A nurse is teaching a client who has alcohol use disorder about disulfiram. Which of the following client statements indicates an understanding of the teaching?

Rationale: A. "Taking disulfiram is an alternate therapy instead of joining Alcoholics Anonymous.": Disulfiram is a pharmacologic aid and should be used in combination with counseling or support groups like Alcoholics Anonymous. It is not a standalone treatment and does not replace behavioral therapies. B. "I should avoid products containing alcohol, like mouthwash, while taking this medication.": Disulfiram causes a severe reaction when alcohol is ingested, even in small amounts found in products like mouthwash or cough syrup. Avoiding all alcohol-containing products demonstrates correct understanding of safety precautions while taking this medication. C. "Disulfiram is mainly used for people who are at a high risk for a relapse of drinking alcohol.": Disulfiram is primarily used to maintain abstinence by causing unpleasant reactions with alcohol, but it is not limited to clients at high risk of relapse. It is important for all clients on disulfiram to understand adherence and alcohol avoidance. D. "My sensitivity to alcohol will go away 24 hours after I stop taking this medication.": Disulfiram’s effects persist for up to 14 days after discontinuation, not just 24 hours. The client must continue to avoid alcohol for a longer period even after stopping the medication to prevent adverse reactions.
