The health care provider prescribes 0.2 mg/kg every 4 hours for the pediatric client who weighs 35 pounds. The medication is mixed 10 mg per 1 mL
How many mL of medication would the nurse administer for each dose?
____ mL
Record answer rounding to the nearest hundredth.
Correct Answer: 0.32
This is a multistep problem. First, the nurse calculates the child's weight in kilograms by dividing 35 pounds by 2.2 because 2.2 kg = 1 pound. The child's weight in kg is 15.91. 0.2 mg is to be given for every kg of body weight, so to determine the proper dosage, multiply 0.2 X 15.91 = 3.182 mg or 3.2 mg. The medication is supplied with 10 mg in every 1 mL. Using the ratio method, 10 mg:1 mL = 3.2 mg: x, 10 X x = 1 X 3.2. Divide both sides by 10: 10x ÷ 10 = 3.2 ÷ 10 or x = 0.32.
