"I should drink 2,500 mL/day of fluid." In healthy adults, fluid intake generally averages approximately 2,500 mL/day, but it can range from 1,800 to 3,000 mL/day with a similar volume of fluid loss.

A health care provider writes a prescription to "force fluids." What will be the first action the nurse will take in implementing this prescription?
