If current IV fluid rate is 200 mL/hour and urine output is below 30 mL/hour, what should be the new rate according to the guideline?

If current IV fluid rate is 200 mL/hour and urine output is below 30 mL/hour, what should be the new rate according to the guideline?

• A. 250 mL/hour
• B. 200 mL/hour
• C. 150 mL/hour
• D. 300 mL/hour

Answer: (A)

Urine output reflects renal perfusion and fluid balance. When it falls below about 30 mL/hour, a modest increase in IV fluid rate is commonly used to improve kidney perfusion and raise urine output. Following this guideline, raising the current rate from 200 mL/hour by 50 mL/hour brings it to 250 mL/hour, which aims to restore adequate perfusion without jumping to a much higher rate. After increasing, monitor urine output, vital signs, and signs of fluid overload, and reassess if urine output does not improve or other issues arise.
