The nurse needs to first determine the child's weight in kilograms by dividing 55 lb by
2.2 or 55 / 2.2 = 25. Then the nurse should multiply the prescribed dose of 0.15 mg by the child's weight or 0.15 mg × 25 kg = 3.75. After rounding, the nurse should provide the patient with 3.8 mg of the medication prior to receiving chemotherapy.
