Answer to Question 1

ANS: D
Diseases that alter normal mucociliary clearance can also cause secretion retention. CF is a com-mon disorder in this category. In CF, the solute concentration of the mucus is altered because of abnormal sodium and chloride transport. This increases mucus viscosity and impairs its movement up the respiratory tract. Although less common, there are several conditions in which the respira-tory tract cilia do not function properly. These ciliary dyskinetic syndromes also can contribute to ineffective airway clearance.

Answer to Question 2

ANS: C

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition.
