Answer to Question 1

ANS: C
In COPD, patients commonly develop a barrel-shaped chest due to emphysematous changes in the lungs. A barrel shape is due to an increased anterior-posterior (AP) diameter. In emphysema, there is a 1:1 ratio of AP to lateral diameter; AP diameter equals the lateral diameter. Normally the AP diameter is twice the lateral diameter.

Answer to Question 2

ANS: A
For pulmonary malignancy, chest films are often nondiagnostic, although they may reveal a nodule, mass, or other abnormality. A CT scan of the chest is typically diagnostic.
