c. pericarditis
d. an incompetent aortic valve
- Correct Answer - c. pericarditis
What is the outcome for many aortic aneurysms?
- Correct Answer - rupture and hemorrhage
Phlebothrombosis is more likely to cause pulmonary emboli than is
thrombophlebitis because:
a. platelets attach to the inflamed wall
b. thrombus forms in a vein and is asymptomatic
c. leg cramps require massage
d. systemic signs of inflammation require treatment
- Correct Answer - b. thrombus forms in a vein and is asymptomatic
How is shock defined?
a. failure of the heart to supply sufficient blood to body cells
b. general hypoxia causing damage to various organs
,c. decreased circulating blood and tissue perfusion
d. loss of blood causing severe hypoxia
- Correct Answer - c. decreased circulating blood and tissue perfusion
When does shock follow myocardial infarction?
a. The stress response causes general vasodilation.
b. Fluid is lost into ischemic tissues.
c. Heart valves are damaged.
d. A large portion of the myocardium is damaged.
- Correct Answer - d. A large portion of the myocardium is damaged.
What are the early signs of circulatory shock?
1. pale moist skin
2. loss of consciousness
3. anxiety and restlessness
4. rapid strong pulse
a. 1, 2
b. 1, 3
c. 1, 4
d. 3, 4

What indicates compensation for shock?
a. increased heart rate and oliguria
b. lethargy and decreased responsiveness
c. warm, dry, flushed skin
, d. weak, thready pulse
- Correct Answer - a. increased heart rate and oliguria
Why does neurogenic (vasogenic) shock result from systemic
vasodilation?
a. increased peripheral resistance and less blood in the microcirculation
b. increased permeability of all the blood vessels leading to hypovolemia
c. slower, less forceful cardiac contractions
d. increased capacity of the vascular system and reduced venous return
- Correct Answer - d. increased capacity of the vascular system and
reduced venous return
What is a prolonged period of shock likely to cause?
a. damage and increased permeability of pulmonary capillaries
b. increased permeability of the glomerular capillaries of the kidneys

d. Increased systemic vasoconstriction
- Correct Answer - a. damage and increased permeability of pulmonary
capillaries
