Which term describes injecting into a large muscle?

• A. Intravenous administration
• B. Intramuscular administration
• C. Subcutaneous administration
• D. Oral administration

Answer: (B)

Injecting into a large muscle is called intramuscular administration. Muscle tissue has a rich blood supply, so meds given into a muscle are absorbed into the bloodstream fairly quickly—faster than injections into fatty tissue but not as fast as directly into a vein. Common sites include the deltoid in the upper arm, the gluteus maximus in the buttock, and the vastus lateralis in the thigh. This route is often used for vaccines and various medications that need a prompt effect but don’t require intravenous administration. It’s different from subcutaneous injections, which go into the fatty layer under the skin with slower absorption, and from oral administration, which must pass through the digestive system first.
