Canadian Red Cross Basic Life Support (BLS) Practice Test, Prep & Study Guide

When the AED instructs you to stand clear, the correct action is to step back and ensure that no one is touching the patient. This is crucial because the AED delivers a shock that can cause serious harm or injury to anyone in contact with the patient at that moment. Standing clear ensures that the shock is delivered safely and effectively to the patient without any risk of harm to bystanders.

The AED issues this command to guarantee that the electrical shock is delivered solely to the patient, allowing the device to have the intended effect on the heart while minimizing any potential for unintended consequences. The patient's safety and successful delivery of the shock depend on this clear instruction being followed precisely.
