The nurse is reading the results of a tuberculin skin test (see fi gure). The nurse should interpret the results as:
- A. Negative
- B. Needing to be repeated.
- C. Positive.
- D. False.
Correct Answer: C
Rationale: The tuberculin test is positive. The test should be interpreted 2 to 3 days after administering the purifi ed protein derivative (PPD) by measuring the size of the fi rm, raised area (induration). Positive responses indicate that the client may have been exposed to the tuberculosis bacteria. A negative response is indicated by the absence of a fi rm, raised area, or an area that is less than 5 mm in diameter. Since the test is positive, it is not necessary to redo the test. The test is positive, not false.
