reasoning and mechanism-based understanding across all major body systems and
pathophysiological processes.
Content Areas Covered:
• Cellular Adaptation, Injury, and Death (Questions 1–30)
• Genetics and Genetic Disorders (Questions 31–50)
• Immunity, Inflammation, and Infection (Questions 51–90)
• Fluid, Electrolyte, and Acid-Base Imbalances (Questions 91–120)
• Endocrine Disorders (Questions 121–160)
• Cardiovascular Disorders (Questions 161–190)
• Respiratory Disorders (Questions 191–220)
• Neurological Disorders (Questions 221–260)
• Renal and Urological Disorders (Questions 261–280)
• Reproductive Disorders (Questions 281–300)
,SECTION 1: CELLULAR ADAPTATION, INJURY, AND DEATH
1. A patient with chronic hypertension develops thickening of the left
ventricular wall. Which cellular adaptation does this represent?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size, not number. Cardiac muscle
cells cannot divide, so they enlarge in response to increased workload
(hypertension). Hyperplasia (A) involves increased cell number and occurs in
tissues capable of mitosis. Metaplasia (C) is replacement of one cell type with
another. Dysplasia (D) is disordered growth, often preneoplastic.
2. Which type of necrosis is most commonly associated with ischemic injury to
the heart and kidneys?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Correct Answer: C
Rationale: Coagulative necrosis occurs when ischemia causes protein
denaturation, preserving the basic cell structure for days. It is characteristic of
infarcts in the heart, kidney, and spleen. Liquefactive necrosis (A) occurs in the
brain. Caseous necrosis (B) is seen in tuberculosis. Fat necrosis (D) occurs in
pancreatitis.
,3. A biopsy of the esophagus reveals replacement of normal squamous
epithelium with columnar epithelium in a patient with chronic GERD. This is
an example of:
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Anaplasia
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one mature cell type with
another that is better able to survive the stressful environment. In Barrett's
esophagus, chronic acid exposure causes squamous to columnar change.
Hyperplasia (A) increases cell number. Hypertrophy (B) increases cell size.
Anaplasia (D) is lack of differentiation, seen in malignancy.
4. Which process is characterized by programmed cell death that does not
trigger inflammation?
A. Necrosis
B. Apoptosis
C. Gangrene
D. Autolysis
Correct Answer: B
Rationale: Apoptosis is genetically programmed cell death that eliminates
unwanted cells without inflammation. The cell shrinks and fragments into
apoptotic bodies that are phagocytosed. Necrosis (A) triggers inflammation due to
membrane rupture. Gangrene (C) is massive tissue death. Autolysis (D) is self-
digestion by enzymes.
5. During ischemia, which electrolyte imbalance occurs intracellularly that
contributes to cell injury?
, A. Increased potassium and decreased sodium
B. Increased sodium and calcium, decreased potassium
C. Increased magnesium and decreased calcium
D. Increased chloride and decreased phosphate
Correct Answer: B
Rationale: Ischemia depletes ATP, causing the Na⁺/K⁺-ATPase pump to fail.
Sodium and calcium accumulate intracellularly, while potassium leaks out.
Calcium overload activates enzymes that damage cell membranes. This sequence is
central to irreversible cell injury.
6. A patient with a vitamin B12 deficiency develops megaloblastic anemia.
Which cellular process is impaired?
A. Glycolysis
B. DNA synthesis
C. Protein folding
D. Oxidative phosphorylation
Correct Answer: B
Rationale: Vitamin B12 is essential for DNA synthesis. Deficiency impairs
nuclear maturation while cytoplasmic development continues, producing large,
immature red blood cells (megaloblasts). Glycolysis (A) is glucose breakdown.
Protein folding (C) occurs in the ER. Oxidative phosphorylation (D) occurs in
mitochondria.
7. Which of the following best describes dysplasia?
A. Reversible replacement of one mature cell with another
B. Increase in cell number in response to stress
C. Disordered, atypical proliferation of cells
D. Programmed cell death
Correct Answer: C
