How are intradermal injections administered?

How are intradermal injections administered?

• A. Directly into the skin and under the dermis at a shallow angle.
• B. Directly below the skin bevel up at approx 15 degrees, inject the fluid slowly.
• C. Into the subcutaneous tissue at 45 degrees.
• D. Into a vein with a rapid push.

Answer: (B)

Intradermal injections are delivered into the dermal layer, just beneath the epidermis. The needle is inserted at a very shallow angle with the bevel facing upward so the fluid stays mainly in the dermis and a tiny raised wheal forms. Injecting slowly helps you control the amount and depth, preventing the needle from going deeper than intended. This technique differs from subcutaneous injections, which go into the fat layer at a steeper angle (about 45 degrees), and from intravenous injections, which are given into a vein and usually involve a rapid push. The option describing bevel up at a shallow angle and slow injection best matches how intradermal shots are performed.
