A client is receiving isoniazid after being diagnosed with tuberculosis. Which information should the nurse include in the client's teaching plan?

Choice A reason:
Dysuria, or painful urination, is a common symptom of cystitis and indicates inflammation of the bladder, often caused by a urinary tract infection (UTI). While it is a symptom to monitor, it does not necessarily indicate progression of the infection.

Choice B reason:
An increased frequency of urination can be a symptom of cystitis due to irritation of the bladder lining. However, like dysuria, it is a common symptom of a UTI and may not signify that the infection is worsening.

Choice C reason:
Pyuria, the presence of white blood cells in the urine, and hematuria, the presence of blood in the urine, are both indicators of inflammation and infection. These symptoms can occur with cystitis but are also not specific to the progression of the infection.

Choice D reason:
Fever is a systemic response to infection and can indicate that a UTI, such as cystitis, is worsening or spreading, possibly to the kidneys, which is known as pyelonephritis. Monitoring for fever is important because it may necessitate more aggressive treatment, such as antibiotics, and possibly hospitalization if the infection is severe.

Choice A Reason
Urine negative for ketones is a normal finding and does not typically indicate an acute problem. Ketones in the urine can be a sign of uncontrolled diabetes or starvation, but their absence is expected in a well-nourished individual who is not in a state of diabetic ketoacidosis.

Choice B Reason
Sodium at 135 mg/dL and Potassium at 3.5 mEq/L are within normal ranges. The normal range for serum sodium is approximately 135-145 mEq/L, and for serum potassium, it is around 3.5-5.0 mEq/L. These values do not indicate an immediate concern for the patient with urosepsis.

Choice C Reason
A BUN of 34 mg/dL and Creatinine of 4.2 mg/dL are concerning. The normal range for BUN is approximately 6-20 mg/dL, and for Creatinine, it is about 0.6-1.2 mg/dL for males and 0.5-1.1 mg/dL for females. Elevated levels of BUN and Creatinine indicate impaired kidney function, which can be a complication of urosepsis and the nephrotoxic effects of gentamicin and vancomycin.

Choice D Reason
A white blood cell count of 12,000/mm³ is slightly elevated, which may be expected in a patient with an infection such as urosepsis. The normal range is approximately 4,500-11,000 WBCs/mm³. While this should be monitored, it does not require immediate reporting unless there is a significant change or it is outside the patient's baseline.
