An occupational health nurse is interpreting the results of a tuberculin skin test for a group of clients who received the test 48 hr ago. Which of the following clients should the nurse identify as having a positive test result?
A client whose injection site is scabbed is incorrect. Scabbing at the injection site does not provide information about the presence or absence of induration. It doesn't contribute to interpreting the test result directly.
A client whose injection site is firm and measures 3 mm (0.1 in) is incorrect. A measurement of 3 mm of induration is generally considered a negative result for most individuals, including those without any risk factors for tuberculosis (TB).
A client whose injection site has an elevated area measuring 15 mm (0.6 is correct. An area of induration measuring 15 mm or more is considered positive in individuals with no known risk factors for TB.
