Domain 1: Cardiovascular Assessment (10 Questions)
Q1: A 68-year-old male presents with exertional dyspnea and orthopnea. During cardiac
auscultation at the apex with the bell, you hear a low-pitched sound immediately
following S2 during early diastole. The sound is best heard with the patient in the left
lateral decubitus position. Which finding is most consistent with this presentation?
A. S4 gallop rhythm indicating atrial contraction against a non-compliant ventricle
B. Opening snap of mitral stenosis heard in early diastole
C. S3 ventricular gallop indicating volume overload or ventricular dysfunction
[CORRECT]
D. Pericardial friction rub with three components throughout the cardiac cycle
Correct Answer: C
Rationale: The S3 (ventricular gallop) is a low-frequency sound occurring in early
diastole (0.14-0.16 seconds after S2) during the rapid filling phase of ventricles. It is
best auscultated with the bell at the apex while the patient is in the left lateral decubitus
position. The clinical context of exertional dyspnea and orthopnea in an older adult
suggests left ventricular dysfunction or volume overload states (heart failure, mitral
regurgitation).
,Why A is incorrect: S4 occurs immediately before S1 (late diastole/presystole) and
represents atrial contraction against a stiff ventricle, not after S2. The timing described
in the stem (following S2) rules out S4.
Why B is incorrect: An opening snap is a high-pitched, early diastolic sound best heard
at the lower left sternal border or apex, associated with mitral stenosis. It has a
"snapping" quality unlike the dull, thudding quality of S3, and is best heard with the
diaphragm, not the bell.
Why D is incorrect: A pericardial friction rub is a high-pitched, scratchy sound with three
components (atrial systole, ventricular systole, ventricular diastole) heard throughout
the cardiac cycle, not specifically in early diastole. It changes with respiration and
patient position, unlike the fixed timing of S3.
Q2: During assessment of jugular venous pressure (JVP), you observe the right internal
jugular vein with the patient positioned at 45 degrees. The highest point of oscillation is
5 cm above the sternal angle. The patient reports recent weight gain and ankle swelling.
What is the estimated central venous pressure, and what does this indicate?
A. 5 cm H2O; normal JVP with no clinical significance
B. 9 cm H2O; elevated JVP consistent with right ventricular failure or volume overload
[CORRECT]
C. 5 cm H2O; elevated JVP requiring immediate intervention
D. 2 cm H2O; low JVP indicating hypovolemia
Correct Answer: B
,Rationale: The standard formula for estimating central venous pressure is: JVP (cm) =
height above sternal angle + 5 cm (anatomical constant representing the distance from
sternal angle to right atrium). Therefore: 5 cm + 5 cm = 10 cm H2O (acceptable range
8-10 cm). Normal JVP is ≤8 cm H2O. A value of 9-10 cm indicates elevated central
venous pressure. The clinical context of weight gain and peripheral edema supports
volume overload or right heart failure as the underlying pathophysiology.
Why A is incorrect: This answer fails to add the anatomical constant (5 cm). The total
CVP is not merely the observed height above the sternal angle.
Why C is incorrect: While the JVP is elevated, the calculation is incorrect (fails to add 5
cm), and 5 cm H2O would actually be low-normal, not elevated.
Why D is incorrect: The calculation is mathematically incorrect, and the clinical
presentation (weight gain, edema) contradicts hypovolemia, which would present with
flat neck veins and symptoms of dehydration.
Q3: A 55-year-old female with hypertension presents for routine evaluation. During
carotid artery auscultation, you detect a harsh, high-pitched sound in mid-systole that
radiates toward the ear. The sound persists when you ask the patient to hold their
breath. Which assessment finding and action is most appropriate?
A. Venous hum that will disappear when the patient is supine and will not radiate
B. Carotid bruit indicating turbulent blood flow; requires further evaluation for stenosis
[CORRECT]
C. Cardiac murmur of aortic stenosis radiating to the carotids; check for delayed
upstroke
D. Normal physiological sound requiring no further intervention
, Correct Answer: B
Rationale: A carotid bruit is a harsh, high-pitched, systolic sound caused by turbulent
blood flow through a stenotic artery. Key distinguishing features: (1) it persists during
breath-holding (unlike transmitted cardiac murmurs or venous hums), (2) it radiates
toward the ear, and (3) it is best heard over the carotid bifurcation. In patients with
cardiovascular risk factors (hypertension), this finding warrants further evaluation with
carotid duplex ultrasound to assess for atherosclerotic stenosis, which increases stroke
risk.
Why A is incorrect: A venous hum is a continuous, low-pitched sound heard in the
supraclavicular area that diminishes or disappears when the patient is supine or when
gentle pressure is applied to the internal jugular vein. It changes with respiration and
position, unlike the fixed systolic timing of a bruit.
Why C is incorrect: While aortic stenosis murmurs do radiate to the carotids, they are
best heard at the cardiac base (second right intercostal space) and would diminish or
change with breath-holding and Valsalva maneuver. The description specifies the sound
is detected during carotid auscultation as a primary finding, not radiation from the heart.
Why D is incorrect: Carotid bruits are never normal physiological sounds. They indicate
pathological turbulent flow requiring diagnostic workup.
Q4: You are auscultating the heart of a 45-year-old patient and hear S1 and S2 clearly.
You then detect an extra sound in late diastole immediately preceding S1. The patient
has a history of poorly controlled hypertension and diabetes. Which physiological event
produces this sound?
A. Rapid ventricular filling during early diastole producing an S3
