Answer: (B)

The abbreviation 'PO' stands for "by mouth," which is derived from the Latin phrase "per os." This term is commonly used in medical settings to indicate the route by which medication or substances should be administered, particularly for oral medications. When a medication is prescribed to be taken PO, it means that the patient should ingest it orally rather than through other means such as injections or intravenously. Understanding this abbreviation is crucial for medical assistants, as it helps ensure that patients receive their medications as intended, supporting their treatment effectively. This clear designation of route of administration can significantly affect patient care and the effectiveness of the prescribed treatment.
