In the immediate postpartum period, an IV infusion rate of 125 mL/hour may contribute to which physiologic change?

• A. It contributes to diuresis
• B. It increases infection risk
• C. It reduces urine output
• D. It has no effect on urinary function

Answer: (A)

In the immediate postpartum period, the body begins shedding the extra fluid accumulated during pregnancy through increased urine production—diuresis. Providing IV fluids at 125 mL/hour adds to the circulating volume and boosts kidney perfusion, which promotes urine formation. That combination makes diuresis the most likely physiologic change you’d see with that IV rate. This rate doesn’t inherently raise infection risk, nor would it reduce urine output or have no effect on urinary function—the expected effect is increased urine production as part of the normal postpartum fluid clearance.
