A crew member is injured in an engine room walkway, blocking an escape route others need in an emergency. When is it appropriate to move them before help arrives?

A. Always move any casualty immediately regardless of injury, since blocking a walkway is itself dangerous

B. Only the ship's designated medic is permitted to make any decision about moving a casualty

C. Never move a casualty under any circumstances, even if there is a fire spreading towards them

D. Generally avoid moving a casualty with a suspected back, neck, or head injury unless there is an immediate danger (fire, flooding, toxic atmosphere) that makes staying in place more dangerous than moving them — if movement is essential, support the head and neck and move as a coordinated team, not by one person alone

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
