An adult has active tuberculosis, as diagnosed by sputum examination and culture. In evaluating the patient's response to therapy, the nurse would want to see which finding?
a. Improved x-ray report within 3 months
b. Absence of symptoms by 8 weeks
c. Return to a negative skin test by 4 weeks
d. Negative computed tomography (CT) scan by 2 weeks
ANS: A
The nurse would expect to see an improved x-ray report within 3 months. Therapy is evaluated in three ways: bacteriologic evaluation of the sputum, clinical evaluation, and chest radiographs.
The nurse would not expect symptoms to be absent or a negative TB skin test. The patient will always have a positive test result, because antibodies are in the system.
A CT scan is not indicated.
