28
Common use of chlorine dioxide
Surfaces disinfectant and sterilant
29
Event-related packaging
It is assumed the contents of package will remain sterile indefinitely unless compromised
30
Sterilant
Agent capable of killing all microorganisms
31
Autoclave
Piece of equipment used for sterilizing by moist heat under pressure
32
Biologic indicators
Vials or strips (spore tests) contain harmless bacterial spores used to determine wether sterilizer working
33
Chemical vapor sterilizer
Used for sterilizing by hot formaldehyde vapors under pressure
34
Critical instrument
Used to penetrate soft tissue or bone

36
Noncritical instrument
Come in contact with intact skin only
37
Clean area
Area of sterilization are where everything clean and sterilized are stored

If instruments not processed immediately what is done
Placed in holding solution
46
Methods of precleaning instruments
Hand scrubbing, ultra sonic cleaning, thermal washer and disinfector
47
method of precleaning instruments least desirable
Hand scrubbing
48
Kitchen dishwashers cannot be used to preclean instruments because they are
not FDA approved
49
Rusting of instruments prevented by
Lubrication
50
Instruments are packaged for sterilization to
Maintain sterility
51
Why aren't pins paper clips staples used
