A patient with a 2 L IV bag running at 20 drops per mL at a rate of 15 drops per minute is delivering how many mL per hour?

Explanation:
Understanding IV flow rate is about converting the drip rate to volume using the drip factor. With a drop factor of 20 drops per milliliter, 15 drops per minute equals 15/20 = 0.75 mL per minute. Multiply by 60 minutes to get per hour: 0.75 × 60 = 45 mL/hour. The 2-liter bag size isn’t needed for this calculation; it would tell you how long the bag lasts at this rate. So, the patient is receiving 45 mL per hour.
