Question 1
2 / 2 pts
According to the lesson, the border of
... [Show More] the myocardium is generally located about 3 cm lateral to the left
of the sternum?
True
Correct!
False
The border of the myocardium is generally located about 6 cm (not 3 cm) lateral to the left of the
sternum.
Question 2

According to the Bates’ Visual Guide video 10.9 Auscultation of Heart Sounds, splitting of S2 is best heard
during inspiration over which area on the chest wall?
Apex
Correct!
Pulmonic
Aortic
Mitral
A split S2 is best heard at the pulmonic valve listening post, as P2 is much softer than A2. Like the S1
heart sound, the S2 sound is described regarding splitting and intensity.

Question 3
2 / 2 pts
According to the lesson, low-pitched sounds of S3 and S4 and the murmur of mitral stenosis are best
heard using what?
The diaphragm of the stethoscope
Correct!
The bell of the stethoscope
The bell and diaphragm are equally effective for this task
The naked ear
Listen throughout the precordium with the diaphragm, pressing it firmly against the chest. The bell is
more sensitive to the low-pitched sounds of S3 and S4 and the murmur of mitral stenosis. Apply the bell
lightly, with just enough pressure to produce an air seal with its full rim. Use the bell at the apex, then
move medially along the lower sternal border. Resting the heel of your hand on the chest like a fulcrum
may help you to maintain light pressure.
Question 4
2 / 2 pts
According to the lesson, the JVP is best assessed from pulsations in the right internal jugular vein, which
is directly in line with the superior vena cava and right atrium?
Correct!
True
False
Estimating the JVP is one of the most important and frequently used skills of physical examination. The
JVP closely parallels pressure in the right atrium, or central venous pressure, related primarily to volume
in the venous system. The JVP is best assessed from pulsations in the right internal jugular vein, which is
directly in line with the superior vena cava and right atrium.

According to the lesson, heart failure can be assessed using the Framingham criteria. Which of the
following findings are major criteria suggestive of heart failure? (Select all that apply)
Correct!
Neck-vein distention
Ankle edema
Correct!
S3 gallop
Correct!
Orthopnea
For establishing a diagnosis of CHF using the modified Framingham Criteria, 2 major criteria or 1 major
and 2 minor criteria must be present. Major criteria are: Paroxysmal nocturnal dyspnea or orthopnea ;
Neck-vein distention; Rales; Cardiomegaly; Acute pulmonary edema; S3 gallop; Increased venous
pressure >16 cm of water; and Hepatojugular reflux. [Show Less]
