Medical Device Reprocessing Association of Ontario (MDRAO) Practice Exam

For flexible scopes, how often must brushes used be cleaned and disinfected?

1. Once a week

2. After every use

3. At the end of the work shift

4. Only when visibly dirty

The correct answer is: At the end of the work shift

Cleaning and disinfecting brushes used for flexible scopes at the end of the work shift is based on maintaining a high standard of infection control. It ensures that any potentially contaminating materials are adequately managed. Brushes can harbor biofilm and other pathogens if not appropriately cared for, and while it might seem practical to clean them after each use or when visibly dirty, there may be instances where brushes could still be contaminated by indirect contact or improper handling. By instituting a policy of cleaning and disinfecting at the end of each work shift, the process can be systematically completed, allowing for thorough cleaning and disinfection protocols to be performed without risk of cross-contamination between different procedures. Following this guideline helps ensure that all tools are ready for use the next day, thereby enhancing patient safety and the overall effectiveness of the reprocessing cycle for flexible scopes.
