central sterile technician Interview Questions and Answers

1. What are your key responsibilities as a Central Sterile Technician?

   • Answer: My key responsibilities include receiving, inspecting, decontaminating, assembling, sterilizing, and storing medical instruments and equipment. This also involves maintaining accurate records, adhering to strict infection control protocols, and ensuring the safety and sterility of all supplies.

2. Describe your experience with different sterilization methods.

   • Answer: I am experienced in steam sterilization (autoclaving), ethylene oxide sterilization, low-temperature sterilization (e.g., hydrogen peroxide plasma sterilization), and dry heat sterilization. I understand the parameters and limitations of each method and can select the appropriate method based on the type of instrument or equipment.

3. How do you ensure the sterility of instruments?

   • Answer: Sterility is ensured through a multi-step process: proper cleaning and decontamination, appropriate assembly for sterilization, selection of the correct sterilization method and parameters, use of sterilization indicators and integrators to validate the process, and proper storage and handling of sterilized items to maintain sterility.

4. Explain the importance of proper instrument handling and preparation.

   • Answer: Proper handling and preparation prevents damage to instruments, ensuring their longevity and functionality. It also prevents cross-contamination and ensures effective sterilization. This includes careful disassembly, cleaning, and inspection for damage before sterilization.

5. What are the different types of sterilization indicators and what do they indicate?

   • Answer: There are chemical indicators (e.g., tape, strips) that change color indicating exposure to sterilization conditions, but not necessarily sterility. Biological indicators (spores) confirm the lethality of the sterilization cycle. Integraors combine both functions, showing both exposure to time and temperature AND biological kill.

6. How do you identify and handle malfunctioning equipment?

   • Answer: If equipment malfunctions (e.g., autoclave, washer-disinfector), I would immediately report the issue to my supervisor, document the malfunction, and follow established protocols for equipment maintenance and repair. I would also ensure that affected instruments are properly handled to prevent contamination.

7. Describe your knowledge of infection control principles.

   • Answer: I am familiar with standard precautions, hand hygiene, personal protective equipment (PPE) use, and the proper disposal of contaminated materials. I understand the importance of preventing the spread of healthcare-associated infections and adhering to all relevant infection control policies and procedures.

8. How do you maintain accurate records and documentation?

   • Answer: I maintain detailed and accurate records of all sterilization cycles, including dates, times, equipment used, sterilization parameters, and biological indicator results. I use electronic or paper-based systems as required by the facility and ensure all records are legible, complete, and readily accessible.

9. What is your understanding of the different types of sterilization wrappers and containers?

   • Answer: I understand the use of various sterilization wraps (paper, muslin, Tyvek) and rigid containers, each with its own properties and suitability for different sterilization methods and types of instruments. I know the importance of proper wrapping techniques to maintain sterility.

10. How do you handle and store sterilized items?

    • Answer: Sterilized items are handled using aseptic techniques to avoid contamination. They are stored in designated clean areas, away from dust and moisture, according to the manufacturer's recommendations and facility policies. Shelf life and expiration dates are carefully monitored.

11. What is your experience with high-level disinfection?

    • Answer: I am familiar with high-level disinfection processes and the appropriate agents used. I understand that high-level disinfection is not a substitute for sterilization and is used for items that cannot withstand sterilization methods.

12. How do you deal with a contaminated instrument or spill?

    • Answer: I would immediately clean up the spill or contaminated area using appropriate disinfectants and following established protocols. I would then report the incident to my supervisor and ensure proper disposal of contaminated materials.

13. What is your understanding of the importance of quality control in sterilization?

    • Answer: Quality control is crucial for patient safety.
