The antitubercular drug isoniazid is prescribed for a client with active tuberculosis. To evaluate the effectiveness of this medication, which outcome can the nurse expect this client to exhibit?
Decreased cough and sputum.
A positive sputum smear and culture.
Decreased appetite and weight loss.
Vertigo and tinnitus.
The Correct Answer is A
Choice A rationale
Isoniazid is an antitubercular drug used to treat active tuberculosis. The effectiveness of this medication is evaluated by observing a decrease in symptoms such as cough and sputum production. This indicates that the infection is being controlled and the bacteria are being eradicated.
Choice B rationale
A positive sputum smear and culture would indicate the presence of active tuberculosis bacteria, suggesting that the treatment is not effective. Therefore, this is not an expected outcome of effective treatment.
Choice C rationale
Decreased appetite and weight loss are not indicators of the effectiveness of tuberculosis treatment. In fact, these symptoms could indicate a worsening of the condition or side effects of the medication.
Choice D rationale
Vertigo and tinnitus are not related to the effectiveness of tuberculosis treatment. These symptoms could be side effects of the medication but do not indicate the success of the treatment.

Choice A rationale
