A child who has Beta-Thalassemia is receiving numerous blood transfusions. The child is also receiving deforaxamine (Desferal) therapy. The parents ask how the deforaxamine will help their child. The nurse explains that the deforaxamine is given to
1. prevent blood-transfusion reactions.
2. stimulate red-blood-cell production.
3. provide vitamin supplementation.
4. prevent iron overload.
Answer:4
Rationale:Iron overload can be a side effect of a hypertransfusion therapy. Deforaxamine (Desferal) is an iron-chelating drug,which binds excess iron so it can be excreted by the kidneys.It does not prevent blood-transfusion reactions, stimulate red-blood-cell production,or provide vitamin supplementation.
