A patient is receiving 750 ml of NSS at 50 mL/hr. How many hours will the bag last?

Identify the total volume and the flow rate: Total volume: 750 mL of NSS Flow rate: 50 mL/hr Use the formula: Time (in hours) = Total Volume / Flow Rate Plug in the values and calculate: Time = 750 mL / 50 mL/hr Time = 15 hours
