Introduction
This examination assesses the professional knowledge and applied
judgment required of sterile processing technicians preparing for
CBSPD certification. It evaluates understanding of roles and
responsibilities, life science principles, decontamination and
disinfection procedures, instrument preparation and packaging,
sterilization methods and monitoring, sterile storage and
distribution, patient care equipment processing, and professional
ethics. Items are presented as multiple-choice and scenario-based
questions requiring candidates to analyze realistic sterile processing
scenarios and select the most appropriate, evidence-based course of
action. The examination emphasizes real-world application,
regulatory adherence, patient safety, and critical decision-making in
central service environments.
SECTION ONE: QUESTIONS 1–110
,1. What is the primary purpose of the Central Service/Sterile
Processing Department?
A. To sterilize all medical instruments
B. To manage hospital inventory
🟢 C. To provide dependable service to enhance patient care
D. To maintain surgical equipment
🔴 RATIONALE: The overall role of the CS/SPD is to provide
dependable service to enhance patient care by supplying safe,
sterile instruments and supplies. Sterilization, inventory
management, and equipment maintenance are components of
this role but do not encompass its primary purpose.
2. Which government agency regulates environmental
disinfectants?
A. FDA
B. CDC
🟢 C. EPA
D. OSHA
🔴 RATIONALE: The Environmental Protection Agency regulates
environmental disinfectants and evaluates their efficacy for use on
environmental surfaces. The FDA regulates medical devices, the
CDC provides infection control guidelines, and OSHA regulates
workplace safety.
3. Why is it important to evenly distribute large instruments in a
set?
A. It prevents damage to the instruments
B. It ensures proper sterilization time
🟢 C. Extra condensation will make the set more difficult to dry
D. It reduces the weight of the set
,🔴 RATIONALE: Evenly distributing large instruments prevents
moisture accumulation that can prevent proper drying and
potentially compromise sterility. While preventing damage and
ensuring sterilization time are important, the primary reason
relates to condensation and drying.
4. What is the first and most critical step in the sterilization
process?
A. High-temperature drying
B. Proper packaging
🟢 C. Thorough cleaning
D. Correct sterilizer cycle selection
🔴 RATIONALE: Thorough cleaning is the first and most critical
step because organic and inorganic residues can shield
microorganisms from sterilant, causing sterilization failure. All
subsequent steps depend on effective cleaning.
5. Which of the following is a high-level disinfectant?
A. Isopropyl alcohol 70%
B. Quaternary ammonium compounds
🟢 C. Glutaraldehyde
D. Phenolics
🔴 RATIONALE: Glutaraldehyde is a high-level disinfectant and
chemical sterilant. Isopropyl alcohol is intermediate-level, while
quaternary ammonium compounds and phenolics are low-level
disinfectants.
6. The Bowie-Dick test is used to evaluate:
A. Sterilizer temperature accuracy
B. Biological indicator growth
🟢 C. Steam penetration and air removal in a pre-vacuum
, sterilizer
D. Chemical indicator color change
🔴 RATIONALE: The Bowie-Dick test is performed daily to check
for air leaks and adequate air removal from the chamber of pre-
vacuum steam sterilizers. It evaluates steam penetration, not
temperature accuracy or biological growth.
7. Which biological indicator is used for steam sterilization?
A. Bacillus atrophaeus
B. Mycobacterium terrae
🟢 C. Geobacillus stearothermophilus
D. Clostridium sporogenes
🔴 RATIONALE: Geobacillus stearothermophilus is the biological
indicator used for steam sterilization cycles. Bacillus atrophaeus is
used for ethylene oxide and dry heat.
8. The function of a ratchet can be checked by:
A. Opening and closing the ratchet repeatedly
🟢 B. Closing the ratchet on the first click, then tapping the
handle on the worktable
C. Checking the ratchet under magnification
D. Testing the ratchet with a gauge
🔴 RATIONALE: Closing the ratchet on the first click and tapping
the handle on the worktable tests whether the ratchet opens
unexpectedly, indicating a defect. Repeated opening and closing
may not reveal functional failure.
9. Which agency requires that eyewash stations be available for
emergency use?
