The abbreviation "PO" stands for "per os," which is a Latin term meaning "by mouth." This term is commonly used in veterinary medicine, as well as in human medicine, to indicate that a medication should be administered orally. When a medication is given PO, it is taken through the gastrointestinal tract, starting from the mouth, which is a standard route for many medications intended for systemic effects.

Understanding this abbreviation is crucial for accurate medication administration in veterinary practice, as it clarifies how the medication should be administered to ensure proper absorption and effectiveness. This differentiation is particularly important in a clinical setting where other routes of administration, such as intravenous (IV) or subcutaneous (SQ), may be used.

The other options do not accurately reflect the meaning of "PO":

- "Post operation" pertains to a time frame rather than a method of medication administration.

- "Prior observation" does not relate to any specific route and is not a term used for medication dosing.

- "Patient order" does not specifically indicate how the medication is to be given and could pertain to various instructions unrelated to administration methods.

Thus, the correct understanding of "PO" as "by mouth" is fundamental in ensuring that medications are given correctly in veterinary practice.
