OSCE Cardiovascular Assessment 1

Question 1

During a cardiovascular OSCE station, where is the mitral valve best auscultated?

Accepted Answer

5th intercostal space, midclavicular line

Answer

The mitral valve is best heard at the cardiac apex, located at the 5th intercostal space in the midclavicular line, where the left ventricle is closest to the chest wall.

Question 2

A third heart sound (S3) auscultated in a 58-year-old patient is most likely indicative of which condition?

Accepted Answer

Heart failure with ventricular dilation

Answer

In adults over 40, an S3 (ventricular gallop) is pathological and most commonly indicates heart failure, reflecting rapid ventricular filling in a dilated, poorly compliant ventricle.

Question 3

During JVP assessment, which waveform is characteristically absent in atrial fibrillation?

Accepted Answer

a wave

Answer

The 'a' wave represents atrial contraction; in atrial fibrillation there is no organized atrial contraction, so the 'a' wave is absent from the JVP waveform.

Question 4

A collapsing (water-hammer) pulse on cardiovascular examination is most characteristic of which valvular pathology?

Accepted Answer

Aortic regurgitation

Answer

A collapsing pulse results from a wide pulse pressure caused by backflow of blood into the left ventricle during diastole in aortic regurgitation, producing a rapid rise and fall.

Question 5

Which location is correct for auscultating the aortic valve during a cardiovascular OSCE examination?

Accepted Answer

2nd intercostal space, right sternal edge

Answer

The aortic valve is best auscultated at the 2nd intercostal space, right sternal edge (right upper sternal border), where aortic sounds are transmitted.
