C. Incorrect response: See explanation D.
D. Correct response: Certain processes-of-care characteristics may contribute to lowering the risk of PMV. These include tight glycemic control in surgical patients, screening for and performance of spontaneous breathing trials, and the use of low tidal volumes among ALI patients.

Answer to Question 2

ANS: C
A. Incorrect response: See explanation C.
B. Incorrect response: See explanation C.
C. Correct response: An important factor in the development of PMV is critical illness polyneuropathy. Using neuromuscular blocking agents and high-dose corticosteroids are two risk factors for polyneuropathy that need to be limited to conditions in which they are absolutely indicated.
