During an automobile accident where the patient is bleeding heavily, which vascular component is the most distensible and can store large quantities of blood that can be returned to the circulation at this time of need?
 
  A)
  Liver and pancreas
  B)
  Kidneys
  C)
  Veins
  D)
  Aorta

Question 2

Which of the following teaching points would be most appropriate for a group of older adults who are concerned about their cardiac health?
 
  A)
  People with plaque in their arteries experience attacks of blood flow disruption at seemingly random times.
  B)
  The plaque that builds up in your heart vessels obstructs the normal flow of blood and can even break loose and lodge itself in a vessel.
  C)
  Infections of any sort are often a signal that plaque disruption is in danger of occurring.
  D)
  The impaired function of the lungs that accompanies pneumonia or chronic obstructive pulmonary disease is a precursor to plaque disruption.

Answer to Question 1

Ans:
C

Feedback:

Compliance refers to the total quantity of blood that can be stored in a given portion of the circulation for each mm Hg rise in pressure. The most distensible of all vessels are the veins, which can increase their volume with only slight changes in pressure. This allows the veins to function as a reservoir for storing large quantities of blood that can be returned to the circulation when it is needed. The liver, pancreas, and kidneys are not vascular components.

Answer to Question 2

Ans:
B

Feedback:

Stable plaque is associated with obstruction of blood flow, while unstable plaque may dislodge and result in thrombus formation. Plaque disruption is noted to correlate with sympathetic events and is not seemingly random; infections and respiratory problems are not noted to be associated with obstruction of blood flow, however.
