Answer to Question 1

ANS: B
Items need to be clean, free of grease and oil, and not sensitive to heat. Precautions must be used in using the sterilizer and drying the load. Impurities can cause wet or stained packs and stained instruments.

Answer to Question 2

ANS: A
Aeration is the cycle to vent the chamber of airborne residual gas. Some chambers are a combination sterilizer/aerator, which eliminates the need for personnel to handle the load immediately after sterilization. The load is removed only after aeration. The aerator is vented to the outside atmosphere.
