Introduction
This comprehensive WGU D236 Pathophysiology Objective Assessment examination
is designed for Western Governors University students preparing for the 2026/2027
Pathophysiology objective assessment. The exam contains 150 multiple-choice
questions covering all essential pathophysiology concepts required for successful
completion of the D236 course. Questions address cellular injury and adaptation,
,inflammation and immune responses, fluid and electrolyte balance, acid-base
regulation, genetics and congenital disorders, and pathophysiology of all major body
systems including cardiovascular, pulmonary, renal, gastrointestinal, neurological,
musculoskeletal, and endocrine systems. Each question includes a detailed
rationale to reinforce understanding of disease processes and mechanisms. This
resource is verified for accuracy and reflects current WGU D236 curriculum
standards.
SECTION ONE: QUESTIONS 1 – 150
Question 1
Which cellular adaptation is characterized by a decrease in cell size and organ
volume?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
C
RATIONALE: Atrophy is the decrease or shrinkage in cellular size. If it occurs in a
sufficient number of cells, the entire organ shrinks or becomes atrophic.
Hypertrophy is an increase in cell size, hyperplasia is an increase in cell number, and
metaplasia is the replacement of one cell type with another.
Question 2
Programmed cell death is known as:
A. Necrosis
B. Apoptosis
,C. Autophagy
D. Pyroptosis
B
RATIONALE: Apoptosis is programmed cell death, a normal physiological
process that eliminates unwanted or damaged cells without causing inflammation.
Necrosis is unprogrammed cell death resulting from injury, autophagy is the
degradation of cellular components, and pyroptosis is a form of programmed cell
death associated with inflammation.
Question 3
A patient with long-standing uncontrolled hypertension develops an enlarged left
ventricle. This cellular adaptation is best described as:
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Dysplasia
B
RATIONALE: Hypertrophy is an increase in cell size that results in organ
enlargement. The left ventricle enlarges in response to increased workload from
hypertension. This is an adaptive mechanism to meet increased demands.
Question 4
Which of the following is a hallmark of irreversible cell injury and necrosis?
A. Cellular swelling
B. Nuclear dissolution (karyolysis)
C. Loss of microvilli
D. Ribosomal detachment
, B
RATIONALE: Nuclear dissolution (karyolysis) is a hallmark of irreversible injury
and necrosis. Other irreversible changes include nuclear pyknosis and karyorrhexis.
Cellular swelling, loss of microvilli, and ribosomal detachment are reversible
changes.
Question 5
Which cellular process involves the replacement of one differentiated cell type with
another?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
D
RATIONALE: Metaplasia is the reversible replacement of one differentiated cell
type with another. It represents an adaptive response to chronic irritation or
inflammation. Atrophy is decreased cell size, hypertrophy is increased cell size, and
hyperplasia is increased cell number.
Question 6
T cells produce which substances that stimulate B cells to produce antibodies?
A. Antigens
B. Cytokines
C. Histamines
D. Prostaglandins
B
