Which of the following describes skin manifestations of decompression sickness?

• A. A mottled, reddish or purplish rash and bubbles in the skin
• B. Severe headache and nausea
• C. Sudden onset of chest pain and difficulty breathing
• D. Fatigue and muscle cramps

Answer: (A)

The skin manifestations of decompression sickness, often referred to as "the bends," are characterized by a mottled, reddish or purplish rash accompanied by bubbles in the skin. This occurs due to nitrogen gas that has come out of solution in the body tissues and formed bubbles, leading to the observed skin changes. The rash and bubbles represent the body's inflammatory response to the presence of these bubbles, which can cut off blood flow and cause pain or discomfort. The presence of these skin signs can be a key indicator that a person is experiencing decompression sickness, warranting immediate medical attention. The other options describe symptoms that are associated with decompression sickness but do not specifically refer to skin manifestations. Severe headache and nausea are more systemic symptoms that occur due to a variety of factors, including increased pressure on the nervous system. Sudden onset of chest pain and difficulty breathing may indicate more critical complications related to decompression, such as an air embolism but not specifically the skin manifestations. Fatigue and muscle cramps are general symptoms that may arise from various conditions and are not distinct indicators of the skin effects linked to decompression sickness. Hence, option A accurately captures the distinctive skin-related symptoms associated with this condition.
