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?

Disulfiram (Antabuse) blocks aldehyde dehydrogenase, causing a severe reaction (flushing, nausea, vomiting, palpitations) when any alcohol is consumed — including hidden sources such as mouthwash, cough syrups, aftershave, and vinegar-based foods. Avoiding all alcohol-containing products is essential. The alcohol sensitivity persists for up to 2 weeks after stopping disulfiram (not 24 hours). Disulfiram is used alongside (not instead of) support programs like AA. It is prescribed for clients committed to sobriety, not just those at high relapse risk.
