QUESTIONS | TESTED AND TRIED ANSWERS |
LATEST UPDATE 2024/2025 100% (GRADE A+)
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.
Ans>> b. metabolic acidosis
Rationale: When oxygen is not available, cells switch to anaerobic metabolism, which yields an
acid called lactate, or lactic acid.
Accumulation of which of the following molecules results in irreversible cell injury?
a. Calcium
b. Melanin
c. Lipids
1
,d. Water
Ans>> a. Calcium
Rationale: The accumulation of calcium causes irreversible mitochondrial injury.
Adaptive cellular mechanisms function to:
a. speed up cellular death.
b. prevent cellular aging.
c. treat disease.
d. protect cells from injury.
Ans>> d.protect cells from injury.
An individual with damage to the spinal cord may experience atrophy of which of the following
organs?
a. Skeletal muscles
b. Skin
2
,c. Liver
d. Brain
Ans>> a. Skeletal muscles
Rationale: Lack of nerve stimulation to skeletal muscles results in muscle atrophy.
Chronic infection of the cervix by the human papillomavirus results in cervical:
a. hormonal hyperplasia.
b. atrophy.
c. dysplasia.
d. metaplasia.
Ans>> c. dysplasia.
Rationale: (Chronic infection or inflammation is a common cause of cervical dysplasia.)
Ethanol (alcohol) causes cell injury by which of the following mechanisms?
a. Cellular dehydration
b. Intracellular sodium loss
3
, c. Lipid accumulation in hepatocytes
d. Hypoxic injury
Ans>> c. Lipid accumulation in hepatocytes
Rationale: Ethanol metabolism causes lipid accumulation in hepatocytes that decreases liver
function and may result in liver cirrhosis.
In compensatory hyperplasia, growth factors stimulate cell division in response to:
a. decreased hormonal stimulation.
b. ischemia.
c. tissue loss.
d. puberty.
Ans>> c. tissue loss.
Rationale: In response to tissue loss, surrounding cells are stimulated to replace the lost tissue.
