SECTION 1: CARDIOVASCULAR PATHOPHYSIOLOGY
QUESTIONS 1-40
Q1. A patient with left-sided heart failure presents with pulmonary crackles and
dyspnea. Which pathophysiologic mechanism is primarily responsible for these
findings?
A) Systemic venous congestion
B) Increased pulmonary capillary hydrostatic pressure
C) Decreased cardiac output
D) Peripheral vasodilation
Answer: B) Increased pulmonary capillary hydrostatic pressure
Rationale: Left-sided heart failure causes increased pressure in the left ventricle,
which backs up into the left atrium and pulmonary veins. This increases
pulmonary capillary hydrostatic pressure, leading to fluid transudation into the
alveoli and interstitial spaces. This causes pulmonary congestion, which manifests
as crackles, dyspnea, and orthopnea. Systemic venous congestion is characteristic
of right-sided heart failure. Decreased cardiac output is a consequence but not
the direct cause of pulmonary findings. Peripheral vasodilation is not a primary
mechanism in heart failure.
Q2. A patient presents with jugular venous distension, peripheral edema, and
hepatomegaly. Which type of heart failure is most likely?
A) Left-sided heart failure
B) Right-sided heart failure
C) High-output heart failure
D) Diastolic heart failure
Answer: B) Right-sided heart failure
1
,Rationale: Right-sided heart failure causes systemic venous congestion because
the right ventricle cannot pump blood effectively into the pulmonary circulation.
This leads to jugular venous distension (JVD), peripheral edema (fluid
accumulation in dependent areas), and hepatomegaly (congestive hepatopathy).
Left-sided heart failure causes pulmonary congestion. High-output heart failure is
characterized by increased cardiac output and warm extremities. Diastolic heart
failure involves impaired ventricular filling with preserved ejection fraction.
Q3. Which of the following is a hallmark finding in cardiogenic shock?
A) Warm, dry skin
B) Hypotension with tachycardia
C) Jugular venous distension
D) Bounding pulses
Answer: B) Hypotension with tachycardia
Rationale: Cardiogenic shock is characterized by pump failure, leading to
inadequate cardiac output and tissue hypoperfusion. Hypotension (systolic BP <
90 mmHg) and tachycardia (compensatory mechanism) are hallmark findings.
Warm, dry skin and bounding pulses are seen in distributive shock (sepsis,
anaphylaxis). Jugular venous distension may occur but is not the hallmark finding.
Q4. A patient with a history of hypertension develops left ventricular
hypertrophy. This adaptation is primarily a response to:
A) Increased preload
B) Increased afterload
C) Decreased contractility
D) Decreased heart rate
Answer: B) Increased afterload
Rationale: Left ventricular hypertrophy (LVH) is a compensatory response to
chronic pressure overload (increased afterload). Hypertension increases systemic
vascular resistance, requiring the left ventricle to work harder to eject blood. The
myocytes undergo hypertrophy to maintain cardiac output. Increased preload
causes ventricular dilation (not hypertrophy). Decreased contractility and heart
rate would not trigger hypertrophic adaptation.

,Q5. Which valve lesion is most commonly associated with rheumatic fever?
A) Aortic stenosis
B) Mitral stenosis
C) Tricuspid regurgitation
D) Pulmonic stenosis
Answer: B) Mitral stenosis
Rationale: Rheumatic fever is an autoimmune response to group A streptococcal
infection that causes damage to heart valves. The mitral valve is most commonly
affected, leading to mitral stenosis. The valve leaflets become thickened, fused,
and calcified, obstructing blood flow from the left atrium to the left ventricle.
Aortic valve involvement is also common but mitral stenosis is the classic finding.
Q6. A patient with mitral stenosis presents with dyspnea on exertion and atrial
fibrillation. The mechanism of dyspnea is:
A) Decreased left ventricular compliance
B) Increased left atrial pressure with pulmonary congestion
C) Right ventricular failure
D) Coronary artery disease
Answer: B) Increased left atrial pressure with pulmonary congestion
Rationale: Mitral stenosis obstructs blood flow from the left atrium to the left
ventricle. This increases left atrial pressure, which backs up into the pulmonary
veins and capillaries, causing pulmonary congestion and dyspnea. The increased
left atrial pressure also predisposes to atrial fibrillation due to atrial stretch and
fibrosis. Decreased LV compliance is seen in diastolic dysfunction. RV failure is a
late complication.
Q7. A patient with aortic stenosis presents with angina. The mechanism of angina
in this condition is:
A) Coronary artery atherosclerosis
B) Increased myocardial oxygen demand with supply-demand mismatch
C) Coronary vasospasm
D) Aortic dissection
3
, Answer: B) Increased myocardial oxygen demand with supply-demand mismatch
Rationale: Aortic stenosis causes significant left ventricular pressure overload,
leading to concentric hypertrophy. The hypertrophied myocardium has increased
oxygen demand. Additionally, the increased wall tension and compression of
subendocardial vessels reduce coronary perfusion. This creates a supply-demand
mismatch that causes angina, even with normal coronary arteries.
Q8. A patient with aortic regurgitation presents with a diastolic decrescendo
murmur. This murmur is best heard at:
A) Left upper sternal border
B) Right upper sternal border
C) Left lower sternal border
D) Apex
Answer: A) Left upper sternal border
Rationale: Aortic regurgitation causes a diastolic decrescendo murmur best heard
at the left upper sternal border with the patient sitting forward and exhaling. The
murmur is caused by blood flowing backward from the aorta into the left ventricle
during diastole. The right upper sternal border is where aortic stenosis is best
heard. The apex is where mitral valve murmurs are best heard.
Q9. A patient with pericarditis presents with pleuritic chest pain relieved by sitting
forward. The ECG finding most consistent with this diagnosis is:
A) ST elevation in a single lead
B) Diffuse concave ST elevation
C) Q waves in multiple leads
D) Peaked T waves
Answer: B) Diffuse concave ST elevation
Rationale: Pericarditis causes diffuse ST elevation (concave upward) in multiple
leads because the inflammatory process affects the entire epicardial surface. The
pain is typically pleuritic and relieved by sitting forward. ST elevation in a single
