Asepsis and Sterile Technique Flashcards
Indigenous microflora
Microbes that live on the skin and in the human body
Opportunistic Pathogens
Indigenous flora that’s harmless but given the opportunity that become harmful
Both organisms benefit from and depend on one another to a certain extent
Mutualism
Type of mutualism where two organisms work together to achieve a goal neither could achieve on their own
Synergism
One organism benefits while the other neither benefits or harms
Commensalism
One organism benefits and the host is harmed
Parasitism
Microorganisms that cause infection
Pathogens
Nosocomial Infections
Infections acquired in the hospital
What are prokaryotes
Bacteria (Non-membraneous)
Non-living organisms that are completely reliant on their host
Viruses
Made of protons that attack the brain
Prions
Creutzfeldt-Jakob disease (CJD)
Prion disease that attacks the brain
Resident Flora
Microbes that reside under the skin or within the body
Substance used on living tissue to inhibit the growth and reproduction of microbes
Antiseptic
Bacteriocidal
Substance that kills/destroys bacteria
Bacteriostatic
Inhibits the growth of bacteria
Bioburden
The number of microbes or amount of organic debris on an object
Decontamination
To reduce to an irreducible amount of pathogenic material
Disinfectant
Chemical agent that kills most microbes (inanimate Objects) Doesn’t kill spores
Fomite
Inanimate object that harbors microorganisms
Fungicide
Destroys fungi
Nosocomial
Infection inquired within an healthcare facility
Pathogen
Any microbe capable of causing disease
Sepsis
Infection, accompanied by fever, caused by pathogen
Spore
A resistant form of certain types of bacteria that are able to survive in adverse conditions
Sterile
Rendered free of all microorganisms, including spores
Sterilization
Destruction of all microorganisms, including spores on inanimate objects and surfaces
Strike-through contamination
Contamination of a sterile field that occurs through the passage of fluid through or a puncture in a microbial barrier
Surgically Clean
Mechanically clean and chemically disinfected but not sterile
Transient Flora
Microbes that reside on the skin surface and are easily removed
Vector
Living carrier that transmits disease
Virucide
Agent that destroys viruses
Used on tissue
Antiseptic
Used on inanimate objects
Decontaminate, Disinfectant
Where on the inside of a paper wrap is it unsterile
The 1 inch boarder around the edge
What distance should a non sterile individual keep with a sterile field
12inches
Critical items (for sterilization)
Must be sterile prior to use on tissue or within the body
Semi critical items (for sterilization)
Items that come in contact with microorganisms but no body cavities (Cystoscopes, Colonscopes, Laryngoscopes) Mucous membranes are resistant to spores so items only need to be disinfected
Noncritical items
Come in contact with the skin but don’t puncture the skin or come in contact with any mucous membrane (Blood pressure cuffs, OR furniture, OR Table)
When is terminal cleaning done
At the end of each day
How often are cabinets and supply rooms cleaned
Once a week
Minimum air exchange rate
10 times per hour
OR temp
Btw 64-70 degrees
Humidity
35%-72%
What type of air pressure is maintained
Negative
What temp is a gravity displacement sterilizer placed at
250-270 degrees (15-17 psi)
Removes particles that mechanical and sterilizer couldn’t reach
Ultrasonic cleaner
Flash Sterilizer time
3-4minutes (270degrees)
biological indicator for steam sterilizer
Bacillus stearothermopphilus
