NR 507 Advanced Pathophysiology Final Exam 2025/2026
Question 1: What is the primary cellular mechanism in apoptosis?
A) Necrosis
B) Programmed cell death
C) Autophagy
D) Mitosis
B) Programmed cell death
Rationale: Apoptosis is a regulated process of programmed cell death that maintains tissue
homeostasis and eliminates damaged cells without inflammation.
Question 2: Which genetic disorder is caused by a trinucleotide repeat expansion?
A) Cystic fibrosis
B) Huntington's disease
C) Sickle cell anemia
D) Tay-Sachs disease
B) Huntington's disease
,Rationale: Huntington's disease results from CAG repeat expansion in the HTT gene, leading
to neurodegeneration.
Question 3: What is the hallmark of acute inflammation?
A) Fibrosis
B) Vascular permeability
C) Granulation tissue
D) Lymphocyte infiltration
B) Vascular permeability
Rationale: Acute inflammation involves increased vascular permeability and exudate
formation as initial responses.
Question 4: Which immune cell is primarily responsible for antibody production?
A) T lymphocyte
B) B lymphocyte
C) Macrophage
D) Neutrophil
B) B lymphocyte
Rationale: B lymphocytes differentiate into plasma cells that produce antibodies in humoral
immunity.
Question 5: What is the most common cause of heart failure?
A) Valvular disease
B) Coronary artery disease
C) Hypertension
D) Cardiomyopathy
B) Coronary artery disease
Rationale: Coronary artery disease leads to myocardial infarction and subsequent systolic
dysfunction.
Question 6: Which pathophysiological change occurs in asthma?
A) Bronchial dilation
B) Airway hyperresponsiveness and inflammation
C) Alveolar destruction
D) Pulmonary fibrosis
B) Airway hyperresponsiveness and inflammation
Rationale: Asthma involves IgE-mediated inflammation and bronchoconstriction.
Question 7: What hormone deficiency causes type 1 diabetes mellitus?
A) Insulin
B) Glucagon
C) Cortisol
D) Thyroxine
A) Insulin
Rationale: Autoimmune destruction of beta cells results in absolute insulin deficiency.
, Question 8: Which neurotransmitter imbalance is associated with Parkinson's
disease?
A) Dopamine deficiency
B) Serotonin excess
C) GABA excess
D) Acetylcholine deficiency
A) Dopamine deficiency
Rationale: Loss of dopaminergic neurons in the substantia nigra causes motor symptoms.
Question 9: What is the primary mechanism of acute kidney injury in prerenal
azotemia?
A) Glomerular damage
B) Decreased renal perfusion
C) Tubular necrosis
D) Interstitial inflammation
B) Decreased renal perfusion
Rationale: Prerenal AKI results from hypoperfusion, leading to reduced GFR.
Question 10: Which process involves the proliferation of fibroblasts in wound
healing?
A) Hemostasis
B) Inflammation
C) Proliferation
D) Remodeling
C) Proliferation
Rationale: Proliferation phase features fibroblast migration and collagen synthesis.
Question 11: What genetic mutation is characteristic of cystic fibrosis?
A) CFTR delta F508
B) BRCA1
C) HbS
D) Trisomy 21
A) CFTR delta F508
Rationale: The delta F508 mutation in CFTR causes defective chloride transport.
Question 12: Which cytokine is central to the inflammatory response?
A) IL-1
B) TNF-alpha
C) IL-10
D) IL-4
A) IL-1
Rationale: IL-1 promotes fever, leukocyte activation, and acute phase response.
Question 13: What is the primary cause of atherosclerosis?
A) Endothelial injury
B) Smooth muscle proliferation
C) Lipid accumulation
