A physician wishes to place a central line (a catheter used to repeatedly administer drugs such as chemotherapy drugs into a patient\'s circulatory system) into the right atrium of the patient\'s heart. To do this, the physician will place the catheter into the basilic vein just superior to where it branches from the median cubital vein. The physician will then guide the catheter along the venous system until it reaches the right atrium, list, in order, the v through which the central line passes as it travels from the basilic vein to the right atrium of the heart. _________ ___________ _________ _________ Right atrium __________ After the central line was passed (question 43), it pinched off and failed to work when the patient held a heavy weight in her hand and the inferior movement of her clavicle compressed the central line with in the subclavian vein. The physician decided to remove the central line from the basis and place another central line into the internal jugular vein(IJV).The IJV provides a more direct route to the heart and avoids the problem of a pinch-off. List the veins, in order, through which the central line passes as it travels from the internal jugular vein to the right atrium of the heart ___________ ___________ ___________

Solution

43. Assuming that the catheter is inserted in the basilic vein of left hand, the course of the catheter is...

a.left axillary vein

b.left subclavian vein

c.left brachicephalic vein

d.Superior venacava

e. right atrium

Blood from all the upper extremeties drain into the superior venacava which drains into the right atrium.

44. a. Internal jugular vein

      b. right brachiocephalic vein

      c.superior vena cava

       d.right atrium
