An IV piggyback contains 250 mL to infuse over 2 hours. What is the rate in mL/hr?

Explanation:
Infusion rate is the amount of fluid delivered per unit of time. For an IV piggyback, you find it by dividing the total volume by the infusion time in hours. Here, 250 mL is to be infused over 2 hours, so the rate is 250 ÷ 2 = 125 mL per hour. Therefore, the rate is 125 mL/hr. If you wanted a slower or faster rate, you’d adjust the time accordingly (longer time means lower mL/hr, shorter time means higher mL/hr).
