A nurse is caring for an infant who has inadequate motility of part of the intestine resulting in a mechanical obstruction. The nurse should identify this finding as a manifestation of which of the following disorders?

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.

Options A (increased ability of tissue to retain fluid) and B (reduced blood pressure) are not typical signs of improvement in Nephrotic Syndrome. The primary focus is on reducing protein loss and alleviating edema.

Option C. Increased diuresis and decreased protein loss in urine.

Nephrotic Syndrome is characterized by increased urinary protein loss, resulting in hypoalbuminemia, edema, and other symptoms. Improvement in Nephrotic Syndrome is typically indicated by:

Increased diuresis: An increase in urine output suggests that the child is excreting excess fluid, which can help reduce edema (swelling).

Decreased protein loss in urine: A reduction in proteinuria (loss of protein in the urine) is a positive sign, as it indicates that the damaged kidney glomeruli are functioning more effectively in retaining protein.

Option D (decreased protein levels in serum) is also not a clear sign of improvement. While it may be related to reduced protein loss in urine, it does not directly reflect the overall improvement of the condition. Monitoring protein levels in the urine (proteinuria) is a more specific indicator of Nephrotic Syndrome management.
