Surg 101--Chapter 17 (B&K) Flashcards
Degree of microbial load on an item before sterilization.
bioburden
Microbial load attached to a surface in a fluid environment.
biofilm
Process by which chemical or physical agents are used to clean inanimate, concritical surfaces; a specific contact time is not specified.
decontamination
Water that has been processed through synthetic cation-anion resins to remove the positively or negatively charged ions.
deionized water
Chemical or physical process of destroying most forms of pathogenic microorganisms excepts bacterial endospores; used on inanimate objects but not on tissue.
disinfection
The degree of _____ depends primarily on the strength of the agent, the nature of the contamination, and the purpose for the process.
disinfection
Process that destroys all microorganisms except high numbers of bacterial endospores.
high-level disinfection
Process that inactivates vegetative bacteria, including M. tuberculosis, and most fungi and viruses but does not kill bacterial endospores.
intermediate-level disinfection
Process that kills most bacteria, some viruses, and some fungi but does not destroy resistant microorganisms, such as M. tuberculosis or bacterial endospores.
low-level disinfection
The process of evaporating water and creating condensation from the steam that is collected for future uses.
distilled water
Protective capsule that forms inside specific bacterial species encircles and protects the genetic matter to resist destructive forces, such as disinfection or sterilization.
endospore
Heating process kills many pathogenic microorganisms that are found in biosubstances such as milk or wine.
pateurization
The decontamination process renders soiled instruments safe for _____, but not safe for _____.
handling
patient use
A sterile processing certification program accredited by the National Commission for Certifying Agencies (NCCA).
Certification Board of Sterile Processing and Distribution (CBSPD)
CBSPD offers five levels of certification:
- technician
- supervisor
- manager
- surgical instrument processor
- ambulatory surgery
What can be applied to the instruments to prevent debris from drying during transport to the central service area.
enzymatic foam or solution
True or False: All instruments on the table during a surgical procedure require decontamination before processing to the required level of safety for patient use.
True
Decontamination combines _____ or _____ and a physical or chemical microbial process.
mechanical or manual cleaning
Done in the processing department to render the instrumentation safe for handling by CS personnel.
prerinsing, washing, rinsing, and disinfection/sterilizing
Should be worn at all times while using chemical disinfectant agents.
PPE
What is the purpose of prerinsing or presoaking?
To prevent blood and debris from drying on instruments or to soften and remove dried blood and debris.
_____ or _____ instruments with enzymatic solution in the OR can make further processing more efficient.
Prerinsing or presoaking
What is the purpose of manual cleaning?
To remove residual blood and debris before terminal sterilization or high-level disinfection
Personnel in the processing area wear PPE such as:
- caps
- gloves
- waterproof aprons
- face shields
When cleaning instruments manually, fill the washing sink with clean, _____ to which a concorrosive, _____, low-sudsing, free-rinsing detergent has been added.
warm water
neutral pH
An alkaline detergent (pH more than _____) can stain instruments.
8.5
An acidic detergent (pH less than _____) can corrode or pit instruments.
6
What type of detergents are preferred when manually cleaning instruments?
liquid
When manually cleaning instruments by hand, rinse them thoroughly in _____water at the temperature recommended by the manufacturer.
distilled or deionized
Some enzymes can be inactivated by extreme temeratures, the water should not exceed _____ to prevent burns of the skin.
140 F (60 C)
A washer sterilizer requires instruments to be prewashed by hand in germicidal solution at _____ before being placed in the machine.
110 F (43.3 C)
The temperature of the washer-sterilizer ranges from _____ and would cause coagulation and crusting or protein.
250 - 280 F (121 - 138 C)
A cycle in a washer-sterilizer makes the instruments _____ with the bare hands, but does not render the instrument safe for immediate _____.
safe to handle
patient use or sterile storage
