Use the equivalent: 1 kg = 2.2 lb. Convert pounds to kilograms by dividing the number of pounds by 2.2: 54/2.2 = 24.545 kg. Round to the nearest hundredth (24.55). Determine the safe dosage range. The literature states the recommended daily dosage range is 40 mg/kg/day, divided into four equal doses, not to exceed 2 g/day. Therefore, the child's safe daily dosage is 981.6 mg (24.54 kg *40 mg). The physician ordered 25 mg/kg/day. Therefore, 24.55 kg * 25 mg = 613.75 mg/day, which is safe to give.
