[SECTION 1: Cellular & Genetic Pathophysiology — Questions 1-12]
Q1: A patient presents with acute pancreatitis. The pathophysiology involves the activation of
pancreatic enzymes leading to autodigestion. Which specific type of cell necrosis is most
characteristic of this condition?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Fat necrosis
D. Fibrinoid necrosis
Correct Answer: C
Rationale: Fat necrosis is specific to tissues with high lipid content, such as the breast and
pancreas. In acute pancreatitis, lipases are released into the surrounding tissue, hydrolyzing
triglycerides into fatty acids. These fatty acids combine with calcium to form chalky, white
deposits (saponification). Coagulative necrosis (A) is typical of ischemic injury in solid organs
(heart, kidney). Liquefactive necrosis (B) occurs in the brain due to enzymatic digestion.
Fibrinoid necrosis (D) is seen in immune complex vascular injury.
Q2: A 45-year-old male presents with angina and is found to have a specific chromosomal
translocation t(9;22). This genetic anomaly results in the formation of the Philadelphia
chromosome and is the pathophysiologic basis for which disease?
A. Acute Lymphoblastic Leukemia (ALL)
C. Chronic Myeloid Leukemia (CML)
D. Burkitt Lymphoma
Correct Answer: C
,2
Rationale: The Philadelphia chromosome results from a reciprocal translocation between
chromosomes 9 and 22, t(9;22). This translocation creates the BCR-ABL fusion gene, which
encodes a constitutively active tyrosine kinase that drives uncontrolled myeloid cell proliferation.
While t(9;22) can occur in some ALL cases, it is the defining pathophysiologic hallmark of
Chronic Myeloid Leukemia (CML). Burkitt lymphoma (D) is associated with t(8;14).
Q3: A pathologist is examining a tissue sample showing a change from one type of mature cell to
another type of mature cell. This cellular adaptation is most likely:
A. Hyperplasia
B. Dysplasia
C. Metaplasia
D. Anaplasia
Correct Answer: C
Rationale: Metaplasia is a reversible cellular adaptation where one differentiated cell type is
replaced by another, usually in response to chronic stress or irritation, to better withstand the
environment (e.g., columnar epithelium changing to squamous in the smoker's trachea).
Hyperplasia (A) is an increase in the number of cells. Dysplasia (B) is disordered cell growth
with potential progression to cancer. Anaplasia (D) refers to a loss of differentiation in cancer
cells.
Q4: Which mechanism of cell injury involves the failure of the sodium-potassium pump
(Na+/K+-ATPase) leading to cellular swelling?
A. Hypoxic injury
C. Ischemic injury
D. Immunologic injury
Correct Answer: C
Rationale: Ischemia (loss of blood flow) leads to hypoxia, which causes depletion of ATP.
Without ATP, the sodium-potassium pump fails, allowing sodium and water to influx into the cell
while potassium leaks out. This results in hydropic degeneration (cellular swelling). While
hypoxia (A) is the lack of oxygen, ischemia includes the lack of nutrients and the buildup of
,3
waste products, initiating the pump failure more aggressively than pure hypoxia alone. Free
radical injury (B) involves oxidative damage. Immunologic injury (D) involves immune
complexes.
Q5: A patient has a diagnosis of Huntington's disease. The nurse knows this condition follows
which pattern of inheritance?
A. Autosomal Recessive
C. Autosomal Dominant
D. X-linked Recessive
Correct Answer: C
Rationale: Huntington's disease is an autosomal dominant disorder, meaning only one copy of
the mutated gene (on an autosome, not a sex chromosome) is sufficient for the individual to be
affected. Autosomal recessive (A) requires two copies (e.g., Cystic Fibrosis). X-linked recessive
(D) primarily affects males and is carried by females (e.g., Hemophilia).
Q6: Apoptosis is a process of programmed cell death. Which of the following is a physiologic
(normal) example of apoptosis?
A. Cell death in the center of a myocardial infarction
C. Elimination of self-reactive lymphocytes
D. Liver necrosis due to acetaminophen toxicity
Correct Answer: C
Rationale: Apoptosis is a controlled, energy-dependent process. The elimination of self-reactive
lymphocytes in the thymus (negative selection) is a physiologic mechanism to prevent
autoimmune disease. Myocardial infarction (A) and acetaminophen toxicity (D) are examples of
pathologic necrosis (uncontrolled cell death). Viral hepatitis (B) can trigger apoptosis but is
pathologic.
Q7: A patient with Down syndrome (Trisomy 21) is being assessed. This genetic disorder is
caused by:
, 4
A. Deletion of a chromosome
C. Nondisjunction
D. Translocation
Correct Answer: C
Rationale: Down syndrome is most commonly caused by meiotic nondisjunction, resulting in an
extra copy of chromosome 21 (three copies instead of two). While translocation (D) can cause
Down syndrome (familial type), nondisjunction accounts for 95% of cases. Deletion (A) involves
loss of a genetic segment (e.g., Cri-du-chat). Mosaicism (B) is another mechanism but less
common than nondisjunction.
Q8: In a patient with sickle cell anemia, a point mutation leads to the substitution of valine for
glutamic acid in the hemoglobin chain. What is the specific term for this type of mutation?
A. Frameshift mutation
B. Nonsense mutation
C. Missense mutation
D. Silent mutation
Correct Answer: C
Rationale: A missense mutation is a point mutation that results in a codon that codes for a
different amino acid. In sickle cell anemia, the substitution of glutamic acid with valine alters the
properties of hemoglobin, causing it to polymerize under low oxygen conditions. A nonsense
mutation (B) creates a stop codon. A frameshift mutation (A) alters the reading frame. A silent
mutation (D) changes the codon but not the amino acid.
Q9: A patient suffers a stroke and has significant brain tissue death. The brain undergoes
liquefactive necrosis because:
A. Brain cells have high regenerative capacity.
C. Brain tissue is rich in hydrolytic enzymes.
D. The blood-brain barrier prevents inflammation.
