Answer to Question 1

ANS: D
The level of applied PEEP should be set 3-4 cm H2O above the upper inflection point of the de-flation limb of the P-V curve to help maintain an open lung.

Answer to Question 2

ANS: C
An absolute contraindication to PEEP is a tension pneumothorax. PEEP must be used with care in patients with bronchopleural fistulas and elevated intracranial pressures. PEEP also must be used with care in patients with emphysema, because it may increase hyperinflation, which can lead to compression of adjacent capillaries.
