Answer to Question 1

D
A raised, reddened, or hard zone around the test site indicates a positive tuberculin skin test. An induration of 15 mm or more indicates a positive reaction in patients with no known risk factors for TB. An induration that measures 5 mm or more in diameter indicates a positive TB reaction in patients who are human immunodeficiency virus (HIV) positive, have fibrotic changes on chest radiograph consistent with previous TB infection, have had organ transplants, or are immunosuppressed. An induration of 10 mm or more indicates a positive TB reaction in patients who are recent immigrants; injection drug users; residents and employees in high-risk settings; patients with certain chronic illnesses; children younger than 4 years of age; and infants, children, and adolescents exposed to high-risk adults.
