INTRODUCTION
The purpose of this comprehensive assessment is to evaluate the
competency and readiness of candidates seeking certification in
sterile processing. This exam measures the essential skills and
knowledge required to ensure the safety and efficacy of surgical
instruments and medical devices. The assessment is composed of
multiple-choice and scenario-based questions that mirror the
,challenges faced in a modern healthcare environment. Candidates
will be tested on their ability to apply theoretical concepts to real-
world applications, emphasizing critical thinking and informed
decision-making. By maintaining high standards of sterilization and
decontamination, technicians play a vital role in preventing
healthcare-associated infections and ensuring patient safety.
SECTION ONE: QUESTIONS 1–100
1. Which of the following is the minimum recommended air
exchange rate per hour in the decontamination area?
A. 4
B. 6
🟢 C. 10
D. 15
🔴 RATIONALE: Standard guidelines (ANSI/AAMI) require a
minimum of 10 air exchanges per hour in the decontamination area
to reduce the concentration of airborne contaminants and ensure
technician safety.
2. A technician is processing a heat-sensitive flexible
endoscope. Which of the following methods is most
, appropriate for high-level disinfection?
A. Steam sterilization
B. Dry heat
🟢 C. Glutaraldehyde
D. Autoclave
🔴 RATIONALE: Glutaraldehyde is a liquid chemical disinfectant
used for high-level disinfection of semi-critical items, such as
flexible endoscopes, that cannot withstand the high temperatures
of steam sterilization.
3. What is the first step in the decontamination process?
🟢 A. Manual or mechanical cleaning
B. High-level disinfection
C. Sorting by size
D. Inspection for functionality
🔴 RATIONALE: Cleaning is the essential first step in
decontamination; you cannot disinfect or sterilize an item that has
not been thoroughly cleaned of organic and inorganic debris.
4. Which organization provides the most widely recognized
standards for sterile processing and steam sterilization?
, A. OSHA
B. FDA
🟢 C. AAMI
D. EPA
🔴 RATIONALE: The Association for the Advancement of Medical
Instrumentation (AAMI) develops the standards and recommended
practices used by sterile processing professionals to ensure quality
and safety.
5. When loading a steam sterilizer, how should basins be
positioned to ensure effective air removal and moisture
drainage?
A. Flat on the rack
🟢 B. On their edge (on side)
C. Upside down
D. Stacked inside each other
🔴 RATIONALE: Placing basins on their side allows for efficient air
displacement and prevents the collection of condensate, which can
cause wet packs.
6. Which type of microorganism is the most resistant to the
sterilization process?
