What should be done to instruments with a working bar, such as scissors, prior to sterilization?
Scissors should be lubricated and ratchets should be checked to ensure they are working properly.
What is the recommended storage time for autoclaved items?
Autoclaved items should be stored for 1 year.
What is the purpose of covering sharp ends and wrapping surgical kits in a water resistant shroud?
To protect healthcare workers from injury and prevent contamination of the surgical kits.
Which method of sterilization is commonly used for large scale practices using endoscopes?

What is the purpose of pasteurization in the food industry?
To kill microorganisms
What are the advantages of using an autoclave for sterilization?
More effective destruction of all microorganisms and spores
What is the difference between heat sterilization and chemical sterilization?
Heat alone is only partially effective against all pathogens, while chemical sterilization is more effective

To remove moisture from sterilized items
What is the recommended temperature and time for sterilization in an autoclave?
134 degrees Celsius for 3.5 minutes
What is the purpose of a drying system in the sterilization process?
The purpose of a drying system is to remove moisture from the sterilized surgical kits.
How should surgical implements be prepared for sterilization?
Surgical implements should be clean, free from gross contamination, and regularly checked for damage.
What are some methods for monitoring the effectiveness of sterilization?
Some methods for monitoring sterilization include using bowie dick tape, TST strips, and checking for black lines or indicators of sterilization.
How should sterile supplies be labeled and stored?
Sterile supplies should be labeled, dated, and initialed. Storage is recommended for 1 year for autoclaved items or 2 years for gas sterilized items.

What is the purpose of pasteurization?
The purpose of pasteurization is to kill microorganisms in the food industry.
What temperature is needed for pasteurization to effectively kill microorganisms?
Pasteurization needs to go above 140 degrees to kill microorganisms.
Why is pasteurization not effective against spore creating bacteria?
Pasteurization is not effective against spore creating bacteria because it does not reach the necessary temperature and pressure to kill them.
What is the main advantage of sterilization using steam?
The main advantage of sterilization using steam is that it effectively destroys all microorganisms and spores.
What is the recommended temperature and time for sterilization in an autoclave?
The recommended temperatures for sterilization in an autoclave are 121 degrees for 15 minutes and 134 degrees for 3.5 minutes.
