Answer to Question 1

D
Emphysematous lung changes would cause overinflation and be identified by an increased RV/TLC ratio, an increased functional residual capacity (FRC), and increased residual volume (RV).

Answer to Question 2

Patients with 1-antitrypsin deficiency are at risk of developing panlobular emphysema, which primarily affects the lower portions of the lungs.
