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.)
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.

Correct Answer is ["9"]
Explanation
To calculate the new infusion rate in mL/hour for a prescription of 900 units/hour, one must first determine the concentration of the Heparin Sodium solution. The original concentration is 25,000 units in 250 mL, which means there are 100 units per mL. To deliver 900 units/hour, the nurse should program the infusion pump to deliver 9 mL/hour. This is because 900 units divided by the concentration of 100 units/mL equals 9 mL.
