A nurse in a community clinic is caring for a client who requests assistance with smoking cessation. The nurse should expect a prescription for which of the following medications?

A. Naltrexone. This medication is used for opioid and alcohol use disorders. It helps reduce cravings and the pleasurable effects of those substances but is not indicated for smoking cessation. B. Chlordiazepoxide. This is a benzodiazepine used to manage alcohol withdrawal symptoms, such as anxiety, tremors, and agitation. It is not appropriate for treating nicotine dependence. C. Clonidine. Although primarily used for hypertension, clonidine has been used off-label to manage symptoms of opioid or nicotine withdrawal. However, it is not the first-line agent for smoking cessation. D. Bupropion. This is an antidepressant also approved for smoking cessation. It helps reduce nicotine cravings and withdrawal symptoms and is often prescribed under the brand name Zyban for this purpose.
