PO, in medical shorthand, means

Explanation:
PO indicates the medication should be taken by mouth. It comes from the Latin "per os," meaning through the mouth, so the drug is swallowed and absorbed via the gastrointestinal tract. This oral route is common because it’s convenient and noninvasive. In contrast, intravenous is delivered directly into a vein, rectal administration enters through the rectum, and inhalation means the drug is breathed into the lungs. So the correct interpretation of PO is by mouth.
