1. A surgical instrument labeled as “lumened” indicates which of the
following?
A. It has a serrated surface
B. It is designed for orthopedic use
C. It contains an internal channel
D. It must be sterilized using chemical sterilization
Because “lumened” refers to instruments with internal channels or
hollow passages that require special cleaning attention to ensure all
surfaces are free of bioburden.
2. The most effective method to monitor the mechanical function of a
steam sterilizer cycle is:
A. Chemical integrators
B. Mechanical gauges and printouts
C. Biological indicators
D. Bowie-Dick tests
Mechanical monitors directly record the sterilizer’s cycle parameters
(time, temperature, pressure) and verify proper function, whereas
biological and chemical indicators assess sterility outcomes.
3. Which of the following is the BEST way to prevent corrosion of
stainless steel instruments?
, A. Dry with a cotton towel
B. Store in sealed plastic bags
C. Thoroughly dry instruments after washing
D. Soak in enzymatic solution overnight
Moisture trapped on instruments promotes corrosion, so complete
drying after cleaning prevents rust and pitting in stainless steel.
4. A quality assurance program in sterile processing should include which
of the following?
A. Only random equipment checks
B. Ongoing evaluation and documentation of processes
C. Sterilizer monitoring once per quarter
D. Annual staff competency evaluations only
QA programs require continuous process evaluation and
documentation to ensure safety and regulatory compliance.
5. The purpose of the “flash sterilization” process is to:
A. Reduce instrument shelf life
B. Sterilize only non-critical items
C. Quickly sterilize unwrapped instruments for immediate use
D. Sterilize wrapped instrument sets
Flash sterilization is intended for unwrapped or immediately needed
items when standard processing is not feasible.
6. Which of the following items would be classified as semi-critical?
A. Blood pressure cuff
B. Stethoscope
C. Endotracheal tube
D. Hospital bed rail
Semi-critical items contact mucous membranes or non-intact skin
and require high-level disinfection.
7. The first step in decontamination of used surgical instruments is:
A. Drying
B. Cleaning
C. Sterilization
D. Packaging
Cleaning removes bioburden and is essential before any disinfection
or sterilization can be effective.
, 8. What is the primary purpose of an enzymatic detergent in sterile
processing?
A. To disinfect instruments
B. To polish instruments
C. To break down organic material like blood and tissue
D. To lubricate instruments
Enzymatic detergents contain proteases and other enzymes that
break down organic debris for thorough cleaning.
9. Biological indicators are used to verify:
A. Chemical concentration
B. Temperature accuracy only
C. Sterilization efficacy by killing resistant microorganisms
D. Humidity levels in sterilizer
Biological indicators contain resistant spores and verify that
sterilization conditions were sufficient to kill them.
10. The recommended storage condition for sterile instrument
packs is:
A. Near steam pipes
B. In direct sunlight
C. In a clean, dry area with controlled humidity
D. On the floor
Sterile packs must be stored in a controlled environment to maintain
sterility until use.
11. Ultrasonic cleaners primarily remove debris by:
A. Chemical action alone
B. High-frequency sound waves causing cavitation
C. Manual scrubbing
D. Heat sterilization
Ultrasonic cleaners use cavitation bubbles created by sound waves to
dislodge debris from instruments.
12. The term “aseptic technique” refers to:
A. Only sterilization processes
B. Only wound care
C. Practices that prevent contamination of sterile items
D. Routine handwashing
