NCLEX RN Exam Questions
Question 1 of 5.
A client with IDDM is given IV insulin for a blood glucose level of 520 mg/dL. Life-threatening complications may occur initially, so the nurse will monitor him closely for serum:
A. Chloride level of 99 mEq/L
B. Sodium level of 136 mEq/L
C. Potassium level of 3.1 mEq/L
D. Potassium level of 6.3 mEq/L
Explanation: When diabetic ketoacidosis exists, intracellular dehydration occurs and potassium leaves the cells and enters the vascular system, thus increasing the serum level beyond an acceptable range. When insulin and fluids are administered, cell walls are repaired and potassium is transported back into the cells. Normal serum potassium levels range from 3.5-5.0 mEq/L.
