After kidney removal, which practice best supports fluid balance monitoring?

• A. Monitor fluid balance by measuring urine output and body weight
• B. Check daily vitamin levels
• C. Monitor only blood pressure
• D. Assess appetite every shift

Answer: (A)

After kidney removal, the remaining kidney must keep fluid and electrolyte balance, so the most useful monitoring is tracking how the body handles fluids in real time. Measuring urine output and daily body weight gives direct, timely insight into fluid status. Urine output reflects how well the kidney is producing urine and indicates perfusion and hydration; a drop can signal dehydration or reduced kidney function, while a rise can point to diuresis or fluid shifts. Daily weight changes show net fluid gain or loss, and when measured consistently at the same time with similar clothing, small shifts become meaningful trends. Together, they provide a practical, ongoing picture of fluid balance and guide fluid management effectively.

Vitamins don’t reveal hydration status, blood pressure alone can be influenced by many factors and may not track immediate fluid shifts, and appetite isn’t a reliable proxy for fluid balance.
