2 Which is the recommended treatment for moderate to severe lead poisoning?

Incorrect: IV fluids are typically not used in the treatment of lead poisoning. IV fluids area

conservative treatment regimen and are not indicated for treatment of lead poisoning; a more

radical therapy is needed to remove the lead from the body.

Incorrect: Treatment with antiemetic is not effective in the treatment of lead toxicity because the

heavy metal is absorbed into the body. Lead ingestion usually occurs more than one time.

Correct: The heavy metal antagonist, edetate calcium disodium, is frequently the drug of

choice for the removal of the lead toxin from the body. Chelating agents inactivate the

toxicity of the lead and cause excretion through the urine. Others drugs may treat the

symptoms of toxicity rather than remove the lead from the body. Untreated lead toxicity

can lead to a wide array of neurobehavioral problems include: attention deficithyperactivity disorder, reduced cognitive performance, irritability or lethargy,

aggressiveness, and hearing impairment. The most serious and irreversible side effect of

lead poisoning is encephalopathy, which is associated with lead levels > 100 mg/ dL.
