Introduction
This comprehensive examination is designed to assess the nursing
student's competency in pathophysiology, a foundational course for
clinical practice at Western Governors University. It evaluates the
understanding of disease processes, cellular mechanisms, and systemic
alterations that underlie common health conditions across the lifespan. The
exam utilizes a multiple-choice format with scenario-based questions that
reflect real-world clinical situations and align with Next Generation NCLEX
,(NGN) standards. Emphasis is placed on the application of
pathophysiological concepts to clinical reasoning, identification of risk
factors, and anticipation of complications. This assessment serves as a
predictor of success on the WGU D236 Objective Assessment (OA) and
helps identify areas for focused review. The questions are organized by
body system and pathophysiological process, covering cellular adaptation,
inflammation, fluid and electrolyte balance, acid-base disorders, genetic
factors, and major system disorders including cardiovascular, respiratory,
renal, endocrine, neurological, gastrointestinal, and hematologic
conditions. This resource is updated for the 2026/2027 academic year and
aligns with the latest WGU D236 course competencies.
SECTION ONE: QUESTIONS 1 - 100
1. A patient's muscle cells have decreased in size due to prolonged
immobilization. This cellular adaptation is known as:
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
C. Atrophy
RATIONALE: Atrophy is the decrease or shrinkage in cellular size,
often occurring due to disuse, denervation, ischemia, or decreased
blood flow. Prolonged immobilization leads to disuse atrophy of muscle
cells. Hypertrophy is an increase in cell size, hyperplasia is an increase
in cell number, and metaplasia is the replacement of one mature cell
type by another.
2. Which type of cellular adaptation involves an increase in the
number of cells resulting from an increased rate of cellular
division?
A. Neoplasia
B. Dysplasia
,C. Hypertrophy
D. Hyperplasia
D. Hyperplasia
RATIONALE: Hyperplasia is an increase in the number of cells in an
organ or tissue, which may be compensatory (e.g., liver regeneration)
or hormonal (e.g., endometrial hyperplasia). Neoplasia is uncontrolled
growth, dysplasia is abnormal cell changes, and hypertrophy is an
increase in cell size.
3. The replacement of one mature cell type by another, sometimes
less differentiated, cell type is called:
A. Dysplasia
B. Anaplasia
C. Metaplasia
D. Hyperplasia
C. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one mature
cell type by another, often as a response to chronic irritation. An
example is the replacement of ciliated columnar epithelium with
squamous epithelium in the respiratory tract of chronic smokers.
Dysplasia involves abnormal changes in cell size and shape.
4. Abnormal changes in the size, shape, and organization of mature
cells, often considered a precursor to cancer, is:
A. Metaplasia
B. Atrophy
C. Dysplasia
D. Hypertrophy
C. Dysplasia
RATIONALE: Dysplasia refers to abnormal changes in the size,
shape, and organization of mature cells. It is often considered a
, precursor to cancer (e.g., cervical dysplasia). Metaplasia and atrophy
are not precursors to cancer, and hypertrophy is an increase in cell size.
5. A client with cellular injury is found to have increased
intracellular calcium. This finding is most consistent with:
A. Cellular necrosis
B. Apoptosis
C. Cellular adaptation
D. Cellular regeneration
A. Cellular necrosis
RATIONALE: Increased intracellular calcium is a hallmark of cellular
necrosis. Calcium overload activates proteases and phospholipases,
leading to cell membrane destruction and further injury. Apoptosis is
programmed cell death that does not involve significant calcium influx
or inflammation.
6. Which process is characterized by programmed cell death
without triggering an inflammatory response?
A. Necrosis
B. Apoptosis
C. Coagulative necrosis
D. Caseous necrosis
B. Apoptosis
RATIONALE: Apoptosis is a controlled, energy-dependent process of
programmed cell death that does not trigger inflammation. Necrosis is
unregulated cell death that releases cellular contents and triggers an
inflammatory response. Coagulative and caseous necrosis are types of
necrosis.
7. The nurse notes that a client's wound has granulation tissue
forming. This indicates:
A. The wound is in the inflammatory phase
B. The wound is in the proliferative phase
