A nurse is planning to administer a tuberculin skin test to a client who has had an exposure to tuberculosis. Which of the following actions should the nurse plan to take?

A. When administering a TST, the nurse should select an injection site that is free of scar tissue and areas with excessive hair, veins, or visible lesions. The preferred site for TST administration is the volar aspect of the forearm, approximately 2-4 inches below the elbow. B. After administering the TST, the nurse should not massage or manipulate the injection site. Massaging the site can cause irritation or spread the solution, leading to inaccurate results. C. he TST is administered intradermally, typically with a 27-gauge needle. The needle should be inserted with the bevel facing upward at a 5-15-degree angle. D. The standard dose of tuberculin solution (e.g., purified protein derivative, PPD) for a TST is 0.1 mL containing 5 tuberculin units (TU).
