Which statement describes the appropriate initial management for hyponatremia?

• A. Increase dietary sodium immediately
• B. Administer rapid IV fluids to raise Na+ quickly
• C. Implement safety precautions and address underlying cause; monitor Na+ closely
• D. Ignore neurological symptoms if mild

Answer: (C)

Initial management of hyponatremia hinges on safety, identifying and addressing the underlying cause, and watching the sodium level closely rather than rushing to fix the numbers. Protect the patient from injury and monitor neurological status because even mild symptoms can progress. At the same time, determine the fluid status and the root reason for the low sodium—such as SIADH, hypovolemia, heart or kidney failure, or medication effects—and tailor the plan to that cause (for example, fluid restriction for SIADH, isotonic fluids if hypovolemic, and stopping offending drugs). The sodium should be monitored with serial labs to guide subsequent treatment and to avoid overcorrection, which can cause osmotic demyelination. In cases with severe neurologic symptoms, more aggressive therapy may be needed, but the foundational step remains safety, cause identification, and close monitoring.
