What is the normal sodium range?

Explanation:
Normal serum sodium is the balance point that maintains extracellular osmolality and supports proper nerve and muscle function. The standard reference range used in most clinical settings is 135 to 145 mEq/L. Values within this window indicate a normal sodium status; going below suggests hyponatremia, while going above suggests hypernatremia, each with its own clinical implications. Among the options, the range 135-145 mEq/L matches this established reference. The other ranges shift either the lower or upper limit outside the usual norm, so they don’t align with the typical reference interval.
