Q1: A 62-year-old male with a 40-pack-year smoking history and hyperlipidemia asks the nurse
practitioner how fatty deposits develop in his coronary arteries. Which sequence best describes the
initial pathophysiologic mechanism of atherosclerosis?
A. Venous stasis and fibrin deposition forming mural thrombi within the coronary lumen
B. Smooth muscle apoptosis within the intima leading to thinning of the fibrous cap and vessel dilation
C. Calcification of the tunica media with subsequent medial artery wall stiffening and aneurysm
formation
D. Endothelial injury allowing LDL oxidation, macrophage uptake, and transformation into
lipid-laden foam cells [CORRECT]
Correct Answer: D
Rationale: Atherosclerosis begins with endothelial injury or dysfunction, which increases permeability and permits
LDL entry into the intima where it is oxidized. Circulating monocytes migrate in, become macrophages, engulf oxidized
LDL, and transform into foam cells that form the earliest fatty streak, consistent with the response-to-injury model
taught in NSG 530. Option A describes venous thrombosis rather than arterial plaque initiation. Option C describes
Monckeberg medial calcific sclerosis, a distinct entity, and Option B describes plaque destabilization, a late event rather
than the initiating mechanism.
Q2: A 58-year-old woman reports substernal chest pressure that occurs after climbing two flights of
stairs, lasts about 5 minutes, and is reliably relieved by rest. Cardiac catheterization shows a stable 75%
stenosis of the left anterior descending artery. Which mechanism best explains her chest pain?
A. Complete thrombotic occlusion of a coronary vessel with transmural myocardial necrosis
B. Spontaneous coronary artery dissection reducing flow in a structurally normal vessel
C. Demand ischemia distal to a fixed atherosclerotic plaque when myocardial oxygen
requirements exceed supply [CORRECT]
D. Coronary vasospasm of a non-diseased segment occurring characteristically at rest
Correct Answer: C
Rationale: Stable angina results from a fixed, stable atherosclerotic plaque that limits coronary flow reserve; symptoms
appear when exertion increases myocardial oxygen demand beyond the restricted supply and resolve when demand falls
with rest. This supply-demand imbalance concept is a core NSG 530 coronary pathophysiology principle. Option A
describes STEMI physiology, Option B describes an uncommon traumatic or peripartum event, and Option B describes
variant (Prinzmetal) angina, which occurs at rest and is vasospastic rather than plaque-driven.

Q3: A 66-year-old man presents to the emergency department with 45 minutes of crushing substernal
chest pain radiating to the jaw, diaphoresis, and nausea. His ECG shows 3-mm ST-segment elevation in
leads II, III, and aVF. Which pathophysiologic event is the most likely underlying cause of this
presentation?
A. Progressive gradual narrowing of a coronary artery by a stable lipid plaque over many years
B. Diffuse microvascular spasm associated with cocaine use and hypercoagulability
C. Severe aortic stenosis producing a fixed reduction in global coronary perfusion pressure
D. Sudden rupture or erosion of an unstable atherosclerotic plaque with acute thrombotic
occlusion of the vessel [CORRECT]
Correct Answer: D
Rationale: ST-segment elevation myocardial infarction is caused by abrupt rupture or erosion of an unstable plaque,
exposing the subendothelial matrix, triggering platelet adhesion and aggregation, and producing complete thrombotic
occlusion with transmural ischemia. The inferior ST elevation in II, III, and aVF localizes the event to the right coronary
artery territory. NSG 530 emphasizes that plaque stability, not stenosis severity alone, determines acute coronary
syndrome presentation. Option A produces stable angina, Option C causes chronic demand ischemia, and Option D is an
atypical cause not supported by this presentation.
Q4: Four hours after the onset of acute chest pain, a patient's laboratory panel is drawn. Which cardiac
biomarker pattern is most specific for confirming acute myocardial infarction at this time point?
A. Elevated troponin I with normal myoglobin, because troponin rises within 3 to 4 hours and is
the most cardiac-specific marker [CORRECT]
B. Isolated elevation of LDH with a flipped LDH1/LDH2 ratio, because LDH is the first marker to rise
C. Elevated C-reactive protein and sedimentation rate, because inflammation peaks before myocyte
injury markers
D. Normal CK-MB with elevated BNP, because BNP rises earlier than CK-MB in coronary occlusion
Correct Answer: A
Rationale: Cardiac troponin I begins to rise within 3 to 4 hours of myocyte necrosis, peaks at 18 to 24 hours, and
remains elevated for 7 to 10 days, and it is the most specific marker of myocardial injury in current NSG 530 and
AACN-aligned practice. Myoglobin rises earlier but is nonspecific. Option B is incorrect because LDH is an outdated,
late-rising marker with poor specificity. Option C describes nonspecific inflammatory markers, and Option D is
incorrect because BNP reflects ventricular wall stress rather than acute myocyte necrosis.
Q5: On hospital day 4 following an acute anterior myocardial infarction, a 71-year-old patient suddenly
develops pulmonary edema and a new loud holosystolic murmur heard loudest at the apex radiating to
the axilla. Which mechanical complication has most likely occurred?
A. Ventricular free wall rupture with cardiac tamponade
B. Interventricular septal rupture producing a left-to-right shunt
C. Papillary muscle rupture causing acute mitral regurgitation [CORRECT]
D. Ventricular aneurysm formation with mural thrombus embolization
Correct Answer: C
Rationale: Papillary muscle rupture typically occurs 3 to 7 days post-infarction, when coagulative necrosis weakens the
muscle supporting the mitral valve leaflets, producing acute severe mitral regurgitation with a holosystolic apical
murmur radiating to the axilla and flash pulmonary edema. This timeline and murmur pattern is a classic NSG 530
mechanical-complication teaching point. Option A would present with tamponade physiology and electromechanical
dissociation rather than a murmur, Option B produces a harsh holosystolic murmur at the left sternal border with a
step-up in right-sided oxygen saturation, and Option D is a late complication presenting with heart failure or embolic
events.

Q6: Which statement best characterizes the pathogenesis of primary (essential) hypertension?
A. A single identifiable renal artery lesion produces excessive renin release in more than 90% of cases
B. Chronic excess aldosterone secretion from a solitary adrenal adenoma causing potassium wasting
C. Autoimmune destruction of adrenal medullary chromaffin cells leading to episodic catecholamine
surges
D. An interacting combination of sympathetic overactivity, renal sodium retention, and vascular
remodeling with no single identifiable cause [CORRECT]
Correct Answer: D
Rationale: Primary hypertension accounts for 90 to 95% of cases and arises from multifactorial interactions among
sympathetic nervous system overactivity, renal sodium retention, increased vascular tone, and genetic and lifestyle
factors, without one identifiable cause. This multifactorial neurohormonal model is central to NSG 530 cardiovascular
content. Option A describes secondary renovascular hypertension, Option B describes primary aldosteronism, and
Option C describes a pheochromocytoma-like mechanism, all of which are secondary causes accounting for only a small
minority of cases.
Q7: A 31-year-old woman with newly diagnosed hypertension resistant to three drug classes is found to
have an abdominal bruit, recurrent flash pulmonary edema, and elevated plasma renin activity.
Angiography reveals a string-of-beads appearance of the renal artery. Which mechanism explains her
hypertension?
A. Renal artery stenosis activating the renin-angiotensin-aldosterone system, causing
vasoconstriction and sodium retention [CORRECT]
B. Adrenal medullary hyperplasia with intermittent catecholamine secretion and beta-cell stimulation
C. Mineralocorticoid receptor activation causing sodium retention and potassium wasting with
suppressed renin
D. Glomerular capillary hypertension producing proteinuria and progressive nephron loss
Correct Answer: A
Rationale: The string-of-beads lesion is characteristic of fibromuscular dysplasia, which stenoses the renal artery,
lowers perfusion pressure in the affected kidney, and activates renin release, angiotensin II-mediated vasoconstriction,
and aldosterone-driven sodium retention. NSG 530 identifies renovascular disease as a classic reversible cause of
secondary hypertension in young women. Option B describes pheochromocytoma physiology, Option C describes
primary aldosteronism in which renin is suppressed, and Option D describes hypertensive nephrosclerosis, which is a
consequence rather than the cause of her severe early-onset hypertension.
Q8: A 54-year-old man with dilated cardiomyopathy presents with orthopnea, bibasilar crackles, an S3
gallop, and an ejection fraction of 25%. Which pathophysiologic process is the primary defect in his
condition?
A. Impaired ventricular relaxation and increased chamber stiffness with preserved contractility
B. Loss of myocyte contractile function causing reduced ejection fraction and ventricular
dilation with volume overload [CORRECT]
C. Diastolic collapse of the right ventricle produced by pericardial fluid under pressure
D. Dynamic left ventricular outflow obstruction with hypercontractile basal septum
Correct Answer: B
Rationale: HFrEF is defined by impaired myocardial contractility, reduced ejection fraction, ventricular dilation, and
compensatory volume retention that produces congestion, an S3 gallop, and orthopnea. Neurohormonal activation of the
sympathetic nervous system and RAAS drives the maladaptive remodeling central to NSG 530 heart failure content.
Option A defines HFpEF, Option C describes cardiac tamponade, and Option D describes hypertrophic obstructive
cardiomyopathy, none of which match a dilated ventricle with EF 25%.
