Answer to Question 1

ANS: A
An early randomized controlled trial of IV methylprednisolone for patients with acute exacerba-tions has shown accelerated improvement in FEV1 within 72 hr.

Answer to Question 2

ANS: D
Criteria defining candidacy for noninvasive ventilation include acute respiratory acidosis (with-out frank respiratory arrest), hemodynamic stability, ability to tolerate the interface needed for noninvasive ventilation, ability to protect the airway, and lack of craniofacial trauma or burns, copious secretions, or massive obesity.
