What term is used to identify when a cell is temporarily
deprived of blood supply?
a. Infarction
b. Ischemia
c. Necrosis
d. Inflammation Correct Answer b. Ischemia
Coronary artery disease (CAD) can diminish the
myocardial blood supply until deprivation impairs
myocardial metabolism enough to cause ischemia, a
local state in which the cells are temporarily deprived
of blood supply.
The risk of developing coronary artery disease is
increased up to threefold by which factor?
a. Diabetes mellitus
b. Hypertension
c. Obesity
,d. High alcohol consumption Correct Answer b.
Hypertension
Hypertension is the only factor responsible for a
twofold-to-threefold increased risk of atherosclerotic
cardiovascular disease.
Which risk factor is associated with coronary artery
disease (CAD) because of its relationship with the
alteration of hepatic lipoprotein?
a. Diabetes mellitus
b. Hypertension
c. Obesity
d. High alcohol consumption Correct Answer a. Diabetes
mellitus
Of the available options, only diabetes mellitus is
associated with CAD because of the resulting
alteration of hepatic lipoprotein synthesis; it increases
triglyceride levels and is involved in low-density
lipoprotein oxidation.
Which elevated value may be protective of the
development of atherosclerosis?
a. Very low-density lipoproteins (VLDLs)
b. Low-density lipoproteins (LDLs)
c. High-density lipoproteins (HDLs
d. Triglycerides Correct Answer c. High-density
lipoproteins (HDLs
,Low levels of HDL cholesterol are also a strong
indicator of coronary risk, whereas high levels of
HDLs may be more protective for the development of
atherosclerosis than low levels of LDLs.
Which laboratory test is an indirect measure of
atherosclerotic plaque?
a. Homocysteine
b. Low-density lipoprotein (LDL)
c. Erythrocyte sedimentation rate (ESR)
d. C-reactive protein (CRP) Correct Answer d. C-reactive
protein (CRP)
Highly sensitive CRP (hs-CRP) is an acute phase
reactant or protein mostly synthesized in the liver and,
of the available options, is an indirect measure of
atherosclerotic plaque-related inflammation.
Cardiac cells can withstand ischemic conditions and still
return to a viable state for how many minutes?
a. 10
b. 15
c. 20
d. 25 Correct Answer c. 20
Cardiac cells remain viable for approximately 20
minutes under ischemic conditions. If blood flow is
restored, then aerobic metabolism resumes,
, contractility is restored, and cellular repair begins. If
the coronary artery occlusion persists beyond 20
minutes, then myocardial infarction (MI) occurs.
Which form of angina occurs most often during sleep as a
result of vasospasms of one or more coronary arteries?
a. Unstable
b. Stable
c. Silent
d. Prinzmetal Correct Answer d. Prinzmetal
Of the options available, only Prinzmetal angina (also
called variant angina) is chest pain attributable to
transient ischemia of the myocardium that occurs
unpredictably and almost exclusively at rest.
When is the scar tissue that is formed after a myocardial
infarction (MI) most vulnerable to injury?
a. Between 5 and 9 days
b. Between 10 and 14 days
c. Between 15 and 20 days
d. Between 20 and 30 days Correct Answer b. Between 10
and 14 days
During the recovery period (10 to 14 days after
infarction), individuals feel more capable of increasing
activities and thus may stress the newly formed scar
tissue.
