A 55-year-old male who is beginning to take a statin drug for his hypercholesterolemi a is discussing cholesterol and its role in health and illness with his physician.
 
  Which of the following aspects of hyperlipidemia would the physician most likely take into account when teaching the patient?
  A)
  Hyperlipidemia is a consequence of diet and lifestyle rather than genetics.
  B)
  HDL cholesterol is often characterized as being beneficial to health.
  C)
  Cholesterol is a metabolic waste product that the liver is responsible for clearing.
  D)
  The goal of medical treatment is to eliminate cholesterol from the vascular system.

Question 2

A 72-year-old female has been told by her physician that she has a new heart murmur that requires her to go visit a cardiologist.
 
  Upon examination, the cardiologist informs the patient that she has aortic stenosis. After the cardiologist has left the room, the patient asks, What caused this aortic stenosis to happen now? The clinic nurse responds,
  A)
  Heart murmurs result from tumultuous flow through a diseased heart valve that is too narrow and stiff. This flow causes a vibration called a murmur.
  B)
  Aortic stenosis is commonly seen in elderly patients. Basically, there is a blockage in the valve that is causing blood to pool, causing decreased velocity of flow.
  C)
  This is caused by a tear in one of the papillary muscles attached to the valve. They can do a procedure where they thread a catheter into the heart and reattach the muscle ends.
  D)
  Because of the high amount of energy it takes to push blood through the aortic valve to the body, your valve is just had to work too hard and it is weakening.

Answer to Question 1

Ans:
B

Feedback:

Because it transports cholesterol back to the liver from the periphery, HDL is associated with increased health and lowered risk of atherosclerosis. Genetics play a role in hyperlipidemia, and it is inaccurate to characterize cholesterol as a waste product. Cholesterol is necessary for several physiological processes, and complete elimination is neither realistic nor desirable.

Answer to Question 2

Ans:
A

Feedback:

Heart murmur results from turbulent flow through a diseased heart valve that may be too narrow, too stiff, or too floppy. This turbulent flow causes a vibration called a murmur.
