A nurse is contributing to the plan of care for a client who has hypernatremia. Which of the following interventions should the nurse recommend to include in the plan?

A. Administer a laxative: A laxative can increase fluid loss through the intestines, worsening dehydration and concentrating serum sodium levels even further. Hypernatremia often results from fluid deficit, so additional fluid loss would aggravate the imbalance. B. Restrict sodium intake: Limiting dietary sodium helps reduce further increases in serum sodium levels and supports correction of the imbalance. This intervention works alongside fluid replacement to gradually normalize sodium concentration. It also prevents exacerbation of neurologic symptoms associated with hypernatremia. C. Restrict fluid intake: Reducing fluid intake would cause serum sodium levels to rise further by increasing concentration. Hypernatremia typically requires careful fluid replacement to restore balance, not restriction. Limiting fluids would worsen dehydration and delay recovery. D. Administer a potassium supplement: Potassium levels are not directly addressed when managing hypernatremia unless there is a documented deficit. Supplementing potassium without evidence of hypokalemia adds unnecessary risk and does not contribute to correcting high sodium levels.
