Children with beta thalassemia major will usually require blood transfusions about every three to four weeks throughout their life. Transfusions help maintain hemoglobin at a high enough concentration to provide oxygen to the body and prevent growth abnormalities and organ damage; therefore, the nurse should monitor hemoglobin following a transfusion. A reticulocyte count is used as a diagnostic tool (to help rule out iron-deficiency anemia). Monitoring platelets would be indicated following transfusion of platelets.
