A nurse is monitoring a client who has dehydration and is receiving IV fluid replacement. Which of the following findings should the nurse identify as effectiveness of the treatment?

A. Increased urine output indicates improved renal perfusion and effective fluid replacement. A urine output of 200 mL over 4 hours is within the expected range for adequate hydration. B. A heart rate of 104/min is still elevated, suggesting ongoing hypovolemia or dehydration; this is not yet a sign of effective treatment. C. Urine specific gravity of 1.04 remains high, indicating concentrated urine and persistent dehydration. Effective treatment would lower urine concentration closer to normal ranges. D. Peripheral pulses of +1 indicate weak pulses and poor perfusion, which is a sign of continued dehydration, not improvement.
