Hematologic Disorders
Question 1: A 62-year-old male with a 15-year history of poorly controlled
hypertension presents with progressive dyspnea and echocardiographic
evidence of left ventricular wall thickening. Which cellular adaptation best
explains this finding?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
CORRECT ANSWER: B. Hypertrophy
Rationale: Cardiac muscle cells are permanent cells that cannot divide after birth.
In response to chronic pressure overload from hypertension, individual
myocardial cells increase in size to meet the increased functional demand,
resulting in left ventricular hypertrophy. Hyperplasia cannot occur in cardiac
muscle because these cells lack mitotic capacity.
Question 2: A 34-year-old female with no significant medical history undergoes
routine cervical cytology. The report describes replacement of normal
endocervical columnar epithelium with stratified squamous epithelium at the
transformation zone. Which cellular adaptation does this represent?
A. Metaplasia
B. Dysplasia
C. Hyperplasia
D. Anaplasia
CORRECT ANSWER: A. Metaplasia
Rationale: Metaplasia is the reversible replacement of one mature, differentiated
cell type with another mature cell type that is better suited to withstand
environmental stress. The transformation zone of the cervix commonly undergoes
,squamous metaplasia, where columnar epithelium is replaced by stratified
squamous epithelium.
Question 3: A 55-year-old male with a 30-pack-year smoking history undergoes
bronchoscopy. Biopsy reveals disorganized epithelial growth with variation in
nuclear size and shape, hyperchromatic nuclei, and loss of normal polarity.
Which term best describes this finding?
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Atrophy
CORRECT ANSWER: C. Dysplasia
Rationale: Dysplasia is characterized by disordered cellular growth with atypical
changes in size, shape, and organization of cells. It is considered a premalignant
condition and frequently precedes carcinoma in situ and invasive malignancy.
Unlike metaplasia, dysplasia involves abnormal cellular features rather than
simple cell type substitution.
Question 4: A 70-year-old female sustains a femoral neck fracture and is placed
in skeletal traction for eight weeks. Upon removal of traction, marked reduction
in thigh muscle mass is observed. Which mechanism best explains this change?
A. Loss of endocrine stimulation
B. Decreased workload
C. Diminished blood supply
D. Loss of innervation
CORRECT ANSWER: B. Decreased workload
Rationale: Disuse atrophy results from decreased functional demand on a tissue.
When muscles are immobilized and not actively used, protein synthesis decreases
while protein degradation increases, leading to a reduction in cell size. This is a
reversible adaptation if activity is resumed.
Question 5: A 48-year-old female with chronic kidney disease undergoes renal
biopsy. The pathology report describes an increase in the number of cells in the
,proximal tubule epithelium without evidence of atypical features. Which
cellular adaptation is present?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
CORRECT ANSWER: B. Hyperplasia
Rationale: Hyperplasia is an increase in the number of cells in an organ or tissue.
In chronic kidney disease, compensatory hyperplasia of remaining nephrons may
occur as the kidney attempts to maintain function. This is a physiologic adaptation
that can occur in tissues capable of mitotic division.
Question 6: A 52-year-old male with a chronic history of gastroesophageal reflux
disease undergoes endoscopy. Biopsy of the distal esophagus reveals
replacement of normal stratified squamous epithelium with columnar
epithelium containing goblet cells. This finding is most consistent with which
process?
A. Dysplasia
B. Anaplasia
C. Metaplasia
D. Neoplasia
CORRECT ANSWER: C. Metaplasia
Rationale: Barrett esophagus represents intestinal metaplasia, in which chronic
acid exposure causes the normal stratified squamous epithelium of the esophagus
to be replaced by columnar epithelium with goblet cells. This is a metaplastic
adaptation that increases the risk of subsequent dysplasia and adenocarcinoma.
Question 7: A 28-year-old female experiences breast enlargement during her
first pregnancy. This change is primarily attributed to which cellular adaptation?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
, CORRECT ANSWER: B. Hyperplasia
Rationale: Breast enlargement during pregnancy results from estrogen- and
progesterone-stimulated proliferation of glandular epithelial cells and ductal
structures. This is a physiologic hyperplasia, an increase in cell number, which is
distinct from hypertrophy, which involves an increase in cell size only.
Question 8: A 45-year-old male with a history of recurrent urinary tract
infections develops a contracted, fibrotic bladder with reduced capacity. Which
type of atrophy is most likely contributing to this finding?
A. Disuse atrophy
B. Ischemic atrophy
C. Compression atrophy
D. Endocrine atrophy
CORRECT ANSWER: B. Ischemic atrophy
Rationale: Chronic inflammation and fibrosis can compromise the blood supply to
the detrusor muscle, leading to ischemic atrophy. Reduced blood flow causes
inadequate oxygen and nutrient delivery, resulting in shrinkage of cells and loss of
functional tissue.
Question 9: A 60-year-old female with a long-standing history of
hyperparathyroidism undergoes renal ultrasound, which reveals multiple cysts
and diffuse parenchymal loss. Which type of cellular injury is most likely
responsible for these changes?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Fat necrosis
D. Caseous necrosis
CORRECT ANSWER: A. Coagulative necrosis
Rationale: Chronic hyperparathyroidism can lead to nephrocalcinosis and
ischemic injury to renal tissue. Coagulative necrosis occurs in ischemic injury to
solid organs such as the kidney, where tissue architecture is preserved initially,
though cellular details are lost.
