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. Clonidine: While clonidine can alleviate some nicotine withdrawal symptoms such as anxiety and irritability, it is not a first-line therapy for smoking cessation and is usually reserved for clients who cannot use other approved medications. B. Naltrexone: Naltrexone is primarily prescribed for alcohol and opioid use disorders and has no significant effect on nicotine addiction or withdrawal. C. Bupropion: Bupropion is an effective smoking cessation aid that reduces nicotine cravings and withdrawal by affecting neurotransmitters in the brain. It is FDA-approved specifically for helping clients quit smoking. D. Chlordiazepoxide: This benzodiazepine is used to manage anxiety and alcohol withdrawal but does not target nicotine dependence or support smoking cessation efforts.
