A nurse is providing care to an infant diagnosed with congestive heart failure. The health care provider has prescribed digoxin 5 micrograms/kg/day Vin 2 divided doses. The infant weighs 22 pounds. How many micrograms of digoxin should the nurse administer in each dose? Round your answer to 1 decimal place

To calculate the dosage of digoxin for the infant, first convert the weight from pounds to kilograms, knowing that 1 pound is approximately 0.453592 kilograms. The infant weighs 22 pounds, which is equivalent to 22 * 0.453592 = 9.979024 kilograms. The prescribed dose is 5 micrograms per kilogram per day, so the total daily dose is 5 micrograms/kg * 9.979024 kg = 49.89512 micrograms per day. Since the medication is to be given in two divided doses, each dose should be half of the daily total. Therefore, each dose would be 49.89512 micrograms/day / 2 = 24.94756 micrograms per dose. Rounded to one decimal place, the nurse should administer 24.9 micrograms of digoxin per dose.
