The nurse is caring for a patient who has been vomiting.The patient's sodium level is 124 mEq/L.Which laboratory result will the nurse also expect to see in the patient's chart?

A) Chloride 81 mEq/L
B) Calcium 11.1 mg/dL
C) Phosphate 5.1 mg/dL
D) Magnesium 2.3 mEq/L

Chloride levels are closely associated with sodium levels.When the serum sodium level is low,the chloride level will drop as well.The normal sodium level is 135 to 145 mEq/L so the patient's 124 mEq/L level indicates hyponatremia.The nurse will expect to find the patient's chloride level to be 81,below the 95 to 105 normal range.Hypercalcemia,normal magnesium level,and hyperphosphatemia are not expected with hyponatremia due to vomiting.
