Ans: A. Hyperkalemia
Hyperkalemia is defined as a serum potassium concentration greater than approximately 5.0-5.5 mEq/L in adults.
Early ECG changes of hyperkalemia, typically seen at a serum potassium level of 5.5-6.5 mEq/L, include the following: Tall, peaked T waves with a narrow base, best seen in precordial leads. Shortened QT interval. ST-segment depression.
