A nurse is planning care for a client who is experiencing acute alcohol withdrawal. Which of the following medications should the nurse expect to administer?

A. Methadone: Methadone is an opioid agonist used for opioid dependence and pain management. It does not treat the symptoms of alcohol withdrawal and is not indicated in this scenario. B. Chlordiazepoxide: Chlordiazepoxide is a benzodiazepine commonly used to manage acute alcohol withdrawal. It reduces agitation, tremors, and the risk of seizures by enhancing GABAergic activity in the central nervous system. C. Varenicline: Varenicline is used to aid smoking cessation by acting on nicotinic receptors. It does not alleviate alcohol withdrawal symptoms and is not part of standard alcohol withdrawal management. D. Buprenorphine: Buprenorphine is a partial opioid agonist used for opioid use disorder. It is not effective in treating alcohol withdrawal and does not address the associated neurological excitability or risk of seizures.
