Into what part of the body is a subcutaneous injection given?

• A. Between the skin and muscle
• B. Between layers of skin
• C. Between layers of muscle
• D. Within the abdominal cavity

Answer: (A)

Subcutaneous injections are placed into the tissue just beneath the skin, in the adipose layer that lies between the skin surface and the underlying muscle. This location preserves slower, steady absorption as the medicine sits in fat rather than in skin or muscle tissue. The other options correspond to different routes: within the layers of skin would be intradermal, within layers of muscle would be intramuscular, and within the abdominal cavity would be intraperitoneal. So the location described is precisely between the skin and the muscle.
