SECTION 1: Cardiovascular Pathophysiology
Q1. A 68-year-old patient with a history of hypertension and coronary artery disease is admitted with progressive dyspnea, orthopnea, and
bilateral ankle edema. The nurse anticipates left-sided heart failure primarily because of which pathophysiologic mechanism?
A. Isolated right ventricular failure with systemic venous backup only
B. Acute rupture of a papillary muscle without prior ischemia
C. Primary sodium retention unrelated to cardiac function
D. Impaired left ventricular pumping that causes pulmonary venous congestion
Correct Answer: D
Rationale: Left-sided failure reduces forward flow and elevates left atrial and pulmonary venous pressures, producing pulmonary congestion and the classic
respiratory symptoms. Right-sided signs may appear later or secondary to left-sided disease.
Q2. A patient with long-standing hypertension develops left ventricular hypertrophy. The nurse understands that this adaptive change
initially helps maintain stroke volume but eventually contributes to heart failure because:
A. The thickened myocardium becomes stiffer and less able to fill adequately during diastole
B. Hypertrophy always decreases the number of myocytes
C. The heart permanently increases its resting metabolic demand without benefit
D. Hypertrophy converts contractile cells into fibroblasts exclusively
Correct Answer: A
Rationale: Pathologic hypertrophy increases wall thickness but reduces ventricular compliance, impairing diastolic filling and ultimately reducing cardiac output.
Q3. During an acute myocardial infarction, irreversible injury to myocardial cells is most closely associated with which duration of severe
ischemia?
A. Less than 5 minutes of reduced flow
B. Exactly 2 hours regardless of collateral circulation
C. Approximately 20–40 minutes of profound ischemia
D. Only after several days of intermittent ischemia
Correct Answer: C
Rationale: Myocardial cells can tolerate brief ischemia, but irreversible injury (necrosis) typically begins after roughly 20–40 minutes of severe oxygen
deprivation, depending on residual flow and metabolic demand.
Q4. A patient presents with crushing substernal chest pain radiating to the left arm, diaphoresis, and ST-segment elevation on ECG. The
underlying pathophysiology of this acute coronary syndrome is most often:
A. Rupture of an atherosclerotic plaque with superimposed thrombosis that occludes the coronary lumen
B. Gradual progressive narrowing without thrombosis
C. Coronary artery spasm without any atherosclerotic disease
D. Primary pericardial inflammation causing referred pain
Correct Answer: A
Rationale: Most ST-elevation myocardial infarctions result from acute plaque rupture that triggers platelet aggregation and thrombus formation, producing
sudden coronary occlusion.
Q5. A patient with atrial fibrillation is at increased risk for embolic stroke primarily because:
A. The ventricles always fibrillate simultaneously
B. Atrial stretch permanently destroys all clotting factors
C. Stasis of blood in the atria promotes thrombus formation that can embolize systemically
D. The condition lowers systemic blood pressure enough to cause watershed infarcts only
Correct Answer: C
Rationale: Loss of organized atrial contraction leads to blood stasis, particularly in the left atrial appendage, favoring thrombus formation and subsequent
embolization to the cerebral circulation.
