Which term describes injecting into the fatty layer under the skin?

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

Answer: (C)

Injecting into the fatty layer under the skin targets the subcutaneous tissue, so the term is subcutaneous administration. This route places medication into the adipose tissue just beneath the skin, using a short, fine needle. Absorption from this tissue is relatively slow compared with muscle because the blood supply is less abundant, which is why subcutaneous injections are often used for drugs designed for gradual absorption. By contrast, oral administration involves the digestive system, intravenous administration goes directly into a vein, and intramuscular administration delivers medicine into muscle tissue, which has a richer blood supply and typically faster absorption.
