Answer to Question 1

ANS: A
When excessive PEEP is used, blood flow is diverted from ventilated alveoli to hypoventilated alveoli; the result is an increased ratio.

Answer to Question 2

ANS: D
If compliance or resistance decreases, the time constant for a given lung unit decreases, and the lung fills and empties faster.
