A client with bipolar disorder admitted with severe depression and suicidal ideation receives a prescription for lithium carbonate, which instruction should the nurse provide to the client?

Lithium carbonate is a mood stabilizer commonly used to treat bipolar disorder. However, it has a narrow therapeutic index and requires careful monitoring of serum levels to avoid toxicity. One of the major concerns with lithium therapy is the potential for drug interactions and toxicity. NSAIDs such as ibuprofen and naproxen can increase lithium levels by reducing its excretion and can lead to lithium toxicity. Therefore, it is essential to instruct the client to eliminate the use of NSAIDs while taking lithium. Option b) Avoid consuming all foods that contain iodine is incorrect because iodine is not contraindicated with lithium. However, excessive iodine intake can interfere with thyroid function, which can exacerbate mood instability. Option c) Notify healthcare provider prior to dental procedures is not specific to lithium therapy and is a general precaution that patients with bipolar disorder should follow before any medical or dental procedures. Option d) Monitor blood glucose levels daily is also not directly related to lithium therapy. While lithium can cause diabetes insipidus, which can lead to excessive thirst and urination, it does not typically affect blood glucose levels.
