A crew member has a 3cm clean laceration on the forearm from a winch handle. It is gaping but not deep. No medical professional is available. What is the best closure method from a well-stocked first aid kit?

A. Leave open — all wounds at sea should be left to drain due to infection risk

B. Clean and irrigate with saline or clean water; close with steri-strips (butterfly closures) or wound closure strips applied perpendicular to the wound edges; cover with a non-adherent dressing; keep dry; seek medical review within 6 hours if possible

C. Use sutures from the medical kit — suturing is a basic seamanship skill all skippers should know

D. Apply superglue to seal the wound immediately without cleaning

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
