What does the abbreviation PRN refer to in medication?

The abbreviation PRN stands for "as needed" in the context of medication. This term is commonly used in healthcare settings to indicate that a medication should be administered only when required, rather than on a fixed schedule. For instance, a prescription for pain relief medication may be given with instructions for the patient to take it PRN, meaning they can take it when they are experiencing pain rather than at set intervals.

Understanding the meaning of PRN is crucial in medication management as it helps caregivers ensure that medications are given thoughtfully, allowing for responsiveness to the individual's needs and avoiding unnecessary medication administration. In contrast, the other options do not accurately define the term PRN in a medical context, making it essential for those involved in elder care to be familiar with such abbreviations to provide appropriate care.
