Answer: The rescuer operating the AED should clear the victim before delivering a shock.
Explanation: It is crucial to ensure that no one is touching the victim when the AED is about to deliver a shock. This is to prevent any accidental transmission of the electrical shock to the rescuer or bystanders, which could cause harm. The rescuer should loudly announce “Clear!” and visually confirm that everyone has stepped back before pressing the shock button on the AED. This step is vital for the safety of everyone involved and to ensure the shock is delivered effectively to the victim.
