Sterile Processing Quiz
Questions: 16 · 10 minutes
1. A reusable instrument has a narrow internal channel. Which cleaning approach is most appropriate?
Wipe only the exterior because detergent will diffuse through the channel
Soak the instrument without flushing so loosened debris stays contained
Use the specified flushing method and a correctly sized channel-cleaning device according to the instructions for use
Pass any available wire through the channel until it emerges from the other end
2. Inspection reveals damaged insulation on a reusable electrosurgical instrument. What is the appropriate response?
Cover the defect with sterilization indicator tape
Place the damaged area beneath another instrument in the tray
Continue using it for procedures that require lower power settings
Remove the instrument from service and route it for evaluation, repair, or replacement
3. Before cleaning a hinged, multipart instrument, what generally improves access to contaminated surfaces?
Lubricate it before removing visible soil
Keep it closed to protect its alignment during cleaning
Wrap delicate joints before placing it in detergent
Open, unlock, and disassemble it as directed by its instructions for use
4. Why must reusable instruments be adequately cleaned before disinfection or sterilization?
Cleaning alone guarantees that all microorganisms have been destroyed
Residual soil can interfere with the effectiveness of later processing steps
Cleaning replaces the need to inspect instruments for damage
Sterilization is intended only to remove visible organic material
5. A wrapped package is visibly wet when removed after a completed steam-sterilization cycle. What is the best response?
Place it on an open shelf until the wrapper looks dry
Do not release it for use; handle and investigate it according to facility policy, including reprocessing when required
Use it first because moisture shortens its acceptable storage time
Add an external chemical indicator and return it to storage
6. While manually brushing an immersed instrument, which technique best limits splashing and aerosol formation?
Lift the instrument above the solution so the brush strokes are visible
Use rapid back-and-forth strokes at the surface of the solution
Keep the instrument and brush below the solution surface while cleaning, when permitted
Use compressed air to loosen soil before brushing
7. After a cleaning cycle, dried material remains visible in a box lock. What should happen next?
Apply lubricant over the material so the joint can move freely
Return the instrument for appropriate recleaning and repeat inspection before further processing
Wipe the outside and release it if the jaws appear clean
Package the instrument separately and increase sterilization exposure
8. During visual inspection, a technician suspects a hairline crack near an instrument joint. What is the most useful next step?
Inspect it under appropriate lighting and magnification, following the facility’s inspection process
Close the joint and assume normal resistance indicates it is intact
Sterilize it first because heat will make the crack easier to see
Apply extra lubricant and return it to the set if movement improves
9. Which workspace arrangement best reduces cross-contamination during instrument processing?
Clean and contaminated items share a counter if they are placed on different towels
Finished sets return through decontamination so staff can maintain visual control
Work progresses from contaminated areas toward clean preparation and sterilization areas without backtracking
All processing activities occur in one room, with cleaning performed at the end of each shift
10. A sharp instrument is discovered beneath cloudy solution in a basin. How should it be retrieved?
Use an appropriate tool, such as forceps, to retrieve it without reaching into the basin by hand
Reach in slowly with two pairs of gloves to improve puncture protection
Send the full basin into automated equipment without identifying its contents
Drain the basin and feel for the instrument through a utility glove
11. A newly purchased delicate instrument is scheduled for ultrasonic cleaning. What should be confirmed before placing it in the unit?
That another instrument of similar size has previously tolerated the cycle
That the instrument can rest directly on the bottom of the ultrasonic chamber
That ultrasonic cleaning is permitted by the instrument’s instructions and the selected cycle is compatible
That the longest available cycle is selected for the first cleaning
12. After the final rinse, which action best prepares a cleaned instrument for inspection and subsequent processing?
Place it in an unrestricted hallway to air-dry quickly
Seal it in a pouch while wet to prevent airborne contamination
Use instrument lubricant as a substitute for drying
Dry it thoroughly using a method allowed by its instructions for use
13. Which approach should determine the personal protective equipment used while manually cleaning contaminated instruments?
Use the same basic gloves for every task because all decontamination work has similar hazards
Wear sterile gloves so the cleaning solution remains uncontaminated
Choose PPE according to whether the instruments look heavily contaminated
Select PPE for the anticipated exposure, applicable requirements, and facility and equipment instructions
14. A freshly prepared detergent solution is producing poor cleaning results. What should staff verify first?
Whether a stronger household cleaner can be added to improve performance
Whether concentration, water quality or temperature, exposure time, and preparation match the applicable instructions
Whether hotter water can be used regardless of the detergent label
Whether the instruments can remain in the solution overnight
15. What distinguishes a biological indicator from a chemical indicator in sterilization monitoring?
A biological indicator uses resistant microorganisms or spores to assess whether lethal process conditions were achieved
A biological indicator shows only that a package was exposed to the process
A biological indicator confirms that every instrument was cleaned before packaging
A biological indicator measures whether package seals are strong enough for storage
16. A used instrument set cannot be cleaned immediately after a procedure. What is the best initial action?
Keep soil from drying with an approved point-of-use pretreatment or moistening method permitted by the instruments’ instructions for use
Immerse the entire set in saline until it can be transported
Allow the set to dry so staff can handle it more easily
Place the set directly into sterilization packaging to contain contamination
