A client will be taking disulfiram (Antabuse) after discharge from an alcohol treatment program. Which patient statement would indicate that teaching has been effective?

A. "Disulfiram is safe to take with any over-the-counter cold medication.": Many OTC cold and cough products contain hidden alcohol, which can trigger a dangerous disulfiram-alcohol reaction. Patients must be taught to check labels and avoid alcohol-containing products. B. "Drinking alcohol while taking disulfiram can cause a severe reaction.": Disulfiram inhibits the enzyme aldehyde dehydrogenase, causing accumulation of acetaldehyde when alcohol is ingested, leading to flushing, nausea, vomiting, palpitations, and potentially life-threatening complications. C. "If I drink while taking disulfiram, it will make me vomit before the alcohol affects me.": The reaction involves more than simple vomiting. Severe hypotension, respiratory distress, and even cardiovascular collapse can occur, so this minimizes the seriousness of the effects. D. "Disulfiram will block my cravings for alcohol, so I'll have less desire to drink.": Disulfiram does not reduce cravings or desire for alcohol. Its purpose is deterrence through fear of a severe reaction, not craving suppression, which is more characteristic of naltrexone.
