What does the abbreviation prn indicate in medication orders?

• A. As needed
• B. Twice daily
• C. Per rectum
• D. With meals

Answer: (A)

PRN means “as needed.” It indicates a medication should be given only when the patient shows symptoms or meets specific criteria, rather than on a fixed schedule. For example, a pain medication might be ordered PRN for moderate to severe pain, with the nurse assessing the patient and administering the dose when pain meets the criteria, up to any daily limits. This approach relies on ongoing assessments and documentation of time, dose, and reason for administration. It differs from a set schedule (like every certain number of hours) and from the other options which specify route or mealtime instructions.
