Write answer in between .Q:A 5-year-old boy is brought to the emergency room lapsing in and out of consciousness. The mother reports that 30 minutes ago, the young boy was found exiting the garage severely confused. A container of freshly spilled antifreeze was found on the garage floor. The next appropriate step would be to administer:? A: Dimercaprol, B: N-acetylcysteine, C: Ammonium chloride, D: Flumazenil, E: Fomepizole,  <response>: This is a case of suspected antifreeze ethylene glycol poisoning in a child based on the history of being found confused after exposure to spilled antifreeze. The next step would be to administer an antidote to prevent further metabolism of ethylene glycol into its toxic metabolites. The correct antidote options here are fomepizole or ethanol, which competitively inhibit alcohol dehydrogenase to block formation of the toxic metabolites. Dimercaprol BAL can also bind and enhance excretion of ethylene glycols metabolites, but is not preferred as initial therapy. N-acetylcysteine is used for acetaminophen poisoning, ammonium chloride for metabolic alkalosis, and flumazenil for benzodiazepine overdose - none of which apply here.E: Fomepizole
