Is the item reusable or disposable? Is it safe? Is sterilization needed? Will it penetrate effectively? Can it withstand physical or chemical treatments? Is it cost and labor-efficient?

Which of the following should be considered when initially choosing a method of microbial control?

blank 1 : sterilization blank 2 : disinfection

_________ is the destruction of all microbial life - whereas what destroys most microbial life, thus reducing contamination on inanimate surfaces

sterilization

a process that completely removes or destroys all viable microorganisms, including viruses, from an object or habitat that is referred to as

true

a sporicide agent can also be sterilant because it can destroy bacterial endospores and leave an object free of all life

all viable microorganisms and viruses

a sterile object is free of

sporicidal

agent can also be a sterilant because it can destroy bacterial endospores and leave an object free of all life

uniform populations of like microbes

all of the following describe the typical microbial population targeted by antimicrobial drugs EXCEPT

chemical

antiseptics are what type of agents applied to the skin to inhibit vegetative bacterial cells

bacteriostatic

any process or agent that inhibits bacterial growth is referred to as what

antiseptics

chemical agents applied directly to body surfaces to inhibit vegetative pathogens

blank 1 : human blank 2 : animal

disinfectants are normally used only on inanimate objects because they can be toxic or harmful to __________ and other __________ tissues

only vegetative bacterial cells

disinfection destroys

sanitization

is a decontamination technique that mechanically removes microorganisms and debris from inanimate objects to reduce contamination to safe levels

degermation

is the physical removal of surface oils, debris and soil from skin to reduce the microbial load

generally reserved for inanimate objects only necessary for certain groups of microbes

sterilization is

is highly dangerous and impractical

sterilization of the skin

asepsis

term referring to a condition free of pathogenic microorganism or a procedure or process designed to prevent entry of infectious agents
