Answer to Question 1

ANS: B
Ventilator bundles are evidence-based practices that can significantly reduce the incidence of VAP. Keeping the patient in a semirecumbent position decreases the risk of aspiration. Using NPPV when possible can significantly lower the rate of nosocomial pneumonia. Ventilator cir-cuits should be changed only when they are visibly dirty, and HMEs should be used whenever possible, because most can filter and all can eliminate condensation in the ventilator circuit.

Answer to Question 2

ANS: C
During critical illnesses, particularly in patients with an endotracheal tube and those receiving mechanical ventilation, a dramatic shift occurs in the flora of the oropharyngeal tract to gram-negative bacilli and Staphylococcus aureus.
