Default c) Edetate calcium disodium

I am not sure but it looks like its lead poisoning.
so treatment would be CaEDTA or c) Edetate calcium disodium

Default correct answer

The answer is b) Dimercaprol

This patientís clinical manifestations are consistent with the diagnosis of chronic mercury poisoning. Treatment consists of eliminating the exposure and chelation with dimercaprol for severe poisoning with inorganic mercurial salts.
