What does the abbreviation "prn" or "PRN" stand for in medication instructions?

1. At a specific time

2. As needed

3. Every day

4. Before meals

The correct answer is: As needed

The abbreviation "prn," derived from the Latin phrase "pro re nata," translates to "as needed." This term is commonly used in medical contexts to indicate that a medication may be administered when necessary, rather than at scheduled intervals. For instance, a patient might be prescribed a pain reliever to take prn; they would take it only when they experience pain rather than adhering to a strict timetable. This flexibility is crucial for managing symptoms without overmedicating or taking medications unnecessarily. The other options refer to specific timing or conditions for medication administration. For example, "at a specific time" suggests a fixed schedule, "every day" indicates a regular daily dosage, and "before meals" specifies a timing relative to meals, none of which align with the primary meaning of "prn." Understanding this abbreviation helps ensure medications are used appropriately based on patients' individual needs and circumstances.
