to change the vital functions,forces & activities of an organ | denaturation |
agent that kill bacteria | bacteriocidal |
agent that inhibts the growth of micoorganisms on animate surfaces | antiseptic |
all affect sterilization process except | type of sterilizing agent |
uses agitated water w/detergent to loosen soil, then steam displaces the water and items are sterilized at 132 c or 270 f | washer-sterilizer |
is a smaller version sterililzer, can reach higher temps w/reduced exposure time | high speed (flash) gravity sterilizer |
unwrapped metal instruments are sterilized at | 132 c (270 f), 3 minutes minimum, at 27 PSI |
unwrapped metal instruments combined w/porus materials are sterilized at | 132 c (270 f), 10 minutes minimum, at 27 PSI |
wrapped instruments,packs,bulk loads are sterilized at | 121 c (250 f), 30 minutes minimum, at 15 PDS |
a steam sterilizer is how hot | 250 f |
EO sterilization is not dependent on | gravity |
what type of sterilization is perferred for air powered instruments | EO |
what is not used as an antiseptic | glutaraldehyde |
how long does activated glutaraldehyde require in total immersion for disinfection | 10 minutes |
instruments must be rinsed how many times w/sterile distilled water | at least 2 times |
what is not a method of the sterilization process | physical |
which is a method of the sterilization process | chemical |
used primarily for oils,petroleum & bulk powders | hot air/dry heat |
when preparing items for sterilization how should the lock boxes be positioned | opened |
when preparing items for sterilization all detachable parts s/be | disassembled |

what is not used in the OR to clean | glutaraldehyde |
anesthesia equipment is changed when | after each pt |
how often s/steam sterlizers be cleaned | weekly |
what role does humidity play in the EO | hydrate spores |
what is not a form of sterilization | boiling water |
EO kills microorganism by | denaturation & chemical interference |
all are manual method except | instruments are placed into the washer-sterilizer |
when s/the OR table be wiped down | after each pt |
