,Section A - Cellular Injury AND Adaptation
Q1.
A novel chemotherapeutic agent inhibits the mitochondrial permeability transition pore.
Which of the following cellular processes is most directly impaired, and what is the
expected consequence?
A. Glycolysis; decreased ATP production B. Apoptosis; increased cell survival
C. Autophagy; accumulation of damaged D. Necrosis; increased inflammation
organelles
Correct: B - Apoptosis; increased cell survival
Rationale:The mitochondrial permeability transition pore is a key mediator of intrinsic
apoptosis. Inhibition prevents cytochrome c release, thus blocking apoptosis and promoting
cell survival. Glycolysis, autophagy, and necrosis are not directly dependent on this pore.
Q2.
A researcher identifies a mutation in a gene encoding a histone acetyltransferase. Which
of the following is the most likely direct effect on gene expression?
A. Increased chromatin condensation and B. Decreased chromatin condensation and
gene silencing gene activation
C. Impaired DNA methylation and gene D. Enhanced DNA repair and genomic
activation stability
Correct: A - Increased chromatin condensation and gene silencing
Rationale:Histone acetyltransferases add acetyl groups to histones, loosening chromatin and
promoting transcription. Loss of function leads to hypoacetylation, increased chromatin
condensation, and gene silencing. DNA methylation and repair are not direct targets.
Q3.
A patient with chronic heart failure develops peripheral edema. Which combination of
Starling forces is most likely responsible?
A. Increased capillary hydrostatic pressure B. Decreased capillary hydrostatic pressure
and decreased plasma oncotic pressure and increased interstitial oncotic pressure
C. Increased plasma oncotic pressure and D. Decreased capillary permeability and
decreased interstitial hydrostatic pressure increased lymphatic drainage
Correct: A - Increased capillary hydrostatic pressure and decreased plasma oncotic
pressure
Page 3
, Section A - Cellular Injury AND Adaptation
Rationale: Chronic heart failure raises venous pressure, increasing capillary hydrostatic
pressure, and may cause hepatic congestion reducing albumin synthesis, lowering plasma
oncotic pressure. Both favor fluid filtration into tissues. Other options oppose edema
formation.
Q4.
In a tissue sample, cells show loss of contact inhibition, anchorage-independent growth,
and increased expression of telomerase. Which additional finding would most strongly
indicate malignant progression?
A. Presence of apoptosis in the center of the B. Invasion through the basement
tumor membrane
C. Well-differentiated glandular structures D. Encapsulation by fibrous tissue
Correct: B - Invasion through the basement membrane
Rationale:Invasion through the basement membrane is a hallmark of malignancy,
distinguishing invasive carcinoma from benign tumors or in situ lesions. Apoptosis,
differentiation, and encapsulation are features of benign or less aggressive tumors.
Q5.
A patient's tumor is found to have a mutation in the gene encoding the p53 protein. Which
of the following functional consequences is most likely to contribute to tumor
progression?
A. Increased DNA repair and cell cycle B. Loss of apoptosis induction and genomic
arrest instability
C. Enhanced cell adhesion and contact D. Activation of tumor suppressor pathways
inhibition
Correct: B - Loss of apoptosis induction and genomic instability
Rationale:p53 is a tumor suppressor that induces apoptosis and cell cycle arrest in response
to DNA damage. Mutations lead to loss of these functions, allowing damaged cells to survive
and accumulate mutations, promoting genomic instability and tumor progression.
Q6.
A patient with sepsis develops disseminated intravascular coagulation. Which of the
following laboratory findings is most consistent with this condition?
A. Elevated platelet count and prolonged PT B. Decreased fibrinogen and elevated
D-dimer
