Question 1 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
Correct Answer: A
Rationale: The correct answer is A: Abnormally prominent U wave. Hypokalemia leads to low potassium levels, affecting cardiac function. This can manifest as U wave prominence on EKG due to delayed repolarization of ventricles. Inverted P wave (choice
B) is seen in conditions like atrial ischemia, not specific to hypokalemia. Elevated ST segment (choice
C) indicates myocardial injury, not typically seen in hypokalemia. Wide QRS (choice
D) is seen in conditions like bundle branch blocks, not specific to hypokalemia. The other choices are not directly related to hypokalemia and are therefore incorrect.
