PATHOPHYSIOLOGY | COMPREHENSIVE REVIEW QUESTIONS,
ANSWERS & RATIONALES | LATEST UPDATE THIS YEAR PDF.
CORE DOMAINS
• Cellular Adaptation, Injury, and Death
• Inflammation, Immunity, and Hypersensitivity
• Genetic and Developmental Disorders
• Fluid, Electrolyte, and Acid-Base Imbalances
• Cardiovascular Pathophysiology
• Pulmonary Pathophysiology
• Renal and Genitourinary Pathophysiology
• Endocrine and Metabolic Disorders
• Hematologic and Oncologic Disorders
• Neurologic and Musculoskeletal Pathophysiology
INTRODUCTION
The NR507 Final Exam for Advanced Pathophysiology at Chamberlain
University is designed to evaluate the graduate nursing student's mastery of
complex disease mechanisms and their clinical applications. This
comprehensive assessment evaluates knowledge of cellular biology, genetic
control, immune and inflammatory responses, and the pathophysiology of
major body systems. The examination employs multiple-choice and scenario-
based questions that emphasize real-world clinical application, critical
thinking, and evidence-based decision-making. It rigorously assesses the ability
to synthesize pathophysiological concepts, interpret clinical findings, and
apply disease mechanisms to patient care, ensuring readiness for advanced
practice nursing roles.
,SECTION ONE: QUESTIONS 1–100
1. A common event during cellular reproduction resulting in the
constant occurrence of isolated cancer cells is known as:
A. Apoptosis
B. Cell transformation
C. Metastasis
D. Angiogenesis
B. Cell transformation
RATIONALE: Cell transformation is the process by which normal cells
acquire genetic mutations leading to uncontrolled growth and cancerous
behavior, occurring frequently even in healthy tissues. Apoptosis (A) is
programmed cell death. Metastasis (C) is the spread of cancer cells to distant
sites. Angiogenesis (D) is the formation of new blood vessels.
2. Which of the following best describes the function of a stem cell?
A. A fully differentiated cell with specialized function
B. An immature, undifferentiated cell capable of infinite division when
stimulated
C. A cell that has lost its ability to divide
D. A cell that only exists during embryonic development
B. An immature, undifferentiated cell capable of infinite division when
stimulated
RATIONALE: Stem cells are undifferentiated cells with self-renewal
capacity and the potential to differentiate into various specialized cell types
when appropriately stimulated. They are not fully differentiated (A) and do
not lose their ability to divide (C). They exist in both embryonic and adult
tissues (D).
,3. A patient with chronic hypertension develops left ventricular
hypertrophy. This adaptation is:
A. Metaplasia
B. Hyperplasia
C. Hypertrophy
D. Dysplasia
C. Hypertrophy
RATIONALE: Cardiac myocytes enlarge in response to increased
workload, resulting in hypertrophy. Metaplasia (A) is the replacement of one
cell type with another. Hyperplasia (B) is an increase in cell number.
Dysplasia (D) is disordered cellular growth.
4. Which cellular process is responsible for eliminating damaged cells
without triggering inflammation?
A. Necrosis
B. Apoptosis
C. Metaplasia
D. Hypertrophy
B. Apoptosis
RATIONALE: Apoptosis is programmed cell death that eliminates
damaged or unwanted cells without triggering an inflammatory response.
Necrosis (A) causes cell lysis and triggers inflammation. Metaplasia (C) is a
reversible change in cell type. Hypertrophy (D) is an increase in cell size.
5. Which type of cell adaptation occurs when the lining of the
esophagus changes from squamous to columnar cells due to chronic
acid reflux?
, A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
C. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one mature cell
type by another, often as a protective response to chronic irritation. Atrophy
(A) is a decrease in cell size. Hyperplasia (B) is an increase in cell number.
Dysplasia (D) is disordered growth.
6. The process whereby a stem cell undergoes cell division with an
average cycle time of 24 hours is called the:
A. Cell cycle
B. Mitosis phase
C. Interphase
D. Differentiation cascade
A. Cell cycle
RATIONALE: The cell cycle consists of interphase (G1, S, G2) and mitotic
phase (M), during which a stem cell replicates its DNA and divides into two
daughter cells. Mitosis (B) is only one phase. Interphase (C) is the preparatory
phase. Differentiation (D) is the process of specialization.
7. Anaphylaxis is classified as which type of hypersensitivity reaction?
A. Type I
B. Type II
C. Type III
D. Type IV
