A nurse is caring for a client who is receiving treatment for chronic alcohol use disorder. Which of the following medications should the nurse plan to administer to assist the client in maintaining abstinence by aversion therapy?

The correct answer is D: Disulfiram. Disulfiram is used in aversion therapy to deter alcohol consumption by causing unpleasant effects when alcohol is consumed. It inhibits the enzyme aldehyde dehydrogenase, leading to accumulation of acetaldehyde, causing symptoms such as flushing, nausea, and palpitations. Lorazepam (A) is a benzodiazepine used for anxiety, not alcohol aversion. Atenolol (B) is a beta-blocker used for hypertension, not aversion therapy. Carbamazepine (C) is an anticonvulsant used for seizures, not alcohol aversion.
