A nurse is caring for a client who has an opioid use disorder.The nurse should anticipate that the provider will prescribe which of the following medications for treatment?

Choice A rationaleDiazepam is a benzodiazepine, typically used for anxiety, muscle spasms, and seizures. While it has a calming effect, it does not directly address opioid use disorder and carries a risk of misuse and dependence, potentially exacerbating the client's condition.Choice B rationalePhenobarbital is a long-acting barbiturate used to control seizures. It is not a primary treatment for opioid use disorder and has a high potential for dependence and serious withdrawal symptoms if discontinued abruptly.Choice C rationaleBuprenorphine is a partial opioid agonist that binds to opioid receptors in the brain, reducing cravings and withdrawal symptoms without producing the full euphoric effects of other opioids. It is a key medication in medication-assisted treatment (MAT) for opioid use disorder, helping clients manage their addiction and transition to recovery.Choice D rationaleChlordiazepoxide is another benzodiazepine, primarily used for anxiety and alcohol withdrawal. Similar to diazepam, it does not directly treat opioid use disorder and carries a risk of dependence and misuse in individuals with substance use disorders.
