Question

An early sign of hyperkalemia is:

A) Flat T waves on an ECG.
B) Widening of the QT interval.
C) Presence of an Osborn wave.
D) Tall, peaked T waves on an ECG.

Answer 1

One of the early signs of hyperkalemia is tall, peaked T waves on an ECG.

Step-by-step explanation:

Hyperkalemia, an elevated potassium blood level, can result in various symptoms including cardiac and central nervous system depression. One of the early signs of hyperkalemia is tall, peaked T waves on an ECG. This abnormality in the T wave morphology reflects changes in the electrical activity of the ventricles and can indicate an increased potassium concentration in the blood.
