central sterile chapter 10 sterilization

Why is it important to leave space between items when loading steam sterilizer carts

to permit air removal from and steam penetration into packs

How often should biological monitoring of the hydrogen peroxide-ozone sterilizer process be performed

at least daily

Which microorganism is used to biologically monitor the hydrogen peroxide-ozone sterilizer

geobacillus stearothermophilus

Which of the following is compatible with hydrogen peroxide-ozone sterilization
A. natural rubber and latex
B. liquids
C. woven textiles
D. stainless steel instruments

D. stainless steel instruments

What are the parameters for low-temperature gas plasma sterilization

time, temperature, and hydrogen peroxide gas plasma

Which of the following should not be sterilized in a low-temperature gas plasma sterilizer
A. single-channel endoscopes
B. gauze sponges
C. cameras
D. light cords

B. gauze sponges

the Association for the Advancement of Medical Instrumentation recommends that rigid sterilization containers be biologically tested before purchase and annually to verify that

the sterilizer is able to sterilize the contents

unless stated by the sterilizer manufacturer, where should the ethylene oxide process challenge pack (biological test pack) be placed

geometric center of the load

when a positive biological indicator demonstrates a sterilization process failure, and the failure is a result of an operator error what should be done

correct the error and reprocess the load

All devices processed by low-temperature gas plasma must be

clean and dry

Which sterilizer requires only a special electrical outlet or installation

low-temperature gas plasma

which microorganism is most resistant to the steam sterilization process

geobacillus stearothermophilus

which sterilization method requires aeration after processing

ethylene oxide

define super-heating of steam

heat added to dry steam in the absence of water

a loaner instrument has been contaminated during the procedure and the OR wants to sterilize it in the immediate-use sterilizer. what's the first step to take

consult the manufacturer's written instructions for approved cleaning and sterilization methods and parameters

you should unload items from the steam sterilizer with

clean hands

when are sterile packs are most vulnerable to contamination

when the packages are still hot

where do you place biological indicators for testing rigid sterilization containers

as recommended by the manufacturer of the container

all loads containing implantable devices should be

monitored with a biological indicator

routine biological testing of steam sterilizers should be performed no less than

weekly

unless otherwise indicated by the biological indicator manufacturer, if a biological test is performed daily, how long is it necessary to incubate
a control biological indicator

once a day and if a new lot number is used

what is the recommended sterilizer setting for the Bowie-Dick

3 1/2 to 4 minutes at 270*F (132*C) dynamic-air-removal

what should be done if a Bowie-Dick test fails the first time

report to the supervisor for further instructions

type (class) 6 indicators are also called

emulating indicators

a Bowie-Dick test is considered which type of monitoring process

chemical

what is the correct action to take if an item needs to be corrected or removed from the sterilization load record

draw a line through the item and initial

a type (class) 5 indicator is called a(n)

integrating indicator

which monitoring method verifies the conditions within the load were adequate to kill bacterial spores

biological

one reason for adding chemicals to the boiler waterfeed is to

minimize contaminates

what is used to detect air leaks or insufficient air removal(vacuum)

Bowie-Dick test

stacking of rigid sterilization containers in a steam sterilizer is permitted when

the manufacturer of the container provides technical data showing that it is acceptable

how should basin sets be positioned for steam sterilization

tilted on their sides

where should textile packs be placed in a mixed load of textile and metal goods

on the top rack

if packages are moist at the end of the steam cycle what can occur

microorganisms can wick into the package causing possible contamination

for steam sterilization to occur steam must

make direct contact with all surfaces

which best describes a "wet load"
A. wet sets placed inside the sterilizer
B. a single package with moisture droplets
C. multiple packages in the same load found with excess moisture
D. excess moisture collecting in the drain line

C. multiple packages in the same load found with excess moisture

when might immediate-use steam sterilization be indicated

when a one-of-a-kind instrument is contaminated

what is the minimum exposure time for wrapped goods in a dynamic-air-removal steam cycle at 275*F (135*C) and 28 to 30 pounds per square inch (psi)

3 minutes

in a non-tabletop sterilizer, what does the gauge on the main steam line (usually located on the back of the sterilizer) tell you

the steam pressure as steam enters the jacket

define sterilization

the process by which all forms of microbial life, including spore, are destroyed
