INTRODUCTION
This comprehensive NUR2063 Essentials of Pathophysiology practice examination
reviews foundational and advanced mechanisms underlying disease processes, cellular
injury, inflammation, fluid and electrolyte disturbances, cardiovascular dysfunction,
respiratory disorders, renal disease, endocrine abnormalities, neurologic conditions,
and gastrointestinal pathology. It is designed for Rasmussen University nursing
students preparing for Exams 1, 2, and 3 and seeking application-level mastery rather
than simple memorization. The questions emphasize clinical reasoning, interpretation
of pathophysiologic mechanisms, prioritization, and connections between disease
processes and manifestations. This resource contains 100+ questions and answers with
rationales for intensive preparation. Purchase and instantly get a downloadable and
editable pdf for convenient study and review.
QUESTIONS 1–30
Question 1
A patient experiences prolonged tissue hypoperfusion following severe hemorrhage.
Laboratory testing demonstrates elevated serum lactate and metabolic acidosis. Which
cellular mechanism most directly explains the initial increase in lactate?
A. Increased mitochondrial oxidative phosphorylation
B. Conversion of pyruvate to lactate because oxidative phosphorylation is impaired
,C. Increased beta-oxidation producing excess acetyl-CoA
D. Increased activity of the citric acid cycle
Correct Answer: B. Conversion of pyruvate to lactate because oxidative
phosphorylation is impaired
Rationale: Tissue hypoperfusion reduces oxygen delivery to mitochondria, limiting
oxidative phosphorylation. Cells compensate by relying more heavily on anaerobic
glycolysis, converting pyruvate to lactate and contributing to metabolic acidosis.
Question 2
A patient with prolonged hypertension develops left ventricular hypertrophy. Which
cellular adaptation best explains the increased myocardial wall thickness?
A. Hyperplasia caused by increased cardiomyocyte proliferation
B. Atrophy caused by reduced myocardial workload
C. Hypertrophy caused by increased workload and protein synthesis
D. Metaplasia caused by replacement of cardiac muscle with connective tissue
Correct Answer: C. Hypertrophy caused by increased workload and protein synthesis
Rationale: Cardiac myocytes have limited proliferative capacity. Chronic pressure
overload therefore produces hypertrophy, characterized primarily by increased cell size
and synthesis of structural proteins.
Question 3
A patient with chronic gastroesophageal reflux develops replacement of normal distal
esophageal squamous epithelium with columnar epithelium containing goblet cells.
Which process has occurred?
A. Dysplasia
B. Metaplasia
C. Hyperplasia
D. Hypertrophy
Correct Answer: B. Metaplasia
Rationale: Metaplasia is a reversible adaptive change in which one differentiated cell type
is replaced by another better able to tolerate persistent environmental stress. Barrett
esophagus is a classic example.
Question 4
,A patient receiving chemotherapy develops extensive cellular injury. Microscopic
examination demonstrates cell shrinkage, chromatin condensation, nuclear
fragmentation, and formation of apoptotic bodies without substantial surrounding
inflammation. Which mechanism is most consistent with these findings?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Apoptosis
D. Gangrenous necrosis
Correct Answer: C. Apoptosis
Rationale: Apoptosis is regulated cell death characterized by cell shrinkage, chromatin
condensation, nuclear fragmentation, and apoptotic bodies. Cellular contents are
generally contained, limiting inflammation.
Question 5
A patient sustains an ischemic injury to the myocardium. Which consequence of ATP
depletion most directly contributes to cellular swelling?
A. Increased intracellular sodium from failure of the sodium-potassium pump
B. Increased protein synthesis
C. Increased mitochondrial ATP production
D. Decreased intracellular water movement
Correct Answer: A. Increased intracellular sodium from failure of the sodium-
potassium pump
Rationale: ATP depletion impairs the Na⁺/K⁺-ATPase. Sodium accumulates intracellularly,
followed osmotically by water, producing cellular swelling.
Question 6
A patient develops acute inflammation after bacterial invasion of a wound. Which event
occurs earliest in the leukocyte recruitment sequence after endothelial activation?
A. Phagocytosis
B. Firm adhesion
C. Margination and rolling
D. Transmigration into the interstitial tissue
Correct Answer: C. Margination and rolling
Rationale: Leukocytes initially move toward the vessel wall and interact transiently with
, activated endothelium through selectins, producing rolling. Firm adhesion and
transmigration occur subsequently.
Question 7
A patient develops fever and systemic manifestations during a bacterial infection.
Which mediator is most directly associated with hypothalamic elevation of the
temperature set point?
A. Histamine
B. Prostaglandin E2
C. Bradykinin
D. Nitric oxide
Correct Answer: B. Prostaglandin E2
Rationale: Proinflammatory cytokines such as IL-1 and TNF stimulate prostaglandin E2
production in the hypothalamus, increasing the thermoregulatory set point and
producing fever.
Question 8
A patient with a severe bacterial infection develops disseminated activation of
coagulation and simultaneous bleeding from venipuncture sites. Which
pathophysiologic process best explains this presentation?
A. Isolated thrombocytopenia without coagulation activation
B. Systemic activation of coagulation causing consumption of platelets and clotting
factors
C. Increased synthesis of circulating anticoagulants
D. Localized endothelial vasoconstriction
Correct Answer: B. Systemic activation of coagulation causing consumption of
platelets and clotting factors
Rationale: Disseminated intravascular coagulation involves widespread coagulation
activation, microvascular thrombosis, and consumption of platelets and coagulation
factors, potentially producing simultaneous thrombosis and bleeding.
Question 9
A patient develops generalized edema after severe protein malnutrition. Which
alteration most directly promotes movement of fluid from the intravascular space into
the interstitial compartment?
