central sterile supply technician Interview Questions and Answers

1. What is the role of a Central Sterile Supply Department (CSSD) technician?

   • Answer: A CSSD technician is responsible for the decontamination, sterilization, and distribution of medical equipment and supplies used in a healthcare facility. This ensures that all instruments and supplies are safe and sterile for patient use, preventing infections and promoting patient safety.

2. Describe the process of instrument decontamination.

   • Answer: Decontamination involves several steps: pre-cleaning (removing gross soil), washing (using detergents and appropriate cleaning methods), rinsing, and drying. This process removes organic matter and reduces the bioburden on instruments before sterilization.

3. Explain the different sterilization methods used in CSSD.

   • Answer: Common methods include steam sterilization (autoclaving), ethylene oxide (EtO) sterilization, dry heat sterilization, plasma sterilization, and low-temperature hydrogen peroxide gas plasma sterilization. Each method has its advantages and disadvantages depending on the type of instrument and material being sterilized.

4. What are the parameters monitored during steam sterilization?

   • Answer: Critical parameters include temperature, pressure, time, and the presence of steam. Monitoring ensures that sterilization cycles achieve the required levels for effective sterilization.

5. How do you ensure the effectiveness of sterilization?

   • Answer: Effectiveness is ensured through the use of biological indicators (BIs), chemical indicators (CIs), and mechanical indicators. BIs verify sterilization lethality, CIs indicate that a sterilization cycle was run, and mechanical indicators monitor the cycle's parameters (temperature, pressure, time).

6. What are biological indicators (BIs)?

   • Answer: BIs contain a known number of resistant microorganisms (e.g., Geobacillus stearothermophilus spores for steam sterilization). Their presence and absence after the sterilization cycle verifies the lethality of the process.

7. What are chemical indicators (CIs)?

   • Answer: CIs are used to monitor physical conditions of the sterilization cycle (e.g., temperature and steam exposure). They change color to indicate that the package was exposed to the sterilization process, but they don't guarantee sterility.

8. What are the different types of packaging used for sterilized items?

   • Answer: Common packaging includes paper-plastic pouches, woven wraps, rigid containers, and peel pouches. The choice of packaging depends on the sterilization method and the item being sterilized.

9. Explain the importance of proper instrument handling and storage.

   • Answer: Proper handling prevents damage to instruments, maintains sterility, and extends their lifespan. Instruments should be handled carefully to avoid damage and stored in clean, dry areas to prevent contamination.

10. How do you identify and handle contaminated items?

    • Answer: Contaminated items should be clearly identified as such and handled with appropriate personal protective equipment (PPE), including gloves, gowns, and eye protection. They must be processed through the decontamination cycle immediately.

11. What are the safety precautions to be taken while working in CSSD?

    • Answer: Safety precautions include wearing appropriate PPE, following established procedures, handling chemicals safely, using equipment correctly, and maintaining a clean and organized work environment. Following infection control protocols is paramount.

12. What is the importance of documentation in CSSD?

    • Answer: Accurate documentation is crucial for tracking instruments, monitoring sterilization cycles, and ensuring accountability. It is also essential for tracing instruments and supplies in case of adverse events.

13. What is the role of quality control in CSSD?

    • Answer: Quality control ensures that all processes meet established standards, ensuring the sterility and safety of medical equipment and supplies. This includes regular equipment maintenance, monitoring of sterilization cycles, and adherence to infection control protocols.

14. How do you deal with a malfunctioning sterilization equipment?

    • Answer: Report the malfunction immediately to the supervisor and follow established procedures for equipment maintenance and repair. Do not use malfunctioning equipment. Any items processed during the malfunction must be reprocessed.
