, SECTION: HYPERTENSION & VASCULAR PATHOPHYSIOLOGY
Q1. A 58-year-old patient with a blood pressure of 168/102 mm Hg on two separate visits is diagnosed with primary hypertension.
The nurse explains that the dominant long-term pathophysiologic effect of sustained hypertension on the left ventricle is:
A. Acute myocarditis with rapid chamber dilation
B. Concentric hypertrophy caused by increased afterload and wall stress
C. Primary dilation of the aortic root without myocardial change
D. Selective atrophy of the interventricular septum
Correct Answer: B
Rationale: Chronic pressure overload from hypertension increases left-ventricular wall stress. The myocardium adapts by adding sarcomeres in
parallel, producing concentric hypertrophy that eventually impairs diastolic filling.
Q2. A patient with long-standing hypertension develops progressive renal insufficiency. The primary renal pathophysiologic
mechanism linking hypertension to chronic kidney disease is:
A. Isolated tubular necrosis without glomerular involvement
B. Primary hyperfiltration injury confined to the distal convoluted tubule
C. Hyaline arteriolosclerosis of afferent arterioles leading to glomerular ischemia and sclerosis
D. Acute interstitial nephritis driven solely by immune-complex deposition
Correct Answer: C
Rationale: Hypertension produces hyaline arteriolosclerosis that narrows afferent arterioles, reducing glomerular perfusion. Ischemia and
subsequent glomerular sclerosis progressively reduce GFR and produce hypertensive nephrosclerosis.
Q3. A middle-aged adult is found to have secondary hypertension caused by renal-artery stenosis. The nurse anticipates that the
dominant pathophysiologic driver of the elevated blood pressure is:
A. Activation of the renin–angiotensin–aldosterone axis by reduced renal perfusion
B. Primary overproduction of aldosterone independent of renin
C. Excessive secretion of atrial natriuretic peptide
D. Direct sympathetic denervation of the juxtaglomerular apparatus
Correct Answer: A
Rationale: Renal-artery stenosis lowers perfusion pressure distal to the stenosis, stimulating renin release. The resulting angiotensin II and
aldosterone raise systemic vascular resistance and sodium retention, producing secondary hypertension.
Q4. A patient with untreated severe hypertension develops acute chest pain and a widened mediastinum on chest radiograph. The
most likely acute aortic complication and its mechanism is:
A. Aortic stenosis from calcific degeneration of the valve leaflets
B. Isolated pericardial tamponade without aortic involvement
C. Coronary embolism from a left-atrial thrombus
D. Aortic dissection caused by intimal tear and propagation of a false lumen under high shear stress
Correct Answer: D
Rationale: Severe hypertension imposes extreme shear force on the aortic wall. An intimal tear allows blood to enter the media, creating a false
lumen that can extend and compromise branch vessels or rupture.
Q5. A nurse is teaching a patient newly diagnosed with essential hypertension about target-organ damage. Which statement
correctly identifies a classic hypertensive target-organ effect?
A. Accelerated atherosclerosis and left-ventricular hypertrophy that increase risk of stroke and heart failure
B. Selective destruction of pancreatic beta cells producing type 1 diabetes
C. Primary demyelination of peripheral nerves identical to Guillain-Barré syndrome
D. Isolated deficiency of intrinsic factor leading to pernicious anemia
Correct Answer: A
Rationale: Hypertension accelerates atherosclerosis and forces the left ventricle to hypertrophy against high afterload. These changes raise the
lifetime risk of coronary events, heart failure, stroke, and renal failure.
