In CKD, what daily fluid intake guideline is often used for patients with edema or oliguria?

• A. 1,000-2,000 mL/day plus urine output
• B. 2,500-3,000 mL/day
• C. Fluid unrestricted
• D. 500-1,000 mL/day

Answer: (A)

In CKD with edema or oliguria, the goal is to prevent fluid overload while staying hydrated, because the kidneys can’t excrete water effectively. A practical way to do this is to set a fluid allowance that combines a fixed baseline with what the kidneys still manage to excrete as urine.

The guideline used is a daily fluid allowance of 1,000 to 2,000 mL plus urine output. This means you plan total fluid intake to be that baseline range plus whatever the patient urinates in a day. If urine output is 600 mL, the target intake would be about 1,600 to 2,600 mL for that day. If urine output is only 100 mL, the target would be about 1,100 to 2,100 mL. This approach tailors fluid restriction to the person’s remaining kidney function and helps prevent edema and fluid overload.

Keep in mind to monitor weight, edema, blood pressure, and daily urine output to adjust as needed.
