Question 1
A 70-year-old patient who has been bedridden for three weeks due to a hip fracture exhibits a
significant decrease in the size of their gastrocnemius muscle. Which cellular adaptation has
occurred?
A) Hyperplasia
B) Atrophy
C) Dysplasia
D) Hypertrophy
E) Metaplasia
Correct Answer: B) Atrophy
Rationale: Atrophy is the decrease in cellular size. Pathologic atrophy can occur due to
disuse (as seen in this bedridden patient), decreased workload, pressure, or loss of nerve
stimulation. While the cells decrease in size, they remain functional but at a diminished
capacity.
Question 2
During early childhood, the thymus gland naturally decreases in size. This is an example of:
A) Pathologic atrophy
B) Physiologic atrophy
C) Pathologic hyperplasia
D) Physiologic hypertrophy
E) Metaplasia
Correct Answer: B) Physiologic atrophy
Rationale: Physiologic atrophy occurs with normal development. The shrinking of the
thymus gland during childhood and the shrinkage of the uterus after childbirth are
standard examples of the body reducing tissue that is no longer needed in its larger state.
Question 3
An echocardiogram of a patient with long-standing, untreated hypertension reveals a thickened
left ventricular wall. What specific cellular process is responsible for this finding?
A) Physiologic hypertrophy
B) Pathologic hyperplasia
, 2
C) Pathologic hypertrophy
D) Metaplasia
E) Dysplasia
Correct Answer: C) Pathologic hypertrophy
Rationale: Hypertrophy is an increase in the size of cells due to increased workload. In the
heart, untreated hypertension (high blood pressure) forces the left ventricle to pump
harder against higher resistance, leading to pathologic cardiomegaly. This is considered
pathologic because it occurs in response to a disease state and can eventually lead to heart
failure.
Question 4
A weightlifter experiences an increase in the size of their biceps muscles. This is categorized as:
A) Physiologic hypertrophy
B) Pathologic hypertrophy
C) Physiologic hyperplasia
D) Compensatory hyperplasia
E) Metaplasia
Correct Answer: A) Physiologic hypertrophy
Rationale: Physiologic hypertrophy is the result of increased demand that is not related to a
disease process, such as heavy physical exercise or the enlargement of the uterus during
pregnancy.
Question 5
Following a partial hepatectomy, the remaining liver cells begin to divide rapidly to restore the
organ's mass. This is an example of:
A) Pathologic hyperplasia
B) Physiologic hypertrophy
C) Physiologic hyperplasia
D) Dysplasia
E) Metaplasia
Correct Answer: C) Physiologic hyperplasia
Rationale: Hyperplasia is an increase in the number of cells due to increased cellular
, 3
division. Liver regeneration is a type of compensatory physiologic hyperplasia, allowing the
organ to regenerate and regain function after injury or surgery.
Question 6
A 50-year-old female presents with heavy menstrual bleeding. A biopsy shows an excessive
increase in the number of endometrial cells due to hormonal imbalance. This is known as:
A) Physiologic hyperplasia
B) Pathologic hyperplasia
C) Dysplasia
D) Metaplasia
E) Atrophy
Correct Answer: B) Pathologic hyperplasia
Rationale: Pathologic hyperplasia is an abnormal increase in cell number, usually caused
by excessive hormonal stimulation or the effects of growth factors on target cells.
Endometrial hyperplasia is a classic example often related to estrogen/progesterone
imbalance.
Question 7
A Pap smear returns with a diagnosis of "atypical hyperplasia" of the cervix, showing cells that
vary in size, shape, and organization. This is best described as:
B) Metaplasia
C) Dysplasia
D) Atrophy
E) Hypertrophy
Correct Answer: C) Dysplasia
Rationale: Dysplasia refers to abnormal changes in the size, shape, and organization of
mature cells. It is often called "atypical hyperplasia." While it is not a true adaptive
process, it is strongly associated with neoplastic growth (cancer) and is commonly seen in
the cervix in response to HPV infection.
Question 8
A long-term cigarette smoker undergoes a bronchial biopsy. The results show that the normal
, 4
ciliated columnar epithelium has been replaced by stratified squamous epithelium. This
reversible process is:
A) Dysplasia
B) Hyperplasia
C) Metaplasia
D) Atrophy
E) Oncosis
Correct Answer: C) Metaplasia
Rationale: Metaplasia is the reversible replacement of one mature cell type by another,
sometimes less differentiated, cell type. It involves the reprogramming of stem cells. In
smokers, squamous cells replace columnar cells because they can better survive the harsh
smoke environment, though they lose the protective cilia function.
Question 9
What is the primary pathophysiology behind cell death in hypoxic injury?
A) Increase in ATP production
B) Decrease in mitochondrial function and ATP production
C) Decrease in anaerobic metabolism
D) Increase in intracellular potassium
E) Shrinkage of the nucleus
Correct Answer: B) Decrease in mitochondrial function and ATP production
Rationale: Hypoxia (lack of oxygen) leads to a decrease in mitochondrial function, which
drastically reduces ATP production. Without ATP, the sodium-potassium pump fails,
leading to intracellular swelling and the switch to anaerobic metabolism, which creates
lactic acid and eventually leads to cell death.
Question 10
A patient presents with cyanosis, cognitive impairment, and lethargy. These are classic clinical
manifestations of:
A) Ethanol toxicity
B) Hypercalcemia
C) Hypoxia injury
