Under HIGH RISK conditions, refrigerated preparations can be stored for how many days?

• A. 1 day
• B. 5 days
• C. 3 days
• D. 7 days

Answer: (C)

Beyond-use dating for sterile preparations depends on the risk level and where they’re stored. Under high-risk conditions, refrigerated preparations have a three-day beyond-use date. This shorter window reflects the greater chance of contamination or endotoxin issues when sterility isn’t guaranteed, so chilling the product slows growth but doesn’t allow a long storage time. So, if you prepare a high-risk CSP and keep it in the refrigerator, you’d generally have up to three days to use it.
