In an adult, which pulse should be checked during CPR protocol?

• A. Carotid pulse in neck
• B. Radial pulse
• C. Brachial pulse
• D. Femoral pulse

Answer: (A)

When assessing an unresponsive adult for CPR, you quickly determine whether there is a heartbeat by feeling for a pulse. The carotid artery in the neck is the best site because it’s a central pulse close to the heart and brain, making it the most reliable indicator of whether circulation is present in an emergency. A radial pulse at the wrist can be absent even when the heart is still beating, and it’s harder to detect quickly during a crisis. The brachial pulse is mainly used in infants, and the femoral pulse is not the most practical for rapid assessment in adults. So, checking the carotid pulse in the neck is the standard approach to guide whether to start chest compressions.
