1. Advanced Cellular Pathophysiology & Genetics
1. A patient presents with severe ischemia to the lower extremity. At the cellular
level, a lack of oxygen directly causes a failure of the \(Na^{+}/K^{+}\) ATPase
pump. What is the immediate consequence of this failure?
o A) Cellular dehydration and shrinkage
o B) Increased intracellular calcium concentration and cell swelling
o C) Hyperpolarization of the cell membrane
o D) Structural stability of the lysosomal membranes
o Correct Answer: B) Increased intracellular calcium concentration and cell swelling
,o Rationale: Ischemia drops ATP levels, shutting down the \(Na^{+}/K^{+}\) pump.
Sodium rushes into the cell, drawing water with it, causing acute cellular
swelling. Concurrently, the calcium-pump fails, driving intracellular calcium
upwards, which activates destructive cellular enzymes.
2. During an autophagic cellular process, which organelle is responsible for
degrading cellular components via acid hydrolases?
o A) Peroxisome
o B) Lysosome
o C) Ribosome
o D) Golgi apparatus
o Correct Answer: B) Lysosome
o Rationale: Lysosomes contain acidic digestive enzymes (acid hydrolases) that
break down worn-out organelles, proteins, and foreign invaders during
autophagy or phagocytosis.
3. A patient with chronic hypertension demonstrates significant enlargement of
the left ventricular myocardial cells without an increase in cell number. This
cellular adaptation is best described as:
o A) Hyperplasia
o B) Metaplasia
o C) Hypertrophy
o D) Dysplasia
o Correct Answer: C) Hypertrophy
o Rationale: Hypertrophy is an increase in the size of individual cells in response
to mechanical load or stress, typical in cardiac muscle cells which cannot
undergo mitosis (hyperplasia).
4. Which type of cellular necrosis is characteristically seen in hypoxic injury to the
brain or central nervous system?
o A) Coagulative necrosis
o B) Liquefactive necrosis
o C) Caseous necrosis
o D) Fat necrosis
o Correct Answer: B) Liquefactive necrosis
o Rationale: Hypoxic death of cells in the CNS results in liquefactive necrosis
because brain tissue is rich in hydrolytic enzymes and lipids, transforming the
tissue into a liquid mass.
5. A biopsy of the bronchus from a patient with a long history of cigarette
smoking reveals that normal ciliated columnar epithelium has been replaced by
stratified squamous epithelium. What is this adaptation called?
o A) Anaplasia
o B) Dysplasia
o C) Metaplasia
o D) Hyperplasia
o Correct Answer: C) Metaplasia
o Rationale: Metaplasia is the reversible replacement of one mature cell type by
another mature cell type, usually driven by chronic irritation or inflammation.
, 6. Which genetic disorder is characterized by a karyotype displaying a single X
chromosome (\(45, X\)) and clinically presents with short stature and webbed
neck?
o A) Klinefelter syndrome
o B) Down syndrome
o C) Turner syndrome
o D) Fragile X syndrome
o Correct Answer: C) Turner syndrome
o Rationale: Turner syndrome is a female chromosomal condition caused by
complete or partial monosomy of the X chromosome (\(45, X\)).
7. A patient is diagnosed with an autosomal dominant disorder. If the affected
parent is heterozygous and the other parent is unaffected, what is the
probability that their child will inherit the condition?
o A) 25%
o B) 50%
o C) 75%
o D) 100%
o Correct Answer: B) 50%
o Rationale: Heterozygous dominant (\(Aa\)) crossed with unaffected recessive
(\(aa\)) yields a 50% chance of offspring inheriting the dominant mutant allele
(\(Aa\)).
8. Huntington disease is a neurodegenerative disorder characterized by an
abnormal expansion of which trinucleotide repeat sequence?
o A) CGG
o B) CAG
o C) GAA
o D) CTG
o Correct Answer: B) CAG
o Rationale: Huntington disease is caused by an expansion of the CAG
trinucleotide repeat in the HTT gene, leading to an abnormally long
polyglutamine tract in the huntingtin protein.
9. Which process describes the silencing of an allele from one parent via DNA
methylation during gametogenesis?
o A) Mosaicism
o B) Genomic Imprinting
o C) Anticipation
o D) Penetrance
o Correct Answer: B) Genomic Imprinting
o Rationale: Genomic imprinting is an epigenetic process where gene expression
is determined by the parent of origin, usually via DNA methylation that silences
either the maternal or paternal allele.
10. Epigenetic modifications change the expression of genes without altering
what?
o A) RNA processing
o B) Protein translation
