Question

The nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.7. Which finding would the nurse expect to note on the ECG as a result of the lab value?

ST depression
Inverted T wave
Prominent U wave
Tall peaked T waves

Answer 1

Tall peaked T waves

Step-by-step explanation:

Hyperkalemia may result in ECG changes, including peaked T wave, flattened P wave, prolonged PR interval, ST depression, and prolonged QRS duration. Since hypokalemia also causes ST depression, we can eliminate it as well.
