What is the recommended practice for disposing of prep solution after use?

• A. Pour into patient.
• B. Reuse for next patient.
• C. Dispose immediately in waste can with no drying.
• D. Allow to dry and evaporate; dispose of any waste according to facility policy, ensuring no pooling or spillage.

Answer: (D)

The principle being tested is safe and proper disposal of skin prep after use. Let the prep solution dry on the skin so its antimicrobial action can complete and there is no excess liquid that could drip or pool. Once it has dried, dispose of any remaining waste according to your facility’s policy, which governs chemical handling and hazardous waste to protect patients and staff. This approach also minimizes the risk of cross-contamination and environmental release.

Pouring prep into a patient is dangerous and inappropriate, as is reusing prep for another patient due to cross-contamination risks. Disposing immediately without allowing drying can lead to spills or splashes and may not align with how the solution is intended to be handled or regulated.
