Answer to Question 1

ANS: C
The cuff leak test is recommended to detect airway obstruction before extubation.

Answer to Question 2

ANS: D
The presence of an artificial airway may increase airway resistance nearly three-fold, although some evidence calls into question the assumption that breathing through an endotracheal tube offers a greater work of breathing than does breathing through a natural airway postextubation. In a study with 14 successfully extubated patients, at the end of a 2-hr spontaneous breathing trial, there was no difference in work of breathing before and after extubation.
