• A. What are two common signs of decompression sickness that may occur during ascent or after landing?
• B. Chest pain and fever.
• C. Rash and itching only.
• D. Cough and wheeze.

Answer: (A)

Decompression sickness arises when dissolved nitrogen forms bubbles as you ascend, disrupting tissue and blood flow. The most reliable signals during ascent or after landing involve the skin and joints. Bubbles in joints cause the characteristic pain of the bends, while bubbles in the skin and subcutaneous tissues can produce itching and a patchy, mottled rash. Chest pain or cough can occur if the lungs are involved, but fever is not a typical sign of DCS. Therefore, rash with itching best reflects common cutaneous signs of decompression sickness, making it the most consistent choice among the options. Remember that joint pain is also a key feature, so overall recognition includes both joint discomfort and skin symptoms when DCS is suspected.
