NCLEX RN Practice Question

The correct answer is to provide fluids because a serum sodium level of 154 mEq/L indicates hypernatremia, which typically results from dehydration or loss of water. Administering fluids, either orally or intravenously, helps lower the sodium level by diluting it and restoring fluid balance. Monitoring intake of sodium-rich foods is useful for preventing long-term complications but does not address acute hypernatremia. Sodium bicarbonate is not indicated, as this intervention is typically for metabolic acidosis. Restricting water intake would worsen hypernatremia and is contraindicated in this situation.
