Which statement best describes the safe approach to correcting hyponatremia?

• A. Rapidly correct sodium to normal as quickly as possible.
• B. Do nothing and reassess later.
• C. Correct sodium slowly with close neuro monitoring and avoid rapid correction.
• D. Administer hypertonic saline without monitoring.

Answer: (C)

Hyponatremia correction must be gradual to protect the brain. When sodium is raised too quickly, especially after a period of chronic hyponatremia, the brain can’t adapt fast enough and demyelination can occur, leading to serious neurologic injury. That’s why the safest approach is to correct sodium slowly while closely watching the patient’s neurologic status and checking serum sodium frequently. In practice this means aiming for a modest increase in the first 24 hours and avoiding rapid overcorrection. Manage the fluid status based on the patient’s volume state, treat the underlying cause, and reserve any use of hypertonic saline for those with severe symptoms, but only with meticulous monitoring. In some cases, clinicians may use desmopressin to prevent overcorrection if the sodium is rising too quickly. This careful, gradual strategy protects the nervous system while addressing the hyponatremia.
