Cardiac Auscultation Quiz

Mitral valve closure produces the 'lub' sound in cardiac auscultation.

S1 represents the closure of the mitral and tricuspid valves in cardiac auscultation.

Aortic valve closure is responsible for the 'dub' sound in cardiac auscultation.

The aortic valve is typically best heard at the left sternal border in the 4th intercostal space.

Aortic valve closure contributes to the 'dub' sound heard during cardiac auscultation.

Aortic regurgitation murmur is typically heard during ventricular systole.

Aortic regurgitation is the most common cause of an early diastolic murmur.

Mitral regurgitation is characterized by a high-pitched, blowing holosystolic murmur.

A physiological flow murmur is the most common cause of a mid-systolic ejection murmur in children and young adults.

A mitral valve prolapse murmur increases with standing.

Standing from a squatting position can help differentiate innocent flow murmurs from pathological murmurs in children.

Valsalva maneuver can accentuate a mitral valve prolapse murmur.

The mitral valve area is best auscultated in the fifth intercostal space, left midclavicular line.

A pericardial friction rub is heard best with the patient leaning forward.

Mitral regurgitation is the most likely cause of an early systolic murmur that radiates to the neck in a patient with a history of rheumatic fever.

A continuous murmur is expected in patent ductus arteriosus.

Aortic regurgitation is the most common cause of an early diastolic murmur in an elderly patient with a history of hypertension.
