Cardiac Question #14


A nurse is caring for a client with venous disease in the lower extremities and is ordered radiologic testing. The nurse educates the client on which exam will likely be ordered for lower venous disease?


  1. Duplex ultrasonography
    • Rationale:
  2. Echocardiography
    • Rationale:
  3. Positron emission tomography (PET)
    • Rationale:
  4. Radiography
    • Rationale:



The duplex ultrasonography will determine how blood moves through the peripheral vessels by use of traditional ultrasonography with Doppler sonography. It helps with venous insufficiency to map out normal and abnormal venous pathways and to identify levels of obstruction of blood flow. Echocardiography examines the heart. PET and radiography are not determined to be the gold standard for determining evaluation of venous insufficiency.
