A(n) __________ agent is used to pre-treat instruments. It is non-drying and is
NOT a disinfectant. It is something that BREAKS DOWN organic material. It
digests that organic material and makes it something that is easy to clean and
disinfect. It DISSOLVES the organic stuff and INCLUDES PROTEASES. -
ANSWER -enzymatic
The size and length of brush lumens to clean instruments is determined by the
manufacturer. - ANSWER -true
__________ is very difficult to get off instruments once it's on there. This adds
texture on instruments where spores can hide. - ANSWER -biofilm
What is considered more effective:
Automated cleaning (ultrasonic & washers) or manual cleaning? - ANSWER -
automated

gravity displacement autoclaves fall under? - ANSWER -steam
Both pre-vacuum autoclaves (dynamic air-removal) and gravity displacement
autoclaves end in a chamber full of __________ - ANSWER -steam
*Steam Sterilization*
Pre-vacuum autoclave (dynamic air-removal) OR gravity displacement autoclave?
-Sucks air out of the chamber
-Clean drains are essential
-270 degrees F-276 degrees F
-Porous/lumen items in *4 minutes*
-Nonporous in *3 minutes*
-Most commonly used today
-Very good at pulling the steam through blue filters
-Good for packaged items - ANSWER -pre-vacuum autoclave
,*Steam Sterilization*
Pre-vacuum autoclave (dynamic air-removal) OR gravity displacement autoclave?
-Steam forces air from chamber

(dynamic air-removal) or a gravity displacement autoclave? - ANSWER -pre-
vacuum autoclave
True or false?
Clean drains are essential in both pre-vacuum autoclaves (dynamic air-removal)
and gravity displacement autoclaves. - ANSWER -true
*Steam Sterilization*
Pre-vacuum autoclave (dynamic air-removal) OR gravity displacement autoclave?
Sucks air out of the chamber - ANSWER -pre-vacuum autoclave
*Steam Sterilization*
Pre-vacuum autoclave (dynamic air-removal) OR gravity displacement autoclave?
Steam forces air from chamber - ANSWER -gravity displacement autoclave
If condensation occurs after steam sterilization and the items are moist, they are
considered __________ and the sterilization process must be restarted. -
ANSWER -contaminated
True or false?
In steam sterilization, loads must be removed IMMEDIATELY because leaving
the door ajar to cool increases likelihood of condensation. - ANSWER -true
True or false?
After steam sterilization, hot items should be placed on cool solid surfaces or
racks. - ANSWER -false
The requirement for handling items after steam sterilization includes that it must
be cooled on a *lined surface* until it is easily handled with __________. -
ANSWER -bare hands
, After items are sterilized using steam sterilization, they should be placed on a
__________ surface and allowed to cool until it can easily be carried with bare
hands. - ANSWER -lined
Which of the following describes the process for gravity displacement
sterilization?
a. Steam enters the chamber at the bottom and slowly pushes the air down and out
through a discharge outlet
b. Steam enters the chamber at the bottom and slowly pushes the air up and out
through a discharge outlet
c. Steam enters the chamber at the top and slowly pushes the air down and out
through a discharge outlet
d. Steam enters the chamber at the side and slowly pushes the air out the other side
through a discharge outlet - ANSWER -c
__________ indicators include:
Class 1: Heat
Class 2: Pressure - Bowie Dick
Class 3: Single parameter
Class 4: Multi parameter
Class 5: Integrated
Class 6: Emulating indicator - ANSWER -chemical
Which 2 class indicators must every tray that we use have? - ANSWER -class 1,
class 5
Which class indicator is on the outside of the tray and is only there for verification
that the tray went through heat? - ANSWER -class 1
Which class indicator is on the inside of the tray (should be in the top of the tray
and in the corner because this is the most difficult place for steam to penetrate) -
ANSWER -class 5
Which 2 classes of chemical indicators are ALL INCLUSIVE? (Meaning there are
4 parameters of sterilization)
1. TIME
2. TEMPERATURE
