David suffers from a re-gurgitating mitral valve. this condition would cause:.a) increased cardiac output from the right ventricle. b) edema in the lower limbs. c) fluid congestion in the lungs. d) decreased heart rate. e) a bruit sound when ausculated with a stethoscope.

The correct answer is: E) a bruit sound when auscultated with a stethoscope.

Explanation:

Mitral valve regurgitation is a condition in which the mitral valve - responsible for the blood flow from the left atrium to the left ventricle - doesn't close as tightly as it should, which can result in backward blood flow. If the condition worsens, this defect can lead to heart failure.

Mitral valve regurgitation may not have symptoms at first but, as the condition progresses, shortness of breath, fatigue, and palpitations can occur. When auscultated with a stethoscope, a bruit sound can be heard, which corresponds to the abnormal blood flow that is occurring.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
