A patient develops confusion and seizures with hyponatremia; which intervention is most important?

• A. Gradual correction of serum sodium and restriction of free water; monitor neuro status
• B. Rapid correction of serum sodium with hypertonic saline
• C. Immediate aggressive fluid restriction with no monitoring
• D. Increase free water intake to dilute sodium

Answer: (A)

The important idea is to raise the sodium level slowly to relieve brain swelling without triggering injury from too-rapid shifts. In hyponatremia with neurologic symptoms, you want to correct the dilution safely by gradually increasing serum sodium and limiting free water intake, while closely watching the patient’s neurological status to adjust the rate as needed. Rapidly bolstering sodium with aggressive treatment can cause osmotic demyelination syndrome, and completely restricting fluids without monitoring or simply increasing water intake would either worsen the problem or fail to protect the brain. So, a careful, gradual correction with fluid restriction and neuro monitoring best protects the brain while correcting the electrolyte imbalance.
