MODULE I: CELLULAR MECHANISMS, KINETICS, &
GENETIC ALTERATIONS
Question 1
A PMHNP/FNP is reviewing cellular adaptations in a biopsy report of a client with
chronic gastroesophageal reflux disease (GERD). The report notes that the normal
stratified squamous epithelium of the lower esophagus has been replaced by simple
columnar epithelium. The nurse practitioner should identify this structural alteration as:
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: C. Metaplasia
Rationale: Metaplasia is a reversible cellular adaptation where one mature cell type is
replaced by another mature cell type, often in response to chronic irritation or
inflammation. In Barrett's esophagus (secondary to chronic GERD), the squamous cells
adapt to the acidic environment by changing into columnar cells. Dysplasia represents
abnormal, disordered cell growth and is a pre-cancerous lesion, not a mature cell
substitution.
Question 2
During a cellular injury sequence, a profound deficiency of oxygen leads to a decrease
in mitochondrial ATP production. This state directly causes the failure of the sodium-
potassium pump (Na⁺/K⁺ ATPase), resulting in which initial cellular event?
,A. Intracellular dehydration and cellular shrinkage
B. Intracellular accumulation of sodium and water, leading to acute acute cellular
swelling (oncosis).
C. Immediate, irreversible cell replication
D. Rapid extracellular crystallization of potassium
Correct Answer: B. Intracellular accumulation of sodium and water, leading to
acute cellular swelling (oncosis).
Rationale: When ATP levels fall due to hypoxia, the Na⁺/K⁺ ATPase pump fails. Sodium
accumulates inside the cell, creating an osmotic gradient that draws water into the
intracellular compartment. This causes acute cellular swelling (oncosis) and dilation of
the endoplasmic reticulum.
Question 3
Which type of cell death is characterized by localized tissue self-destruction that triggers
an acute inflammatory response, often showing "coagulative" patterns inside myocardial
tissue following an ischemic infarction?
A. Apoptosis
B. Necrosis
C. Autophagy
D. Senescence
Correct Answer: B. Necrosis
Rationale: Necrosis is unregulated, accidental cell death caused by severe injury. It
involves cellular membrane rupture, leaking of intracellular contents into the surrounding
tissue, and the recruitment of inflammatory cells. Apoptosis is programmed, regulated
cell death that does not breach the cell membrane and does not trigger inflammation.
Question 4
A 4-year-old child with a genetic deletion on the long arm of chromosome 15 presents
with severe hyperphagia, obesity, cognitive delays, and hypogonadism. If this mutation
is inherited from the father, the disorder is known as Prader-Willi syndrome. This
genetic process is an example of:
A. X-linked recessive inheritance
B. Autosomal dominant penetrance
C. Genomic Imprinting
D. Chromosomal mosaicism
Correct Answer: C. Genomic Imprinting
, Rationale: Genomic imprinting is an epigenetic process where gene expression
depends on the parent of origin. Prader-Willi syndrome occurs when the paternal copy
of chromosome 15 (q11-q13) is deleted or unexpressed. If the maternal copy is deleted
or unexpressed instead, it results in Angelman syndrome.
Question 5
Which of the following descriptions accurately defines the cellular role of proto-
oncogenes in normal physiological tissue environments?
A. They actively cause cellular apoptosis during toxic exposures.
B. They encode proteins that stimulate normal, regulated cellular growth and
proliferation before mutating into oncogenes.
C. They function as absolute permanent structural anchors inside cellular walls.
D. They slow down cellular division lines to protect tissue from tumor spread.
Correct Answer: B. They encode proteins that stimulate normal, regulated cellular
growth and proliferation before mutating into oncogenes.
Rationale: Proto-oncogenes are normal genes that regulate cell division, growth, and
differentiation. When mutated or overexpressed, they become oncogenes, which drive
unregulated, autonomous cell division and tumor development.
MODULE II: CARDIOVASCULAR DISRUPTIONS &
PERFUSION COEFFICIENTS
Question 6
A client with a long history of poorly controlled essential hypertension presents with
progressive dyspnea on exertion. An echocardiogram confirms Left Ventricular
Hypertrophy. The advanced practice nurse understands that this cellular shift is driven
by which mechanism?
A. An absolute increase in the total number of myocardial cells.
B. An increase in the size of individual myocardial cells in response to a chronic
increase in afterload.
C. Deposition of dense adipose tissue matrices inside the valve rings.
D. Reversible metaplastic conversion of smooth muscle cells.
Correct Answer: B. An increase in the size of individual myocardial cells in
response to a chronic increase in afterload.
Rationale: Myocardial cells are permanent cells that cannot divide to create new cells
(hyperplasia). When faced with chronic high systemic vascular resistance (increased
