Which route involves injections into the fat layer just beneath the skin, often in the abdomen or thigh?

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

Answer: (A)

The route involves delivering medication into the fat layer just beneath the skin. This tissue lies under the skin and above the muscle, making injections here slower to absorb than into muscle or veins. It’s commonly used for medications given in small volumes and that don’t require rapid onset, such as insulin and some anticoagulants. Common sites include the abdomen and the thigh because they have ample subcutaneous fat and are easy to access. In contrast, injections into the dermis happen just under the epidermis and are used for tests like TB or allergies; injections into muscle go into the muscle tissue for faster absorption; and injections into a vein enter the bloodstream directly for immediate effect.
