Which of the following is a medical treatment for lead poisoning?

Chelation is the correct medical treatment for lead poisoning as it specifically targets the lead present in the body. This process involves administering chelating agents—substances that bind to heavy metals like lead—allowing for their safe elimination from the body. Chelation therapy helps reduce blood lead levels and minimize the associated toxic effects on the brain and other organs. It is particularly effective in cases of moderate to severe lead poisoning.

In contrast, radiation therapy is primarily used for treating certain types of cancer and does not have a role in lead poisoning treatment. Antibiotics are used to combat bacterial infections, not toxic metal exposure. Physical therapy generally aids in rehabilitation after injury or surgery and does not address the underlying issue of lead toxicity. Understanding these distinctions is crucial for recognizing the appropriate interventions for lead poisoning.
