Answer to Question 1

ANS: B
A recommended strategy for setting PEEP is to set a level slightly above the lower inflection point with the goal of recruitment and stabilization of dependent alveoli that would otherwise sustain injury from repetitive opening, closing, and reopening during tidal ventilation.

Answer to Question 2

ANS: B
Normal compliance ranges between 60 and 100 ml/cm H2O.
