Answer to Question 1

ANS: D
Increased compliance results primarily from loss of elastic fibers, which occurs in emphysema.

Answer to Question 2

ANS: B
The compliance curve of the patient with pulmonary fibrosis is flatter than the normal curve, shifted down and to the right. As a result, there is a smaller volume changes for any given pres-sure change (decreased compliance).
