A nurse is preparing to administer digoxin oral solution 8 mcg/kg/day PO in two equally divided doses to a toddler who weighs 10 kg (22 lb). The amount available is digoxin 0.05 mg/mL. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
