Which route is administered under the skin?

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

Answer: (C)

The route administered under the skin is subcutaneous. This method delivers medication into the fatty tissue just beneath the skin, where absorption is slower and more gradual compared with injections into muscle or directly into a vein. That slower absorption makes it suitable for drugs that require steady, extended effect, such as insulin or certain anticoagulants, and for vaccines that don’t need rapid onset. It’s different from intramuscular injections, which go into muscle tissue and absorb more quickly; intravenous injections go into a vein for immediate effect; and intraarticular injections go into a joint for local treatment.
