A client has been diagnosed with mitral valve stenosis following his recovery from rheumatic fever. Which of the following teaching points would be most accurate to convey to the client?
A)
"The normal tissue that makes up the valve between the right sides of your heart has stiffened."
B)
"Your mitral valve isn't opening up enough for blood to flow into the part of your heart that sends blood into circulation."
C)
"Your heart's mitral valve isn't closing properly so blood is flowing backward in your heart and eventually into your lungs."
D)
"The valve between your left ventricle and left atria is infected and isn't allowing enough blood through."
Ans:
B
Feedback:
Mitral valve stenosis represents the incomplete opening of the mitral valve during diastole with left atrial distention and impaired filling of the left ventricle. It does not exist in the right side of the heart, and the problem is associated primarily with improper ventricular filling and with pulmonary backflow only secondarily. Although it is often caused by infection, it is not an infectious process of the valve per se.
