Aspiration can lead to

• A. Bronchitis
• B. Pneumonia
• C. Emphysema
• D. Atelectasis

Answer: (B)

Aspiration brings material from the mouth or stomach into the lungs, and in older adults with swallowing difficulties that material can irritate lung tissue and become a breeding ground for infection. The inflammatory and infectious response this triggers most commonly develops into pneumonia, making it the best answer.

Bronchitis is inflammation of the airways and can occur with irritation, but it is not the typical infectious consequence of aspiration. Emphysema is a chronic lung disease usually linked to smoking or genetic factors, not a direct result of aspiration. Atelectasis, a collapse of part of the lung, can happen if an airway is blocked or breathing is very shallow after aspiration, but pneumonia is the more characteristic and clinically significant outcome.
