Show answer & explanationAnswer & explanation
Correct answer: D. Discard the solution, clean the container, and prepare a fresh batch.
Cloudiness or visible debris in a disinfectant solution indicates contamination or depletion of its active ingredients, rendering it ineffective. It must be discarded and replaced to ensure proper disinfection.
Why the other options are wrong
- A. Filtering debris does not restore disinfectant efficacy or remove microbial contamination.
- B. The entire solution is compromised; using the 'clear' part is still using an ineffective disinfectant.
- C. Adding more concentrate may not restore efficacy and can create an improperly mixed, potentially dangerous solution.
