INSTRUCTIONS
Select the single best answer for each question.
Each question has one correct answer and three plausible distractors.
Questions focus on cellular pathophysiology, inflammation, immunity, genetics, and system-specific
disorders.
Assume standard adult physiology unless otherwise specified.
SECTION I: CELLULAR ADAPTATION & INJURY (Questions 1–8)
Q1 (NR507-01). A patient with chronic hypertension develops left ventricular hypertrophy. This change in
cardiac muscle represents which type of cellular adaptation?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: B
Rationale: Hypertrophy is an increase in cell size leading to increased organ size, occurring in response to
increased workload. Cardiomyocytes are permanent cells that cannot divide, so they adapt by enlarging
(hypertrophy). Hyperplasia (A) is increased cell number. Atrophy (C) is decreased cell size. Metaplasia (D) is
replacement of one cell type with another.

Q2 (NR507-02). A patient with chronic GERD develops Barrett's esophagus, in which the normal squamous
epithelium is replaced by columnar epithelium. This change is an example of:
A) Metaplasia
B) Dysplasia
C) Neoplasia
D) Hyperplasia
Answer: A
Rationale: Metaplasia is the reversible replacement of one differentiated cell type with another in response to
chronic irritation. Barrett's esophagus is a classic example. Dysplasia (B) is disordered cell growth. Neoplasia
(C) is new, uncontrolled growth. Hyperplasia (D) is increased cell number.

Q3 (NR507-03). A patient experiences a myocardial infarction due to prolonged lack of blood flow. The type
of cell death that occurs in this scenario is:
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis

D) Fat necrosis
Answer: A
Rationale: Coagulative necrosis is characteristic of cell death in solid organs (heart, kidney, liver) following
ischemia. Tissue architecture is preserved for several days. Liquefactive necrosis (B) occurs in the brain.
Caseous necrosis (C) occurs in tuberculosis. Fat necrosis (D) occurs in pancreatitis.

Q4 (NR507-04). A patient with chronic alcoholism develops liver cirrhosis with fibrosis and regenerating
nodules. The regenerating nodules represent which type of cellular adaptation?
A) Hyperplasia (regenerative)
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: A
Rationale: The liver has the ability to regenerate through hyperplasia (increased cell division) of hepatocytes.
In cirrhosis, chronic injury leads to fibrosis and nodular regeneration (hyperplastic nodules).

Q5 (NR507-05). A patient is exposed to ionizing radiation during cancer treatment. The radiation causes
DNA damage that leads to cell death. This type of cell death is characterized by:
A) Apoptosis (programmed cell death)
B) Necrosis (unprogrammed cell death)
C) Autophagy
D) Pyroptosis
Answer: A
Rationale: Ionizing radiation causes DNA damage that triggers apoptosis (programmed cell death) in sensitive
cells, particularly rapidly dividing cells (bone marrow, GI epithelium). Necrosis (B) is unprogrammed cell
death due to injury. Autophagy (C) is cellular recycling. Pyroptosis (D) is inflammatory cell death associated
with infection.

Q6 (NR507-06). A patient with chronic kidney disease develops secondary hyperparathyroidism. The
pathophysiology of secondary hyperparathyroidism in CKD involves:
A) Hyperphosphatemia and hypocalcemia stimulating PTH secretion
B) Hypophosphatemia and hypercalcemia suppressing PTH secretion
C) Increased vitamin D production
D) Decreased PTH receptor sensitivity
