Expected Hemoglobin Increase After PRBC Transfusion

A patient with a hemoglobin level of 7 g/dL is scheduled to receive a transfusion of packed red blood cells (PRBCs). Each unit of PRBCs can increase the hemoglobin levels by approximately 1 g/dL in an average-sized adult. If the healthcare provider orders 2 units of PRBCs for this patient, what should be the expected hemoglobin level after the transfusion?
