Answer to Question 1

ANS: D
The volume delivered during pressure-controlled modes varies with changes in set pressure, pa-tient effort, and lung mechanics.

Answer to Question 2

ANS: B
The maximum pressure needed to recruit a given patient's lung is unknown; however, most agree that pressures up to 50 cm H2O are safe with most patients when applied for short (1 to 3 min) periods of time.
