(20) principles and techniques of disinfection Flashcards
antiseptic
Substance for killing microorganisms on the skin
bioburden
Blood, saliva, and other body fluids
broad-spectrum activity
Capable of killing a wide range of microbes
chlorine dioxide
Effective, rapid-acting environmental surface disinfectant or chemical sterilant
clinical contact surface
Surface touched by contaminated hands, instruments, or spatter during dental treatment
disinfectant
Chemical used to reduce or lower the number of microorganisms on inanimate objects
environmental surface
Surface within a healthcare facility that is not directly involved in patient care, but that may become contaminated during the course of treatment
fungicidal
A product that is capable of killing fungi
glutaraldehyde
Environmental Protection Agency (EPA)-registered high-level disinfectant.
greener infection control
Minimizing the environmental impact of infection control products and procedures
high level disinfectant
Hospital disinfectant with tuberculocidal activity
hospital disinfectant
Disinfectant with the ability to kill staphylococcus aureus, salmonella choleraesuis, and pseudomonas aeruginosa
housekeeping surface
Surface that is not contaminated during dental treatment
immersion disinfectant
Disinfectant used for immersion (soaking) of heat-sensitive instruments
intermediate level disinfectant
Liquid disinfectant with EPA registration as a hospital disinfectant with tuberculocidal activity. It is used for disinfecting operatory surfaces.
iodophor
EPA-registered, intermediate-level hospital disinfectant
liquid sterilant
Chemical used at room temperature for items that are damaged by heat sterilization
low-level disinfectant
Disinfectant that destroys certain viruses and fungi; used for general housecleaning
precleaning
Removal of bioburden before disinfection
residual activity
Action that continues long after initial application, as with disinfectants
reuse life
Time period that a disinfectant should remain effective during use and reuse
shelf life
How long a product may be stored before use.
single use items
Items that are used on only one patient and then are thrown away
sodium hypochlorite
Surface disinfectant commonly known as household bleach
splash, splatter, droplet surface
Surface that does not contact members of the dental team or contaminated instruments or supplies
sporicidal
Capable of killing bacterial spores
streilization
The process of destroying all microbes
surface barrier
Fluid resistant material used to cover surfaces likely to become contaminated
synthetic phenol compound
EPA-registered intermediate-level hospital disinfectant with broad-spectrum disinfecting action
touch surface
Surface directly touched and contaminated during procedures
transfer surface
Surface not directly touched but often contacted by contaminated instruments
tuberculocidal
Capable of inactivating tuberculosis causing microorganisms
virucidal
Capable of killing some viruses
