Assessment of Cardiac Heart Sounds and Cardiac Murmurs

Question 1

KNOW THIS WITHOUT A DOUBT

Answer 1

Cool beans

Question 2

In supine patients, the diameter of PMI should be between 1-2.5 cm. A PMI greater than 2.5cm would indicate which of the following?

A. Right Ventricular Hypertrophy

B. Left Ventricular Hypertrophy

C. COPD

D. Heart Failure with an Acute MI

Answer 2

Left Ventricular Hypertrophy

think about the anatomy

Question 3

In which of the following disorders might you see the PMI in the xiphoid process or epigastric area?

A. Right Ventricular Hypertrophy

B. Left Ventricular Hypertrophy

C. COPD

D. Heart Failure with an Acute MI

Answer 3

C. COPD

Question 4

T/F: Displacement of the PMI medial to the midclavicular line or less than 10 cm medial to the midsternal line occurs in LVH and also in ventricular dilation from MI or heart failure

Answer 4

False;

True: Displacement of the PMI lateral to the midclavicular line or greater than 10 cm medial to the midsternal line occurs in LVH and also in ventricular dilation from MI or heart failure

Question 5

Which of the following correctly explains the S3 heart sound?

A. Abrupt deceleration of inflow across the tricuspid valve

B. Abrupt deceleration of inflow across the mitral valve

C. Increased left ventricular end diastolic stiffness

D. Abrupt acceleration of outflow across the mitral valve

E. Increased right ventricular end diastolic stiffness

Answer 5

Abrupt deceleration of inflow across the mitral valve

Question 6

Which of the following correctly explains the S4 heart sound?

A. Increased left ventricular end systolic stiffness

B. Abrupt deceleration of inflow across the mitral valve

C. Increased left ventricular end diastolic stiffness

D. Abrupt acceleration of outflow across the mitral valve

E. Increased right ventricular end diastolic stiffness

Answer 6

C. Increased left ventricular end diastolic stiffness

Question 7

T/F: During diastole, pressure in the blood-filled left atrium slightly exceeds that in the relaxed left ventricle

Answer 7

True

Question 8

What are the 4 diastolic murmurs Dr. Tyler shared during lecture?

Answer 8

Aortic Insufficiency

Pulmonic Regurgitation

Tricuspid and Mitral Stenosis

PR-AI-MS

Question 9

Yeah get comfortable with this

Answer 9

Dope

Question 10

What would result in terms of timing or intensity in each of the following when the PT is put into a squatting position?

Mitral Valve Prolapse- Length of murmur:

Hypertrophic Cardiomyopathy- Intensity of murmur:

Aortic Stenosis- Intensity of murmur:

Answer 10

Mitral Valve Prolapse- Length of murmur: increase

Hypertrophic Cardiomyopathy- Intensity of murmur: decrease

Aortic Stenosis- Intensity of murmur: increase

Question 11

What would result in terms of timing or intensity in each of the following when the PT is put into a standing valsava position?

Mitral Valve Prolapse- Length of murmur:

Hypertrophic Cardiomyopathy- Intensity of murmur:

Aortic Stenosis- Intensity of murmur:

Answer 11

Mitral Valve Prolapse- Length of murmur: increase

Hypertrophic Cardiomyopathy- Intensity of murmur: increase

Aortic Stenosis- Intensity of murmur: decrease
