,NU 621 Final Exam Advanced Pathophysiology Questions And
Answers 2026/2027 Herzing University
Q1. A patient with chronic systemic hypertension develops left
ventricular hypertrophy. Which mechanism best explains this
adaptation?
A) Chronic volume depletion
B) Reduced venous return
C) Decreased myocardial workload
D) Persistent pressure overload increases ventricular wall stress
Correct Answer: D) Persistent pressure overload increases ventricular wall
stress
Rationale: Chronic hypertension increases afterload, causing myocardial
fibers to hypertrophy to generate greater pressure during ventricular
ejection.
Q2. Which hemodynamic change is most characteristic of systolic
heart failure?
A) Increased ventricular compliance
B) Increased ejection fraction
C) Improved myocardial contractility
D) Reduced ventricular contractility and ejection fraction
Correct Answer: D) Reduced ventricular contractility and ejection fraction
Rationale: Systolic dysfunction results from impaired contraction, which
lowers stroke volume and ejection fraction.
Q3. Which mechanism contributes most directly to pulmonary
edema in left-sided heart failure?
A) Increased pulmonary capillary hydrostatic pressure
B) Reduced pulmonary venous pressure
C) Increased plasma oncotic pressure
D) Decreased intravascular volume
Correct Answer: A) Increased pulmonary capillary hydrostatic pressure
Rationale: Backward transmission of elevated left-sided pressure forces
fluid from pulmonary capillaries into the interstitium and alveoli.
Q4. A patient develops peripheral edema and jugular venous
distention from heart failure. Which chamber is primarily failing?
A) Left atrium
B) Left ventricle
C) Right ventricle
D) Aorta
, Correct Answer: C) Right ventricle
Rationale: Right ventricular failure increases systemic venous pressure and
produces dependent edema and jugular venous distention.
Q5. Which pathophysiologic event initiates most acute coronary
syndromes?
A) Complete destruction of the myocardium
B) Chronic venous congestion
C) Rupture or erosion of an atherosclerotic plaque with thrombus formation
D) Decreased platelet activity
Correct Answer: C) Rupture or erosion of an atherosclerotic plaque with
thrombus formation
Rationale: Plaque disruption exposes thrombogenic material, triggering
platelet aggregation and acute coronary thrombosis.
Q6. Which lipoprotein is most strongly associated with progression
of atherosclerosis when elevated?
A) HDL
B) LDL
C) Albumin
D) Immunoglobulin G
Correct Answer: B) LDL
Rationale: LDL can enter the arterial intima, undergo oxidation, and
contribute to foam-cell and plaque formation.
Q7. A patient has exertional chest discomfort that predictably
resolves with rest. Which mechanism is most likely?
A) Complete coronary occlusion
B) Pericardial inflammation
C) Fixed coronary narrowing that limits blood flow during increased demand
D) Acute aortic rupture
Correct Answer: C) Fixed coronary narrowing that limits blood flow during
increased demand
Rationale: Stable angina occurs when myocardial oxygen demand exceeds
supply through a chronically narrowed coronary artery.
Q8. Which factor is included in Virchow's triad for venous
thrombosis?
A) Hypercoagulability
B) Bronchospasm
C) Myocardial hypertrophy
D) Increased lymphatic drainage
