A nurse is reviewing a client's admission laboratory findings that indicate the client has hyponatremia. Which of the following laboratory findings should the nurse also expect to be below the expected reference range?

Rationale: A. Chloride levels often decrease along with sodium, as they are closely related electrolytes. Hyponatremia is commonly accompanied by hypochloremia. B. Calcium levels are regulated independently of sodium and are not typically affected by hyponatremia. C. Potassium may be normal, low, or even high depending on the underlying cause; it is not consistently low with hyponatremia. D. Magnesium levels do not typically mirror sodium levels and are regulated separately.
