A nurse is preparing to administer digoxin 7.5 mcg/kg/day PO daily to a school-age child who weighs 52 lb. Available is digoxin elixir 50 mcg/mL. How many mL 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.)

Identify the given information: Dose of digoxin: 7.5 mcg/kg/day Weight of the child: 52 lb Concentration of digoxin elixir: 50 mcg/mL Convert the child's weight from pounds to kilograms: 1 lb ≈ 0.453592 kg Calculate the total daily dose of digoxin in mcg: Total daily dose = Dose/kg/day x Weight (kg) Substitute the values: Total daily dose = 7.5 mcg/kg/day x 52 lb x (0.453592 kg/1 lb) Total daily dose ≈ 177.56 mcg Calculate the dose per dose (every 24 hours): Dose per dose = Total daily dose / 1 Substitute the values: Dose per dose = 177.56 mcg / 1 Dose per dose ≈ 177.56 mcg Calculate the volume of digoxin elixir to be administered: Volume = Dose per dose (mcg) / Concentration (mcg/mL) Substitute the values: Volume = 177.56 mcg / 50 mcg/mL Volume ≈ 3.55 mL Round the answer to the nearest tenth: Volume ≈ 3.5 mL
