A client with bipolar disorder is prescribed lithium. Which statement indicates a need for further teaching?

Choice A rationale Lithium has a narrow therapeutic index, meaning the difference between a therapeutic dose and a toxic dose is small. Regular blood tests are crucial to monitor serum lithium levels, typically ranging from 0.6 to 1.2 mEq/L, to ensure the dose is therapeutic and to prevent toxicity. This statement indicates a correct understanding of lithium therapy and does not require further teaching. Choice B rationale Tremors, nausea, and diarrhea are common early signs of lithium toxicity. The patient should be taught to recognize and report these symptoms to their healthcare provider. This statement demonstrates the patient's awareness of potential adverse effects and the importance of prompt reporting, which is a correct understanding of the medication. The nurse should reinforce this patient teaching. Choice C rationale Stopping lithium abruptly can lead to a relapse into a manic or depressive episode. Lithium is a mood stabilizer, and its effectiveness is dependent on consistent, long-term use. This statement indicates a significant misunderstanding of the medication's purpose and the chronicity of bipolar disorder, necessitating immediate and comprehensive further teaching. The patient's illness requires ongoing treatment. Choice D rationale This statement shows an understanding of the chronic nature of bipolar disorder and the need for long-term medication adherence to maintain mood stability. Continuing the medication even when feeling better is essential to prevent mood swings and relapse. This statement reflects a correct understanding of the treatment plan, and no further teaching is required.
