What is the BUD for a low-risk CSP prepared in a non-clean room environment?

  1. 12 hours (12 hours, N/A)

  2. 48 hours, 14 days, 45 days

  3. 1 hour

  4. 24 hours, 3 days, 45 days

The correct answer is: 12 hours (12 hours, N/A)

For a low-risk Compounded Sterile Preparation (CSP) prepared in a non-clean room environment, the Beyond-Use Date (BUD) is typically 12 hours. This short BUD is due to the increased likelihood of contamination when preparing sterile products in a non-clean room setting. It is important to use the CSP within this short timeframe to minimize the risk of microbial growth and ensure the product's stability and safety for the patient. The other options are incorrect because they suggest longer BUDs, which are not appropriate for low-risk CSPs prepared in non-clean room environments. Longer BUDs would pose a greater risk of contamination and compromise the sterility and efficacy of the prepared product. Therefore, option A, 12 hours, is the correct choice for a low-risk CSP prepared in a non-clean room environment.
