He reports garlic odor on his breath following acute occupational exposure to an arsenic-contaminated insecticide. Serum arsenic level is elevated at 45 mcg/dL (normal <5). Urine output remains adequate. He denies respiratory symptoms. Which chelating agent is most appropriate for this acute arsenic poisoning?

  1. A)Deferoxamine
  2. B)Succimer
  3. C)Protamine sulfate
  4. D)DimercaprolGABARITO
  5. E)Methylene blue

Explicação
