Which route is abbreviated as PO?

Explanation:
PO indicates administration by mouth, taken orally. It comes from per os, Latin for “by mouth,” and is used to specify that a medication should be swallowed rather than given by another route. The other options refer to different routes: intramuscular is given into muscle (IM), parenteral covers routes outside the GI tract (like IV, IM, subcutaneous), and enteral meds include any meds delivered into the GI tract (which includes oral, but PO is the precise oral form). So the abbreviation PO aligns with oral administration.
