Advanced Pathophysiology | Questions and Verified Answers | 100%
Correct | Grade A
Latest Updated | Wilkes University Graduate Nursing
This comprehensive study guide presents a 130-question, verified examination aligned with the Wilkes
University NSG 530 Advanced Pathophysiology Exam 2 content blueprint. It is organized into ten content
domains spanning cellular injury, adaptation, and death; inflammation and wound healing; immunity and
hypersensitivity; immunodeficiency, autoimmunity, and transplantation; infection pathogenesis; fluid and
electrolyte alterations; acid-base pathophysiology; cardiovascular pathophysiology; respiratory and renal
pathophysiology; and genetic and neoplastic pathophysiology. Cognitive levels are calibrated to graduate
advanced pathophysiology standards (approximately 30% recall of mechanisms and definitions, 50%
application through scenario-based pathophysiologic reasoning, and 20% analysis involving multi-system
integration and clinical correlation). Every question is followed by a single best answer, a clearly identified
correct option marked [CORRECT], and a detailed verified rationale that integrates advanced
pathophysiologic mechanisms, cellular processes, compensatory responses, and clinical correlation.
Mechanism-focused "Which pathophysiologic mechanism BEST explains..." questions emphasize causal
reasoning at the Wilkes NSG 530 standard. Use this guide for self-assessment, mechanism-based learning,
and comprehensive preparation for NSG 530 Exam 2.

Section 1: Cellular Injury, Adaptation, and Death
Section 1 — Cellular Injury, Adaptation, and Death
Hypoxia, Ischemia, Free Radical Injury, Necrosis, Apoptosis, and Autophagy
Domain coverage: Hypoxia, Ischemia, Free Radical Injury, Necrosis, Apoptosis, and Autophagy
Q1: A 65-year-old man with chronic gastroesophageal reflux disease undergoes endoscopy, revealing that
the normal stratified squamous epithelium of the distal esophagus has been replaced by intestinal-type
columnar epithelium with goblet cells. Which pathophysiologic mechanism BEST explains this finding?
A. Hypertrophy, an increase in cell size due to increased workload
B. Hyperplasia, an increase in cell number due to hormonal stimulation
C. Metaplasia, the reversible replacement of one differentiated cell type by another in response to
chronic injury, representing an adaptive substitution [CORRECT]
D. Dysplasia, disordered cellular growth and atypia representing a preneoplastic change
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one differentiated adult cell type by another, occurring in response
to chronic injury as an adaptive substitution. The classic example is Barretts esophagus, in which chronic acid exposure
causes stratified squamous epithelium to be replaced by intestinal-type columnar epithelium with goblet cells, which is
more resistant to acid but carries increased malignant potential. Hypertrophy (Option A) increases cell size (e.g., cardiac
myocytes in HTN). Hyperplasia (Option B) increases cell number (e.g., endometrial hyperplasia from estrogen). Dysplasia
(Option D) is disordered growth with atypia (a true preneoplastic change, not an adaptive substitution). Clinical
correlation: Barretts carries a 30- to 50-fold increased risk of esophageal adenocarcinoma, requiring surveillance
endoscopy.
Q2: A 70-year-old woman with long-standing hypertension has an echocardiogram demonstrating
increased left ventricular wall thickness with normal cavity size. The cardiac myocytes microscopically
show increased size with no change in number. Which cellular adaptation BEST explains this finding?
A. Hyperplasia, an increase in cell number due to hormonal stimulation
B. Hypertrophy, an increase in cell size due to increased functional demand or trophic signals,
occurring in tissues incapable of cell division (cardiac myocytes) [CORRECT]
C. Metaplasia, replacement of one cell type by another
D. Dysplasia, disordered cellular growth
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size (not number) due to increased functional demand or trophic
stimulation. Cardiac myocytes are terminally differentiated and cannot divide, so they respond to pressure overload
(HTN) by hypertrophy, increasing myofibrils and sarcomeres. Left ventricular concentric hypertrophy (increased wall
thickness, normal cavity) is the classic adaptation to pressure overload. Hyperplasia (Option A) increases cell number
(occurs in tissues capable of mitosis: endometrium, prostate). Metaplasia (Option C) is cell-type substitution. Dysplasia
(Option D) is preneoplastic change. Clinical correlation: Initially compensatory, chronic hypertrophy progresses to
decompensation with dilation and heart failure as capillary density fails to match myocyte growth, causing relative
ischemia and fibrosis.
