A facility shall examine the refrigerated and non-refrigerated emergency drug supply at least every ______ and make any necessary changes at that time.

Facilities are required to examine the refrigerated and non-refrigerated emergency drug supply at least every 90 days to ensure the integrity, availability, and appropriateness of the medications. This timeframe allows for sufficient monitoring to identify any medications that may have expired, become damaged, or are no longer needed based on the facility's current patient needs.

By conducting this review every 90 days, the facility can maintain compliance with regulations and ensure the safety of its residents by having a reliable and up-to-date emergency drug supply. Regular auditing of the medication stock also assists in inventory management and helps to prevent wastage.

Other timeframes, such as 7 days, 14 days, or 61 days, are not sufficient for adequately managing the emergency drug supply, risking potential issues that could arise from expired or outdated medications. This structured approach to medication management is crucial in providing high-quality care and ensuring the well-being of the residents in the facility.
