Therefore, the nurse should suspect hypokalemia. The incidence of potentially lethal ventricular dysrhythmias is increased in hypokalemia. The nurse should immediately assess the client's vital signs and cardiac status for signs of hypokalemia. The nurse should also check the client's most recent serum potassium level and then contact the primary health care provider to report the findings and obtain prescriptions to treat the hypokalemic state.
