Calculate Blood Transfusion Rate

A patient with chronic kidney disease is undergoing a transfusion of packed red blood cells (PRBCs) due to significant anemia. The nurse is aware that the total volume of PRBCs is 300 mL and that the transfusion should be administered over a duration of 4 hours. To ensure patient safety and proper monitoring, the nurse calculates the required hourly infusion rate for the PRBCs. The nurse determines that the infusion rate should be _____ mL/hr.
