• Formation of arterial plaques

• Formation of venous thrombosis

• Regulation of blood pressure

• Oxygen transport in blood

Which of the following is NOT a component of Virchow's triad?

• Venous stasis

• Vessel wall injury

• Hypercoagulable state

• Blood oxygenation

What determines the formation of thrombosis according to the text?

• Balance of blood pressure and heart rate

• Imbalance of clotting factors, coagulation inhibitors, and fibrinolytic system

• Levels of red and white blood cells

• Amount of oxygen in the blood

What is the effect of venous stasis on clotting factors?

• Decreases exposure to clotting factors

• Increases exposure to clotting factors

• Has no effect on clotting factors

• Eliminates clotting factors

What can result from vessel wall injury?

• Enhanced immune response

• Improved blood flow

• Affects the body’s normal thrombolytic system

• Decreased risk of infection

Which of the following is associated with hypercoagulability?

• Increased physical activity

• Genetic factors

• Low blood pressure

• Dehydration

What is a potential cause of vessel wall injury?

• High cholesterol

• Catheter injury or trauma

• Low blood sugar

• Vitamin deficiency

What characteristic of an acute thrombus can be identified using modern imaging equipment?

• It is always invisible

• It is always hyperechoic

• It can be hypoechoic, hyperechoic, or have areas with both

• It is always attached to the vessel wall

How is an acute thrombus typically attached to the vessel wall?

• Firmly attached

• Poorly attached

• Not attached at all

• Strongly attached

What is the texture of an acute thrombus?
