A nurse is reviewing the laboratory test results of a client who is receiving diuretic therapy. The nurse determines that the client is at risk for electrolyte imbalance based on which results? Select all that apply
A) Potassium 4.5 mEq/L
B) Sodium 139 mEq/L
C) Magnesium 2.0 mEq/L
D) Sodium 124 mEq/L
E) Potassium 2.9 mEq/L
Ans: D, E
Feedback:
Sodium levels below 132 mEq/L, such as 124 mEq/L, or above 145 mEq/L would indicate an imbalance. Potassium imbalances would occur with levels below 3.0 mEq/L, such as 2.9 mEq/L, or above 5 mEq/L. A magnesium level of 2.0 mEq/L is within the normal range of 1.5 to 2.5 mEq/L.
