What does the abbreviation PO stand for in medication administration?

The abbreviation "PO" stands for "Per Oral," which indicates that a medication is to be taken by mouth. This route of administration is one of the most common for various medications, as it is convenient and often preferred by patients. Medications taken orally can come in various forms such as tablets, capsules, liquids, and suspensions.

Understanding this term is critical for medication administration in a healthcare setting, as it directly influences how a medication is given to the patient and, consequently, its effectiveness. Knowledge of such abbreviations helps medication aides avoid errors in medication delivery, ensuring that patients receive their medications in the proper way, leading to the desired therapeutic effects.

Other common interpretations for medical abbreviations include "Patient Order," "Post Operation," and "Preoperative," but they do not align with the established terminology used for routes of administration like "Per Oral." This distinction is essential for ensuring clear communication among healthcare providers regarding patient care and medication delivery.
