Answer to Question 1

ANS: C
Positive airway pressure with positive expiratory pressure is indicated to reduce air trapping in patients with asthma or chronic obstructive pulmonary disease. Intrapulmonary percussive venti-lation is a bronchial hygiene therapy only. Intermittent positive-pressure breathing is a lung ex-pansion therapy that should be used only if another lung expansion therapy, such as incentive spirometry, is not appropriate.

Answer to Question 2

ANS: B
Oxygen saturation should improve as atelectasis resolves. Pulse oximetry is an easy, quick, non-invasive, and cheap way of assessing patients undergoing positive airway pressure therapy.
