Practice Quiz - Superficial Lower Limb
    Below are written questions from previous quizzes and exams. Click here for a Practical Quiz - old format or Practical Quiz - new format.

  1. Following a car accident in which the patient received a deep laceration on the medial side of his right knee, the patient notices numbness along the medial side of his right leg and foot. He has no motor deficit. The nerve which appears to have been injured is the:
    femoral nerve
    saphenous nerve
    sural nerve
    superficial fibular nerve
    deep fibular nerve
  2. A 'saphenous vein cut-down' is a procedure used to locate the great saphenous vein at the ankle. To find this vein, the skin would be incised:
    anterior to the lateral epicondyle
    posterior to the medial epicondyle
    anterior to the medial malleolus
    posterior to the lateral malleolus
    over the base of the fifth metatarsal
  3. While doing a physical examination on a young boy, you noticed an enlarged superficial inguinal lymph node. The patient indicated that he has recently sustained an infected skin wound in the:
    anterior abdominal wall above the umbilicus.
    anterior chest wall.
    skin of the lower limb.
    upper back.
  4. A patient with a diabetic ulcer in the anterior midline of the ankle region experienced loss of cutaneous sensation on the dorsal surface of the foot. Which nerve was most likely damaged?
    Femoral
    Lateral sural cutaneous
    Saphenous
    Superficial fibular
    Sural
  5. A construction worker, who wears a heavy work belt all day on the job, notices a tingling sensation on the anterolateral surface of his thigh. This is most likely a condition called:
    compartment syndrome
    cryptorchidism
    hydrocoele
    meralgia parasthetica
    thrombophlebitis
  6. A saphenous cutdown is a surgical procedure that involves cutting through the skin to locate the greater saphenous vein in order to insert a catheter or cannula. You can find the vein as it passes ___________________ with the saphenous nerve.
    Anterior to the medial epicondyle
    Anterior to the medial malleolus
    Through the saphenous opening
    Tributaries to the posterior tibial vein
    Subcutaneous branches of the posterior tibial artery
  7. A cashier develops painful and tortuous varicose veins in her lower limb. Her doctor explains that prolonged standing at her job led to failure of the valves in the:
    deep femoral vein
    great saphenous vein
    lesser saphenous vein
    perforating veins
    popliteal vein
  8. Your patient complains of pain on her calf. Upon inspection, you find tortuous, dilated vessels lying subcutaneously on the posterior aspect of her leg. These vessels are most likely:
    Tributaries to the greater saphenous vein
    Tributaries to the lesser saphenous vein
    Perforating veins
    Through the iliotibial tract
    Through the popliteal fascia
  9. A 50-year-old female patient has large varicose veins located primarily on the posterior aspect of her calf. These veins are most likely direct tributaries to the:
    great saphenous vein
    sural vein
    small saphenous vein
    femoral vein
    dorsal venous arch
  10. You are in the clinic when a patient presents with varicose saphenous veins in her lower limb. The attending physician asks where the venous valves are located that are defective and cause this condition. Having just studied a clinical case in that regard, you respond. "The valves in the:
    deep veins."
    perforating veins."
    superficial veins."
    venae commitantes."
  11. Subcutaneous venous varicosities were observed in the anteromedial thigh. The vein involved is likely to be the:
    Femoral
    Greater saphenous
    Lesser saphenous
    Popliteal
    Superficial external pudendal
  12. The distal part of the lesser saphenous vein was mobilized for grafting. Following the operation, the patient complained of numbness (loss of cutaneous sensation) on the distal lateral side of the leg and the lateral side of the foot. What nerve was damaged during the operation?
    Deep fibular (peroneal)
    Posterior femoral cutaneous
    Saphenous
    Superficial fibular (peroneal)
    Sural
  13. Varicosities in the subcutaneous veins of the medial thigh were observed at physical examination. The vein involved was most likely the:
    Femoral.
    Greater saphenous.
    Lesser saphenous.
    Popliteal.
    Pudendal.
  14. The lesser saphenous vein was mobilized for grafting. Following the surgery, the patient complained of a loss of cutaneous sensation at the distal posterolateral side of the leg, lateral side of the foot and small toe. What nerve was damaged during the operation?
    common fibular (peroneal)
    saphenous
    superficial fibular (peroneal)
    sural
    tibial
  15. Competency of venous valves in a patient with severe crural varicose veins was tested as follows: The superficial veins were emptied by elevating the limb and then they were compressed with a band just below the saphenous opening in the proximal thigh. When the patient quickly stood up, filling of the superficial veins took more than 30 seconds. The delayed filling of the superficial veins demonstrates that the valves of the:
    deep (central) veins are competent
    deep (central) veins are incompetent
    perforating veins are competent
    perforating veins are incompetent
    superificial veins are competent
  16. A needle biopsy of the sural nerve resulted in the formation of a hematoma. Which of the following veins closely adjacent to the nerve was accidently injured?
    accessory saphenous
    femoral
    greater saphenous
    lesser saphenous
    superficial external pudendal
