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?
Inject 0.3 to 0.5 mL of the solution.
Select an injection site that is free of scar tissue.
Hold the needle at a 30° angle during injection.
Massage the site following the injection.
The Correct Answer is B
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.

Correct Answer is A
Explanation
A. "Take the medication on an empty stomach.": Rifampin is most effective when taken on an empty stomach to ensure better absorption.
B. "Discontinue the medication if your saliva turns orange.": This is a common side effect of rifampin, and the medication should not be discontinued due to this harmless effect.
C. "Return for another TB skin test in 3 months.": Follow-up skin tests are not necessary if the client is already undergoing treatment. The focus should be on medication adherence.
D. "You will need to take this medication for 1 week.": Rifampin is typically taken for several months (usually 6-9 months) to fully treat TB, not just for one week.
Correct Answer is ["0.85"]
Explanation
Volume to administer = Prescribed dose/ available concentration
= 17, 000 units/20, 000 units/mL
= 0.85 mL
