What term is used to identify when a cell is temporarily
deprived of blood supply?
a. Infarction
b. Ischemia
c. Necrosis
d. Inflammation - ANSWER- b. Ischemia
Rationale: 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?
,2|Page
a. Diabetes mellitus
b. Hypertension
c. Obesity
d. High alcohol consumption - ANSWER- b. Hypertension
Rationale: 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 - ANSWER- a. Diabetes mellitus
Rationale: 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 - ANSWER- c. High-density lipoproteins
(HDLs
Rationale: 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) - ANSWER- d. C-reactive protein
(CRP)
, 4|Page
Rationale: 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 - ANSWER- c. 20
Rationale: 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?
