Which statement regarding arteriosclerosis is TRUE? Arteriosclerosis is:
a. an acute process of heart muscle degeneration
b. thickening and hardening of
... [Show More] the vessel wall
c. plaque caused by accumlation of hormones
d. fatty streaks and foam cell that are identical.-ANSWERS-thickening and hardening of
the vessel wall
Arteriosclerosis is a chronic degeneration of blood vessel walls. A plaque is caused by
collagen over a fatty streak that is composed of a large number of lipid-laden foam cells
that deposit on the vessel wall.
A patient experiences a rapidly progressive hypertension with a diastolic pressure of
146 mm Hg. Which is the correct term for this condition?
a. primary hypertension
b. secondary hypertension
c. complicated hypertension
d. malignant hypertension-ANSWERS-malignant hypertension
Hypertensive crisis (or malignant hypertension) is rapidly progressive hypertension in
which diastolic pressure is usually greater than 140 mm Hg. It can occur in those with
primary hypertension, but the reason why some people develop this complication and
others do not is unknown. As hypertension becomes more severe and chronic, tissue
damage can occur in the blood vessels and tissues leading to target organ damage in
the heart, kidney, brain, and eyes. Primary hypertension is the term used to identify
hypertension that has no known cause. Secondary hypertension is the term used to
identify hypertension caused by altered hemodynamics. There is no tertiary
hypertension.
A condition in which blood has pooled, producing distended and palpable vessels, is
referred to as a:
a. thrombus
b. venous stasis ulcers
c. varicose veins
d. deep vein thrombosis-ANSWERS-varicose veins.
Varicose veins are distended and palpable vessels. Thrombus is a blood clot that
remains attached to a vessel wall. Venous stasis ulcers are caused by cell death and
necrosis secondary to trauma or pressure-induced oxygen deficiency. Deep vein
thrombosis is a thrombus formation occurring mainly in the lower extremities.
