Question 1
Which department is primarily responsible for decontaminating reusable surgical instruments
before they are sterilized?
A. Operating Room
B. Sterile Storage
C. Decontamination Area
D. Case Cart Assembly
Correct Answer: C. Decontamination Area
Solution:
The decontamination area is where contaminated instruments are received, sorted, cleaned, and
disinfected before inspection and sterilization. This area minimizes the spread of contaminants
and serves as the first step in instrument reprocessing.
Question 2
What is the primary purpose of mechanical cleaning equipment such as ultrasonic cleaners?
A. Sterilize instruments
B. Lubricate hinged instruments
C. Remove soil from hard-to-reach surfaces
D. Dry surgical instruments
Correct Answer: C. Remove soil from hard-to-reach surfaces
Solution:
Ultrasonic cleaners use high-frequency sound waves to create microscopic bubbles (cavitation),
which effectively remove debris from joints, hinges, serrations, and other difficult-to-clean areas.
They clean but do not sterilize instruments.
Question 3
,A biological indicator is used to verify:
A. The package is sealed properly.
B. Sterilization conditions were sufficient to destroy bacterial spores.
C. The sterilizer door closed correctly.
D. Instruments are completely dry.
Correct Answer: B. Sterilization conditions were sufficient to destroy bacterial spores.
Solution:
Biological indicators contain highly resistant bacterial spores and provide the highest level of
assurance that sterilization conditions were adequate to achieve sterility.
Question 4
What is the recommended action if an instrument package becomes wet after sterilization?
A. Store it as usual.
B. Dry it with a towel.
C. Consider it contaminated and reprocess it.
D. Label it "Use First."
Correct Answer: C. Consider it contaminated and reprocess it.
Solution:
Moisture can permit microorganisms to wick through packaging material. Any wet package
should be considered contaminated and must be reprocessed before patient use.
Question 5
Which of the following best describes event-related shelf life?
A. Sterility expires after exactly one year.
B. Sterility depends on package integrity and handling rather than time.
C. All sterilized items expire after six months.
D. Packages never expire.
Correct Answer: B. Sterility depends on package integrity and handling rather than time.
Solution:
Modern sterile storage practices use event-related shelf life, meaning sterility is maintained until
an event such as damage, moisture, or contamination compromises the package.
,Question 6
When inspecting surgical instruments, a technician should FIRST check for:
A. Manufacturer's logo
B. Cleanliness and proper function
C. Cost of replacement
D. Color of instrument handles
Correct Answer: B. Cleanliness and proper function
Solution:
Every instrument should be inspected for cleanliness, proper alignment, sharpness, cracks,
corrosion, and correct function before assembly and sterilization.
Question 7
Which sterilization monitoring method provides immediate information after a cycle?
A. Biological indicator
B. Chemical indicator
C. Spore test culture
D. Environmental culture
Correct Answer: B. Chemical indicator
Solution:
Chemical indicators change color when exposed to specific sterilization parameters, providing
immediate evidence that the package or load has been exposed to the sterilization process. They
do not confirm sterility like biological indicators.
Question 8
The purpose of a Bowie-Dick test is to evaluate:
A. Steam quality
B. Air removal and steam penetration in a pre-vacuum steam sterilizer
C. Biological spore destruction
D. Instrument cleanliness
Correct Answer: B. Air removal and steam penetration in a pre-vacuum steam sterilizer
, Solution:
The Bowie-Dick test is performed daily before processing loads in dynamic air-removal (pre-
vacuum) steam sterilizers to verify effective air removal and steam penetration.
Question 9
Why should heavy instrument sets generally be placed on lower sterilizer racks?
A. They cool faster.
B. They prevent lighter packages from being crushed.
C. They sterilize more quickly.
D. They require less steam exposure.
Correct Answer: B. They prevent lighter packages from being crushed.
Solution:
Placing heavier trays on lower shelves prevents damage to lighter items, promotes safe loading,
and helps maintain package integrity throughout sterilization.
Question 10
What information should be included in sterilization load documentation?
A. Employee's favorite instrument
B. Patient diagnosis only
C. Sterilizer identification, cycle parameters, load number, operator, and monitoring results
D. Operating room schedule
Correct Answer: C. Sterilizer identification, cycle parameters, load number, operator, and
monitoring results
Solution:
Accurate documentation supports quality assurance and traceability. Essential information
includes the sterilizer used, load number, date, cycle parameters, operator identification, and the
results of mechanical, chemical, and biological monitoring when applicable.
Question 11
Which of the following should be done before placing instruments into an ultrasonic cleaner?
A. Dry the instruments completely
B. Rinse off gross soil
C. Sterilize the instruments
D. Lubricate all hinged instruments
