About this question
What does PO mean on a prescription? Medical abbreviation literacy is a core NHA CCMA Foundational Knowledge skill. Patients and exam items both ask MAs to translate short Latin-based codes into plain instructions. Read the wording and clinical context closely; those details determine the NHA CCMA competency being tested.
This question asks for the meaning of PO. PO means by mouth (per os). Common traps mix PO with PR (rectum), PV (vagina), or IM/SubQ parenteral routes. Drill frequency codes (BID, TID, QID, PRN) separately from route codes (PO, IM, IV) so you do not merge unrelated abbreviations under pressure. For what does po mean on a prescription, write the rule beside a counterexample so the distinction stays clear on later questions. Review that contrast aloud before you continue.
