Go to Quiz Page

Which of the following heart sounds is associated with the closure of the mitral valve?

Explanation

First heart sound; closure of mitral and tricuspid valves.

A diastolic murmur is heard best:

During diastole

Explanation

Diastolic murmurs occur during heart relaxation (diastole).

What is the most common cause of aortic regurgitation?

Infective endocarditis

Explanation

Infection of heart valves leading to valve damage.

Which of the following maneuvers can increase the intensity of mitral valve prolapse murmur?

Valsalva maneuver

Explanation

Decreased venous return to the heart increases the prolapse.

Which of the following is a characteristic feature of aortic stenosis murmur?

High-pitched, crescendo-decrescendo murmur

Explanation

Harsh, diamond-shaped murmur during ventricular ejection.

Which valve disorder is characterized by the narrowing of the aortic valve?

Aortic stenosis

Explanation

Narrowing of the aortic valve, leading to reduced blood flow from the heart.

The presence of a mid-systolic click is typically associated with which valve disorder?

Mitral valve prolapse

Explanation

Valve leaflets billow back into the left atrium during systole, causing the click.

A continuous machinery-like murmur is characteristic of which condition?

Patent ductus arteriosus

Explanation

Failure of ductus arteriosus to close after birth.

In which condition would you typically hear an opening snap followed by a diastolic rumble on auscultation?

Mitral stenosis

Explanation

Narrowed mitral valve restricts blood flow during diastole.

#10

What is the classic triad of symptoms associated with aortic stenosis?

Dyspnea, angina, syncope

Explanation

Shortness of breath, chest pain, fainting due to reduced blood flow.

#11

In which position is the murmur of mitral stenosis usually accentuated?

Left lateral decubitus position

Explanation

Murmur intensifies when lying on the left side.

#12

Which of the following maneuvers can help differentiate between innocent and pathologic murmurs in children?

Standing from squatting position

Explanation

Change in murmur intensity with position indicates pathology.

#13

Which of the following is a characteristic feature of tricuspid regurgitation murmur?

Holosystolic murmur

Explanation

Murmur heard throughout systole due to backflow through the tricuspid valve.

#14

Which maneuver can help differentiate between mitral valve prolapse and hypertrophic cardiomyopathy murmurs?

Handgrip maneuver

Explanation

Decreased preload increases mitral valve prolapse murmur.

#15

Which of the following maneuvers decreases the intensity of mitral valve prolapse murmur?

Inspiration

Explanation

Decreased venous return to the heart reduces prolapse.
