Answer to Question 1

ANS: C
The Puritan Bennett AP-4 is only patient-triggered, so it can be used for intermittent posi-tive-pressure breathing therapy but not for providing short-term ventilatory support of patients with apnea. The other ventilators mentioned are able to support patients for short-term mechani-cal ventilation.

Answer to Question 2

ANS: D
The patient's ability to ventilate and cough effectively is compromised because she is not alert. Because of this, incentive spirometry, deep-breathing exercises, and positive expiratory pressure are not appropriate therapies. Intermittent positive-pressure breathing is appropriate because she is not alert.
