central sterile tech Interview Questions and Answers

1. What is the role of a Central Sterile Tech?

   • Answer: A Central Sterile Tech (CST) is responsible for the decontamination, preparation, sterilization, and distribution of medical devices and equipment used in healthcare facilities. This ensures the safety and sterility of instruments and supplies used in patient care, preventing infections.

2. Describe the process of instrument decontamination.

   • Answer: Decontamination involves removing visible soil and organic matter from instruments. This typically includes pre-cleaning (manual or automated), washing (using enzymatic detergents), rinsing, and then drying. Instruments are then prepared for sterilization.

3. What are the different types of sterilization methods used in a central sterile service department (CSSD)?

   • Answer: Common sterilization methods include steam sterilization (autoclaving), ethylene oxide (EtO) sterilization, hydrogen peroxide plasma sterilization, and dry heat sterilization. Each method is appropriate for different types of instruments and materials.

4. Explain the importance of proper sterilization techniques.

   • Answer: Proper sterilization is crucial to prevent healthcare-associated infections (HAIs). Improperly sterilized instruments can transmit pathogens, leading to serious complications or even death for patients.

5. What are the different types of sterilization indicators?

   • Answer: Sterilization indicators include chemical indicators (external and internal), biological indicators (spore tests), and electronic monitoring systems. These verify that the sterilization process has been successful.

6. How do you interpret the results of a biological indicator test?
