A client diagnosed with bipolar disorder has rapidly changing mood cycles. The health care provider prescribes an anticonvulsant medication. To prepare teaching materials, which drug should the nurse anticipate will be prescribed?

Choice A reason: Carbamazepine is an anticonvulsant commonly used as a mood stabilizer in bipolar disorder, especially in cases of rapid cycling. It helps reduce manic episodes and stabilize mood fluctuations. Choice B reason: Clonidine is primarily used for hypertension and ADHD. It is not classified as an anticonvulsant or mood stabilizer for bipolar disorder. Choice C reason: Risperidone is an atypical antipsychotic, not an anticonvulsant. While it may be used adjunctively in bipolar disorder, it is not the primary choice for rapid cycling. Choice D reason: Clonazepam is a benzodiazepine used for anxiety and seizures. It is not a first-line mood stabilizer and carries a risk of dependence.
