questions and correct detailed answers
[VERIFIED ANSWERS] [GRADE A+]
The risk of developing coronary artery disease is increased up to threefold by which
factor?
a. Diabetes mellitus
c. Obesity
b. Hypertension
d. High alcohol consumption - correct answer ANS: B
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
c. Obesity
b. Hypertension
d. High alcohol consumption - correct answer ANS: A
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.
Nicotine increases atherosclerosis by the release of which neurotransmitter?
a. Histamine
c. Angiotensin II
b. Nitric oxide
d. Epinephrine - correct answer ANS: D

questions and correct detailed answers
[VERIFIED ANSWERS] [GRADE A+]
Nicotine stimulates the release of catecholamines (e.g., epinephrine, norepinephrine),
which increases the heart rate and causes peripheral vascular constriction. As a
result, blood pressure increases, as do both cardiac workload and oxygen demand.
None of the other options are associated with this mechanism.
Which substance is manufactured by the liver and primarily contains cholesterol and
protein?
a. Very low-density lipoproteins (VLDLs)
b. Low-density lipoproteins (LDLs)
c. High-density lipoproteins (HDLs)
d. Triglycerides - correct answer ANS: B
A series of chemical reactions in the liver results in the production of several
lipoproteins that vary in density and function. These include VLDLs, primarily
triglycerides and protein; LDLs, mostly cholesterol and protein; and HDLs, mainly
phospholipids and protein. LDLs are the only lipoproteins that are manufactured by the
liver and primarily contain cholesterol and protein.
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 ANS: C
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. Neither VLDLs nor elevated triglycerides are associated with
a protective mechanism.
