A client with a diagnosis of Bipolar Disorder has been taking lithium carbonate; however, they stopped it 2 months ago because they “didn’t need it anymore.” The client is now talking in a loud voice, pacing, and flailing their arms in exaggerated gestures. The physician orders a “now dose” of lithium and olanzapine, a second-generation antipsychotic agent. The client’s family asks why olanzapine is ordered. What is the nurse’s most appropriate response?

Choice A Reason: Prevents Extrapyramidal Side EffectsExtrapyramidal side effects (EPS) are drug-induced movement disorders that include symptoms such as tremors, rigidity, bradykinesia, and tardive dyskinesia. These side effects are commonly associated with first-generation antipsychotics. While second-generation antipsychotics like olanzapine have a lower risk of causing EPS, their primary use in this context is not to prevent these side effects. Therefore, this choice is not the most appropriate response to the family’s question.Choice B Reason: Reduces Agitation Until the Lithium Takes EffectOlanzapine is a second-generation antipsychotic that is effective in managing acute agitation and psychotic symptoms in patients with bipolar disorder. Lithium, while effective for long-term mood stabilization, takes several days to weeks to reach therapeutic levels and exert its full effect. During this period, olanzapine can help reduce the client’s agitation and stabilize their mood. This makes it the most appropriate response to the family’s question.Choice C Reason: Cures Manic SymptomsWhile olanzapine can help manage manic symptoms, it does not “cure” them. Bipolar disorder is a chronic condition that requires ongoing management with medications and therapy. The term “cure” is misleading as it implies a permanent resolution of symptoms, which is not the case with bipolar disorder. Therefore, this choice is not accurate.Choice D Reason: Ensures High-Quality SleepOlanzapine can have sedative effects and may help improve sleep in some patients. However, its primary use in this scenario is to manage acute agitation and psychotic symptoms rather than to ensure high-quality sleep. While improved sleep may be a beneficial side effect, it is not the main reason for its prescription in this context.
