Answer to Question 1

ANS: A
In mitral stenosis, the most common presenting symptoms are dyspnea on exertion and hemoptysis due to pulmonary congestion. The pulmonary congestion is caused by increased left atrial pressure related to the decrease in left atrial emptying. Crackles may be heard at the lung bases but are not present in all patients with pulmonary congestion. Orthopnea may be present because the lungs become more congested in the recumbent position. In addition, atrial fibrillation often develops in patients with mitral stenosis, which, in turn, worsens the pulmonary congestion.

Answer to Question 2

ANS: B
In aortic stenosis, the left ventricle has to work against high resistance and eventually, left ventricular hypertrophy (LVH) develops. The LVH causes an enlarged left ventricle, and the point of maximal impulse located at the fifth intercostal space moves leftward toward the mid-axillary line.
