A client receives a prescription for 1 L of lactated Ringer's IV to be infused over 12 hours. The IV administration set delivers 15 gtt/mL. How many gft/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

To calculate the flow rate for an IV infusion, you can use the formula: (Volume in mL / Time in minutes) * Drop factor (gtt/mL) = Flow rate (gtt/min). For a prescription of 1 L (which is 1000 mL) of lactated Ringer's to be infused over 12 hours (which is 720 minutes), and an IV administration set that delivers 15 gtt/mL, the calculation would be: (1000 mL / 720 minutes) * 15 gtt/mL = 20.83, which rounds to 21 gtt/min.
