A crew member falls and is suspected of having a fractured wrist. There is no AED or trained medic on board. What is the correct approach?

A. Straighten the limb to its normal position and bandage tightly

B. Immobilise the limb in the position found using a splint and padding; apply ice pack if available to reduce swelling; support in a sling; give appropriate pain relief if available and permitted; seek medical advice via Ch 16

C. Do nothing — fractures at sea always resolve without treatment

D. Apply a tight tourniquet to prevent swelling spreading

A. Severe hypothermia — perform CPR immediately regardless of pulse

B. Heat exhaustion — cool the casualty and give cold water

C. Mild to moderate hypothermia (core temp ~32–35°C) — remove wet clothing, insulate from wind and cold, warm with blankets and foil, give warm sweet drinks if conscious and no injury suspected, handle gently and do NOT rub limbs

D. Mild hypothermia — exercise to generate body heat

A. Start rescue breaths (5 initial breaths) immediately, then begin standard CPR (30 compressions : 2 breaths) — airway and breathing take priority as drowning is a hypoxic event

B. Place in recovery position and monitor — never start CPR on a drowning victim who may vomit

C. Clear the airway by holding the casualty upside down first

D. Start chest compressions only — do not give rescue breaths
