Which body characteristic is associated with rapid decompression?

• A. Ear discomfort
• B. Nosebleed
• C. Hot sensation
• D. Sudden weight loss

Answer: (A)

Rapid decompression creates a sudden drop in ambient pressure that the air inside the body must escape from or equalize with. The middle ear, connected to the throat by the Eustachian tube, is one of the first spaces affected. If the tube can’t open enough to vent the pressure quickly, a pressure difference across the tympanic membrane develops, causing pain, fullness, and general ear discomfort. That ear-related sensation is the most immediate and characteristic effect in this situation, making it the best answer. Nosebleeds aren’t a typical immediate sign of rapid decompression, though nasal passages can dry out or be irritated for other reasons. A hot sensation or sudden weight loss don’t reflect the immediate physiological response to a rapid drop in cabin pressure.
