Answer to Question 1

ANS: C
Gas exchange is impaired owing to ventilation/perfusion mismatching, shunt, and decreased dif-fusion across the abnormal interstitium.

Answer to Question 2

ANS: A
Mr. Jones' medical history suggests chronic bronchitis exacerbated by a respiratory infection such as acute bronchitis, flu, or pneumonia. Chronic bronchitis is defined in clinical terms as a condi-tion in which chronic productive cough is present for at least 3 months per year for at least 2 consecutive years.
