,Q1. A patient presents with structural changes in the lower esophagus due to chronic
acid reflux. The normal squamous epithelium has been replaced by columnar
epithelial cells. What cellular adaptation does this represent?
A) Hyperplasia
B) Dysplasia
C) Metaplasia
D) Atrophy
C) Metaplasia
Rationale: Metaplasia is the reversible replacement of one mature cell type by
another mature cell type, frequently occurring in response to chronic irritation like
gastroesophageal reflux disease (GERD).
Q2. A nurse is caring for a patient with a large, non-healing lower extremity wound.
Granulation tissue is forming, requiring a high rate of mitotic division. Which cellular
process describes this increase in the total number of cells?
A) Hypertrophy
B) Hyperplasia
C) Anaplasia
D) Neoplasia
B) Hyperplasia
Rationale: Hyperplasia is an increase in the number of cells within an organ or
tissue, resulting from an increased rate of cellular division, which is essential during
normal wound healing.
Q3. An autopsy of an elderly patient reveals a decrease in the overall mass and size
of the brain tissue. What is the correct term for this specific cellular adaptation to
aging and decreased metabolic demand?
A) Atrophy
B) Metaplasia
C) Dysplasia
D) Hypertrophy
A) Atrophy
Rationale: Atrophy is a decrease or shrinkage in cellular size. When it occurs in a
large number of cells, the entire organ shrinks, which is commonly seen in brain
tissue during advanced aging.
Q4. A biopsy of the cervix reveals abnormal variations in cellular size, shape, and
organization, along with an increased rate of mitosis. How should the nurse classify
these specific cellular changes?
A) Metaplasia
B) Dysplasia
C) Hypertrophy
D) Hyperplasia
B) Dysplasia
Rationale: Dysplasia refers to abnormal changes in the size, shape, and organization
of mature cells. It is not a true adaptation and is frequently considered a
precancerous change.
Q5. During an ischemic event, a lack of oxygen leads to a rapid decline in cellular
ATP production. Which immediate consequence occurs due to the failure of the
2|Page
,active sodium-potassium transport pump?
A) Intracellular accumulation of potassium
B) Severe cellular dehydration and shrinkage
C) Influx of sodium and water into the cell
D) Increased extracellular fluid volume
C) Influx of sodium and water into the cell
Rationale: When ATP is depleted, the Na+/K+ ATPase pump fails. Sodium
accumulates inside the cell, creating an osmotic gradient that pulls water inward,
causing acute cellular swelling.
Q6. A patient undergoes a tissue biopsy that reveals cellular death characterized by
nuclear dissolution, severe cell membrane rupture, and the release of intracellular
contents triggering local inflammation. What type of cell death is this?
A) Apoptosis
B) Autophagy
C) Necrosis
D) Atrophy
C) Necrosis
Rationale: Necrosis is characterized by rapid cell swelling, membrane rupture, and
the spillage of lysosomal enzymes into surrounding tissues, which induces a
localized inflammatory response.
Q7. A nurse is reviewing a pathology report that details a process of programmed
cellular self-destruction. The cells shrink and are cleanly phagocytized without
causing inflammation to surrounding tissues. What is this process?
A) Autolysis
B) Apoptosis
C) Gangrene
D) Necrosis
B) Apoptosis
Rationale: Apoptosis is an active, genetically programmed process of cellular self-
destruction that removes worn-out or damaged cells cleanly without releasing
harmful inflammatory mediators.
Q8. A patient is diagnosed with a genetic condition characterized by the abnormal
accumulation of thick, sticky mucus in the lungs and pancreas. What is the primary
underlying genetic etiology of Cystic Fibrosis?
A) Autosomal dominant inheritance
B) Autosomal recessive inheritance
C) X-linked dominant inheritance
D) Chromosomal nondisjunction
B) Autosomal recessive inheritance
Rationale: Cystic Fibrosis is an autosomal recessive disorder caused by mutations in
the CFTR gene. An individual must inherit two copies of the defective gene to
manifest the clinical disease.
Q9. A physical assessment of an infant reveals low-set ears, a flat facial profile, an
upward slanting of the palpebral fissures, and a simian crease. What is the
chromosomal abnormality responsible for these findings?
A) Monosomy X
B) Trisomy 21
C) XXY Chromosome pattern
3|Page
, D) Trisomy 18
B) Trisomy 21
Rationale: Trisomy 21, or Down Syndrome, is caused by a chromosomal
nondisjunction resulting in three copies of chromosome 21, presenting with distinct
physical and cognitive features.
Q10. A female patient presents with a short stature, webbed neck, low posterior
hairline, and a broad chest with widely spaced nipples. A karyotype confirms the
diagnosis of Turner syndrome. What is her chromosomal composition?
A) 47, XXY
B) 46, XY
C) 45, X
D) 47, XXX
C) 45, X
Rationale: Turner syndrome is caused by an absence of all or part of the second sex
chromosome, resulting in a 45, X karyotype in females.
Q11. A 40-year-old patient is diagnosed with Huntington's disease, a progressive
neurological disorder. The patient notes that their biological father also died from the
disease. What type of inheritance pattern does this disease follow?
A) Autosomal dominant
B) Autosomal recessive
C) X-linked recessive
D) Mitochondrial inheritance
A) Autosomal dominant
Rationale: Huntington's disease is an autosomal dominant disorder, meaning only
one copy of the mutated gene (from one affected parent) is required to pass on the
condition.
Q12. During the vascular stage of acute inflammation, which chemical mediators are
primarily responsible for inducing immediate vasodilation and increasing capillary
permeability?
A) Interleukin-10 and Transforming Growth Factor
B) Histamine, bradykinin, and prostaglandins
C) Leukocidins and interferons
D) C-reactive protein and albumin
B) Histamine, bradykinin, and prostaglandins
Rationale: Histamine released by mast cells, along with bradykinin and
prostaglandins, dilates local blood vessels and expands endothelial junctions,
leading to local erythema, heat, and edema.
Q13. A patient's complete blood count (CBC) reveals a significant shift to the left
(increase in bands/immature neutrophils). What is the physiological significance of
this finding during an acute infection?
A) The bone marrow has depleted all immune defenses.
B) The infection is chronic and settling into standard remission.
C) The bone marrow is releasing immature neutrophils to meet a high demand.
D) The patient is developing an immediate allergic response.
C) The bone marrow is releasing immature neutrophils to meet a high demand.
Rationale: A "left shift" indicates that the body's acute inflammatory demand is high,
prompting the bone marrow to prematurely release immature neutrophils (bands) to
combat an active infection.
