U waves-rationale: a serum potassium level lower than 3.5 meq/l indicates hypokalemia. potassium deficit is a common electrolyte imbalance and is potentially life-threatening. electrocardiographic changes include inverted t waves, st segment depression, and prominent u waves. absent p waves are not a characteristic of hypokalemia.test-taking strategy: from the information in the question, you need to determine that the client is experiencing hypokalemia. from this point, you must know the electrocardiographic changes that are expected when hypokalemia exists. if you had difficulty with this question, review the electrocardiographic changes that occur in hypokalemia.
