Which question is a priority for the nurse to ask a client before administering disulfiram?

The priority question for the nurse to ask before administering disulfiram is focused on the client's last consumption of alcohol. Disulfiram acts as an alcohol deterrent by inhibiting the enzyme acetaldehyde dehydrogenase, leading to unpleasant and potentially severe reactions if alcohol is consumed. These reactions can include flushing, nausea, vomiting, and palpitations. Therefore, it is critical to establish how long it has been since the client last ingested alcohol to ensure their safety and the efficacy of the treatment.

Asking about recent alcohol consumption directly addresses the risk of these adverse effects and is essential for proper patient management. It is generally advised that patients abstain from alcohol for at least 12 hours before starting disulfiram, and assessing the timing of their last alcoholic beverage is vital. This strategy supports safe practice and optimizes the therapeutic outcomes of disulfiram therapy.

While inquiries about cough, allergies, and herbal supplement use are important, they do not pose the immediate risk associated with disulfiram treatment compared to the dangers of alcohol interaction. Therefore, prioritizing the question about the last drink of alcohol ensures immediate safety considerations are met.
