Answer to Question 1

ANS: D
Although suctioning is used to aid secretion clearance, it too can cause damage to the airway mucosa and thus impair mucociliary transport. Inadequate humidification can cause inspissation of secretions, mucus plugging, and airway obstruction. High fractional inspired oxygen concen-trations (FiO2) can impair mucociliary clearance, either directly or by causing an acute tracheo-bronchitis.

Answer to Question 2

ANS: B
