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. In hypokalemia, low potassium levels can lead to U wave prominence on an EKG. The U wave becomes more visible and prominent due to delayed repolarization of the Purkinje fibers. This is a classic EKG finding in hypokalemia. Tachycardia (choice
B) is a non-specific finding and can be caused by various conditions. Flattened P wave (choice
C) is seen in hyperkalemia, not hypokalemia. Prolonged PR interval (choice
D) is more indicative of first-degree heart block or other conduction abnormalities, not specifically hypokalemia.
