| Question | Answer |
|---|---|
| what is not a factor for a disinfected | size of object |
| what type of spore is used to test the EO/dry heat sterilizer | bacillus subtilis |
| what type of spore is used to test steam under pressure/autoclaving | bacillus stearothermophilus |
| when are gloves/gowns removed when leaving the OR | before |
| which are cleaned weekly | cabinet shelves |
| agent that kills all micoorganisms except spore-bearing ones | disinfectant |
| method of sterilization w/cobalt 60 | ionizing radiation |
| 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 |

| 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 |
