SECTION A: Foundational Pathophysiology and Cellular
Adaptation (Questions 1-20)
1. A patient with chronic anemia develops cardiac
enlargement. This type of cellular adaptation is best
described as:
A) Atrophy
B) Hypertrophy
C) Hyperplasia
D) Metaplasia
Correct Answer: B) Hypertrophy
Expert Rationale: Hypertrophy is an increase in cell size in response
to increased workload or demand. In chronic anemia, the heart
must work harder to pump oxygen-carrying blood, leading to
myocardial hypertrophy. Unlike hyperplasia (increased cell
number) or metaplasia (replacement of one cell type with another),
hypertrophy involves enlargement of existing cells .
2. A 45-year-old female with a history of chronic acid reflux
develops changes in the epithelial lining of her esophagus.
,The normal stratified squamous epithelium is replaced by
columnar epithelium. This cellular adaptation is known as:
A) Dysplasia
B) Hyperplasia
C) Metaplasia
D) Anaplasia
Correct Answer: C) Metaplasia
Expert Rationale: Metaplasia is the reversible replacement of one
differentiated cell type with another, often in response to chronic
irritation. Barrett's esophagus, a complication of GERD, represents
metaplasia of esophageal epithelium. Dysplasia (abnormal cell
growth) and anaplasia (loss of differentiation, characteristic of
cancer) are distinct processes .
3. What type of abnormal cell growth does carcinoma refer
to?
A) Connective tissue cells
B) Epithelial cells
C) Muscle cells
D) Lymphoid tissue cells
Correct Answer: B) Epithelial cells
Expert Rationale: Carcinoma refers to dysplastic epithelial cells that
have penetrated the entire thickness of the epithelium into the
basement membrane. This is the most common type of cancer,
arising from epithelial tissues including skin, glandular tissues, and
internal organ linings .
,4. Which characteristic is indicative of a malignant tumor?
A) Well-organized tissue structure
B) Absence of normal tissue organization
C) Encapsulation
D) Slow growth
Correct Answer: B) Absence of normal tissue organization
Expert Rationale: Malignant tumors lack normal tissue
organization. Healthy tissue consists of non-cancerous cells that are
well-differentiated and connected via well-organized stroma.
Malignant cells demonstrate uncontrolled growth, invasion, and
lack of normal architectural organization .
5. Which lifestyle factor has NOT been linked to the
development of cancer?
A) Tobacco use
B) Alcohol consumption
C) Extreme exercise
D) Obesity
Correct Answer: C) Extreme exercise
Expert Rationale: Tobacco use, obesity, and alcohol consumption
are causal for numerous cancers. Exercise helps prevent colon
cancer and likely helps prevent endometrial, breast, and other
cancers. Regular physical activity is protective rather than
carcinogenic .
, 6. Which pediatric malignancy is linked to the family of
origin?
A) Leukemia
B) Wilms tumor
C) Liver cancer
D) Cervical cancer
Correct Answer: B) Wilms tumor
Expert Rationale: Wilms tumor is kidney cancer in childhood caused
by inherited genes. The main causes of liver cancer are hepatitis,
fatty liver disease, and alcohol use. The main cause of cervical
cancer is HPV infection. Leukemia is caused by mutations to
hematopoietic stem cells .
7. Which of the following drugs is classified as hormonal
treatment for breast cancer?
A) Tamoxifen
B) Paclitaxel
C) Rituximab
D) Lapatinib
Correct Answer: A) Tamoxifen
Expert Rationale: Tamoxifen is an anti-estrogen medication used in
the treatment of estrogen-linked breast cancer. Lapatinib is a
tyrosine kinase inhibitor, Paclitaxel is an antimicrotubule agent,
and Rituximab is a CD20-directed cytolytic monoclonal antibody .
