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?

Choice A reason: Disulfiram is an oral medication, not injectable, used to deter alcohol consumption by causing adverse reactions. Monthly injections apply to drugs like naltrexone, not disulfiram, which requires daily oral dosing to maintain its deterrent effect in alcohol use disorder treatment.
Choice B reason: Taking disulfiram before quitting alcohol is incorrect, as it is started post-abstinence to prevent relapse. Disulfiram inhibits aldehyde dehydrogenase, causing acetaldehyde buildup if alcohol is consumed, making it effective only in alcohol-free clients to deter drinking.
Choice C reason: Avoiding over-the-counter medications with alcohol is correct, as disulfiram causes severe reactions (nausea, flushing) with alcohol ingestion, including from medications like cough syrups. This reflects understanding of disulfiram’s mechanism, ensuring safety by preventing unintended alcohol exposure.
Choice D reason: Continuing disulfiram for 5 years is not standard, as duration varies per treatment plan. Disulfiram supports early abstinence, not fixed long-term use. This statement misrepresents its role, as therapy length depends on individual recovery needs, not a predetermined timeframe.

Choice A reason: Avoiding physical exercise is not recommended for multiple sclerosis, as moderate activity like walking or stretching improves muscle strength, balance, and fatigue management. Complete avoidance leads to deconditioning, worsening mobility and fatigue, which are common in MS, making this instruction counterproductive to symptom management.
Choice B reason: Taking hot baths is not advised for multiple sclerosis, as heat can exacerbate symptoms like fatigue and muscle weakness due to temperature sensitivity (Uhthoff’s phenomenon). Cool or lukewarm baths are safer, supporting symptom control, making this instruction harmful and inappropriate for MS management.
Choice C reason: Performing daily stretching exercises improves flexibility, reduces spasticity, and enhances mobility in multiple sclerosis. Stretching strengthens muscles and prevents contractures, supporting functional independence. This aligns with evidence-based MS management to mitigate symptoms and improve quality of life, making it the correct instruction.
Choice D reason: Limiting fluid intake to reduce bladder irritation is inappropriate, as adequate hydration (2-3 L/day) prevents urinary tract infections, common in MS due to bladder dysfunction. Fluid restriction can worsen symptoms and dehydration, making this instruction incorrect for managing MS-related bladder issues effectively.
