Answer to Question 1

ANS: C
Initial treatment for poisoning involves supportive care. IV infusions of normal saline or Ringer's solution should be given to restore volume lost by vomiting. Antiemetics are not indicated. Activated charcoal is given when the ingested substance is known and only if it will help neutralize the substance. Toxicology testing is important, but supportive care is provided initially.

Answer to Question 2

ANS: A
Edetate calcium disodium (calcium EDTA) is administered to children as a chelating agent for lead poisoning. Its principle toxicity is renal tubular necrosis, as evidenced by hematuria and proteinuria. Daily urinalysis should be performed. The medication is given IV or IM, not orally. The drug does not have significant effects on the heart rate or blood pressure. It does not cause hepatotoxicity.
