RN 231 Quiz I
1. 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?

and heart disease. For a client who has hypokalemia, the nurse should monitor the EKG strip for
a flattened T wave, prolonged PR interval, prominent U wave, or ST depression.
B. Elevated ST segment
Rationale: The nurse should identify ST depression as an indication of hypokalemia.
C. Wide QRS
Rationale: The nurse should identify a widened QRS as an indication of hyperkalemia.
D. Inverted P wave
