Transfusion Rate Calculation

A 52-year-old patient with a history of chronic kidney disease is scheduled to receive a unit of red blood cells (RBCs) due to severe anemia. As the nurse prepares for the transfusion, she recognizes the need to monitor the patient for transfusion reactions, specifically considering the risk of hemolytic transfusion reactions. The blood transfusion must be infused over a maximum of 4 hours, and the blood product has a volume of 300 mL.

Calculate the maximum rate of infusion (in mL/hour) that the nurse should administer to ensure the unit of blood is completed within the 4-hour timeframe. Fill in the blank below:

The maximum rate of infusion for this patient should be __________ mL/hour.
