A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation & Rationale
To calculate the dose of somatropin to be administered per dose, we first need to convert the child's weight from pounds to kilograms. We can do this using the following conversion factor: 1 kg = 2.2 lbs Therefore, the child's weight in kilograms is: weight_kg = 66 lbs / 2.2 lbs/kg = 30 kg Next, we can calculate the total dose of somatropin to be administered per week using the following formula: total_dose = weight_kg * 0.24 mg/kg/week This gives us a total dose of: total_dose = 30 kg * 0.24 mg/kg/week = 7.2 mg/week Finally, we can calculate the dose of somatropin to be administered per dose by dividing the total dose by the number of daily doses: dose_per_dose = total_dose / 6 doses/day = 1.2 mg/dose Therefore, the nurse should administer 1.2 mg of somatropin per dose. Answer: 1.2 mg of somatropin per dose.
