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

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:

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
