  2. Bleeding, Shock and IV Fluids

    How to recognise and control bleeding on board (pressure, dressings, tourniquets, neck wounds, amputations), and how to spot and manage shock: circulation checks, haemorrhagic shock classes, IV fluids and drip-rate maths. With no doctor on board, these skills keep a trauma casualty alive until evacuation, and they are core MCA medical care exam material.

  3. Bridge Equipment: SOLAS V/19 Carriage Requirements

    What SOLAS V/19 makes a ship carry on the bridge, step by step from all ships up to 50,000 GT, and how the OOW checks and uses each item: compasses, GNSS, logs, echo sounder, ECDIS, AIS, BNWAS and steering gear. "What must a 500 GT yacht carry?" is a classic MCA oral question.

  4. Burns: Assessment, First Aid and Dressing

    How to assess a burn on board (depth, size by the rule of nines, chemical, electrical and inhalation burns), stop the burning and cool it, dress it, and replace lost fluid with the Parkland formula. With no doctor on board, these steps limit shock, infection and scarring, and they are core MCA medical care exam material.

  5. Cardinal Marks

    The four IALA cardinal marks — North, East, South and West: what they tell you, their topmarks, colours and white lights, and how to pass them. Reading them fast keeps the ship on the safe side of a danger, and they are a standard MCA oral question.
