If your chart outlines a medication dosage marked "PRN," how often should the nurse administer it?
Explanation
Derived from the Latin *Pro Re Nata*, "PRN" means "as circumstances require" or "as needed." This medication (often pain relief, sleeping aids, or anti-nausea drugs) is only given if you specifically ask for it or show symptoms, up to a safe limit.
