A 1000 mL IV bag is to be infused over 24 hours. What is the rate in mL/hr?

Explanation:
The main idea is to convert total volume into a rate by dividing by the time. Rate = volume / time. Here, 1000 mL over 24 hours gives 1000 ÷ 24 = 41.666... mL per hour. Rounding to one decimal place yields 41.7 mL/hr. If you used 50 mL/hr, you’d deliver 1200 mL in 24 hours; at 83 mL/hr you’d deliver about 1992 mL; at 33 mL/hr you’d deliver about 792 mL. So 41.7 mL/hr matches delivering the full 1000 mL in 24 hours.
