Q1 Question 1 of 100
A 55-year-old male with a 30-pack-year smoking history presents with chronic cough and weight loss. A
lung biopsy reveals cells with large, irregular nuclei and loss of normal tissue architecture. This cellular
change is best described as which type of cellular adaptation?
A. Dysplasia
B. Hyperplasia
C. Metaplasia
D. Hypertrophy
Correct Answer: A
Rationale:
Dysplasia refers to abnormal, disorganized cell growth with loss of normal architecture and irregular nuclear
morphology, often a precursor to malignancy. Hyperplasia is an increase in cell number, metaplasia is replacement of
one cell type by another, and hypertrophy is an increase in cell size.
Q2 Question 2 of 100
A 48-year-old female with severe anemia has elevated lactate levels. Her cells are undergoing anaerobic
metabolism due to tissue hypoxia. The shift from aerobic to anaerobic metabolism primarily affects which
organelle?
A. Ribosome
B. Golgi apparatus
C. Mitochondrion
D. Lysosome
Correct Answer: C
Rationale:
The mitochondrion is the primary site of aerobic metabolism (oxidative phosphorylation), and hypoxia impairs
mitochondrial function, forcing cells to rely on anaerobic glycolysis in the cytoplasm. Ribosomes are for protein
synthesis, Golgi for processing, and lysosomes for degradation.
Q3 Question 3 of 100
A 62-year-old male who suffered a myocardial infarction has elevated cardiac troponin levels. The
myocardial cell death observed in this patient is classified as which type of necrosis?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct Answer: C
Rationale:
Coagulative necrosis is the characteristic pattern of cell death in ischemic tissue such as myocardial infarction, where
cell architecture is preserved but proteins are denatured. Liquefactive necrosis occurs in the brain, caseous necrosis in
tuberculosis, and fat necrosis in pancreatic tissue.

,Q4 Question 4 of 100
A 35-year-old male presents with recurrent infections and is found to have a genetic defect in the NADPH
oxidase enzyme system in his phagocytes. This defect leads to impaired production of which substance
critical for microbial killing?
A. Hydrogen peroxide and reactive oxygen species
B. Nitric oxide
C. Lysozyme
D. Complement component C3b
Correct Answer: A
Rationale:
NADPH oxidase deficiency (chronic granulomatous disease) impairs the respiratory burst, preventing production of
hydrogen peroxide and other reactive oxygen species needed for intracellular microbial killing. Nitric oxide is produced
by a different enzyme, lysozyme degrades cell walls, and complement functions independently of NADPH oxidase.
Q5 Question 5 of 100
A 40-year-old female presents with a history of heavy menstrual bleeding and is found to have iron
deficiency anemia. At the cellular level, iron deficiency primarily impairs which process?
A. Hemoglobin synthesis in developing erythrocytes
B. DNA replication in the nucleus
C. Cell membrane transport of sodium
D. Lysosomal degradation of cellular debris
Correct Answer: A
Rationale:
Iron is an essential component of the heme group in hemoglobin, and its deficiency directly impairs hemoglobin
synthesis in developing erythrocytes, producing microcytic hypochromic anemia. DNA replication is impaired by folate
or B12 deficiency, sodium transport depends on Na/K-ATPase, and lysosomal function is not primarily iron-dependent.
Q6 Question 6 of 100
A 50-year-old patient with chronic alcohol use disorder develops hepatic steatosis. The accumulation of
triglycerides within hepatocytes is an example of which type of cellular injury?
A. Intracellular accumulation (fatty change)
B. Atrophy
C. Calcification
D. Apoptosis
Correct Answer: A
Rationale:
Hepatic steatosis (fatty change) is an intracellular accumulation of triglycerides within hepatocytes due to impaired lipid
metabolism from alcohol toxicity. Atrophy is cell shrinkage, calcification is deposition of calcium salts, and apoptosis is
programmed cell death, none of which describe triglyceride accumulation.

, Q7 Question 7 of 100
A 3-year-old child with cystic fibrosis has recurrent pulmonary infections and pancreatic insufficiency. The
underlying genetic defect involves which type of protein?
A. A chloride channel (CFTR) with impaired function
B. A sodium channel with gain-of-function mutation
C. A potassium channel with loss of regulation
D. A calcium channel with increased permeability
Correct Answer: A
Rationale:
Cystic fibrosis is caused by mutations in the CFTR gene encoding a chloride channel, resulting in defective chloride
transport, thick mucus secretions, and recurrent infections. It is not a sodium, potassium, or calcium channel disorder,
and it involves loss-of-function rather than gain-of-function.
Q8 Question 8 of 100
A 45-year-old male with extensive burn injuries develops massive tissue edema. The primary mechanism
driving this edema formation is which of the following?
A. Increased hydrostatic pressure within capillaries
B. Decreased oncotic pressure from protein loss
C. Increased capillary permeability allowing protein-rich fluid leakage
D. Lymphatic obstruction preventing fluid return
Correct Answer: C
Rationale:
Burn injuries cause massive increase in capillary permeability, allowing protein-rich fluid to escape into the interstitial
space, creating edema. While hydrostatic pressure and oncotic pressure changes contribute, the primary mechanism
in burns is increased permeability, and lymphatic obstruction is not the main driver.
Q9 Question 9 of 100
A 70-year-old female with osteoporosis sustains a hip fracture. Examination of the bone tissue would
most likely reveal which finding?
A. Decreased bone mass and deterioration of bone microarchitecture
B. Increased osteoblast activity and excessive bone formation
C. Increased osteoclast inhibition and thickened trabeculae
D. Normal bone architecture with increased mineralization
Correct Answer: A
Rationale:
Osteoporosis is characterized by decreased bone mass and deterioration of the microarchitecture of bone tissue,
leading to increased fracture risk. Osteoblast activity is insufficient relative to resorption, osteoclast activity is not
inhibited (it is relatively increased), and mineralization may be normal but bone quantity is reduced.
