Which factor determines the level of bioburden (microbial level) allowed and,
therefore, the microbial controls required for items used in a general
healthcare setting? Answer - The application or use of the item
Which laboratory biosafety level would be used for managing work with an
organism of moderate risk that is native to the local area? Answer - BSL-2
Which microbial control type can be used to completely eliminate all vegetative
bacteria, endospores, fungi, and viruses from an inanimate item? Answer -
Sterilization
Which term describes the area specifically created and maintained for
performing medical procedures that carry risk from contamination? Answer -
Sterile field
Which physical method of control works by removing microorganisms from a
liquid? Answer - Filtration
Which physical method of control is used to denature proteins and alter
membranes of microorganisms to prevent spoilage of milk, apple juice, honey,
, and other ingestible items to reduce microorganism levels? Answer -
Pasteurization
Which technique will ensure that Clostridium botulinum and botulinum toxin
cannot cause foodborne illness? Answer - Boiling foods for at least 10 minutes
prior to eating.
Which method would be used to sterilize an antibiotic solution? Answer -
Membrane filtration
Which chemical treatment would be used before a disinfectant to reach a
soiled surface? Answer - A surfactant
Which class of chemical disinfectant denatures proteins and disrupts
membranes? Answer - Phenolics
Which chemical is commonly used for hand sanitizers and to degerm a site
prior to injections due to its effective destruction of vegetative bacteria by
denaturing proteins and its quick drying properties? Answer - Alcohols
