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 chamberExplanation
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.Rate this question:

- A.
Liquid chemical
- B.
Ethylene oxide gas
- C.
Steam under pressure
- D.
Gamma irradiation
Correct Answer
C. Steam under pressureExplanation
Steam under pressure is generally considered to be the most cost-efficient sterilization method for eliminating bioburden on metal surgical instruments within the SPD. This is because steam under pressure is able to penetrate and effectively sterilize complex instruments, including lumens and crevices, ensuring thorough sterilization. Additionally, steam sterilization is a relatively quick process and does not require the use of expensive chemicals or gases.Rate this question:

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 steamExplanation
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.Rate this question:

- B.
A cabinet at 140°F (60°C)
- C.
An open space at room temperature
- D.
An ethylene oxide (EtO) sterilizer/aerator
Correct Answer
C. An open space at room temperatureExplanation
Ambient aeration refers to aeration that takes place in an open space at room temperature. This means that the process of aeration is occurring naturally in a non-enclosed environment at the normal temperature of the surroundings. It does not involve any specific equipment or controlled conditions like the other options mentioned.Rate this question:

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 heatExplanation
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.Rate this question:
