Answer to Question 1

ANS: A
A. Correct response: Spontaneous breaths during airway pressure release ventilation (APRV) are flow or pressure triggered, pressure cycled (CPAP), or flow cycled (PSV).
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.

Answer to Question 2

ANS: A
A. Correct response: Performing an inspiratory pause maneuver increases the mean airway pressure, and lengthens gas exchange time. If the resultant expiratory time is inadequate for the lung to return to its normal end-expiratory volume, auto-PEEP develops.
B. Incorrect response: See explanation A.
C. Incorrect response: See explanation A.
D. Incorrect response: See explanation A.
