Multiple Choice

p.o. indicates what?

Explanation:
p.o. is an administration instruction derived from the Latin per os, meaning by mouth. It’s used on prescriptions and labels to tell the clinician to give the medication by mouth to the patient. The best phrasing is “give by mouth” because it communicates the action the clinician must perform, not just the route. Saying “by mouth” or “orally” describes the route, but doesn’t specify the imperative action, and “through IV” indicates a different, intravenous route.
