Chapter 8: Sterilization

Front 1

The process which all forms pf microbial life, including spores, are destroyed

sterilization

Front 2

A gauge on the main steam line, usually located at the back of the sterilizer, tells you the steam pressure

as it is entering the jacket

Front 3

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

3 minutes

Front 4

Immediate-use steam sterilization may be indicated when

Back 4

a one-of-a-kind instrument is contaminated

Front 5

Best describes a "wet load"

Back 5

multiple packages in the same load found with excess moisture

Front 6

For sterilization to occur, steam MUST

Back 6

make direct contact with all surfaces

Front 7

This action should be taken if a sterilized load is determined to be wet

Back 7

reprocess the entire load

Front 8

Can occur if packages are moist at the end of the steam cycle

Back 8

microorganisms can wick into the package

Front 9

For sterilization, paper-plastic peel packages should be placed

Back 9

on their edge

Front 10

In a mixed load of textile and metal goods, the textile packs should be placed

Back 10

on the top rack

Front 11

For steam sterilization, basin sets should be positioned

Back 11

tilted on their sides

Front 12

Stacking of rigid containers in a steam sterilizer is permitted when

Back 12

the manufacturer provides technical data showing that it is acceptable

Front 13

Is used to detect air leaks or insufficient air removal

Back 13

Bowie-Dick test

Front 14

One reason for adding chemicals to the boiler feed-water is to

Back 14

minimize contaminates

Front 15

Which monitoring method verifies that conditions within the load were adequate to kill bacterial spore

Back 15

biological

Front 16

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

Back 16

draw a line through the item and initial

Front 17

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

Back 17

chemical

Front 18

A class 5 indicator is called a

Back 18

integrating indicator

Front 19

Class 6 indicators are also called

Back 19

emulating indicators

Front 20

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

Back 20

report to the supervisor for further instruction

Front 21

Is the RECOMMENDED sterilizer setting for the Bowie-Dick test

Back 21

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

Front 22

Generally, if a biological test is performed daily, how often is it necessary to incubate a control biological indicatir

Back 22

once a day and if a new lot number is used

Front 23

Routine biological testing of steam sterilizers should be performed no less then

Back 23

weekly

Front 24

All loads containing implantable devices should be

Back 24

monitored with a biological indicator

Front 25

For testing of rigid sterilization containers, the biological indicators should be placed

Back 25

as recommended by the manufacturer of the container

Front 26

Sterile packs are most vulnerable to contamination

Back 26

when the package is still hot

Front 27

Items being unloaded from the steam sterilizer should be handled with

Back 27

clean hands

Front 28

A loaner instrument has been contaminated during a procedure and the OR wants to sterilize it in the immediate-use steam sterilizer. What would be the first step to take

Back 28

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

Front 29

Best defines "superheating" of steam

Back 29

heat added to dry steam in the absence of water

Front 30

Sterilization method that would require aeration after processing

Back 30

Ethylene oxide

Front 31

The basic parameters of gas sterilization in a 100% ethylene oxide sterilizer are

Back 31

concentration, exposure time, humidity and temperature

Front 32

Sterilizer that requires only a special electrical outlet for installation

Back 32

Low-temperature gas plasma

Front 33

All devices processed by low-temperature gas plasma must be

Back 33

clean and dry

Front 34

Action that should be taken when a positive BI demonstrates a sterilization process, failure, and the failure is the result of an operator error

Back 34

the error should be corrected and the load reprocessed

Front 35

Generally, the ethylene oxide process challenge device (Biological Test Pack) is placed in the

Back 35

geometric center of the load

Front 36

The AAMI recommends that rigid sterilization containers be biologically tested before purchase and annually to verify that the

Back 36

sterilizer is able to sterilize the contents

Front 37

In qualification testing of steam sterilizers, to establish a baseline for the sterilizer's performance, when should the BI process challenge device (PCD) test be performed

Back 37

before the Bowie-Dick tests

Front 38

Should not be processed in the low-temperature gas plasma sterilizers

Back 38

gauze sponges

Front 39

The parameters for low-temperature gas plasma sterilization are

Back 39
