A male client is asking the nurse a question regarding the Mantoux test for tuberculosis. The nurse should base her response on the fact that the:
a. Area of redness is measured in 3 days and determines whether tuberculosis is present.
b. Skin test doesn’t differentiate between active and dormant tuberculosis infection.
c. Presence of a wheal at the injection site in 2 days indicates active tuberculosis.
d. Test stimulates a reddened response in some clients and requires a second test in 3 months.
Answer B.
The Mantoux test doesn’t differentiate between active and dormant infections. If a positive reaction occurs, a sputum smear and culture as well as a chest X-ray are necessary to provide more information. Although the area of redness is measured in 3 days, a second test may be needed; neither test indicates that tuberculosis is active. In the Mantoux test, an induration 5 to 9 mm in diameter indicates a borderline reaction; a larger induration indicates a positive reaction. The presence of a wheal within 2 days doesn’t indicate active tuberculosis.
