A PRN medication is administered to a resident:

A PRN medication is defined as a medication that is given "as needed." This means that it is administered based on the resident's specific needs rather than on a fixed schedule. The physician’s orders will specify the criteria for when the medication should be given, such as specific symptoms or a certain range of measurements that dictate the need for medication.

This approach allows for flexibility in managing a resident's condition while ensuring that they receive medication in a timely manner that addresses their immediate requirements. For instance, a resident may need pain medication only when they experience discomfort rather than at regular intervals throughout the day. Understanding this concept of PRN can significantly enhance personalized care and improve the wellbeing of residents.
