Answer to Question 1

ANS: B
The primary goal of humidification is to maintain normal physiological conditions in the lower airways.

Answer to Question 2

ANS: D
The ISB shifts distally when a person breathes through the mouth rather than the nose; when he or she breathes cold, dry air; when the upper airway is bypassed (breathing through an artificial tracheal airway); or when the minute ventilation is higher than normal.
