Answer to Question 1

ANS: B
A VD/VT ratio greater than 0.60 is predictive of lack of success at discontinuance of ventilation.

Answer to Question 2

ANS: B
Because of the relationship between alveolar ventilation and PaCO2, the single best index of ef-fective ventilation is measurement of the PaCO2.
