A nurse is caring for a client who begins showing signs of alcohol withdrawal delirium. Which of the following medications should the nurse administer?

The correct answer is D: Lorazepam. Lorazepam is a benzodiazepine used to manage alcohol withdrawal symptoms, including delirium. It acts by calming the central nervous system and reducing agitation and anxiety. Methadone (A) is used for opioid withdrawal, not alcohol withdrawal delirium. Acamprosate (B) is used to maintain abstinence in alcohol-dependent patients, but not for acute withdrawal symptoms. Disulfiram (C) is an aversion therapy drug used to deter alcohol consumption by causing unpleasant reactions. Therefore, it is not appropriate for managing alcohol withdrawal symptoms.
