**Core Concept**
Iron poisoning is a medical emergency that requires prompt recognition and treatment to prevent severe complications, including multi-organ failure and death. The goal of treatment is to remove the iron from the body and support the patient's vital organs.

**Why the Correct Answer is Right**
In a child with iron poisoning, stomach lavage (gastric decontamination) is not recommended as it can cause more harm than good. Desferrioxamine is the primary treatment for iron poisoning, as it chelates (binds to) the iron and facilitates its excretion. The recommended dose of desferrioxamine for iron poisoning is 15 mg/kg/hour IV, not 100 mg. X-ray abdomen is not a treatment but a diagnostic tool that may be used to assess for gastrointestinal damage. Blood transfusion may be necessary in severe cases of iron poisoning, but it is not a primary treatment for the poisoning itself.

**Why Each Wrong Option is Incorrect**
**Option A:** Stomach lavage is not recommended for iron poisoning as it can cause aspiration and worsen the patient's condition.
**Option C:** X-ray abdomen is a diagnostic tool, not a treatment for iron poisoning.
**Option D:** Blood transfusion may be necessary in severe cases, but it is not the primary treatment for iron poisoning.

**Clinical Pearl / High-Yield Fact**
In cases of iron poisoning, it is essential to note that the symptoms may not appear immediately. The child may present with symptoms several hours after ingestion, making it crucial for healthcare providers to be aware of the potential for delayed presentation.

**Correct Answer: C. Desferrioxamine IV is the correct treatment for iron poisoning, but the dose specified is incorrect. However, since option C is not available, I assume the closest correct answer is D (Blood transfusion), but the correct dose of desferrioxamine is not mentioned. Therefore, the correct answer should be B. Desferrioxamine IV (assuming the correct dose is not specified).**
