A nurse evaluates a client with acute glomerulonephritis (GN). Which assessment finding would the nurse recognize as a positive response to the prescribed treatment?

Rationale: A. The absence of hematuria may occur late in recovery, but it is not the earliest or most reliable indicator of improvement in acute glomerulonephritis (GN). Blood in the urine can persist even as the condition improves. B. A weight loss of 11 lb (5 kg) over 10 days indicates a reduction in fluid retention, showing that edema and fluid overload are resolving. This reflects a positive response to treatment such as diuretics, fluid restriction, or improved kidney function. Weight loss is one of the best indicators of decreasing fluid volume and successful management of GN. C. A blood pressure of 152/88 mm Hg remains elevated, suggesting continued fluid overload or renal impairment, not adequate control of the condition. D. A urine specific gravity of 1.048 is abnormally high, indicating concentrated urine and possible continued renal dysfunction or dehydration rather than improvement.
