Guaranteed – A+ Graded
SECTION 1: Cellular Pathophysiology & Genetics (10 questions)
Q1: Which of the following is a hallmark of malignant transformation?
A. Increased apoptosis
B. Loss of contact inhibition [CORRECT]
C. Decreased cellular proliferation
D. Increased cellular adhesion
Correct Answer: B
Rationale: Correct because malignant cells lose contact inhibition, allowing
uncontrolled proliferation independent of normal regulatory signals and tissue
boundaries.
Q2: A patient presents with fatigue, pallor, and shortness of breath on exertion.
Laboratory findings reveal microcytic, hypochromic anemia with low serum ferritin.
What is the most likely diagnosis?
A. Iron deficiency anemia [CORRECT]
B. Vitamin B12 deficiency anemia
C. Folic acid deficiency anemia
D. Anemia of chronic disease
Correct Answer: A
Rationale: Correct because microcytic, hypochromic anemia with low ferritin is the
classic presentation of iron deficiency anemia, the most common nutritional
deficiency worldwide.
Q3: Which type of hypersensitivity reaction is involved in anaphylaxis?
A. Type I [CORRECT]
B. Type II
C. Type III
,D. Type IV
Correct Answer: A
Rationale: Correct because anaphylaxis is a Type I IgE-mediated hypersensitivity
reaction involving mast cell degranulation and massive release of histamine and
other mediators.
Q4: A patient with chronic alcohol use develops hepatic steatosis. Which cellular
adaptation best describes this initial change?
A. Hypertrophy
B. Hyperplasia
C. Fatty change (steatosis) [CORRECT]
D. Metaplasia
Correct Answer: C
Rationale: Correct because hepatic steatosis represents fatty change, an intracellular
accumulation of triglycerides within hepatocytes due to altered lipid metabolism
from alcohol.
Q5: Which mechanism is primarily responsible for cellular swelling during reversible
cell injury?
A. Increased protein synthesis
B. Decreased ATP-dependent sodium-potassium pump function [CORRECT]
C. Excessive mitochondrial DNA replication
D. Lysosomal membrane stabilization
Correct Answer: B
Rationale: Correct because ATP depletion causes failure of the Na+/K+-ATPase
pump, leading to intracellular accumulation of sodium and water, producing cellular
hydropic swelling.
Q6: A patient with sickle cell disease experiences a vaso-occlusive crisis. What
triggers this?
A. Increased oxygen saturation
B. Increased hydration
C. Dehydration, infection, or hypoxia [CORRECT]
D. Increased exercise alone
Correct Answer: C
Rationale: Correct because dehydration, infection, hypoxia, and acidosis promote
hemoglobin S polymerization and red blood cell sickling, causing vascular occlusion
and tissue ischemia.
, Q7: Apoptosis differs from necrosis primarily because apoptosis:
A. Triggers an inflammatory response
B. Is always pathological in nature
C. Involves programmed cell death without inflammation [CORRECT]
D. Results from acute traumatic injury
Correct Answer: C
Rationale: Correct because apoptosis is energy-dependent programmed cell death
characterized by cell shrinkage, chromatin condensation, and formation of apoptotic
bodies that are phagocytosed without triggering an inflammatory response.
Q8: Which process describes the replacement of one differentiated cell type with
another?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia [CORRECT]
D. Dysplasia
Correct Answer: C
Rationale: Correct because metaplasia is a reversible adaptive change where one
mature differentiated cell type is replaced by another mature differentiated cell type,
often in response to chronic irritation.
Q9: Free radical injury to cell membranes is primarily mediated through:
A. Protein denaturation
B. Lipid peroxidation [CORRECT]
C. DNA methylation
D. Glycogen depletion
Correct Answer: B
Rationale: Correct because free radicals attack polyunsaturated fatty acids in
membrane phospholipids, initiating lipid peroxidation that destroys membrane
integrity and produces more reactive oxygen species.
Q10: Which enzyme activation is most responsible for cellular degradation in
calcium-mediated cell injury?
A. Amylase
B. Lipase
C. Phospholipase and proteases [CORRECT]
D. Hyaluronidase
Correct Answer: C
