What angle is used when giving a subcutaneous injection?

• A. 0 degrees.
• B. 15 degrees.
• C. 45 degrees.
• D. Bevel up at a 45 degree angle.

Answer: (D)

When giving a subcutaneous injection, the goal is to place the medication into the fatty tissue just beneath the skin. Inserting the needle at a 45-degree angle helps keep the tip in the subcutaneous layer rather than reaching muscle or staying too shallow. Having the bevel facing up as you enter the tissue allows the skin to part smoothly along the bevel edge, reducing tissue trauma and promoting a gentler, more controlled entry. A very shallow angle like 0 or 15 degrees wouldn’t reliably reach the subcutaneous tissue, while a perpendicular 90-degree angle increases the chance of penetrating muscle in many adults. So, bevel up at a 45-degree angle is the most appropriate technique for subcutaneous injections.
