Total Questions: 185
Time Allowed: 3 Hours (simulated)
Instructions: Choose the single best answer for each question. Correct answers are
marked in bold. Rationales are provided for each answer.
Section 1: Cellular Adaptation & Injury (Questions 1–25)
1. Which of the following is an example of physiologic hyperplasia?
a) Hyperplasia of breast tissue during menopause
b) Endometrial hyperplasia due to estrogen therapy
c) Uterine enlargement during pregnancy
d) Prostatic hyperplasia in elderly men
Rationale: Pregnancy-induced uterine enlargement is due to hormone-driven
increased cell division, which is normal and physiologic. Options a, b, and d are
pathologic.
2. A patient with chronic anemia develops an enlarged heart. This is most
likely due to:
a) Hyperplasia
b) Dysplasia
c) Hypertrophy
d) Metaplasia
Rationale: Chronic anemia increases cardiac workload, leading to myocyte
enlargement (hypertrophy) without increased cell number.
, 3. Squamous metaplasia in the bronchi of a smoker is:
a) Irreversible
b) Reversible
c) Malignant
d) Always precancerous
Rationale: Metaplasia is reversible if the irritant (smoking) is removed.
4. Which cellular change is considered a direct precursor to malignancy?
a) Atrophy
b) Hypertrophy
c) Metaplasia
d) Dysplasia
Rationale: Dysplasia involves disordered growth and is often premalignant (e.g.,
cervical dysplasia).
5. Ischemic injury causes cell damage primarily by:
a) Direct DNA fragmentation
b) ATP depletion
c) Lysosomal rupture
d) Oxidative phosphorylation excess
Rationale: Ischemia reduces oxygen → oxidative phosphorylation stops → ATP
depletion → cellular swelling and death.
6. Which finding is characteristic of reversible cell injury?
a) Karyorrhexis
b) Cellular swelling
c) Pyknosis
d) Membrane blebbing with rupture
Rationale: Cellular swelling (hydropic change) is reversible; nuclear changes and
membrane rupture indicate irreversible injury.

downloadable version; below are representative selections to show depth.)
19. Apoptosis differs from necrosis in that apoptosis:
a) Causes inflammation
b) Is energy-dependent
