Intradermal administration is delivered where?

Intradermal administration is delivered where?

• A. Just under the outer layer of the skin (tuberculosis test)
• B. Into the muscle
• C. Under the armpit area
• D. Into a vein

Answer: (A)

Intradermal administration delivers the injection into the dermis, the layer of skin just beneath the outermost epidermis. This shallow, immune-rich layer is why the TB skin test is given intradermally—it places the antigen where immune cells can quickly respond, producing the characteristic small wheal at the injection site. The volume is small, and the goal is to create that tiny raised bump rather than deliver medicine into muscle or a vein. It’s not into muscle (that would be intramuscular) and not into a vein (that would be intravenous), and the location described for this route is specifically within the skin rather than under the armpit or other areas.
