Standards, AAMI & OSHA Guidelines, Packaging & Storage Protocols,
Quality Assurance, Documentation & Equipment Maintenance
,Question 1:
What is the primary purpose of sterilization in a healthcare setting?
A) To clean surfaces
B) To eliminate all microorganisms
C) To reduce odors
D) To sanitize instruments
Correct Option: B
Rationale: The primary purpose of sterilization is to ensure that all forms of
microorganisms, including bacteria, viruses, fungi, and spores, are completely
destroyed. This is crucial in preventing infections and ensuring patient safety during
medical procedures.
Question 2:
Which method is commonly used for sterilizing heat-sensitive medical
instruments?
A) Steam sterilization
B) Dry heat sterilization
C) Ethylene oxide gas sterilization
D) Boiling water
Correct Option: C
Rationale: Ethylene oxide gas sterilization is a method used for heat-sensitive
instruments that cannot withstand high temperatures. It effectively penetrates
packaging materials and kills microorganisms while being safe for delicate equipment.
Question 3:
What is the recommended minimum exposure time for steam sterilization at 121°C
(250°F)?
A) 10 minutes
B) 30 minutes
C) 60 minutes
D) 15 minutes
Correct Option: B
Rationale: The recommended minimum exposure time for steam sterilization at 121°C
is 30 minutes. This duration ensures adequate penetration of steam and sufficient time
to achieve sterilization of the items being processed.
Question 4:
, Which of the following is NOT a component of the sterile processing cycle?
A) Decontamination
B) Sterilization
C) Packaging
D) Distribution
Correct Option: C
Rationale: While packaging is an essential part of preparing items for sterilization, it is
not a phase of the sterile processing cycle itself. The main components include
decontamination, sterilization, and distribution, focusing on safely handling and
providing sterile instruments for use.
Question 5:
When should personal protective equipment (PPE) be worn in the sterile
processing department?
A) Only when handling dirty instruments
B) Only during sterilization
C) At all times when exposed to potential contaminants
D) Only during inspections
Correct Option: C
Rationale: PPE is essential to protect sterile processing technicians from exposure to
contaminants and infectious materials. It should be worn at all times when there is a
risk of exposure, thus maintaining a safe environment for both staff and patients.
Question 6:
What is the primary method for monitoring the effectiveness of a sterilization
process?
A) Visual inspection
B) Chemical indicators
C) Biological indicators
D) Temperature logs
Correct Option: C
Rationale: Biological indicators are the most effective way to monitor sterilization
processes as they contain viable microorganisms that can only be killed during effective
sterilization. This ensures that sterilization has occurred correctly.
Question 7:
Which type of packaging is appropriate for steam sterilization?
A) Woven textile wraps
B) Plastic bags
