A patient with a history of bipolar I disorder is prescribed fluoxetine (Prozac) for a depressive episode. What is the nurse's priority action?

A. While gastrointestinal side effects are common with fluoxetine, they are not the priority concern in the context of bipolar disorder. B. Fluoxetine (Prozac) is an SSRI used to treat depression, but in patients with bipolar disorder, it can trigger a manic episode. Therefore, the nurse's priority is to monitor for signs of mania, such as increased energy, euphoria, or impulsivity. C. Administering the medication as ordered is essential, but the nurse must be vigilant for signs of mania, especially with SSRIs in bipolar patients. D. Educating about weight gain is important but does not address the immediate risk of precipitating mania with fluoxetine in a bipolar patient.
