Answer to Question 1

ANS: B
Withholding feeding 4 to 6 hr before extubation and clamping feeding tubes may be prudent.

Answer to Question 2

ANS: B
Myocardial ischemia may occur frequently among ventilator-dependent patients and has been associated with weaning failure. Critical illness polyneuropathy has been cited as a frequent cause of neuromuscular weaning failure among critically ill patients. Unsuspected neuromuscular dis-ease may be an important factor in ventilator dependency. Inability to wean can sometimes be attributed to psychological dependence, poor oxygenation status, or cardiovascular instability (congestive heart failure or ischemia).
