Introduction
This comprehensive study guide is designed to prepare students for the N212
Pathophysiology Exam 1 at Eastwick College. It covers all foundational content areas
tested on the examination, including introduction to pathophysiology, cellular
adaptation and injury, inflammation and tissue repair, immunity and immune
function, stress response, genetics and genetic disorders, cancer pathophysiology,
fluid and electrolyte balance, acid-base imbalances, and aging effects on body
systems. The questions are formatted to reflect the style and difficulty of actual exam
,questions, with an emphasis on clinical application and critical thinking. Each
question is followed by the correct answer and a detailed rationale to reinforce
understanding of key pathophysiologic concepts. This guide reflects the most current
2026 curriculum and is structured to help you achieve success on the examination.
SECTION ONE: QUESTIONS 1–70
Question 1
Which of the following best defines pathophysiology?
A. The study of the structure of the human body
B. The study of the function of the human body
C. The study of the biological and physical changes that occur in the body as a result
of disease
D. The study of the psychological aspects of disease
C. The study of the biological and physical changes that occur in the body as a
result of disease
RATIONALE: Pathophysiology is the study of the biological and physical changes
that occur in the body as a result of disease. It integrates pathology (the study of
structural changes) with physiology (the study of function) to explain disease
processes.
Question 2
A patient presents with a fever, elevated white blood cell count, and localized pain
and swelling at the site of a wound. These signs and symptoms indicate:
A. Cellular atrophy
B. Inflammation
C. Metaplasia
D. Neoplasia
B. Inflammation
, RATIONALE: The classic signs of inflammation are fever, leukocytosis (elevated
WBC count), and localized signs such as pain, swelling, redness, and heat. These are
the body's response to tissue injury or infection.
Question 3
When a cell adapts to an increased workload by increasing in size, this process is
called:
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
B. Hypertrophy
RATIONALE: Hypertrophy is an increase in cell size in response to increased
workload or demand. Hyperplasia is an increase in cell number. Metaplasia is the
replacement of one cell type with another. Dysplasia is abnormal cell growth.
Question 4
A 45-year-old man undergoes a biopsy of his left ventricle following a myocardial
infarction. The pathology report notes an increase in the size of individual cardiac
muscle cells without an increase in cell number. Which of the following best
describes this cellular adaptation?
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Dysplasia
C. Hypertrophy
RATIONALE: Cardiac muscle cells undergo hypertrophy (increase in size) in
response to increased workload, such as hypertension or myocardial infarction.
Cardiac muscle cells do not undergo hyperplasia (increase in number) because they
are terminally differentiated.
