What is the route of administration for a drug prescribed to be given ID?

• A. Intravenous
• B. Intramuscular
• C. Subcutaneous
• D. Intradermal

Answer: (D)

ID, or intradermal, means injecting the drug into the dermal layer of the skin, just beneath the outer epidermis. This route is used when very small volumes are needed and when the test response is observed in the skin, such as tuberculin or allergy skin tests. The injection is given with a shallow angle so the solution stays in the dermis, typically forming a small wheal. This differs from intravenous injections into a vein, intramuscular injections into muscle, and subcutaneous injections into the fatty tissue under the skin, each with different absorption rates and common uses.
