When are PRN medications administered?

PRN medications, which stand for "pro re nata" (Latin for "as needed"), are specifically administered when they are required by the resident based on their individual health needs. This administration is guided by a physician's order, ensuring that the medication is taken at appropriate times according to the patient's situation rather than on a strict schedule.

This flexibility allows for the management of symptoms or conditions that may arise intermittently. For example, a resident may require pain relief at different times depending on their level of discomfort, and the ability to use PRN medications provides that responsive care tailored to the individual.

The other options do not accurately reflect the nature of PRN medications; they imply a less individualized or non-urgent approach to medication administration.
