What electrolyte's normal range is 135-145 mEq/L?

The normal range for sodium is indeed 135-145 mEq/L. Sodium plays a crucial role in maintaining fluid balance, transmitting nerve impulses, and muscle function. It is one of the primary electrolytes in the extracellular fluid and is important for regulating blood pressure, blood volume, and pH levels. Imbalances in sodium levels, whether too high or too low, can lead to significant clinical issues, such as dehydration, edema, or neurological symptoms.

Magnesium, calcium, and chloride have different normal ranges. Magnesium typically ranges from 1.5 to 2.5 mEq/L, calcium usually falls between 8.5 to 10.5 mg/dL, and chloride has a normal range of about 98-106 mEq/L. Understanding the specific ranges for these electrolytes is essential for proper assessment and management of patients, especially in various clinical scenarios.
