Correct answer: E — Silicosis from respirable crystalline silica exposure

Upper-zone nodularity, restrictive physiology and prolonged respirable crystalline silica exposure support silicosis. Dry sweeping suggests poor exposure control and potential exposure above safe levels. The worker needs respiratory referral, exposure cessation or control, and consideration of surveillance for co-workers.
