First, convert the child's weight from pounds to kilograms (1 lb = 0.453592 kg). The child weighs 84 lbs, which is approximately 38.1 kg (84 lb * 0.453592 kg/lb). The prescribed dose is 35 mg/kg per day. Therefore, the daily dose is 38.1 kg * 35 mg/kg = 1333.5 mg, which is approximately 1.3 grams (g).
