SECTION 1: CELLULAR ADAPTATION AND INJURY (QUESTIONS 1-20)
1. QUESTION: Which of the following best describes hypertrophy as a cellular
adaptation?
A) Decrease in cell size due to reduced protein synthesis
B) Increase in cell number through rapid cell division
C) Increase in cell size due to increased protein synthesis and accumulation of
cytoplasmic components
D) Structural change in cell shape without change in function
E) Programmed cell death in response to injury
CORRECT ANSWER: C) Increase in cell size due to increased protein synthesis
and accumulation of cytoplasmic components
,RATIONALE: Hypertrophy is an adaptive response where individual cells increase in
size, not in number. This occurs through increased protein synthesis and
accumulation of cytoplasmic organelles. A classic example is cardiac hypertrophy in
response to chronic hypertension. The enlarged cells maintain normal function,
making this a true adaptation to physiological demand. Hyperplasia (option B)
involves increased cell number, not size. Atrophy (option A) is the opposite
response. Options D and E describe other cellular changes but not hypertrophy
specifically.
2. QUESTION: A 58-year-old male presents with significant left ventricular
hypertrophy secondary to 20 years of uncontrolled hypertension. What is the
primary mechanism driving this cardiac adaptation?
A) Increased cardiac output causing eccentric hypertrophy
B) Increased afterload causing concentric hypertrophy with thickened left
ventricular wall
C) Decreased stroke volume requiring compensatory cell enlargement
D) Reduced coronary perfusion leading to ischemic adaptation
E) Increased preload from fluid retention
CORRECT ANSWER: B) Increased afterload causing concentric hypertrophy
with thickened left ventricular wall
RATIONALE: Hypertension increases afterload (resistance against which the heart
must pump), forcing cardiac myocytes to hypertrophy concentrically. This creates a
thick-walled ventricle with a normal or reduced chamber size. This adaptation
initially maintains cardiac output against increased resistance but eventually leads
to diastolic dysfunction. Eccentric hypertrophy (option A) occurs with volume
overload. The other options misrepresent the hemodynamic mechanisms driving
hypertensive heart disease.
,3. QUESTION: Which cellular adaptation is characterized by a decrease in cell
size and is commonly seen in the quadriceps muscle following immobilization
of the leg?
A) Hyperplasia
B) Atrophy
C) Metaplasia
D) Dysplasia
E) Anaplasia
CORRECT ANSWER: B) Atrophy
RATIONALE: Atrophy is a reversible adaptive decrease in cell size that occurs when
cells are subjected to decreased demand or reduced blood supply. Muscle atrophy
from immobilization results from loss of innervation signals and decreased use.
This is a protective adaptation that reduces the metabolic demands of unused
tissue. Hyperplasia involves increased cell number (option A). Metaplasia, dysplasia,
and anaplasia (options C, D, E) represent maladaptive changes or pathological
processes rather than normal adaptive responses.
4. QUESTION: A 45-year-old female smoker with chronic obstructive
pulmonary disease (COPD) demonstrates replacement of ciliated columnar
epithelium with stratified squamous epithelium in her respiratory tract. This
cellular change represents which type of adaptation?
A) Hypertrophy of epithelial cells
B) Metaplasia of respiratory epithelium
C) Aplasia of ciliated cells
D) Dysplasia with increased stratification
E) Hyperplasia of basal cells only
CORRECT ANSWER: B) Metaplasia of respiratory epithelium
, RATIONALE: Metaplasia is a reversible change where one differentiated cell type is
replaced by another differentiated cell type. Chronic smoking and irritation cause
replacement of the protective ciliated columnar epithelium with more resistant
stratified squamous epithelium. While this adaptation protects against irritation, it
compromises mucociliary clearance, increasing infection risk. This is a maladaptive
response despite being a true adaptation. The other options describe different
pathological processes but not the epithelial transformation seen in COPD.
5. QUESTION: Which of the following scenarios best exemplifies physiologic
hyperplasia?
A) Increased size of the heart in athletes
B) Breast tissue enlargement during pregnancy
C) Liver enlargement from glycogen accumulation
D) Muscle hypertrophy from resistance training
E) Neuronal enlargement in learning
CORRECT ANSWER: B) Breast tissue enlargement during pregnancy
RATIONALE: Physiologic hyperplasia is an increase in cell number in response to
physiologic demand, completely reversible when the stimulus ends. Breast tissue
enlargement during pregnancy represents true hyperplasia driven by hormonal
stimulation (estrogen and progesterone), preparing tissue for lactation. Tissue
returns to normal after lactation ends. Option A represents hypertrophy, not
hyperplasia. Option C shows accumulation, not cell proliferation. Options D and E
represent adaptive hypertrophy rather than hyperplasia.
6. QUESTION: A pathology slide shows a tissue sample with cells exhibiting
loss of normal organization, increased nuclear-to-cytoplasmic ratio, and
irregular nuclear membranes. The cells remain within the tissue boundary.
What does this most likely represent?
A) Anaplasia
