What is the most common site for adults to receive a subcutaneous injection?

• A. The tricep region.
• B. The abdomen.
• C. The buttock.
• D. The thigh.

Answer: (A)

Subcutaneous injections are given into the fatty tissue just under the skin, so the site is chosen to ensure enough fat, minimize muscle penetration, and provide predictable absorption. In adults, the abdomen is the preferred site because it typically has the most consistent subcutaneous fat, is easy to access, and you can rotate areas to prevent irritation. The outer upper arm (tricep region) can be used, but it often has less fat and more movement, which can make absorption more variable and injections less comfortable. Other sites like the thigh or buttock exist, but they are used less routinely. So the abdomen is the most common site for adults.
