Answer to Question 1

ANS: C
If the door is left open, the positive air pressure in the room equalizes with the negative air pressure in the hallway. The disrupted pressurization mixes the clean air of the OR with air in the hallway, which has a higher microbial count.

Answer to Question 2

ANS: C
Fomites are contaminated particles present in dust that settle on inanimate objects. OR surfaces must be disinfected promptly and dust covers kept over sterile supplies to prevent the settling of dust on the packages.
