Which cue indicates a change of rescuers at the start of the CPR cycle?

• A. Shout 'Time Out'
• B. Raise a hand
• C. Say 'Switch'
• D. Tap the partner's shoulder

Answer: (C)

The important idea here is coordinating a smooth hand-off between rescuers so chest compressions stay continuous. Saying “Switch” is the clearest cue to indicate it’s time for the other person to take over and start compressions. It’s explicit, audible, and unambiguous, which helps prevent delays or confusion in a noisy environment. Other cues like raising a hand, tapping the shoulder, or shouting “Time Out” don’t clearly signal the start of the new CPR cycle or could be missed or mistaken for a pause; a verbal switch keeps the transition clean and immediate.
