For intradermal injections, what is the typical insertion angle and bevel orientation?

• A. 15 degrees with bevel up
• B. 5-15 degrees with bevel down
• C. 45 degrees with bevel up
• D. 90 degrees with bevel up

Answer: (B)

Intradermal injections are placed right under the epidermis into the superficial dermis, so you want a very shallow entry to keep the needle in that thin layer. A 5 to 15 degree angle keeps the tip just beneath the surface instead of diving into subcutaneous tissue or muscle, which helps you form the small wheal that indicates the solution is in the dermis. Bevel orientation matters because the way the needle tip enters the skin can influence how the liquid spreads in the dermal layer. With the bevel directed downward into the tissue, the injection tends to stay in the superficial dermis and produce that characteristic wheal. If the needle were angled more steeply or the bevel were oriented the other way, the solution is more likely to penetrate deeper or spread unevenly, reducing the accuracy of the intradermal placement.
