  b. Mitral stenosis
  c. Aortic regurgitation

Question 2

A 72-year-old has a history of hypertension and atherosclerosis. An echocardiogram reveals backflow of blood into the left ventricle. Which of the following is the most likely diagnosis documented on the chart?

Answer to Question 1

ANS: C
Aortic regurgitation is manifested by widened pulse pressure resulting from increased stroke volume and diastolic backflow. Mitral regurgitation is manifested by heart failure.
Mitral stenosis is manifested by pulmonary edema and heart failure. Aortic stenosis is manifested by narrowed pulse pressure.

Answer to Question 2

ANS: C
Aortic regurgitation would allow backward flow of blood into the left ventricle. Mitral regurgita-tion would allow backward flow of blood into the left atrium. Mitral stenosis would impede blood flow from the right atrium into the right ventricle. Aortic stenosis would impede blood flow into the aorta.
