Answer to Question 1

ANS: C
The most likely cause of chronic bronchitis is cigarette smoke. Chronic bronchitis in such a pa-tient is not commonly associated with chronic asthma. Air pollution and recurrent infections may contribute, but smoking is the most common cause.

Answer to Question 2

ANS: A
Air trapping, not increased flow rates, expands the thorax, putting the respiratory muscles at a mechanical disadvantage. Neither decreased inspiratory reserve volumes nor alveolar destruction is associated with an increased anterior-posterior chest diameter.
