Answer to Question 1

C
Patients with cystic fibrosis have thick, tenacious mucus. This can lead to either a partial airway obstruction (and hyperinflation) or total airway obstruction (and atelectasis). Bronchospasm is only occasionally found.

Answer to Question 2

A
A ball-valve effect in the small airways will cause air trapping on exhalation. In other words, air will be inhaled but cannot be fully exhaled. Apnea of prematurity and bronchiectasis are not related to the ball-valve effect.
