26. Which of the following describes the action of a gravity air displacement sterilizer?

Pressurized steam pushes air out of the sterilizing chamber, and high-pressure steam sterilizes the instruments.
Air is removed from the sterilizing chamber through a vacuum, and steam replaces the air to sterilize the instruments.
Pressurized gas is pushed into the chamber to circulate with high levels of humidity, which sterilizes the instruments.
Instruments are immersed in fluid, followed by humidified air that circulates at extremely high temperatures.

27. What is the purpose of aeration for items undergoing gas sterilization?

To air-dry the materials and make sure they do not contain moisture before use.
To allow for the release of toxic substances from the surface of the instruments.
To replace the gas at the end of the cycle with humidified air, saturating the instruments before drying.
To instill a protective covering over the instruments, rendering them safe to use in the next procedure.

28. Which of the following are important considerations when packaging instrument trays for sterilization?

Put instrument sets together in closed, covered trays.
Instrument sets should be strung in a closed loop for sterilization, since it keeps all items together.
Nesting instruments or basin sets keeps them too close together and prevents adequate sterilization of all surfaces.
All trays should have a worksheet that outlines the number of instruments being sterilized.

29. Which of the following practices can the tech perform to reduce air contamination during the perioperative setting?

Keep doors closed while in the operating suite and avoid excessive movement between rooms.
Perform a room disinfection using a fog technique after the procedure is complete.
