Answer to Question 1

ANS: D
Reduced compliance results in lower volumes during pressure-controlled continuous mandatory ventilation (PC-CMV).

Answer to Question 2

ANS: C
In many cases, clinicians prefer using noninvasive positive pressure ventilator support in the form of bilevel positive airway pressure (bilevel PAP) rather than CPAP for patients with Raw-induced auto-PEEP. Bilevel PAP also is the method most often used to treat acute-on-chronic respiratory failure.
