The nurse observes that a client with sickle cell anemia and on a blood transfusion regimen has cardiac dysrhythmias due to iron overdose toxicity. Which medication is most beneficial to this client?
Trientine
Dimercaprol
Ferrous gluconate
Defaroxamine
The Correct Answer is D
A. Trientine: Trientine is a medication used to treat copper overload in conditions like Wilson's disease. It is not indicated for iron overdose or toxicity.
B. Dimercaprol: Dimercaprol, also known as BAL (British Anti-Lewisite), is a chelating agent used to treat heavy metal poisoning but is not primarily used for iron overload or toxicity.
C. Ferrous gluconate: Ferrous gluconate is an iron supplement used to treat iron-deficiency anemia by providing additional iron to the body. It is not appropriate for treating iron overdose, as it would worsen the situation.
D. Deferoxamine.
Iron overdose, also known as iron toxicity, can lead to serious complications, including cardiac dysrhythmias. Deferoxamine is a chelating agent used to remove excess iron from the body in cases of iron overload or toxicity, such as in patients with conditions like sickle cell anemia who require frequent blood transfusions. It binds to excess iron and helps excrete it from the body, reducing the risk of iron-related complications, including cardiac issues.
