A client asks the nurse, "What will happen if I drink while taking disulfiram?" What is the best response by the nurse?

Choice A reason: This is incorrect because disulfiram does not reduce cravings for alcohol. Its mechanism of action is based on creating an aversive reaction when alcohol is consumed, not on suppressing the desire to drink. Medications such as naltrexone or acamprosate are used to reduce cravings, but disulfiram works differently. Choice B reason: This is inaccurate because alcohol will still exert its effects when consumed. Disulfiram does not block alcohol’s pharmacological action; instead, it interferes with alcohol metabolism, leading to accumulation of acetaldehyde, which causes unpleasant symptoms. Choice C reason: This is incorrect because disulfiram does not reverse alcohol’s effects. It does not act as an antidote. Instead, it causes a toxic reaction when alcohol is ingested, making drinking highly unpleasant and dangerous. Choice D reason: This is correct because disulfiram inhibits aldehyde dehydrogenase, leading to accumulation of acetaldehyde when alcohol is consumed. This results in severe reactions such as throbbing headache, nausea, vomiting, flushing, hypotension, and palpitations. The reaction can be dangerous and is intended to deter alcohol consumption.
