What can be used to clean the outside of a CR cassette?

Using soap and water or alcohol wipes to clean the outside of a CR cassette is acceptable, making "all of the above" the correct choice. Both soap and water effectively remove dirt and debris from the cassette's surface, maintaining its cleanliness and functionality. Alcohol wipes are also effective for sanitization and can help eliminate bacteria and viruses, providing a higher level of cleanliness.

It's important for healthcare environments to maintain high hygiene standards, especially in areas where equipment is frequently used. Cleaning the outer surfaces of CR cassettes helps prevent cross-contamination and ensures patient safety. By allowing multiple cleaning methods, the answer acknowledges the practicality of using readily available cleaning supplies while still emphasizing the importance of keeping equipment clean and safe for use.
