When a nurse interprets a prescription as PRN, what does it mean?

The interpretation of a prescription as PRN stands for "pro re nata," which is a Latin phrase meaning "as needed" or "as the situation arises." This indicates that the medication should be given only when the patient requires it, rather than on a fixed schedule. For instance, a pain medication might be ordered PRN, meaning the patient should receive it only when they report pain, rather than taking it at set times throughout the day.

This allows for flexibility in treatment and ensures that medication is administered based on the patient's specific needs rather than adhering to a strict dosing regimen. Being acquainted with the PRN requirement is essential for nurses to provide patient-centered care and to manage medications effectively.`
