Where are subcutaneous injections given?

• A. In the deep muscle tissue.
• B. In the bone.
• C. In the vein.
• D. In the loose connective/fatty tissue between the skin and muscle.

Answer: (D)

Subcutaneous injections are given into the loose connective tissue and fat just beneath the skin. This layer sits between the skin and the underlying muscle and acts as a cushion with limited blood vessels, which allows medications to be absorbed more slowly and steadily than when placed into muscle. If you were to inject into the deep muscle tissue, it would be an intramuscular injection, which absorbs more quickly and has different considerations. Injecting into the bone isn’t appropriate—bone is not a tissue where injections are given. Injecting into a vein would be an intravenous route, which is for direct entry into the bloodstream and not used for subcutaneous dosing.
