SECTION 1: CARDIOVASCULAR PATHOPHYSIOLOGY (Questions 1-20)
Q1: Which pathological lesion represents the earliest recognizable stage of atherosclerosis and can already be
found in the aortas of children and young adults?
A. Fibrous plaque with calcification of the intima
B. Fatty streak composed of lipid-laden foam cells [CORRECT]
C. Complicated lesion with intraplaque hemorrhage
D. Atheromatous ulceration with overlying thrombus
Correct Answer: B
Rationale: The fatty streak, composed of lipid-loaded macrophages (foam cells) within the intima, is the earliest lesion
of atherosclerosis and may appear as early as childhood, consistent with the NSG 530 progression model (endothelial
injury, fatty streak, fibrous plaque, complicated lesion). Fibrous plaques (A), complicated lesions with hemorrhage (C),
and ulcerated plaques with thrombus (D) are later stages that evolve from the fatty streak over decades of inflammation
and lipid accumulation.

Q2: A 58-year-old man presents with 40 minutes of crushing substernal chest pain radiating to the left arm and
jaw, diaphoresis, and nausea. ECG shows ST-segment elevation in leads II, III, and aVF. Occlusion of which
coronary artery is the most likely cause of this presentation?
A. Left anterior descending (LAD) artery
B. Left circumflex artery
C. Right coronary artery [CORRECT]
D. Left main coronary artery
Correct Answer: C
Rationale: Leads II, III, and aVF face the inferior wall of the left ventricle, which is supplied by the right coronary
artery in approximately 85 percent of people with right-dominant circulation. The LAD (A) supplies the anterior wall
and septum with changes in V1-V4, the left circumflex (B) supplies the lateral wall with changes in I, aVL, V5-V6, and
left main occlusion (D) produces massive anterolateral injury, usually with hemodynamic collapse.
Q3: Which sequence best describes the pathophysiologic role of endothelial dysfunction in the initiation of
atherosclerosis, as emphasized in advanced pathophysiology?
A. Reduced nitric oxide bioavailability increases vascular adhesion molecule expression, promoting
monocyte adherence and transmigration into the intima [CORRECT]
B. Increased nitric oxide release causes vasodilation and recruits platelets to the vessel wall
C. Endothelial cells directly transform into smooth muscle cells and calcify the tunica media
D. Loss of endothelium exposes the adventitia, triggering immediate fibrinolysis
Correct Answer: A
Rationale: Dysfunctional endothelial cells produce less nitric oxide (losing vasodilator and anti-inflammatory
protection) and express more VCAM-1 and ICAM-1, which tether circulating monocytes that migrate into the intima,
engulf oxidized LDL, and become foam cells, the substrate of the atheromatous plaque. Increased nitric oxide (B) is
protective rather than harmful, endothelial cells do not transdifferentiate into calcifying smooth muscle (C), and the
adventitia is not the surface exposed by endothelial injury (D).
Q4: A 72-year-old woman with longstanding hypertension and coronary disease is hospitalized for worsening
dyspnea. She has orthopnea, paroxysmal nocturnal dyspnea, and bilateral basilar crackles. Which mechanism
best explains her pulmonary crackles?
A. Right ventricular failure causing systemic venous congestion and ascites
B. Hepatic cirrhosis causing transudative pleural effusions
C. Pulmonary embolism increasing alveolar dead space
D. Left ventricular failure raising left atrial and pulmonary venous pressure, forcing fluid into the
pulmonary interstitium and alveoli [CORRECT]
Correct Answer: D
Rationale: Left-sided failure causes blood to back up upstream of the left ventricle: left atrial pressure rises and
transmits to pulmonary veins and capillaries, and when hydrostatic pressure exceeds plasma oncotic pressure,
transudation produces interstitial and alveolar edema that is audible as crackles. Right-sided failure (A) causes
peripheral edema, hepatomegaly, and ascites rather than pulmonary edema, and options B and C do not reflect the
hydrostatic mechanism of cardiogenic pulmonary congestion.

Q5: A 61-year-old woman admitted with chest pain has serial cardiac markers drawn. Which laboratory
finding is the most specific indicator of myocardial cell injury in acute myocardial infarction?
A. Elevation of creatine kinase-MB (CK-MB) 24 hours after symptom onset
B. Elevated cardiac troponin I detectable within 3-4 hours and persisting up to 10 days [CORRECT]
C. Elevated serum myoglobin persisting for one week
D. Elevated lactate dehydrogenase (LDH) fraction 1
Correct Answer: B
Rationale: Cardiac troponins I and T are regulatory proteins found almost exclusively in cardiac muscle, making them
the most specific biomarkers of myocardial injury; they rise within 3-4 hours, peak at about 24-48 hours, and remain
elevated for 7-10 days. CK-MB (A) is less specific because skeletal muscle injury also elevates it and it normalizes
within 2-3 days, myoglobin (C) is the earliest but least specific marker, and LDH isoenzymes (D) are obsolete for
diagnosing myocardial infarction.
Q6: A 68-year-old hypertensive woman reports exertional dyspnea and fatigue. Echocardiography shows an
ejection fraction of 65 percent, left ventricular wall thickening, and no regional wall motion abnormalities.
BNP is mildly elevated. Which diagnosis is most consistent with these findings?
A. HFrEF (systolic heart failure) from dilated cardiomyopathy
B. Cor pulmonale from chronic lung disease
C. HFpEF (diastolic heart failure) from decreased ventricular compliance [CORRECT]
D. Constrictive pericarditis from prior tuberculosis
Correct Answer: C
Rationale: A preserved ejection fraction of 50 percent or more with exertional dyspnea and elevated BNP defines
HFpEF, in which chronic hypertension produces left ventricular hypertrophy and stiffness that impair active relaxation
and passive filling, raising filling pressures despite normal systolic emptying. HFrEF (A) requires a reduced ejection
fraction below 40 percent, cor pulmonale (B) is right-sided failure from lung disease, and constrictive pericarditis (D)
is distinguished by pericardial thickening with equalization of diastolic pressures, not ventricular wall thickening.
Q7: A 34-year-old woman has resistant hypertension despite three antihypertensive medications. Auscultation
reveals an abdominal bruit, and imaging shows a string-of-beads appearance of the renal arteries. Which
mechanism explains her hypertension?
A. Renal artery stenosis reducing perfusion pressure and activating the renin-angiotensin-aldosterone
system [CORRECT]
B. Primary hyperaldosteronism from bilateral adrenal hyperplasia
C. Excess catecholamine secretion from a pheochromocytoma
D. Increased circulating volume from advanced chronic kidney disease
Correct Answer: A
Rationale: Fibromuscular dysplasia produces segmental stenosis of the renal artery with a string of beads on
angiography; the reduced afferent perfusion pressure is sensed by the juxtaglomerular apparatus, which releases renin,
generating angiotensin II vasoconstriction and aldosterone-mediated sodium retention, the classic renovascular
secondary hypertension. Hyperaldosteronism (B) presents with hypokalemia without a renal bruit, pheochromocytoma
(C) produces episodic headache, sweating, and palpitations, and volume overload of chronic kidney disease (D) does
not create localized bruits.

Q8: Which statement about primary (essential) hypertension is most accurate according to the NSG 530
pathophysiology framework?
A. It has a single, identifiable cause in over 80 percent of affected adults
B. It accounts for only about 20 percent of hypertension cases
C. It always results from excess aldosterone secretion
D. It constitutes roughly 90-95 percent of hypertension and reflects interacting genetic, environmental,
and neurohumoral factors without a single identifiable cause [CORRECT]
Correct Answer: D
Rationale: Primary hypertension represents 90-95 percent of all hypertension and is a multifactorial, heterogeneous
disorder involving sympathetic overactivity, abnormalities of the renin-angiotensin-aldosterone system, renal sodium
handling, vascular remodeling, and genetic predisposition, with no single curable cause. Secondary hypertension, the
remaining 5-10 percent, is the category with identifiable causes such as primary aldosteronism, renovascular disease,
and pheochromocytoma, making options A, B, and C incorrect.
Q9: Three days after an extensive anterior myocardial infarction, a 66-year-old man becomes hypotensive (BP
82/50 mmHg), tachycardic, and diaphoretic with cool, mottled extremities and new bibasilar crackles.
Hemodynamic monitoring shows cardiac index 1.7 L/min/m2 and pulmonary capillary wedge pressure 24
mmHg. Which type of shock is most consistent with these findings?
A. Hypovolemic shock from depressed preload
B. Cardiogenic shock from pump failure with high filling pressures [CORRECT]
C. Distributive shock from peripheral vasodilation
D. Obstructive shock from increased pulmonary vascular resistance
Correct Answer: B
Rationale: The combination of low cardiac output plus elevated wedge pressure after myocardial infarction indicates
pump failure: the damaged left ventricle cannot eject adequate output despite excessive preload, producing cold,
vasoconstricted extremities and pulmonary edema. Hypovolemic shock (A) would show low filling pressures,
distributive shock (C) produces warm, flushed extremities with high cardiac output, and obstructive shock (D) requires
a mechanical cause such as tamponade, tension pneumothorax, or massive pulmonary embolism.
