The healthcare provider prescribes 1 unit (350 mL) of packed red blood cells (PRBC) to infuse over 4 hours. The IV administration set delivers 15 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter the numeric value only. Round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["22"]

To calculate the drip rate for an IV, you can use the formula: (Volume to be infused (mL) x Drop factor (gtt/mL)) / Time (min). For the prescribed 1 unit of PRBC at 350 mL to be infused over 4 hours with a drop factor of 15 gtt/mL, the calculation would be: (350 mL x 15 gtt/mL) / (4 hours x 60 minutes/hour). This simplifies to (5250 gtt) / (240 min), which equals 21.875 gtt/min. When rounded to the nearest whole number, the nurse should regulate the infusion to 22 gtt/min.
