PRN stands for which of the following?

• A. As needed, whenever necessary
• B. Medication Administration Records
• C. Controlled Substances Act of 1970
• D. Absorption, Distribution, Metabolism, Excretion

Answer: (A)

PRN means pro re nata, Latin for "as needed." This indicates a medication is given when the patient requires it rather than on a fixed schedule. In practice, you’d verify there’s a PRN order, assess the patient’s need (for example, level of pain or nausea), consider safety and dosing limits, administer if appropriate, and document the effect. The other options refer to records, a law regulating controlled substances, or the body’s drug-processing steps, none of which describe how the medication is scheduled. So the correct interpretation is "as needed, whenever necessary."
