A nurse is reinforcing teaching for a client who has been treated for alcohol use disorder and is being discharged. Which of the following medications should the nurse anticipate the provider to prescribe for relapse prevention?

Rationale: A. Librium: Librium (chlordiazepoxide) is a benzodiazepine used primarily during alcohol withdrawal to manage symptoms such as anxiety, tremors, or seizures. It is not used for long-term relapse prevention due to the risk of dependence and lack of deterrent effect on alcohol use. B. Clonidine: Clonidine is an antihypertensive agent that can help reduce autonomic symptoms during acute alcohol or opioid withdrawal. However, it does not play a role in preventing relapse or deterring future alcohol use. C. Disulfiram: Disulfiram works by producing unpleasant effects like nausea and vomiting when alcohol is consumed, thereby discouraging the client from drinking. It is specifically used for relapse prevention in clients who are motivated to remain abstinent and understand the consequences of drinking while on the medication. D. Phenobarbital: Phenobarbital, a barbiturate, may be used in certain alcohol withdrawal protocols for seizure control or severe withdrawal symptoms. However, it is not used for relapse prevention and carries a high potential for dependence and sedation.
