Answer

Physical findings are often within the reference range. Abnormal findings may reflect the underlying disorder. Severe hypokalemia may manifest as bradycardia with cardiovascular collapse. Cardiac arrhythmias and acute respiratory failure from muscle paralysis are life-threatening complications that require immediate diagnosis.
