perfusion

rhythm. Which abnormality is primarily responsible for the irregular

renal dysfunction and left ventricular hypertrophy. Which vascular process
contributes to chronic target-organ injury?
A. Persistent elevation of arterial pressure causing endothelial and vascular
remodeling
B. Complete absence of sympathetic vascular stimulation
C. Permanent systemic vasodilation reducing tissue perfusion
D. Decreased arterial wall stress from reduced cardiac output
Answer: A
9. A patient with peripheral arterial disease reports calf pain after walking that
resolves with rest. Which pathophysiologic mechanism best explains
intermittent claudication?
A. Venous valve failure causing dependent venous pooling
B. Arterial obstruction limiting blood flow during increased muscle demand
C. Excess lymphatic drainage causing muscle ischemia
D. Increased capillary permeability causing acute compartment syndrome
Answer: B
10. A patient with chronic venous insufficiency develops lower-leg edema, skin
hyperpigmentation, and an ulcer near the medial malleolus. Which
mechanism is primarily responsible?
A. Chronic venous hypertension causing edema and tissue changes
B. Acute arterial embolization causing complete ischemia
C. Increased lymphatic absorption reducing interstitial fluid
D. Reduced capillary hydrostatic pressure causing tissue hypoxia
Answer: A
11. A patient develops sudden pleuritic chest pain, tachycardia, and dyspnea
after prolonged immobilization. Which pathophysiologic event is most
likely?
pg. 3
, A. Coronary artery spasm
B. Pulmonary embolization of a venous thrombus
C. Acute left ventricular rupture
D. Pericardial fluid accumulation
Answer: B
12. A patient with chronic heart failure develops worsening dyspnea when lying
flat and awakens at night gasping for air. Which mechanism best explains
these findings?
A. Pulmonary venous congestion caused by increased left-sided filling
pressures
B. Reduced pulmonary capillary pressure caused by hypovolemia
C. Increased systemic venous drainage into the lungs
D. Isolated bronchial smooth-muscle contraction
Answer: A
13. A patient with infective endocarditis develops a new cardiac murmur and
fever. Which pathophysiologic process is responsible for the murmur?
A. Destruction or interference with normal valvular function
B. Complete absence of ventricular contraction
C. Increased coronary perfusion during diastole
D. Decreased blood viscosity caused by infection
Answer: A
14. A patient develops acute aortic dissection with severe tearing chest pain
radiating to the back. Which process most directly causes the condition?
A. Rupture of a coronary plaque into the ventricular cavity
B. Separation of layers of the aortic wall after an intimal tear
C. Obstruction of the pulmonary artery by a thrombus
D. Inflammation limited to the pericardium
Answer: B
15. A patient with cardiac tamponade becomes hypotensive and develops
jugular venous distention. Which mechanism explains the hemodynamic
compromise?
pg. 4
