Which diving-related condition can occur after rapid ascent and involves symptoms such as joint pain and dizziness?

• A. Air Embolism
• B. Decompression Sickness
• C. Nitrogen Narcosis
• D. Oxygen Toxicity

Answer: (B)

During a dive, rapid ascent lowers the ambient pressure quickly, causing dissolved nitrogen in the body to come out of solution and form bubbles in tissues and the bloodstream. These bubbles can irritate joints and nerves and disrupt blood flow, leading to symptoms like joint pain (the bends) and dizziness as the bubbles affect the musculoskeletal, nervous, and circulatory systems. This pattern fits the scenario best because the problem emerges after ascending too quickly and presents with those specific symptoms. Air embolism would arise from lung barotrauma and typically presents with chest pain, shortness of breath, coughing, or sudden neurological changes from air entering the circulation—not the classic joint pains. Nitrogen narcosis is a depth-related cognitive effect that happens while still under pressure, not after ascent. Oxygen toxicity involves high oxygen levels causing seizures or other CNS or pulmonary symptoms, again not the described joint pain and dizziness after surfacing.
