Question 1 of 5
A nurse is reviewing the laboratory values of a patient receiving total parenteral nutrition (TPN). The glucose is 72 mg/dL,chloride is 100 mEq/L,sodium is 138 mEq/L,and potassium is 3.0 mEq/L. What action should the nurse plan to take?
Correct Answer: C
Rationale: The correct answer is C: Request a potassium replacement. The patient's potassium level of 3.0 mEq/L is below the normal range (3.5-5.0 mEq/L), indicating hypokalemia.
Total parenteral nutrition (TPN) can cause electrolyte imbalances, including hypokalemia. Potassium is essential for proper muscle function, including the heart. Hypokalemia can lead to cardiac arrhythmias and muscle weakness.
Therefore, the nurse should plan to request a potassium replacement to prevent potential complications. Administering glucagon (choice
A) would not address the potassium deficiency. Discontinuing the TPN infusion (choice
B) may not be necessary if the issue is solely related to potassium levels. Checking for a positive Chvostek's sign (choice
D) is not relevant to addressing hypokalemia.
