An atheroma develops initially from ____ a. venous thrombus formation b. repeated vasospasm c. an area of endothelial injury d. a torn arterial wall and blood clots Which of the following would likely occur from atherosclerosis in the iliac arteries? a. weak peripheral pulses proximal to the occlusion b. skin of the legs is warm to touch distal to the occlusion c. pallor when the legs are dangling d. rubor when the legs are dangling The basic pathophysiological change associated with essential hypertension is: a. recurrent inflammation and fibrosis in peripheral arteries b. degeneration and loss of elasticity in peripheral arteries c. development of atherosclerotic plaques in large arteries d. increase systemic afterload from arterial vasoconstriction A drug classified as a vasodilator will do which of the following? a. decrease afterload b. decrease tissue perfusion c. increase preload d. increase peripheral vascular resistance what is the cause of oral ulcerations and delayed healing occurring with any severe anemia? a. lack of folic acid for DNA synthesis b. deficit of oxygen for epithelial cell regeneration c. elevated bilirubin levels in the blood and body fluids d. frequent microinfarcts in the tissues Phlebothrombosis is more likely to cause pulmonary emboli than is thrombophlebitis because: a. it results in systemic signs of inflammation b. the thrombus is usually asymptomatic c. there is decreased cardiac output d. platelets attach to the inflamed vein wall. Which of the following is an early sign of circulatory shock? a. weak thready pulse b. rapid respiratory rate c. restlessness and anxiety d. loss of consciousness The primary goal of the compensatory mechanism in shock is to: a. increase capillary permeability b. decrease the workload of the heart c. increase cardiac output d. decrease the heart rate Why does neurogenic (vasogenic) shock result from systemic vasodilation? a. slower and less forceful myocardial contractions b. increased capacity of the vascular system c. increased permeability of all systemic blood vessels d. increased peripheral resistance in microcirculation
