Answer

Closely monitor cardiovascular and mental status in patients with lead poisoning. Maintain an adequate urine output. Assess renal and hepatic functions.

Diphenhydramine may help alleviate the adverse effects of dimercaprol. Iron supplementation should be avoided in patients receiving dimercaprol chelation therapy because dimercaprol forms a complex with iron, leading to toxicity.
