Answer Format
All correct answers are highlighted in bold and green, with rationales that explain sterile
processing priorities, reinforce compliance with safety and regulatory standards, and strengthen
applied knowledge for exam readiness.
1. What is the first step in the decontamination process for surgical
instruments?
a) Sterilization
b) Cleaning
c) Packaging
d) Inspection
b) Cleaning
Rationale: Cleaning removes visible debris and bioburden, preparing instruments for further
processing.
2. Which sterilization method is most suitable for heat-sensitive
instruments?
a) Steam sterilization
b) Ethylene oxide (EO) sterilization
c) Dry heat sterilization
d) Flash sterilization
,b) Ethylene oxide (EO) sterilization
Rationale: EO sterilization uses low temperatures, ideal for heat-sensitive instruments.
3. What is the purpose of a biological indicator in sterilization?
a) Monitors temperature
b) Verifies sterility by testing for microbial survival
c) Checks packaging integrity
d) Measures chemical concentration
b) Verifies sterility by testing for microbial survival
Rationale: Biological indicators use resistant spores to confirm sterilization effectiveness.
4. What is a nosocomial infection?
a) Infection acquired in the community
b) Infection acquired in a healthcare facility
c) Infection caused by a virus
d) Infection treated with antibiotics
b) Infection acquired in a healthcare facility
Rationale: Nosocomial infections are hospital-acquired due to improper sterilization or hygiene.
5. What is the correct temperature range for steam sterilization at 270°F?
a) 121–123°C
b) 132–135°C
c) 100–110°C
d) 140–150°C
b) 132–135°C
Rationale: 270°F corresponds to 132–135°C, standard for steam sterilization.
6. Which PPE is required during decontamination?
a) Gloves only
b) Gloves, gown, mask, and eye protection
c) Mask only
d) Gown only
b) Gloves, gown, mask, and eye protection
Rationale: Full PPE protects against biohazards during decontamination.
7. What does a chemical indicator in a sterilization package show?
a) Confirms microbial death
b) Indicates exposure to sterilization conditions
c) Tests packaging material
d) Measures humidity
b) Indicates exposure to sterilization conditions
Rationale: Chemical indicators confirm exposure to conditions like temperature or gas but not
sterility.
8. Which microorganism is most resistant to sterilization?
a) Escherichia coli
, b) Bacillus atrophaeus
c) Staphylococcus aureus
d) Pseudomonas aeruginosa
b) Bacillus atrophaeus
Rationale: Bacillus atrophaeus spores are highly resistant, used in biological indicators.
9. How should instruments with lumens be cleaned?
a) Soak in water
b) Flush with enzymatic detergent and brush
c) Wipe with alcohol
d) Sterilize without cleaning
b) Flush with enzymatic detergent and brush
Rationale: Lumens require flushing and brushing to remove debris effectively.
10. What is the minimum exposure time for steam sterilization at 270°F?
a) 1 minute
b) 4 minutes
c) 10 minutes
d) 15 minutes
b) 4 minutes
Rationale: 4 minutes is the standard exposure time for wrapped instruments at 270°F.
11. What is a sterile processing technician’s role in infection control?
a) Diagnosing infections
b) Ensuring instruments are free of microbes
c) Administering antibiotics
d) Performing surgery
b) Ensuring instruments are free of microbes
Rationale: Technicians ensure instruments are clean and sterile to prevent infections.
12. Which organization sets sterile processing standards?
a) FDA
b) AAMI
c) OSHA
d) CDC
b) AAMI
Rationale: AAMI provides guidelines for sterile processing, such as AAMI ST79.
13. What should be done if a biological indicator test fails?
a) Release the load
b) Recall and reprocess the load
c) Ignore the result
d) Adjust sterilizer settings
b) Recall and reprocess the load
Rationale: A failed biological indicator indicates potential sterility failure, requiring
reprocessing.
