CNOR Review Points: Sterilization
(Subject Area 5) 2025
1 - Correct Answers-class ___ chemical indicators are placed outside of the package
and identify if the package has been subjected to the sterilization process
10; 3 - Correct Answers-for gravity displacement steam sterilizer:
- contents that are porous and have a lumen = ___ minutes
- contents that are non-porous and have no lumen = ___ minutes
140; cotton muslin; 75; rehydrated - Correct Answers-steam sterilization of woven fabric
requirements:
- ___-thread count
- carded
- 100% ___
- may be laundered up to ___ times before it should be discarded due to excessive
wearing, which will prevent it from providing an effective microbial barrier
- prior to reuse, the woven material should be ___ through laundering, as the moisture
level of the woven material is important for steam sterilization
2 - Correct Answers-class ___ chemical indicator:
- specialty (autoclave test pack, Bowie Dick)
- tests for presence of air in the sterilizer chamber of a dynamic air removal
(prevacuum) steam sterilizer
2-6 - Correct Answers-class ___-___ chemical indicators are placed inside the package
27, 270-275 (132-135 degrees C) - Correct Answers-IUSS involves a high-speed
pressure sterilizer that operates at a pressure of ___ psi to increased the temperature in
the chamber to between ___-___ degrees F
270 (132.2 degrees C) - Correct Answers-for steam sterilization, temperature reaches
___ degrees F
270 (132.2 degrees C), 4 - Correct Answers-proper cycle to sterilize a set of wrapped
instruments in a dynamic air removal (prevacuum) steam sterilizer is ___ degrees F for
___ minutes
, 3 - Correct Answers-class ___ chemical indicator:
- checks single variable/parameter
- time, temperature, or pressure
- reacts to one critical process parameter
3 - Correct Answers-minimum exposure time of an unwrapped, non-porous, stainless
steel item undergoing IUSS at 270 degrees F (132 degrees C) is ___ minutes
4 - Correct Answers-class ___ chemical indicator:
- checks multiple variables/parameters
- dry heat
- reacts to two or more critical process parameters
5 - Correct Answers-class ___ chemical indicator should be used for all implantable
devices
5 - Correct Answers-class ___ chemical indicator should be used to monitor sterilizers
used for IUSS every load
5 - Correct Answers-class ___ chemical indicator:
- reacts to all critical process parameters
- used for all implantable devices
- should be used to monitor sterilizers used for IUSS every load
6 - Correct Answers-class ___ chemical indicator:
- emulating process challenge pack
- does NOT replace biologic indicator
- reacts to all the critical parameters of a specialized sterilization cycle
biologic - Correct Answers-___ sterilization indicators:
- check the effectiveness of steam sterilizers
- validate system functioning
biologic - Correct Answers-___ sterilization indicators:
- geobacillus stearothermophilus
- bacillus atrophaeus
- sterilization process-monitoring device that uses a known population of highly resistant
spores to test the effectiveness of the sterilization process being used
- when bacteria inside the indicator die during sterilization, the indicator is considered
negative, which validates the effectiveness of the sterilization
