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. Inject 0.3 to 0.5 mL of the solution: The typical volume for a tuberculin skin test is 0.1 mL. B. Select an injection site that is free of scar tissue: Scar tissue can interfere with the reading of the tuberculin skin test, so a site free of scars should be selected. C. Hold the needle at a 30° angle during injection: The needle should be held at a 5–15° angle for intradermal injections. D. Massage the site following the injection: Massaging the site is not recommended as it could affect the accuracy of the test.
