Question

A nurse is preparing to administer lactated Ringer's solution 25 mL/kg to infuse over 12 hr to a toddler who weighs 14 kg. The nurse should set the IV pump to deliver how many mL/hr?

Answer 1

To calculate the IV pump rate, multiply the dosage of 25 mL/kg by the patient's weight of 14 kg, resulting in a total volume of 350 mL. Then, divide this by the infusion time of 12 hours to get the rate of 29.17 mL/hr.

Step-by-step explanation:

To calculate the infusion rate in mL/hr for a lactated Ringer's solution for a toddler weighing 14 kg, with a prescription of 25 mL/kg to be infused over 12 hours, we first calculate the total volume of lactated Ringer's solution needed:

• 25 mL/kg × 14 kg = 350 mL (total volume)

Then we divide the total volume by the number of hours over which the infusion is to be administered:

• 350 mL ÷ 12 hours = 29.17 mL/hr

The IV pump should be set to deliver 29.17 mL/hr of lactated Ringer's solution.
