A medical assistant is preparing to administer a subcutaneous injection. The MA should insert the needle at which of the following angles?
- A15-degree angle
- B45-degree angle
- C90-degree angle
- D75-degree angle
Show answer & explanationAnswer & explanation
Correct answer: B. 45-degree angle
A 45-degree angle is the standard insertion angle for subcutaneous injections, especially when grasping a small amount of tissue, to ensure the medication is deposited into the subcutaneous layer.
Why the other options are wrong
- A. A 15-degree angle is typically used for intradermal injections.
- C. A 90-degree angle is used for intramuscular injections or for subcutaneous injections in patients with adequate adipose tissue using a shorter needle.
- D. A 75-degree angle is not a standard angle for common injection routes.

The angle at which a needle is inserted into the skin to deliver medication into the subcutaneous tissue layer.
- Standard angle is 45 degrees.
- Can be 90 degrees for obese patients or shorter needles.
- Aims for the fatty tissue layer beneath the dermis.
