The child weighs 55 lb. To determine weight in kilogram, divide 55 lb by 2.2 = 25 kg. Then multiply the weight in kg by 15 ml to determine the total amount of blood the patient is to receive or 15 ml × 25 kg = 375 ml. Then to determine the amount of blood to infuse per hour, multiply 10 ml × 25 kg = 10 × 25 = 250 ml. If the child is to receive a total of 375 ml of blood, divide 375 ml by 250 ml to determine that the prescribed amount of blood will take 1.5 hours to infuse.
