Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

At which point can sterilized items potentially become contaminated?

1. During initial assembly

2. Only during storage

3. Any time during handling, transport, or storage

4. Immediately after sterilization

The correct answer is: Any time during handling, transport, or storage

Sterilized items can potentially become contaminated at any time during handling, transport, or storage due to various factors. Contamination can occur if the items are touched by unclean hands, come into contact with contaminated surfaces, or are exposed to airborne pathogens. Handling involves the direct interaction with the items, which poses the risk of introducing contaminants. Additionally, transport of sterilized items, whether within a facility or to another location, can bring exposure to environmental factors that might compromise their sterility. Storage is another critical phase; if sterilized items are not stored properly—such as in unsealed containers or in areas with high foot traffic—they can be easily contaminated. This understanding underscores the importance of maintaining strict protocols not only during the sterilization process but throughout the entire lifecycle of sterilized items, from their preparation to their eventual use. In comparison, while initial assembly and immediately post-sterilization stages carry some risk, the broader context of handling and transport encompasses a wider range of potential contamination scenarios.
