An infant weighing 16 pounds, 8 ounces is admitted to the pediatric unit with severe dehydration and requires intravenous (IV) fluid resuscitation. The nurse is preparing to administer a 0.9% normal saline IV fluid bolus of 6 mL/kg to infuse over 2 hours. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)
The Correct Answer is ["23"]
To calculate the IV fluid rate, first, convert the infant's weight from pounds and ounces to kilograms. There are 2.2 pounds in one kilogram. The infant weighs 16 pounds and 8 ounces, which is 16.5 pounds or approximately 7.5 kilograms when converted (16.5 pounds ÷ 2.2 pounds per kilogram). Next, multiply the infant's weight in kilograms by the prescribed amount of IV fluid, which is 6 mL/kg. This results in 45 mL (7.5 kg × 6 mL/kg). Since the fluid is to be infused over 2 hours, divide the total volume of 45 mL by 2 hours to find the rate per hour. The IV pump should be set to deliver approximately 22.5 mL/hr. After rounding to the nearest whole number, the IV pump should be set to deliver 23 mL/hr.
