Verified step by step guidance1
Understand the concept of hyponatremia: Hyponatremia is a condition characterized by low sodium levels in the blood. It is important to know the normal range of serum sodium concentration to identify hyponatremia.
Identify the normal range of serum sodium concentration: The typical normal range for serum sodium is approximately 135 to 145 mEq/L.
Compare each given sodium concentration with the normal range: Evaluate each option to determine if it falls below the normal range.
Analyze the options: 145 mEq/L and 150 mEq/L are within or above the normal range, so they do not indicate hyponatremia. 135 mEq/L is at the lower limit of normal, so it is not considered hyponatremia.
Identify the concentration indicating hyponatremia: 130 mEq/L is below the normal range, indicating hyponatremia.
