When a medication order includes "prn," what does it indicate?

  1. After noon

  2. Before meals

  3. Both eyes

  4. As needed

The correct answer is: As needed

When a medication order includes "prn," it indicates that the medication should be administered as needed. PRN stands for the Latin phrase "pro re nata," which means "as the situation arises" or "as needed." This type of medication order allows healthcare providers to administer the medication based on the patient's specific symptoms or condition, rather than on a strict schedule. The other options (A. After noon, B. Before meals, C. Both eyes) do not accurately describe what "prn" signifies in a medication order.
