Answer to Question 1

ANS: B
A. Incorrect response: The peak inspiratory pressure will increase in the presence of auto-PEEP during volume-targeted ventilation.
B. Correct response: The tidal volume will be reduced in the presence of auto-PEEP during pressure-targeted ventilation.
C. Incorrect response: Auto-PEEP will not affect the flow-termination criterion.
D. Incorrect response: The inspiratory time is not affected by auto-PEEP.

Answer to Question 2

A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: In a normal person, gravitational effects on lung water and required stretch make airway resistance slightly higher in the bases than in other regions of the lungs.
