Core Domains
• Cellular Adaptation, Injury, and Death
• Genetics and Genetic Disorders
• Inflammation, Immunity, and Hypersensitivity
• Fluid, Electrolyte, and Acid-Base Balance
• Neurological Pathophysiology

Introduction
This examination assesses the nursing student's knowledge of
pathophysiology at Nightingale College. It evaluates understanding of
disease mechanisms, cellular alterations, and systemic responses to
injury and illness. Questions include multiple-choice and scenario-based
formats designed to test clinical judgment and decision-making.
Candidates must demonstrate competency in recognizing pathological
processes, analyzing clinical manifestations, and applying
pathophysiological principles to patient care. The exam emphasizes
real-world application and critical thinking across diverse disease
states.
,Section One: Questions 1–100
1. Pathophysiology is best defined as the study of:
A. The structural alterations in cells and tissues that identify disease
B. The underlying changes in body physiology that result from disease
or injury
C. The tracking of disease occurrence and transmission among
populations
D. The naming and identification of diseases based on signs and
symptoms
B. The underlying changes in body physiology that result from
disease or injury
RATIONALE: Pathophysiology focuses on the underlying changes
in body physiology at the molecular, cellular, and organ system levels
that result from disease or injury. Pathology investigates structural
alterations. Epidemiology tracks disease patterns. Diagnosis is the
naming of a disease .
2. A patient with chronic anemia develops an enlarged spleen. This
represents which type of cellular adaptation?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
B. Hypertrophy
RATIONALE: Hypertrophy is an increase in cell size. In chronic
anemia, the spleen works harder to remove damaged RBCs, causing its
reticuloendothelial cells to enlarge. Hyperplasia is increased cell
number; atrophy is shrinkage; metaplasia is one cell type replacing
another .
, 3. A client is diagnosed with Barrett's esophagus due to chronic acid
reflux. The pathology report shows that normal stratified squamous
epithelium has been replaced by columnar epithelium. This is an
example of:
A. Dysplasia
B. Neoplasia
C. Metaplasia
D. Anaplasia
C. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one
mature cell type by another mature cell type better suited to handle a
harsh environment. Barrett's esophagus is columnar metaplasia of
squamous esophageal epithelium due to acid reflux .
4. A patient with prolonged ischemia shows irreversible cell injury.
Which event most directly indicates irreversibility?
A. Decreased ATP
B. Sodium-potassium pump dysfunction
C. Mitochondrial swelling
D. Severe membrane damage with lysosomal rupture
D. Severe membrane damage with lysosomal rupture
RATIONALE: Irreversible injury is marked by severe membrane
damage (plasma, lysosomal, mitochondrial) leading to enzyme leakage
and cell death. Decreased ATP and pump dysfunction are reversible
initially .
5. During apoptosis, which feature distinguishes it from necrosis?
A. Cell swelling
B. Inflammation
C. Preservation of membrane integrity until engulfment
D. Random DNA fragmentation
, C. Preservation of membrane integrity until engulfment
RATIONALE: Apoptosis is programmed cell death without
inflammation. In apoptosis, the cell membrane remains intact until the
cell is engulfed by phagocytes, preventing an inflammatory response.
Necrosis causes cell swelling, membrane rupture, and inflammation .
6. Which cellular organelle is known as the "powerhouse of the cell"
and is the site of ATP production?
A. Nucleus
B. Ribosome
C. Mitochondria
D. Lysosome
C. Mitochondria
RATIONALE: Mitochondria are the powerhouse of the cell, the
organelle that is the site of ATP (energy) production. The nucleus
controls cell activities and carries genes. Ribosomes provide sites for
protein synthesis. Lysosomes contain enzymes for digesting cellular
substances .
7. What term is used to describe cancer that extends to organs or
tissues distant from the site of origin?
A. Anaplasia
B. Metastasis
C. Dysplasia
D. Neoplasia
B. Metastasis
RATIONALE: Metastasis describes cancer that has spread to distant
organs or tissues from the original site of origin. For metastasis to occur,
tumor cells must be capable of surviving in the bloodstream .
