HEART SOUND

The primary tool used for auscultation is:

• Goniometer

• Stethoscope

• Microscope

• Sphygmomanometer

The first heart sound (S1) is primarily caused by the closure of which valves?

• Atrioventricular valve

• Aortic valve

• Semilunar valve

• Pulmonary valve

Closure of Semilunar valve is heard as ?

• S1 Heart sound

• S2 Heart sound

• S3 Heart sound

• S4 Heart sound

The aortic valve area is best heard at:

• 2nd Intercostal space left sternal boarder

• 2nd Intercostal space right sternal boarder

• 4th Intercostal space left sternal boarder

• None of the above

Identify area of auscultation "Fourth left intercostal space, left sternal border"

The mitral valve area (apex beat) is best heard at:

• 2nd Intercostal space left sternal boarder

• 2nd Intercostal space right sternal boarder

• 5th Intercostal space mid clavicular line

• 4th Intercostal space mid clavicular line

The "lubb" sound is caused by the closure of which valves?

• Aortic and Pulmonary

• Tricuspid and Mitral

• A & B both

• None of the above

Which sound is produce in closure of Semilunar valve

• LUBB

• DUB

• Cardiac Murmur

• None of the above

What is the primary pacemaker of the heart?

• Bundle of his

• AV node

• SA node

• All of the above

What is the correct sequence of electrical conduction through the heart?

• SA node → AV node → Bundle of His → Purkinje fibers → Ventricular myocardium

• AV node → SA node → Bundle of His → Purkinje fibers → Ventricular myocardium

• SA node → Bundle of His → AV node → Purkinje fibers → Ventricular myocardium

• Purkinje fibers → SA node → AV node → Bundle of His → Ventricular myocardium
