knob sterilize

(wait for correct temperature and pressure) set timer to 20 min

ultrasonic cleaner

a device that loosens and a removes debris with the use of sound waves traveling through a liquid

chemical vapor sterilizer

a piece of equipment that is used for sterilizing by means of hot formaldehyde vapors under pressure

autoclave

a piece of equipment that is used for sterilizing by means of moist heat under pressure

dry heat sterilization

a piece of equipment used for sterilization by confirming that all spore-forming microorganisms have been destroyed

sterilization

a process intended to kill all microorganisms and is the highest level of microbial destruction(spores)

endospore

a resistant, dormant structure that is formed inside of some bacteria and can withstand adverse conditions

sterilant

an agent capable of killing microorganisms

static air

an example of dry heat sterilization is

multi-parameter indicator

an indicator that reacts to time, temp, and the presence of steam

critical instrumnet

an instrument used to penetrate bone or soft tissue

disinfection

contact time of less than 10 hours of chemical sterilization

no

do process integrators indicate sterility

process integrator

dot inside

process indicator

dot outisde

through percutaneous injury or contact with mucous membranes of the eyes, nose, or mouth

how can exposure occur

disinfect it

how do you clean noncritical instruments

flush water through it for 20-30 sec

how do you prepare a high-speed handpiece for sterilization

with sterile water

how do you rinse instruments that have been processed in a liquid chemical sterilant

with cold water

how do you rinse instruments that have been processed in an ultrasonic

on a tray or plastic bin

how do you transport instruments

5 min for saliva and 15 min for surgery

how long does it take to clean in the ultrasonic

weekly

how often should biological monitoring be tested

once a day

how often should the solutions be thrown away

process indicators

identity instrument packs that have been exposed to a certain temperature

they should be placed in a holding solution

if the instruments cannot be processed immediately what should be done with them

the monitoring service immediately gives a phone call to the dental office

if the spore test is failed

noncritical

instruments that come in contact wih the skin only

semicritical

instruments that come in contact with oral tissues but do not penetrate it or bone

FDA approved

kitchen dishwashers cannot be used to pre-clean instruments because they're not

physical monitoring

looking at the gauges and readings

event related packaging

means that it is assumed the contents of a package will remain sterile indefinitely unless the packaging is complete

knob vent

open chamber slightly after a few minutes allows instruments to dry

rinse with water disinfected and rinsed again and dried

process of ultrasonic cleaner

chemical sterilization

requires 10 hours of contact time; anything less than 10 hours is disinifection

use of lubrication

rusting of instruments can be prevented by

from dirty to clean to sterile to storage without ever doubling back

single loop

single parameter indicator

tapes, strips, and tabs with heat sensitive chemical change when exposed to a certain temperature

single loop

the basic rule of the workflow pattern is an instrument-processing area

critical, semicritical, and noncritical

the instrument classifications used to determine that the method of sterilization and disinfection

use life

the length of time that a germicidal solution is effective after it has been prepared for use

clean area

the sterilization center where contaminated items are brought for precleaning

knob fill

to line at bottom of chamber with distilled water

biological monitoring

verifies sterilization by confirming that all spore-forming microorganisms have been destroyed

biological indicator

vials or stripes, also known as spore tests, that contain harmless bacterial spores and are used to determine whether a sterilizer is working

sound waves

what does an ultrasonic use to work

critical and semicritical

what instruments do you have to sterilize

instruments will not rust

what is the major advantage of chemical vapor sterilization

biological monitoring

what is the only way to deteremine sterilization

heavy gloves

what is worn while handling instruments

steam and chemical vapor

what type of heat sterilization is apporpiate for high speed handpieces

goggle-type eyewear

what type of personal protective equipment is necessary when one is processing instruments

inability to wrap items

what's the primary disadvantage of flash sterilization

250 F for 30 min

whats the temperature and time for sterilization

hand scrubbing, ultrasonic cleaning, and with the thermal washer and disinfector

which are the methods of precleaning

physical, chemical, and biological

which is the form of sterilization monitoring

hand scrubbing

which method of precleaning instruments is least desirable

they will cause holes in the packaging

why pins staples and paper clips are not used on instrument packaging

maintain sterility and organization

why should instruments be packaged for sterilization
