What should a nurse ensure about a client receiving lithium carbonate, considering sodium intake?

• A. They should decrease fluid intake to avoid toxicity.
• B. They should maintain a low sodium diet to help with mood.
• C. They should maintain a normal sodium intake to prevent toxicity.
• D. They should avoid high sodium foods entirely.

Answer: (C)

Maintaining a normal sodium intake for a client receiving lithium carbonate is crucial because lithium levels in the body are closely tied to sodium levels. Lithium functions similarly to sodium in the body, particularly in terms of renal handling and excretion. If sodium intake is low, the body may retain lithium, potentially leading to toxicity. Conversely, high sodium intake can lead to increased renal excretion of lithium, making it less effective. Therefore, a consistent and normal sodium intake helps to stabilize lithium levels within the therapeutic range while minimizing the risk of toxicity. This balance is essential for the effective management of conditions such as bipolar disorder, for which lithium is frequently prescribed.
