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: B
Rationale: The correct answer is B: Prominent U wave. Hypokalemia, or low potassium levels, can cause the U wave to become more prominent on an EKG strip. This is due to delayed repolarization of the ventricles. A flat T wave (choice
A) is typically associated with ischemia or infarction. ST elevation (choice
C) is often seen in conditions like myocardial infarction. A wide QRS complex (choice
D) is indicative of conduction abnormalities.
Choices E, F, and G are not relevant to the interpretation of hypokalemia on an EKG strip.
