What are types of automatic cleaning (2)? How effective is it? -
CORRECT ANSWER >>>>washer and ultrasonic, more effective than
manual cleaning
Pre-vacuum autoclave (Dynamic air removal)- type, temp,
porous/lumen vs non porous time - CORRECT ANSWER >>>>-steam
sterilization
-sucks air out of chamber and the steam comes in cleaning the
instruments
-clean drains are essential
-270-276 degrees F
-porous/lumen items in for 4 mins
-nonporous items in for 3 mins

Gravity displacement autoclave- type, temp, porous/lumen,
nonporous items - CORRECT ANSWER >>>>steam forces air from
chamber
thermometer closes drain
270-276 degrees F
porous/lumen items in for 10 mins
nonporous items in for 3 mins
always follow IFUs
How do you avoid condensation when sterilizing items? what
should you allow between trays? when should you remove the
trays? where should you place the trays after sterilizing? what does
it mean when the tray is moist? what should you not do to cool
down the instruments? - CORRECT ANSWER >>>>Allow airflow
between trays
remove loads immediately (leaving door ajar to cool increases
likelihood of condensation)
Don't put hot items on a cool solid surface or rack
If condensation occurs and the items are moist, they are
considered unsterile
What are the 6 chemical indicators? 1,2 and 5 are most important.
what are the 4 parameters of sterilization? - CORRECT ANSWER
>>>>1. temp/heat, the tray go hot enough, external factor.
2. pressure/bowie dick- tests all air was removed and enough
pressure was present only prevac, only tells vacuum was used
3. single parameter (based on manufacturer) quality
4. multi-parameter (based on manufacturer) (ex quality and time)
5. integrated (all parameters like time, temp, pressure and quality
of steam)
,3|Page
6. emulating indicator (all parameters of a particular style like
manufacturer for specific autoclave for a specific cycle
Chemical indicators only indicate whether that specific cycle was
met. Does not determine sterilization
What indicator are external indicators? - CORRECT ANSWER >>>>1
- heat
What indicator are Bowie dick tests? - CORRECT ANSWER >>>>2 -
pressure (used with pre-vac)
IUSS- how can the item be wrapped? what kind of indicator must
be used? what item cannot be used unless its an emergency? what
process must still occur when using IUSS? what must you keep for
patient safety? wrapped vs unwrapped goods length of tie and
temperature? - CORRECT ANSWER >>>>no packaging, wrapped
items or textiles due to an abbreviated dry time
same decon process
rigid sterilization containers with lid
must use a class 5 chemical indicator
never an implant unless emergent
sterilization log must be kept for patient safety
Unwrapped goods: 3-5 minutes at 270-275°F (132-135°C)
Wrapped goods: 6-10 minutes at 270-275°F
What happens if the IUSS fails a quality check? - CORRECT ANSWER
>>>>If a QC fails, run 3 consecutive a spore tests
If one fails again, biomed checks IUSS and has to pass 3 consecutive
tests to use it again

Gluteraldehyde- What kind of sterilization? where is this used? how
long does it take? is it often used, why? - CORRECT ANSWER
>>>>cold sterilization
POC use only
Takes 10 hours of immersion
Bad for instruments due to pitting
Suboptimal form of sterilization due to environmental problems
and poor ease of use
Ethylene oxide- what can it be used on? how long does it take?
how long is aeration time? is it often used, why? what temperature
and humidity does EO need to be*? - CORRECT ANSWER >>>>cold
and dry form of sterilization
for heat + moisture sensitive items (99-145 degree F and 45-75%
humidity)
2-5 hours exposure
8-12 hour aeration time
Human carcinogen (exposure limited to 1PPM in an 8 hr period)
Lumens must be completely dry (great for foleys)
Environmentally hazardous
Will make antifreeze with water
baccilus atropheus
Low Temp Hydrogen Peroxide Plasma Sterilization (aka Sterrad or
VPRO)- What is it good for? How long does it take? How long is
aeration? How does it work? - CORRECT ANSWER >>>>- Use for
heat + moisture sensitive items
- No aeration cycle needed - dry sterilization
- Cycle time 75 mins
- Environmentally sound
