A 6-year-old is diagnosed with growth hormone defi ciency. A prescription is written for a dose of 0.025 mg/kg of somatotropin subcutaneously three times weekly. The child weighs 59.4 lb. Which dose of medication should the nurse administer three times weekly?

ExplanationFirst change the weight in pounds to kilograms by dividing the pounds by 2.2: 59.4 ÷ 2.2 = 27 kg. Determine the dosage of medication by multiplying 27 kg by the medication prescribed at 0.025 mg/kg. The total dosage needed is 0.675 mg.
