A nurse is caring for a client who has bulimia nervosa has a new prescription for a selective serotonin reuptake inhibitor (SSRI). Which of the following medications should the nurse anticipate administering?

A. Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that is FDA-approved for the treatment of bulimia nervosa. It helps reduce binge-eating and purging behaviors by increasing serotonin activity in the brain, which can improve mood and impulse control. Fluoxetine is often prescribed in higher doses for bulimia than for depression. B. Naltrexone is an opioid antagonist used primarily for alcohol or opioid use disorders. While it can sometimes be used off-label to reduce cravings or binge-eating in certain disorders, it is not the first-line SSRI treatment for bulimia nervosa. C. Valproate is a mood stabilizer used for bipolar disorder or seizure disorders. It is not indicated for the treatment of bulimia nervosa. D. Olanzapine is an atypical antipsychotic used for schizophrenia or bipolar disorder. Although it may have off-label use for anorexia nervosa to promote weight gain, it is not a first-line treatment for bulimia nervosa and is not an SSRI.
