IM stands for which term?

• A. Intradermal.
• B. Intravenous.
• C. Intraocular.
• D. Intramuscular.

Answer: (D)

Intramuscular means injecting a medication into muscle tissue. The abbreviation IM is used to indicate this route because muscle has a good blood supply that allows the drug to be absorbed into the bloodstream from the muscle. This route is commonly used for vaccines and many medications when a slower, steadier absorption is appropriate. For contrast, intradermal goes into the skin, intravenous goes directly into a vein for rapid effect, and intraocular targets the eye.
