If urine output is below 30 mL/hour, which adjustment should be made to the IV fluid rate?

If urine output is below 30 mL/hour, which adjustment should be made to the IV fluid rate?

• A. Increase IV fluid rate by 25%
• B. Increase IV fluid rate by 50%
• C. Decrease IV fluid rate by 25%
• D. Maintain current rate

Answer: (A)

When urine output is below 30 mL/hour, the patient is not producing enough urine, which often reflects inadequate intravascular volume or poor renal perfusion. The logical step is to raise the IV fluid rate to improve circulating volume and renal blood flow, helping to boost urine production. A modest 25% increase is chosen to correct hypovolemia without risking rapid fluid overload. Apply by multiplying the current hourly rate by 1.25 (for example, 100 mL/hour becomes 125 mL/hour). After adjusting, monitor urine output over the next 1–2 hours along with vital signs and any signs of fluid overload (such as edema or respiratory changes). If urine output does not improve, reassess for other causes like renal impairment or obstruction and adjust per protocol, continuing careful monitoring.
