Which special circumstance while using an AED is addressed correctly?

Using an AED effectively requires considering special circumstances to ensure proper function and safety. Shaving a hairy chest before applying AED pads is a necessary step when there is excessive chest hair that can prevent good contact between the pads and the skin. If the pads cannot adhere properly, the electrical shock may not be delivered effectively, compromising the chances of restoring a normal heart rhythm. By shaving the chest, it ensures that the pads are placed directly on the skin, maximizing the AED's effectiveness in a critical situation.

In contrast, using an AED while the victim is still in water can increase the risk of electric shock to both the victim and the rescuer, making it an unsafe practice. While removing jewelry seems prudent, it isn't always necessary, particularly if the jewelry does not interfere with pad placement or if a medical professional deems it safe. Likewise, turning the AED on before attaching the pads does not follow recommended guidelines, as the device should be activated to analyze the heart rhythm only when the pads are in place. Each of these other scenarios highlights the importance of ensuring the AED operates optimally while maintaining safety for both the victim and the responder.
