CNOR PRACTICE TEST NEWEST 2024 ACTUAL EXAM TEST BANK COMPLETE QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS)

Critical items - ANSWERS,must be sterile and will enter sterile tissue or the vascular system
Semi-critical - ANSWERS,should be sterile but high-level disinfection is acceptable if manufacturer's
instructions require
contacts broken skin or mucous membranes
Sterilization - ANSWERS,kills everything
High-level disinfection - ANSWERS,kills everything but spores
Non-critical - ANSWERS,Intermediate or low-level disinfection or cleaning; will come in contact with
skin
Critical examples - ANSWERS,instruments, cutting endoscopic accessories and scopes, cardiac and
urinary catheters, needles
Semi-critical examples - ANSWERS,RT/anesthesia equipment, bronchoscopes/GI endoscopes
Non-critical examples - ANSWERS,OR beds, linens, tourniquets
SPD workflow - ANSWERS,Decon, prep + pack, sterile processing, clean distribution/storage
SPD layout - ANSWERS,Must have a physical separation between a decon and processing area;
negative pressure in decon and positive pressure in sterile side
Decon of instruments - ANSWERS,cleaning is the most critical step to prevent infection
pre-treating is recommended with non-drying enzymatic agent to prevent biofilm on instruments
disassemble anything that can be
brush lumens, channels, crevices, and joints
brush must have diameter of lumen and go through entire length of lumen
Automated cleaning - ANSWERS,washer and ultrasonic, more effective than manual cleaning
Pre-vac (Dynamic air removal) - ANSWERS,sucks air out of chamber
clean drains are essential
270-276 degrees F
porous/lumen items in for 4 mins
nonporous items in for 3 mins
Gravity displacement autoclave - ANSWERS,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? - ANSWERS,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? - ANSWERS,1. heat
2. pressure
3. single parameter
4. multi-parameter
5. integrated (all parameters like time, temp, pressure and quality of steam)
6. emulating indicator (all parameters of a particular style like manufacturer for specific autoclave
for a specific cycle
What indicator are external indicators? - ANSWERS,1 - heat
What indicator are Bowie dick tests? - ANSWERS,2 - pressure (used with pre-vac)
IUSS - ANSWERS,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
What happens if the IUSS fails? - ANSWERS,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 - ANSWERS,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 - ANSWERS,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)
Banned in Europe in 1980s
