What is the normal range for sodium (Na+) levels in a Basic Metabolic Panel?

The normal range for sodium (Na+) levels in a Basic Metabolic Panel is 135-145 mEq/L. This range is important because sodium plays a critical role in maintaining fluid balance, nerve function, and muscle contraction. Levels below or above this range can indicate various medical conditions, such as hyponatremia (low sodium) or hypernatremia (high sodium), both of which require careful assessment and management in a clinical setting. Having a clear understanding of these normal values is essential for flight paramedics, who need to make quick and informed decisions based on laboratory data. The values listed in the other choices fall outside this normal range, underscoring the importance of recognizing the established limits for proper patient evaluation and treatment.
