A crew member is found unresponsive and not breathing normally. What is the correct CPR technique once you have confirmed this and called for help?

A. Rescue breaths only, with chest compressions reserved for medically trained crew

B. Chest compressions and rescue breaths in a 30:2 ratio, compressions at a rate of 100-120 per minute, pressing to a depth of 5-6cm and allowing full chest recoil between compressions

C. Continuous chest compressions with no breaks for breaths under any circumstances

D. 15 compressions to 1 breath, repeated continuously

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
