolated from others. This precaution helps to ensure that the rescuer can perform the necessary procedures effectively and without interruption.

The other options do not directly address the immediate safety and effectiveness of using the AED. Ensuring the victim is conscious is irrelevant as AEDs are used on unconscious victims, while confirming the AED is fully charged is important but secondary to ensuring scene safety. Having other rescuers present can be beneficial, but it is not as critical as securing the area around the victim.
