Answer to Question 1

ANS: B
A patient undergoing positive expiratory pressure therapy must be able to generate expiratory flows high enough to maintain expiratory pressure at 10 to 20 cm H2O.

Answer to Question 2

ANS: D
The rationale for the use of positive expiratory pressure therapy is similar to that for the use of continuous positive airway pressure, except that positive expiratory pressure seems to be less cumbersome and more manageable for patients. Expiratory positive airway pressure and intrap-ulmonary percussive ventilation are just as cumbersome as continuous positive airway pressure. Intermittent positive-pressure breathing is lung expansion therapy, not bronchial hygiene therapy.
