A nurse practitioner orders 1 liter of 0.9% normal saline to infuse over 6 hours. How many milliliters per hour will the nurse program the IV infusion device? Round off.

To calculate the milliliters per hour (mL/hr) for the IV infusion, you divide the total volume (in milliliters) by the total time (in hours). In this case, the total volume is 1 liter, which is equal to 1000 milliliters, and the total time is 6 hours. So, you divide 1000 mL by 6 hours: 1000 mL / 6 hours = 166.67 mL/hr Rounding off, the nurse will program the IV infusion device to infuse at approximately 167 mL/hr.
