QUESTION; Ethanol (alcohol) causes cell injury by which of the following
mechanisms?
a. Cellular dehydration
b. Intracellular sodium loss
c. Lipid accumulation in hepatocytes
d. Hypoxic injury - ANSWER-c. Lipid accumulation in hepatocytes
Rationale: Ethanol metabolism causes lipid accumulation in hepatocytes that
decreases liver function and may result in liver cirrhosis.
QUESTION; In compensatory hyperplasia, growth factors stimulate cell division in
response to:
a. decreased hormonal stimulation.
b. ischemia.
c. tissue loss.
d. puberty. - ANSWER-c. tissue loss.
,Question; A direct result of anaerobic metabolism during hypoxic cell injury is:
a. increased ATP
b. metabolic acidosis
c. tissue ischemia
d. all of the above. - ANSWER-b. metabolic acidosis
Rationale: When oxygen is not available, cells switch to anaerobic metabolism,
which yields an acid called lactate, or lactic acid.
QUESTION; Accumulation of which of the following molecules results in
irreversible cell injury?
a. Calcium
b. Melanin
c. Lipids
d. Water - ANSWER-a. Calcium
Rationale: The accumulation of calcium causes irreversible mitochondrial injury.
QUESTION; Adaptive cellular mechanisms function to:
a. speed up cellular death.
b. prevent cellular aging.
c. treat disease.
,d. protect cells from injury. - ANSWER-d.protect cells from injury.
QUESTION; An individual with damage to the spinal cord may experience atrophy
of which of the following organs?
a. Skeletal muscles
b. Skin
c. Liver
d. Brain - ANSWER-a. Skeletal muscles
Rationale: Lack of nerve stimulation to skeletal muscles results in muscle atrophy.
QUESTION; Chronic infection of the cervix by the human papillomavirus results in
cervical:
a. hormonal hyperplasia.
b. atrophy.
c. dysplasia.
d. metaplasia. - ANSWER-c. dysplasia.
Rationale: (Chronic infection or inflammation is a common cause of cervical
dysplasia.)
QUESTION; Ethanol (alcohol) causes cell injury by which of the following
mechanisms?
a. Cellular dehydration
b. Intracellular sodium loss
, c. Lipid accumulation in hepatocytes
d. Hypoxic injury - ANSWER-c. Lipid accumulation in hepatocytes
Rationale: Ethanol metabolism causes lipid accumulation in hepatocytes that
decreases liver function and may result in liver cirrhosis.
QUESTION; In compensatory hyperplasia, growth factors stimulate cell division in
response to:
a. decreased hormonal stimulation.
b. ischemia.
c. tissue loss.
d. puberty. - ANSWER-c. tissue loss.
Rationale: In response to tissue loss, surrounding cells are stimulated to replace
the lost tissue.
QUESTION; In response to an increased workload, such as that caused by high
blood pressure (hypertension), myocardial cells in the left ventricle will adapt
through the process of:
a. hyperplasia.
b. hypertrophy.
c. atrophy.
d. dysplasia. - ANSWER-b. hypertrophy.
