1. B
The primary purpose of an SPD is to ensure patient safety by sterilizing medical instruments and maintaining a sterile environment.

2. B
Sterilized instruments should be stored in a closed, sterile storage area to maintain sterility and prevent contamination.

3. B
Biological testing ensures that the sterilization process is effective in killing microorganisms, verifying the sterilization’s success.

4. A
Instruments must be cleaned, dried, and free from organic material to ensure effective sterilization.

5. A
Monitoring temperature, pressure, and time during sterilization ensures the process is effective and consistent.

6. A
Ethylene oxide (EO) gas is commonly used to sterilize heat-sensitive items that cannot withstand high temperatures.

7. B
Teaching proper techniques and safety protocols is crucial for SPD technicians to maintain the quality and safety of sterilized instruments.

8. B
Steam sterilization is the most common method for heat and moisture-resistant instruments, as it is effective and widely available.

9. A
Biological indicators are used to ensure the sterilizer is functioning properly and that the sterilization process is effective.

10. C
The first step is to investigate the cause of the failure and correct any issues before re-sterilizing the items.

11. A
Items should be arranged to allow air circulation, ensuring even exposure to the sterilizing agent.

12. A
The sterilization record is the official document that verifies sterilization procedures have been followed.

13. A
Chemical indicators provide a visual confirmation that the sterilizing agent has reached the necessary levels to ensure sterilization.

14. A
Periodic validation ensures compliance with standards and patient safety by confirming that sterilization processes are effective.

15. A
Steam sterilization with a biological indicator is the preferred method for sterilizing rigid containers with surgical instruments.

16. A
Calibration should occur annually or according to the manufacturer’s guidelines to ensure the sterilization equipment is functioning correctly.

17. A
Improperly sterilized instruments pose a contamination risk, which can lead to infections.

18. B
Providing clear, step-by-step instructions and encouraging questions helps new technicians learn and ensure quality in sterilization procedures.

19. A
Communication is essential to ensure proper handling and delivery of sterilized items, as well as adherence to safety protocols.

20. A
Sterile items should be stored in a clean, dry, and cool environment to maintain their sterility.

21. A
Following the manufacturer’s instructions for sterilization equipment and chemicals ensures compliance with regulatory standards.

22. B
Immediate reporting of sterilizer malfunctions ensures that corrective actions are taken to prevent contamination and ensure safe operations.

23. D
The SPD technician must ensure compliance with infection control standards, including proper sterilization and documentation.

24. A
Biological indicators validate that the sterilization process has effectively killed microorganisms, ensuring the safety of sterilized items.

25. A
Flash sterilization is only used in emergency situations when instruments need to be sterilized quickly, but it should not replace traditional sterilization methods.

26. B
If a biological indicator fails, a full inspection should be conducted to identify and correct any issues before re-sterilizing the items.

27. A
Proper packaging ensures instruments remain sterile until they are needed for use, preventing contamination.

28. A
Clear written procedures and regular meetings ensure effective communication and reduce errors in the SPD.

29. A
Insufficient exposure time is a common cause of sterilization failure, as the sterilizing agent may not have had enough time to act.

30. A
The sterilizer load control system prevents overloading, ensuring that the sterilization process is efficient and effective.
