A nurse is reviewing newly written prescriptions for a client admitted with acute mania due to bipolar I disorder. Which of the following medications should the nurse identify as appropriate for stabilizing the client’s mood during the manic phase?

Choice A reason: Valproic acid is a mood stabilizer and anticonvulsant that is highly effective in controlling acute manic episodes in bipolar I disorder. It works by increasing gamma-aminobutyric acid (GABA) activity, which stabilizes neuronal firing and reduces manic symptoms such as hyperactivity, pressured speech, and impulsivity. It is considered a first-line agent for acute mania. Choice B reason: Bupropion is an antidepressant that primarily affects norepinephrine and dopamine. It is not appropriate for acute mania because antidepressants can exacerbate manic symptoms and destabilize mood in bipolar disorder. Its use is more appropriate in depressive episodes, not manic phases. Choice C reason: Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) antidepressant. Like bupropion, it can worsen mania if given during the manic phase. Antidepressants are generally avoided in acute mania unless combined with a mood stabilizer, and even then, they are used cautiously. Choice D reason: Alprazolam is a benzodiazepine used for anxiety disorders. While it may provide short-term sedation, it does not stabilize mood or treat the underlying pathophysiology of mania. It is not considered an appropriate treatment for bipolar mania.
