Verified step by step guidance

Step 1: Understand the condition - Iron toxicity occurs when there is an excessive amount of iron in the body, which can lead to damage in organs such as the liver, heart, and pancreas. It is important to identify the appropriate treatment to bind and remove excess iron.

Step 2: Review the options provided - The question lists Naloxone, Vitamin K, Protamine sulfate, and Deferoxamine as potential agents. Each of these has specific uses in medical treatment, so understanding their mechanisms is key.

Step 3: Analyze the mechanism of each agent - Naloxone is used to reverse opioid overdoses, Vitamin K is used to treat bleeding disorders caused by vitamin K deficiency, and Protamine sulfate is used to counteract the effects of heparin. Deferoxamine, on the other hand, is a chelating agent specifically designed to bind excess iron in the body and facilitate its excretion.

Step 4: Match the correct agent to the condition - Since iron toxicity involves excess iron, the appropriate treatment would be a chelating agent like Deferoxamine, which binds iron and helps remove it from the body.

Step 5: Conclude the reasoning - Based on the mechanisms of action, the nurse would expect Deferoxamine to be administered to treat iron toxicity, as it directly addresses the condition by removing excess iron.
