Question

Which of the following is indicative of an EKG change in a case of hypokalemia?

A. Widened QRS complex and prolonged PR interval
B. Prolonged ST interval and Widened T-wave
C. Tall T-waves and depressed ST segment
D. ST depression and inverted T-wave

Answer 1

The correct answer is A. Widened QRS complex and prolonged PR interval. In a case of hypokalemia, the EKG changes observed include a widened QRS complex and prolonged PR interval.

Step-by-step explanation:

The correct answer is A. Widened QRS complex and prolonged PR interval. In a case of hypokalemia, which is low levels of potassium in the blood, one of the characteristic EKG changes is a widened QRS complex due to delay in ventricular conduction. Additionally, there may be a prolonged PR interval due to slowed atrioventricular conduction. These changes are indicative of the electrical disturbance in the heart caused by hypokalemia.
