Which fluid is most appropriate to treat hypernatremia?

• A. D5 1/4 NS
• B. Normal saline
• C. D5W
• D. 0.9% NS

Answer: (A)

D5 1/4 NS, or 5% dextrose in 0.225% saline solution, is considered the most appropriate fluid for treating hypernatremia because it provides a controlled way to lower serum sodium levels while also delivering hydration. In cases of hypernatremia, where there is an increased concentration of sodium in the blood, the goal is to gradually reduce sodium levels to avoid complications that can arise from rapid changes in serum sodium. The presence of dextrose in D5 1/4 NS helps to provide calories and can support metabolic processes, while the diluted saline component helps to ensure that sodium levels are addressed without providing excessive sodium. The isotonic properties of the fluid allow for a safe and gradual correction of hypernatremia. Other options, such as normal saline and 0.9% NS, contain higher concentrations of sodium and are typically used in different clinical scenarios, such as hypovolemia or for volume resuscitation. D5W, while it provides hydration, does not contain any sodium and is not suitable for correcting hypernatremia on its own since it could lead to free water excess without addressing the sodium imbalance directly. Thus, D5 1/4 NS strikes the
