INTRODUCTION
The NSG 3280 – Pathophysiology Midterm Exam evaluates a nursing student's ability to
connect cellular and physiologic mechanisms with the signs, symptoms, complications, and
clinical manifestations of disease. Rather than simply recalling definitions, students must
recognize how alterations in normal physiology produce specific patient findings and determine
which pathophysiologic process best explains a clinical presentation. Major areas commonly
encountered in a comprehensive pathophysiology midterm include cellular injury and adaptation,
inflammation, immune responses, fluid and electrolyte disturbances, acid-base balance,
hemodynamic disorders, infection, genetic mechanisms, neoplasia, cardiovascular disorders,
respiratory disorders, renal dysfunction, endocrine abnormalities, and neurologic disease.
This advanced question bank is designed for nursing students preparing for a challenging
midterm examination. The questions emphasize clinical reasoning, mechanism-based thinking,
interpretation of laboratory findings, prioritization, and application of physiologic principles to
patient scenarios. Each question contains four answer choices, one best answer, and a detailed
rationale explaining why the correct response is physiologically appropriate and why the
alternatives are less appropriate. Working through these questions helps students identify
knowledge gaps, strengthen clinical reasoning, and prepare to apply pathophysiology concepts
under examination conditions.

QUESTIONS 1-100
CELLULAR INJURY AND ADAPTATION
Q1: A patient experiences prolonged hypotension after major blood loss. Which cellular
change most directly occurs first when oxygen delivery becomes inadequate?
A) Increased oxidative phosphorylation
B) Decreased ATP production from impaired oxidative phosphorylation
C) Increased protein synthesis
D) Increased intracellular calcium sequestration
Rationale: B is correct because inadequate oxygen prevents mitochondria from maintaining
normal oxidative phosphorylation, causing ATP depletion. A is incorrect because oxidative
phosphorylation decreases rather than increases. C is incorrect because energy-dependent
protein synthesis becomes impaired. D is incorrect because ATP depletion disrupts calcium
pumps, causing intracellular calcium accumulation rather than enhanced sequestration.
Q2: A patient with severe ischemia develops irreversible myocardial injury. Which finding
most strongly indicates that cellular injury has progressed from reversible to irreversible?
A) Cellular swelling
B) Fatty change
C) Mitochondrial dysfunction with severe membrane damage
D) Glycogen depletion
Rationale: C is correct because severe mitochondrial and plasma-membrane damage represents
a critical point of irreversible injury. A, B, and D can occur during reversible cellular stress.
Cellular swelling and fatty change may resolve if the underlying insult is removed, while
glycogen depletion primarily reflects altered energy metabolism.
Q3: A patient has chronic gastric irritation causing replacement of normal epithelial cells
with a different mature epithelial type. Which adaptation is occurring?
A) Hypertrophy
B) Hyperplasia
C) Dysplasia
D) Metaplasia
, 4|P a g e
Rationale: D is correct because metaplasia is a reversible substitution of one differentiated adult
cell type for another better able to tolerate chronic stress. Hypertrophy increases cell size,
hyperplasia increases cell number, and dysplasia involves disordered cellular growth and
atypia.
Q4: A patient with long-standing hypertension develops increased left ventricular wall
thickness. Which mechanism best explains this change?
A) Increased cardiomyocyte number
B) Cellular necrosis
C) Increased cardiomyocyte size caused by chronic workload
D) Replacement of myocardium with adipose tissue
Rationale: C is correct because cardiac muscle responds to chronic pressure overload primarily
through hypertrophy, increasing individual cell size. A is incorrect because mature cardiac
myocytes have limited proliferative capacity. B represents injury rather than adaptation. D is not
the normal mechanism responsible for pressure-induced ventricular hypertrophy.
Q5: A laboratory investigation shows DNA fragmentation and controlled removal of
individual cells without surrounding inflammation. Which process is occurring?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Autolysis
D) Apoptosis
Rationale: D is correct because apoptosis is programmed cell death characterized by cellular
fragmentation and removal without significant inflammatory response. Necrosis generally
involves uncontrolled cell injury and inflammation. Autolysis refers to enzymatic cellular
breakdown and does not describe the regulated process presented.
Q6: A patient develops tissue ischemia after an arterial embolus. Why does ATP depletion
cause cellular swelling?
A) Increased sodium-potassium pump activity
B) Increased plasma oncotic pressure
C) Failure of ATP-dependent ion pumps causing intracellular sodium and water accumulation
D) Increased intracellular protein synthesis
Rationale: C is correct because ATP depletion impairs the Na+/K+ ATPase, allowing sodium to
accumulate intracellularly and water to follow osmotically. A is the opposite of what occurs. B
concerns extracellular fluid forces rather than the primary cellular mechanism. D requires ATP
and therefore decreases during severe energy depletion.
