How can a skipper obtain medical advice for a crew member in distress at sea when no medical professional is aboard?

A. Ask on the local marina channel and hope a doctor is monitoring

B. Medical advice at sea is not available — manage alone until port

C. Transmit a Pan Pan on Ch 16 to HM Coastguard and request relay to the duty doctor at the Maritime and Coastguard Agency's medical advisory service (or CIRM/equivalent internationally)

D. Call 999 on a mobile phone — UK emergency services will always have maritime coverage

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
