After giving immediate first aid, what is the correct next step for any seafarer, regardless of rank, dealing with an injured colleague?

A. Continue treating the casualty alone for as long as possible before telling anyone else, to avoid causing unnecessary alarm

B. Wait until the next scheduled watch handover to report the incident through normal channels

C. Alert the bridge/officer of the watch or designated medical person immediately, give a clear, calm description of what happened and what you have observed and done, and continue to monitor the casualty until more qualified help arrives

D. Only inform someone once you are completely certain of exactly what is medically wrong

A. Immediately start chest compressions regardless of the situation

B. Check their pockets for ID and medical information first

C. Danger (is the scene safe for you to approach?), Response (are they conscious — talk and gently shake), Airway, Breathing, Circulation — the standard DRABC primary survey

D. Call the bridge before checking the casualty at all

A. Wash the wound thoroughly with soap and water before applying any pressure

B. Apply a tourniquet immediately as the first response to any heavy bleeding

C. Leave the wound uncovered to let air help it clot naturally

D. Apply firm, direct pressure to the wound with a clean dressing or cloth, and maintain it continuously — elevate the limb above heart level if possible and there is no suspected fracture
