Question 1 of 5
The nurse reviews a client's electrolyte results and notes that the potassium level is 5.4 mEq/L. What would the nurse look for on the cardiac monitor as a result of this laboratory value?
Correct Answer: A
Rationale: The correct answer is A: Narrow peaked T waves. High potassium levels can lead to hyperkalemia, causing changes on the ECG such as narrow peaked T waves. Potassium affects cardiac conduction, and elevated levels can disrupt the normal electrical activity of the heart, resulting in T wave changes. ST elevation (
B) is typically associated with myocardial infarction, not hyperkalemia. Peaked P waves (
C) are seen in conditions like right atrial enlargement. Prominent U waves (
D) are typically seen with hypokalemia.
