What should be done when a sterilizer fails two consecutive spore tests?

When a sterilizer fails two consecutive spore tests, it is essential to prioritize patient safety and infection control practices. The correct response is to not use the sterilizer until the issue has been resolved. Spore testing is designed to ensure that sterilization processes are effective in eliminating spores from microbial pathogens. A failure in two consecutive tests indicates that the sterilizer is not functioning properly, which raises serious concerns about its ability to adequately sterilize instruments and prevent the risk of infection.

Using a sterilizer that has failed multiple tests could lead to the potential transmission of infectious diseases to patients, thereby violating safety protocols and standards. Halting the use of the malfunctioning sterilizer allows for thorough troubleshooting and repair, ensuring that it meets required sterilization standards before it is put back into operation.

While the other choices may seem reasonable at first glance, they do not adequately address the seriousness of the situation. Continuing to use the sterilizer or merely testing it again without resolving the underlying issue could result in serious health risks. Verifying the testing process is also an important step but should follow the immediate action of ceasing the use of the sterilizer until it has been checked and repaired.
