ANS: A
Only dilated cardiomyopathy (congestive cardiomyopathy) is characterized by ventricular
dilation and grossly impaired systolic function, leading to dilated heart failure.
PTS: 1 REF: Page 1165
31.
A disproportionate thickening of the interventricular septum is the hallmark of which form
of cardiomyopathy?
a. Dystrophic c. Restrictive
b. Hypertrophic d. Dilated
ANS: B
Only hypertrophic cardiomyopathy is characterized by a thickening of the septal wall,
which may cause outflow obstruction to the left ventricle outflow tract.
PTS: 1 REF: Page 1166
32.
Amyloidosis, hemochromatosis, or glycogen storage disease usually causes which form of
cardiomyopathy?
a. Infiltrative c. Septal
b. Restrictive d. Hypertrophic
ANS: B
Restrictive cardiomyopathy may occur idiopathically or as a cardiac manifestation of
systemic diseases, such as scleroderma, amyloidosis, sarcoidosis, lymphoma, and
hemochromatosis, or a number of inherited storage diseases. This characterization is not
true of the other forms of cardiomyopathy.

Which condition is a cause of acquired aortic regurgitation?
a. Congenital malformation c. Rheumatic fever
b. Cardiac failure d. Coronary artery disease (CAD)
ANS: C
Rheumatic heart disease, bacterial endocarditis, syphilis, hypertension, connective tissue
disorders (e.g., Marfan syndrome, ankylosing spondylitis), appetite suppressing
medications, trauma, or atherosclerosis can cause acquired aortic regurgitation. This
selection is the only available option that is known to cause acquired aortic regurgitation.

Which predominantly female valvular disorder is thought to have an autosomal dominant
inheritance pattern, as well as being associated with connective tissue disease?
a. Mitral valve prolapse c. Tricuspid valve prolapse
b. Tricuspid stenosis d. Aortic insufficiency
ANS: A

Mitral valve prolapse tends to be most prevalent in young women. Studies suggest an
autosomal dominant and X-linked inheritance pattern. Because mitral valve prolapse often
is associated with other inherited connective tissue disorders (e.g., Marfan syndrome,
Ehlers-Danlos syndrome, osteogenesis imperfecta), it is thought to result from a genetic or
environmental disruption of valvular development during the fifth or sixth week of
gestation. This provided history is not associated with any of the other options.

Which disorder causes a transitory truncal rash that is nonpruritic and pink with
erythematous macules that may fade in the center, making them appear as a ringworm?
