In the check phase, which action is performed to assess the casualty?

• A. Determine unconsciousness
• B. Shout for help
• C. Notify passengers
• D. Evacuate

Answer: (A)

The check phase is about quickly gauging the casualty’s state by determining whether they are conscious or unconscious. You test responsiveness—speak to them, gently tap their shoulder, or ask a simple question to see if they can respond. If they respond, you know they are conscious and you can continue with the next steps of care. If there’s no response, treat the casualty as unconscious and proceed to summon emergency help and start appropriate life-saving measures.

Shouting for help can be part of getting assistance, but the essential action in the check phase to assess the casualty is determining consciousness. Notifying others to evacuate or to inform passengers aren’t part of the immediate assessment of the casualty’s condition.
