Which teaching point is appropriate for someone on lithium?

• A. Drink 1-2 L of fluid daily
• B. Limit fluids to 500 mL daily
• C. Avoid all sodium
• D. Avoid all water intake

Answer: (A)

Lithium therapy requires keeping the kidneys well hydrated and maintaining a normal sodium balance. Lithium is handled by the kidneys in a way similar to sodium, so dehydration or low sodium can cause the kidneys to reabsorb more lithium, increasing its level in the blood and raising the risk of toxicity. Because of this, the best teaching point is to maintain adequate fluid intake, about 1–2 liters per day, to stay hydrated and support stable lithium levels. It’s important not to restrict fluids or avoid water, and to keep sodium intake relatively consistent rather than dramatically high or low. If toxicity signs appear (t neuro symptoms like tremors, confusion, or GI upset), contact a clinician.
