A nurse is preparing to administer calcitonin 8 units/kg IM to a client who weighs 165 lb. Available is 200 units/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the dose of calcitonin for a client who weighs 165 lb, the nurse needs to convert the weight to kilograms first. One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 165 / 2.2 = 75 kg. The prescribed dose is 8 units/kg, so the total dose is 8 x 75 = 600 units. The available concentration is 200 units/mL, so the volume to administer is 600 / 200 = 3 mL. The nurse should administer 3 mL of calcitonin IM to the client.
