Correct Answer is B

Explanation

A. Increasing sodium intake would exacerbate hypernatremia, not correct it. Hypernatremia is characterized by an excess of sodium in the blood, so the goal of treatment is to lower sodium levels, not increase them.
B. Infusing hypotonic IV fluids, such as 0.45% NaCl or D5W (5% dextrose in water), helps to dilute the high sodium concentration in the blood and can assist in correcting hypernatremia. Hypotonic fluids move water into cells and help balance the sodium levels by promoting hydration and lowering the sodium concentration.
C. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia (elevated potassium levels), not hypernatremia. It works by exchanging potassium for sodium in the gastrointestinal tract and would not address hypernatremia.
D. Implementing a fluid restriction is generally not the best approach for treating hypernatremia. In fact, fluid restriction could worsen hypernatremia by limiting the client's fluid intake and not addressing the sodium imbalance. The primary goal in hypernatremia is usually to rehydrate the patient with appropriate fluids.
