PATHOPHYSIOLOGIC CELLULAR ADAPTATION, INFLAMMATION & IMMUNE RESPONSE
Q1. A 58-year-old patient with chronic hypertension develops left ventricular
hypertrophy after years of increased cardiac workload. Which cellular adaptation best
,explains this finding?
A. Hyperplasia
B. Dysplasia
C. Hypertrophy
D. Metaplasia
Correct Answer: 🔴 C. Hypertrophy
Explanation: 🔹 Hypertrophy refers to an increase in cell size resulting in enlargement of
an organ or tissue. Cardiac muscle cells cannot readily divide; therefore, chronic pressure
overload from hypertension causes myocardial cells to enlarge rather than increase in
number. Hyperplasia involves increased cell numbers, dysplasia indicates abnormal
cellular growth patterns, and metaplasia refers to replacement of one mature cell type
with another. The myocardium specifically responds to chronic increased workload
through hypertrophy, making option C correct.
Q2. A patient with septic shock develops widespread endothelial injury and capillary
leakage. Which inflammatory mediator is most directly responsible for increasing
vascular permeability during acute inflammation?
A. Histamine
B. Erythropoietin
C. Insulin
D. Albumin
Correct Answer: 🔴 A. Histamine
Explanation: 🔹 Histamine is released primarily from mast cells and basophils during
acute inflammation. It causes vasodilation and increased vascular permeability, leading
to edema and migration of leukocytes into injured tissues. Erythropoietin regulates red
blood cell production, insulin controls glucose metabolism, and albumin maintains
oncotic pressure rather than initiating inflammatory vascular changes. Histamine is
therefore the key mediator responsible for early inflammatory vascular permeability.
,Q3. A nurse practitioner evaluates a patient with systemic lupus erythematosus (SLE).
The disease process is best classified under which hypersensitivity reaction?
A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
Correct Answer: 🔴 C. Type III hypersensitivity
Explanation: 🔹 SLE is primarily a type III hypersensitivity disorder characterized by
immune complex deposition in tissues, leading to complement activation and
inflammation. Type I reactions involve IgE-mediated allergy, type II reactions involve
antibody-mediated cytotoxicity, and type IV reactions are delayed T-cell-mediated
responses. In SLE, circulating antigen-antibody complexes deposit in organs such as the
kidneys, skin, and joints, producing systemic manifestations.
Q4. A patient exposed to ionizing radiation experiences DNA damage and impaired
cellular replication. Which phase of the cell cycle is most vulnerable to radiation-
induced injury?
A. G0 phase
B. S phase
C. Mitosis
D. G1 phase
Correct Answer: 🔴 C. Mitosis
Explanation: 🔹 Cells are most radiosensitive during mitosis because chromosomal
material is highly exposed and actively dividing. Radiation disrupts DNA integrity and
chromosomal segregation during this stage. Cells in resting phases such as G0 are more
resistant. Although DNA synthesis occurs in the S phase, mitosis remains the most
vulnerable stage for catastrophic radiation injury. Rapidly dividing tissues therefore
exhibit higher susceptibility to radiation damage.
, Q5. A patient develops a fever following bacterial pneumonia. Which cytokine is
primarily responsible for resetting the hypothalamic temperature set point?
A. Interleukin-1
B. Hemoglobin
C. Acetylcholine
D. Calcitonin
Correct Answer: 🔴 A. Interleukin-1
Explanation: 🔹 Interleukin-1 (IL-1), along with tumor necrosis factor (TNF), acts as an
endogenous pyrogen that stimulates prostaglandin production in the hypothalamus,
raising body temperature during infection. Hemoglobin transports oxygen, acetylcholine
functions as a neurotransmitter, and calcitonin regulates calcium metabolism. IL-1 is
therefore the inflammatory mediator most directly associated with fever generation
during infection.
Q6. A 45-year-old smoker undergoes bronchoscopy revealing replacement of normal
ciliated columnar epithelium with stratified squamous epithelium. Which process has
occurred?
A. Anaplasia
B. Hyperplasia
C. Metaplasia
D. Necrosis
Correct Answer: 🔴 C. Metaplasia
Explanation: 🔹 Metaplasia is a reversible adaptive substitution of one mature cell type
for another better suited to tolerate chronic irritation. Smoking commonly causes
respiratory epithelium to transform into stratified squamous epithelium. Anaplasia refers
to undifferentiated malignant cells, hyperplasia is increased cell number, and necrosis is
cell death. Chronic smoke exposure specifically induces squamous metaplasia in the
airways.
