A nurse is caring for a client who has hypernatremia and requires IV fluid therapy due to his NPO status. Which of the following solutions should the nurse prepare to infuse for this client?

A. This is an isotonic solution that contains sodium, which may worsen hypernatremia rather than correct it. It is not the best choice for lowering sodium levels. B. While this is a hypotonic solution once the dextrose is metabolized, it is typically used for clients requiring additional calories or for hypoglycemia management, not first-line treatment for hypernatremia. C. This is a hypertonic solution that contains a high sodium content, which can worsen hypernatremia. D. This is a hypotonic solution that helps lower serum sodium levels by diluting the sodium concentration in the blood. It is appropriate for treating hypernatremia in clients who cannot take fluids orally.
