Question 1 point
The release of cytoplasmic enzymes from necrotic cells may be useful diagnostically.
true
fals
e
Question 2 point
Bilirubin is:
lipid soluble when conjugated
water soluble when conjugated
conjugated in the kidney for excretion in the urine
Question
point
3
Agents such as radiation, mutagenic drugs and viruses can lead to acquired DNA abnormalities.
Damage to cells such as blood cell precursors in the bone marrow is the result of:
failed synthesis of structural proteins
failure of growth regulating proteins
interference with mitosis
Question 4 point
Free radicals can impair cell membrane function by causing:
lesions in DNA
lipid peroxidation
protein cross-linking
Question 5 point
Anemia will lead to impaired energy production by the cell because there is:
insufficient
oxygen
low glucose levels
enzyme inhibition
Question 6 point
The primary change in hemolytic jaundice is:
inadequate bilirubin excretion
increased production of bilirubin
serum accumulation of conjugated
bilirubin
Question 7 point
Triglyceride accumulation in the cytoplasm of parenchymal cells (such as the liver) is termed:
cytoplasmic
vacuolation
, hyperglycemia
fatty degeneration
Question 8 point
Hypoxia, leading to impaired energy production by the cell, may be caused by:
anemia
low blood glucose levels
inhibition of respiratory enzymes
Question 9 point
Death of cells in a living organism is termed:
gangren
e
necrosis
ischemia
Question 10 point
Starvation can lead to the development of fatty liver.
true
fals
e
Question
point
11
Cloudy swelling is the result of:
intracellular accumulation of fluid and
electrolytes
decreased intracellular pH
triglyceride accumulation
Question 12 point
The most definitive microscopic evidence of cell necrosis is:
homogenous, more deeply staining
cytoplasm
cytoplasmic vacuolation
nuclear pyknosis and karrhyorhexis
Question 13 point
Chronic over-consumption of alcohol can lead to fatty liver due to:
decreased oxidation of triglycerides
increased activity of hepatic enzyme systems, leading to increased conversion
of fatty acids to triglycerides
decreased mobilization of adipose tissue due to increased alcoholic caloric
consumption
