Sample Question
A biological indicator (BI) test comes back positive after a steam sterilization cycle. What is the FIRST action the technician should take?
Explanation:
A positive BI means live spores survived the sterilization cycle — this is a critical failure. The immediate response is to quarantine all items processed in that load to prevent use of potentially non-sterile items on patients, then notify the supervisor for further investigation. Re-testing alone is not sufficient as a first step.
