Answer: D-The sterility assurance level refers to the probability of a microorganism remaining on an item after sterilization. When sterilizing instruments and supplies, there is always a minor chance that some small particle or microorganism may remain, even after effective sterilization. A small risk remains that a pathogen could be transmitted to another patient when supplies are used again. While the sterility assurance level measures the probability of a patient being infected, the overall rate of this transfer of microorganisms after sterilization is low.
