Which action checks for a P (Pain) response?

• A. Pinch the earlobe to check pain response
• B. Squeeze the toe over the toenail
• C. Rub the breastbone briskly with a knuckle
• D. Shake the casualty to elicit a response

Answer: (C)

Testing for a Pain response means applying a quick, noxious stimulus to see if the casualty reacts. Briskly rubbing the breastbone with a knuckle provides a strong, centralized painful stimulus that is fast to provoke a response and easy to perform safely. This method is reliable and widely taught for assessing responsiveness because it tends to elicit a reaction if the person is at least minimally conscious. Other options either deliver pain in a less consistent way or carry more risk or uncertainty—pinching the earlobe or squeezing the toe over the nail can be inconsistent and potentially cause tissue injury, and shaking the casualty is not a pain stimulus and may not reliably indicate a true pain response.
