Question 13 MODU03 - Ballast Control Operator

The Correct Answer is A **Why Option A ("Immerse the arm in cold water") is correct:** For a second-degree burn, the immediate priority is to stop the burning process, reduce pain, and limit tissue damage. Immersing the affected area (the arm) in cool, non-iced water is the standard first-aid treatment. The cool temperature rapidly draws heat away from the burn, which minimizes the depth and severity of the injury, reduces swelling, and provides immediate pain relief. **Why the other options are incorrect:** * **B) Apply antiseptic ointment:** While ointments may be used later, applying any substance (especially thick ointments or creams) immediately to a severe burn can trap heat, worsen the injury, and complicate professional medical assessment later. Immediate cooling is the priority. * **C) Scrub the arm thoroughly to prevent infection:** Scrubbing a burn, particularly a second-degree burn where the skin is compromised, would be extremely painful, cause further tissue damage, and significantly increase the risk of infection by tearing delicate, damaged skin. Burns should be cleaned very gently, if at all, during initial first aid. * **D) Drain any blisters:** Blisters form a natural, sterile protective barrier over the damaged tissue. Draining them (popping them) breaks this barrier, increasing the risk of infection and exposing the sensitive underlying tissue to pain and further injury. Blisters should be left intact unless a medical professional advises otherwise.
