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

Rationale: A. "I will plan to continue taking this medication for at least 5 years.": Disulfiram therapy is not prescribed for a fixed duration such as 5 years. The length of treatment depends on the client’s motivation and response, typically continuing until long-term abstinence is maintained. B. "My provider wants me to take this medication for 2 weeks before I try to quit drinking.": Disulfiram must be started only after the client has abstained from alcohol for at least 12 hours, not before quitting. Taking it while alcohol is still in the system can trigger severe reactions such as flushing, nausea, vomiting, and hypotension. C. "I should avoid over-the-counter medications that contain alcohol.": Even small amounts of alcohol—such as in cough syrups, mouthwash, or sauces—can cause a dangerous disulfiram-alcohol reaction. Clients must avoid all alcohol-containing products. D. "I will need to get a monthly injection of this medication.": Disulfiram is taken orally, usually once daily, and does not come in injectable form. The injectable medication used for alcohol dependence is naltrexone (Vivitrol).
