What is the third step in AED use?

• A. Turns on AED
• B. Clears for analysis, clears rescuers and allows the AED to analyze the heart rhythm
• C. Attaches pads
• D. Delivers a shock

Answer: (B)

The key idea here is that accurate rhythm analysis requires no one touching the patient. After the pads are in place and the AED is turned on, you must stand clear so the device can read the heart’s electrical activity without interference. This clearing step is what lets the AED determine whether a shock is needed. If the rhythm is found to be non-shockable, you’ll continue CPR as instructed; if a shock is advised, you’ll follow the prompts to deliver it. Turning on the AED happens first, and attaching the pads happens before analysis, while delivering a shock occurs only after the device indicates it’s appropriate. Clearing for analysis ensures the reading is reliable and keeps rescuers safe during the process.
