Drains in pre-vacuum and gravity-displacement sterilizers are placed at the bottom front of the strilizers
A.
To make it easy to service the sterilizers
B.
To make it easy to monitor the steam pressure in the sterilizer
C.
Because national plumbing codes dictate placement
D.
Because the air tends to concentrate at the bottom of the chamber
Correct Answer
D. Because the air tends to concentrate at the bottom of the chamber
Explanation Drains in pre-vacuum and gravity-displacement sterilizers are placed at the bottom front of the sterilizers because the air tends to concentrate at the bottom of the chamber. This placement allows for the efficient removal of air from the sterilizer during the sterilization process. By placing the drains at the bottom front, any trapped air can easily be released, ensuring that the sterilization process is effective and thorough.

When heat is added to steam without increasing the moisture content, the steam is called
A.
Wet steam
B.
Assimilated steam
C.
Steam under pressure
D.
Superheated steam
Correct Answer
D. Superheated steam
Explanation When heat is added to steam without increasing the moisture content, the steam becomes superheated. Superheated steam is steam that is heated to a temperature higher than its boiling point at a given pressure. This process removes any remaining moisture from the steam, resulting in a dry and high-temperature steam. Superheated steam is often used in various industrial processes where high temperatures are required.

Which of the following sterilization methods would be appropriate for petrolatum gauze dressings?
A.
Steam
B.
Ethylene Oxide
C.
Dry heat
D.
Peracetic acid
Correct Answer
C. Dry heat
Explanation Dry heat sterilization would be appropriate for petrolatum gauze dressings because it is a method that uses high temperatures to kill microorganisms. Petrolatum gauze dressings are typically made of a non-woven fabric impregnated with petrolatum, which is a flammable substance. Using steam or ethylene oxide sterilization methods could potentially cause damage or alteration to the dressing due to the presence of moisture or chemical reactions. Peracetic acid sterilization is more commonly used for heat-sensitive medical devices and instruments, rather than dressings. Therefore, dry heat sterilization is the most suitable method for ensuring the sterility of petrolatum gauze dressings.
