California Registered Dental Assistant (RDA) Written Practice Exam

To reduce the contamination of cleaning solutions, what does the CDC recommend for reusable mops used on housekeeping surfaces?

1. Use disposable mops only

2. Soak in a strong disinfectant after every use

3. Cleaned and dried before reuse

4. Replace them after each use

The correct answer is: Cleaned and dried before reuse

The options A, B, and D are not recommended by the CDC as they either generate more waste or are not an effective way to reduce contamination. Using disposable mops only creates unnecessary waste and replacing them after each use can be expensive. Soaking in a strong disinfectant after every use may not be sufficient enough to eliminate all contamination. Cleaning and drying the reusable mops before reuse is the recommended method by the CDC to effectively reduce contamination without generating more waste.
