A nurse is caring for a client who is experiencing alcohol withdrawal and notes visible tremors, elevated blood pressure, and increased heart rate. Which of the following medications should the nurse prepare to administer?

Choice A reason: Lorazepam, a benzodiazepine, is the first-line treatment for moderate to severe alcohol withdrawal. It reduces CNS hyperactivity, prevents seizures, and stabilizes vital signs. Choice B reason: Disulfiram is used for long-term abstinence by inducing aversive reactions to alcohol. It is contraindicated during acute withdrawal due to risk of worsening symptoms. Choice C reason: Naltrexone is used for relapse prevention by reducing cravings. It is not appropriate during withdrawal and may precipitate symptoms if opioids are present. Choice D reason: Haloperidol may be used for agitation or hallucinations but does not address the autonomic instability of withdrawal. It is not a primary treatment for tremors or elevated vitals.
