A client has overdosed on scopolamine (Scopace) while being treated for motion sickness. The nurse recognizes she will administer which reversal medication for an anticholinergic overdose?

Choice A reason: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose. It is not effective against anticholinergic overdoses, such as those caused by scopolamine. Therefore, naloxone is not the appropriate reversal agent for this situation. Choice B reason: Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepine overdose. It is not effective in reversing anticholinergic toxicity and does not have the necessary action to counteract the effects of scopolamine. Thus, flumazenil is not the correct choice for treating an anticholinergic overdose. Choice C reason: Physostigmine is an acetylcholinesterase inhibitor that can reverse the effects of anticholinergic overdose by increasing acetylcholine levels in the brain. It is the recommended antidote for anticholinergic toxicity, including overdoses caused by scopolamine. Administering physostigmine can help alleviate the symptoms of anticholinergic overdose. Choice D reason: Sertraline is a selective serotonin reuptake inhibitor (SSRI) used to treat depression and anxiety. It has no role in reversing anticholinergic overdoses and does not counteract the effects of scopolamine. Therefore, sertraline is not appropriate for this situation.
