Which term describes administration into a vein?

• A. Subcutaneous
• B. Intravenous
• C. After surgery
• D. L&D

Answer: (B)

The key idea is identifying how a substance enters the body. Administration into a vein is described as intravenous. Intravenous means delivery directly into the bloodstream through a vein, which allows rapid, controllable effects and quick distribution throughout the body. This contrasts with subcutaneous, which is into the tissue just beneath the skin and is absorbed more slowly. The other options aren’t routes of administration—they refer to contexts or settings (like after surgery or labor and delivery) rather than how a substance is given. So the term that specifically describes administration into a vein is intravenous.
