Answer: B - The rate required to deliver 5 mg of morphine per hour is 300 drops per hour. If the morphine IV bag has 100 mg in 100 mL of D5W, then each mL in the bag contains 1 mg of morphine. If a patient needs 5mg per hour, they need 5mL per hour, and since the IV set delivers 60 drops per mL, 5 x 60 = 300 drops per hour.
