Question 1
A patient is being evaluated for coronary artery disease (CAD) risk factors. The
nurse clinician understands that low-density lipoprotein (LDL) becomes a
component of an atherosclerotic plaque through which precise sequence of
steps?
A. Free LDL binds immediately to endothelial receptors and triggers an immediate
smooth muscle cell mutation.
B. LDL becomes oxidized when exposed to endothelial cells, smooth muscle
cells, and macrophages; it is then engulfed by macrophages to become a foam
cell that makes up the plaque.
C. High-density lipoprotein (HDL) breaks down the LDL molecules into bile salts
within the tunica media.
D. Intracellular sodium pumps pull the intact LDL molecule into the nuclear matrix
of myocardial cells.
CORRECT ANSWER: B
RATIONALE: According to the response to injury hypothesis of
atherosclerosis, plaque buildup begins with endothelial damage. When LDL
penetrates the damaged endothelium, it becomes oxidized through exposure to
endothelial cells, smooth muscle cells, and macrophages. Macrophages then engulf
this oxidized LDL, transforming into foam cells, which accumulate in the arterial
wall to form the core of the atherosclerotic plaque covered by a smooth muscle
cell cap. HDL opposes this process by performing reverse cholesterol transport,
returning excess cholesterol to the liver.
,Question 2
An advanced pathophysiology seminar discusses the relationship between
uncontrolled diabetes mellitus and accelerated cardiovascular risk. How does
chronic hyperglycemia directly alter lipoproteins to increase the risk for
coronary artery disease (CAD)?
A. High glucose concentrations cause the liver to stop producing apoproteins
permanently.
B. Glucose completely deactivates the alpha-1 and beta-1 adrenergic receptors in
the endocardium.
C. Lipoproteins are altered by glycation from high glucose levels, causing
greater integration into macrophages, which then accumulate in the arterial
wall and promote platelet aggregation.
D. Hyperglycemia forces a rapid shift to aerobic metabolism that lyses healthy
endothelial matrices.
CORRECT ANSWER: C
RATIONALE: In patients with diabetes mellitus, high circulating glucose
levels result in the glycation of lipoproteins. This chemical modification causes
them to be more readily integrated into and engulfed by macrophages. These
lipid-laden cells accumulate within the arterial wall, accelerating smooth muscle
proliferation, endothelial dysfunction, and platelet aggregation, which explains
why diabetes is a potent traditional risk factor for premature CAD.
Question 3
The nurse practitioner is reviewing lipid panel targets and particles associated with
cardiovascular disease. Which morphological trait of low-density lipoprotein
(LDL) is characteristically associated with an increased risk for coronary artery
disease (CAD)?
A. High numbers of large, puffy, and buoyant LDL particles
B. High numbers of small, dense LDL particles
C. High concentrations of glycated HDL steroid complexes
D. Total absence of any lipid core inside the circulating chylomicrons
CORRECT ANSWER: B
RATIONALE: Standard lipid panels measure total mass, but the particle size is
, a critical determinant of atherogenicity. An increased risk for CAD is specifically
associated with high numbers of small, dense LDL particles. These small,
dense particles more easily penetrate the endothelial lining, are more susceptible to
oxidation, and exhibit a higher affinity for the arterial wall matrix than large,
buoyant LDL particles.
Question 4
A patient's cardiac evaluation reveals a high concentration of high-sensitivity C-
reactive protein (hs-CRP). The nurse practitioner interprets this nontraditional
risk factor as which type of clinical indicator?
A. A direct genetic marker that code for the 9p21 chromosomal deletion sequence
B. A specific biliary enzyme that reflects the breakdown of cholesterol-containing
steroids
C. An acute-phase reactant made in the liver that serves as an indirect
measure of atherosclerotic plaque-related inflammation and progression
D. A protective antioxidant that prevents monocytes from binding to endothelial
cells
CORRECT ANSWER: C
RATIONALE: High-sensitivity C-reactive protein (hs-CRP) is an acute-
phase reactant synthesized by the liver in response to inflammatory cytokines. It
serves as a valuable indirect marker of atherosclerotic plaque-related
inflammation and disease progression. Elevated levels signify active, ongoing
vascular inflammation, which destabilizes the fibrous cap and increases the
likelihood of an acute plaque rupture and subsequent thrombosis.
Question 5
A pathology report describes an atherosclerotic lesion that contains an
accumulation of connective tissue, an increased number of smooth muscle cells, a
deeper lipid pool, and a fibrous cap that narrows the lumen. The nurse logs this
as which type of lesion?
A. Fatty streak
B. Fibrous plaque
