Section 6 Answers:

26. Chemical indicators: These are primarily used to monitor the physical parameters of the sterilization cycle (e.g., temperature and pressure). They change color to indicate that the instrument has been exposed to the sterilization process, but they do not guarantee sterility. Biological indicators: These use Bacillus stearothermophilus spores to directly test the effectiveness of the sterilization process by determining if all microorganisms have been killed. Both are essential; chemical indicators provide a first-line check, while biological indicators confirm the sterilization process's lethality.

27. Meticulous record-keeping is crucial for tracking sterilization cycles, ensuring instrument history, demonstrating compliance with regulatory standards, and facilitating traceability in case of infection concerns. Sterilization logs should include the date and time of the cycle, the sterilizer used, the type of load (instruments, textiles, etc.), the cycle parameters (temperature, pressure, time), the type of sterilization indicators used (chemical and biological), the results of the indicators, and the initials or identification number of the personnel who performed the sterilization. This comprehensive approach to documentation is critical for ensuring patient safety and regulatory compliance. Any deviations from established procedures should be carefully documented, along with any corrective actions taken.

28. A failed biological indicator indicates that the sterilization process was not effective and potentially harmful to patients. Immediate action is required. This includes: immediately removing the affected instruments from the surgical suite, conducting a thorough investigation to identify the cause of the failure (e.g., malfunctioning equipment, incorrect cycle parameters, improper loading), re-sterilizing the instruments using appropriate methods, and reporting the incident to appropriate authorities. This also requires a review of all previously sterilized instruments within a specific timeframe, depending on the severity of the failure. Documentation of the entire process, including corrective actions and preventative measures to avoid future failures, is crucial.

This practice test provides a solid foundation for your SPT certification preparation. Remember to review any areas where you struggled and continue to study all aspects of sterile processing techniques. Good luck with your exam!
