, Section 1: Cellular & Genetic Foundations – Adaptation, Injury, Genetics,
Neoplasia, Fluid/Electrolytes (30 questions)
Q1: Which type of cellular adaptation involves a decrease in cell size?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Atrophy [CORRECT]
Correct Answer: D
Rationale: Atrophy is a decrease in cell size. Hypertrophy increases size, hyperplasia increases number,
and metaplasia is a change in cell type.
Q2: Which type of cellular adaptation involves an increase in cell size?
A. Atrophy
B. Metaplasia
C. Hypertrophy [CORRECT]
D. Dysplasia
Correct Answer: C
Rationale: Hypertrophy is an increase in cell size. Atrophy decreases size, and the others differ.
Q3: Which type of cellular adaptation involves an increase in the number of cells?
A. Hyperplasia [CORRECT]
B. Hypertrophy
C. Atrophy
D. Metaplasia
Correct Answer: A
Rationale: Hyperplasia is an increase in cell number. The others are different adaptations.
Q4: Which type of cellular adaptation is a reversible change in which one adult cell type is replaced by another?
A. Dysplasia
B. Metaplasia [CORRECT]
C. Atrophy
D. Hyperplasia
Correct Answer: B
Rationale: Metaplasia is the replacement of one adult cell type by another. Dysplasia is disordered growth,
and the others differ.
Q5: Which of the following is a disorderly, often pre-neoplastic cell growth?
A. Metaplasia
B. Dysplasia [CORRECT]
C. Hyperplasia
D. Atrophy
Correct Answer: B
Rationale: Dysplasia is disordered growth, often pre-neoplastic. The others are different adaptations.

, Q6: Which type of necrosis is most typical of ischemic cell death (e.g., in a myocardial infarction)?
A. Liquefactive necrosis
B. Coagulative necrosis [CORRECT]
C. Caseous necrosis
D. Fat necrosis
Correct Answer: B
Rationale: Coagulative necrosis is typical of ischemia (e.g., MI). Liquefactive occurs in the brain, caseous in
TB, and fat necrosis in fatty tissue.
Q7: Which type of necrosis is characteristic of a tuberculous infection?
A. Coagulative necrosis
B. Caseous necrosis [CORRECT]
C. Liquefactive necrosis
D. Fat necrosis
Correct Answer: B
Rationale: Caseous necrosis is characteristic of TB. The others are different types of necrosis.
Q8: Which type of necrosis is most typical of the brain?
A. Coagulative necrosis
B. Caseous necrosis
C. Fibrinoid necrosis
D. Liquefactive necrosis [CORRECT]
Correct Answer: D
Rationale: The brain undergoes liquefactive necrosis. Coagulative is typical of other organs. The others
differ.
Q9: Which of the following is programmed cell death that is energy-dependent and does not typically trigger
inflammation?
A. Necrosis
B. Gangrene
C. Caseation
D. Apoptosis [CORRECT]
Correct Answer: D
Rationale: Apoptosis is programmed, energy-dependent cell death without inflammation. Necrosis triggers
inflammation. The others differ.
Q10: Which of the following is TRUE about necrosis?
A. It is programmed cell death
B. It is unregulated cell death that triggers an inflammatory response [CORRECT]
C. It is always benign
D. It does not cause inflammation
Correct Answer: B
Rationale: Necrosis is unregulated cell death with inflammation. Apoptosis is programmed. The others are
incorrect.
WGU D027 Advanced Pathopharmacological Foundations - 2026/2027 Edition Page 3
, Q11: Which of the following is the hallmark of acute inflammation?
A. Neutrophil infiltration and edema [CORRECT]
B. Lymphocyte infiltration and fibrosis
C. Granuloma formation
D. Scar tissue
Correct Answer: A
Rationale: Acute inflammation features neutrophils and edema. Chronic inflammation features lymphocytes,
granulomas, and fibrosis.
Q12: Which of the following is a mediator of the immune response?
A. Cytokines, interleukins, and chemokines [CORRECT]
B. Only glucose
C. Only electrolytes
D. Only oxygen
Correct Answer: A
Rationale: Cytokines, interleukins, and chemokines are immune mediators. The others are not.
Q13: Which of the following is TRUE about the role of genetics in disease?
A. Genetics has no role
B. All diseases are purely genetic
C. Genetic variations can influence disease risk and drug metabolism (pharmacogenomics) [CORRECT]
D. Genetics only affects appearance
Correct Answer: C
Rationale: Genetic variations influence disease risk and drug metabolism. The others are incorrect.
Q14: Which of the following is an example of pharmacogenomics?
A. Giving the same dose to everyone
B. Ignoring genetics
C. Using CYP2D6 genotype to guide drug selection/dosing [CORRECT]
D. Using age alone for dosing
Correct Answer: C
Rationale: Pharmacogenomics uses genetic variants (e.g., CYP2D6) to guide therapy. The others are
incorrect.
Q15: Which enzyme is commonly involved in pharmacogenomic drug metabolism?
A. CYP2D6 (and other CYP enzymes) [CORRECT]
B. Amylase
C. Trypsin
D. Pepsin
Correct Answer: A
Rationale: CYP enzymes, especially CYP2D6, are key in drug metabolism. The others are digestive
enzymes.
