Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

Which factors affect the sterilization process?

1. Just temperature

2. Device cleanliness and compatibility

3. Only user error

4. Packaging and storage time

The correct answer is: Device cleanliness and compatibility

The sterilization process is influenced by multiple factors that collectively ensure the effectiveness and safety of sterilization methods. Device cleanliness and compatibility are critical elements because any residual contaminants or organic matter can hinder the sterilization process, making it less effective. Additionally, the compatibility of the device with the chosen sterilization method is vital. Not all materials can withstand the same temperatures or chemicals used in various sterilization techniques; thus, knowing the compatibility ensures that the sterilization method selected will not damage the device while still achieving the required level of sterility. Temperature, while important, is just one component of a broader set of criteria that need to be met for successful sterilization. User error and improper factors such as inadequate packaging or incorrect storage durations can also impact sterilization, but they are not the only determinants—device cleanliness and compatibility remain foundational to any successful sterilization outcome.
