An elderly client asks her health care provider if the reason she has developed aortic stenosis is because she drank so much milk as a child growing up on a farm. Which of the following responses is most accurate?
A) "Drinking lots of real milk as a child may have contributed to the damage in your valve."
B) "Atherosclerosis is a long process that eventually results in calcification of heart valves."
C) "This calcification of your aortic valve is more than likely due to an undiagnosed thyroid problem."
D) "More than likely, calcium has left your bones and collected on your aortic valve."
Ans: B
Feedback:
Dystrophic calcification represents the macroscopic deposition of calcium salts in injured tissue. Dystrophic calcification is commonly seen in atheromatous lesions of advanced atherosclerosis, in areas of injury in the aorta and large blood vessels, and in damaged heart valves. For example, calcification of the aortic valve is a frequent cause of aortic stenosis in the elderly. Drinking milk, undiagnosed thyroid problems, and calcium loss from bone causing osteoporosis do not cause damaged heart valves.
