A client has a positive sputum culture for Mycobacterium tuberculosis and is prescribed streptomycin as part of the treatment. The nurse determines that the client is experiencing a toxic effect of the medication when which test result is abnormal?
- A. Vision testing
- B. Hepatic enzymes
- C. Hemoglobin and hematocrit
- D. Blood urea nitrogen (BUN) and creatinine
Correct Answer: D

The client taking isoniazid for tuberculosis is at risk for hepatotoxicity. Hemoglobin and hematocrit are not specifically related to tuberculosis.
