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

Answer and Explanation

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.

Correct Answer is A

Explanation

A.Growth of that leg may be affected.

When a fracture occurs near the epiphyseal plate of a long bone, such as the femur, there is a risk of damage to the growth plate. The growth plate (epiphyseal plate) is responsible for longitudinal bone growth in children. If the growth plate is injured or damaged during the fracture, it can potentially lead to growth disturbances and affect the growth of that leg.

B. Risk for infection at this location is increased: While any fracture has a risk of infection, the proximity to the epiphyseal plate doesn't necessarily increase the risk of infection.

C. Long bones contain marrow, which increases the risk for anemia: The presence of bone marrow in long bones is unrelated to the potential effects on bone growth after a fracture near the epiphyseal plate.

D. Fracture repair will necessitate prolonged traction: The use of traction for fracture repair can vary depending on the type and location of the fracture. However, the primary concern with a fracture near the epiphyseal plate is its potential impact on bone growth.

A. Increased pulse rate B. Increased blood pressure C. Warm Skin D. Cyanosis of the nail beds

Correct Answer is A

Explanation

A. Increased pulse rate.

Iron deficiency anemia can lead to a reduced oxygen-carrying capacity in the blood. As a compensatory mechanism, the heart may pump faster to deliver more oxygen to tissues. This can result in an increased pulse rate. Children with iron deficiency anemia may also experience weakness, fatigue, and pallor.

B. Increased blood pressure is not a common symptom of iron deficiency anemia. In fact, iron deficiency anemia can often lead to lower blood pressure due to the reduced oxygen-carrying capacity of the blood.

C. Warm skin is not a typical symptom of iron deficiency anemia. Skin temperature may not be directly affected by this condition.

D. Cyanosis of the nail beds is not a symptom of iron deficiency anemia. Cyanosis refers to bluish discoloration of the skin or mucous membranes due to reduced oxygen levels in the blood, which is more commonly associated with respiratory or cardiovascular issues. Iron deficiency anemia primarily affects the oxygen-carrying capacity of the blood but does not lead to cyanosis.
