SECTION I: CELLULAR ADAPTATION, INJURY & GENETICS
(Questions 1–15)
Q1. A patient with long-standing hypertension develops left ventricular hypertrophy. This
is an example of which type of cellular adaptation?
• A. Atrophy
• B. Hyperplasia
• C. Metaplasia
• D. Dysplasia
CorreCt answer : B – Hypertrophy is an increase in cell size. In hypertension, the
left ventricle works against increased afterload, causing cardiac myocytes to enlarge as an
adaptive response.
Q2. The hallmark of apoptosis is characterized by:
• A. Cell swelling and lysis with associated inflammation
• B. Caseous necrosis with granuloma formation
• C. Cell shrinkage, nuclear fragmentation, and formation of apoptotic bodies without
inflammation
• D. Coagulative necrosis with preservation of tissue architecture
CorreCt answer : C – Apoptosis is programmed cell death characterized by cell
shrinkage, chromatin condensation, nuclear fragmentation, and formation of apoptotic bodies
that are phagocytosed without eliciting inflammation.
, Q3. A patient who smokes chronically develops replacement of normal ciliated columnar
epithelium with stratified squamous epithelium in the bronchi. This is an example of:
• A. Hypertrophy
• B. Hyperplasia
• C. Metaplasia
• D. Anaplasia
CorreCt answer : C – Metaplasia is the reversible replacement of one
differentiated cell type with another as an adaptive response to chronic irritation. Smoking
causes bronchial epithelium to change from ciliated columnar to stratified squamous.
Q4. A patient experiences prolonged immobilization following a hip fracture. Muscle
atrophy develops. Which molecular mechanism is most responsible?
• A. Increased ubiquitin-proteasome degradation of myofibrillar proteins
• B. Upregulation of insulin-like growth factor-1 (IGF-1) signaling
• C. Activation of the PI3K/Akt pathway
• D. Enhanced transcription of growth-promoting genes
CorreCt answer : A – Disuse atrophy involves increased ubiquitin-proteasome
degradation of myofibrillar proteins.
Q5. A 55-year-old patient with a BRCA1 gene mutation is at increased risk for which of the
following malignancies?
• A. Colon cancer
• B. Lung cancer
• C. Breast and ovarian cancer
• D. Prostate cancer
, CorreCt answer : C – BRCA1 mutations are associated with significantly increased
risk for breast and ovarian cancers due to impaired DNA repair mechanisms.
Q6. Which statement best describes the pathophysiology of cellular ischemia?
• A. Increased ATP production with enhanced oxidative phosphorylation
• B. Decreased ATP production leading to failure of the Na⁺/K⁺ pump, cellular swelling, and
acidosis
• C. Increased intracellular potassium and decreased intracellular sodium
• D. Activation of anaerobic glycolysis with increased glycogen stores
CorreCt answer : B – Ischemia reduces oxygen delivery, decreasing ATP
production. Failure of the Na⁺/K⁺ pump causes sodium and water to enter the cell, leading to
cellular swelling and acidosis.
Q7. A researcher is studying a tissue sample from a patient with chronic inflammation.
Which cellular process is most likely characterized by uncontrolled cell division, invasion, and
metastasis?
• A. Dysplasia
• B. Metaplasia
• C. Neoplasia
• D. Hyperplasia
CorreCt answer : C – Neoplasia is abnormal, uncontrolled cell growth that can
invade surrounding tissues and metastasize.
Q8. A newborn is diagnosed with cystic fibrosis. Which genetic inheritance pattern is
responsible?
• A. Autosomal dominant
• B. Autosomal recessive
