A child with thalassemia major receives blood transfusions frequently. What is a complication of repeated blood transfusions?

A. Hemosiderosis: Hemosiderosis is the accumulation of iron in tissues (especially the liver, heart, and pancreas) due to frequent blood transfusions, a common treatment for thalassemia major. It can lead to organ damage if not managed with chelation therapy. B. Hematuria: Hematuria (blood in urine) is not directly linked to repeated transfusions; it may indicate kidney issues. C. Hemarthrosis: Hemarthrosis (bleeding into joints) is characteristic of hemophilia, not thalassemia. D. Hemoptysis: Hemoptysis (coughing up blood) is usually related to pulmonary conditions, not a result of transfusions.
