A nurse is preparing to administer an intradermal tuberculin test to a client. Which of the following actions should the nurse take?

A. Advance the needle 6 mm (7 in) below the skin's surface: Intradermal injections should be administered just beneath the skin, not deeply. The needle should be inserted at an angle to form a small bleb just below the epidermis. This depth ensures proper absorption. B. Point the bevel of the needle upward prior to insertion: The bevel should be facing upward when performing an intradermal injection to ensure the medication is injected just below the skin surface. This positioning helps form a visible wheal or bleb, which is necessary for the tuberculin test. C. Administer the injection on the dorsal forearm: The recommended site for an intradermal tuberculin test is the inner aspect of the forearm, not the dorsal forearm. The inner forearm provides a flatter surface for easy visualization of the wheal. D. Insert the needle at a 20° angle to the client's skin: An intradermal injection should be administered at a 5-15° angle to ensure the needle is positioned just beneath the skin’s surface. A 20° angle may result in the injection being too deep.
