In the process of escaping from T. rex in Jurassic Park the heroine punctures the skin on the medial side of her wrist on a spiny bush. A few days later, due to the toxin, an infection is seen spreading up the medial side of her arm along the large cutaneous vein extending from the dorsum of her hand to the medial side of her arm. The vein involved is the:
basilic brachial cephalic median cubital ulnar

back of his head in the occipital area chest, just above the nipple lateral side of arm lateral forearm dorsal side of hand
While you are stitching up his hand, he notes that you did not have to give him an anesthetic
since the area between his thumb and index finger on the dorsal side was already numb. Which nerve must have been injured (most likely by the fracture of his wrist) for this area to be numb?
lateral antebrachial cutaneous medial antebrachial cutaneous median superficial radial superficial ulnar

Basilic Cephalic Median antebrachial Median cubital Radial
During insertion of an IV cannula in the median cubital vein, the patient suddenly lost feeling on the radial side of the forearm. What nerve was injured?
Lateral antebrachial cutaneous Medial antebrachial cutaneous Musculocutaneous Posterior antebrachial cutaneous Superficial radial nerve
After trying to throw a curve ball, a pitcher lost sensation from the tip of the little finger. This indicates injury to which nerve?
Radial Median Ulnar Musculocutaneous Medial antebrachial cutaneous
While having an IV needle inserted into the cephalic vein of the forearm, the patient suddenly screamed in pain and felt tingling in part of the skin of the forearm supplied by the nerve accompanying the vein. What nerve was injured?
Posterior antebrachial cutaneous Lateral antebrachial cutaneous Medial antebrachial cutaneous Musculocutaneous Superficial radial
Because of scarring of a patient's median cubital vein, the technician chooses to insert an infusion needle into her basilic vein at the level of the medial epicondyle. Despite the certainty that the needle does not pass through the deep (investing) fascia, there is still a chance that it might nick or impale which of the following?
Brachial artery Lateral antebrachial cutaneous nerve Medial antebrachial cutaneous nerve Median nerve Radial nerve
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
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
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.
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
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
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
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
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
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
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."
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
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
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.
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
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
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
