A nurse is reviewing a client’s laboratory results. Which of the following findings should the nurse be concerned about?

A. Sodium 126 mEq/L: This value indicates hyponatremia, which can cause confusion, seizures, and fluid imbalance. Normal sodium levels are 135-145 mEq/L, so this is a critical finding. B. Chloride 99 mmol/L: This is within the normal range (96-106 mmol/L), so it is not concerning. C. Albumin 4.9 mg/dL: Normal albumin levels are 3.5-5.0 mg/dL, so this value is within range. D. Potassium 3.6 mEq/L: Normal potassium levels are 3.5-5.0 mEq/L. This value is on the lower end but still within normal limits.
