Answer to Question 1

ANS: C
The information indicates that the patient has ventilator-associated pneumonia; ventila-tor-associated pneumonia must be suspected anytime intubation develops shortly after endotra-cheal intubation. There are many actions that can be taken to prevent its development. Current standards state that the ventilator circuit should be changed only when it is grossly contaminated.

Answer to Question 2

ANS: B
Acetic acid is the agent of choice to disinfect home care equipment due to its low cost and effec-tiveness. Alkaline glutaraldehyde requires a use of a hood for protection from fumes. Pasteuriza-tion and autoclave both require specialized equipment.
