1. PO medications are given orally.
2. PO medications are given rectally.
3. PO medications are given intramuscularly.
4. PO medications are given vaginally.
Correct Answer: 1
Rationale 1: PO is the medical abbreviation for by mouth (oral).
Rationale 2: Rectal is incorrect because PO is the medical abbreviation for by mouth (oral).
Rationale 3: Intramuscular is incorrect because PO is the medical abbreviation for by mouth (oral). The abbreviation for intramuscular is IM.
