MSN 570 Advanced Pathophysiology
Original Exam Mastery 2026/2027
100 Original Graduate-Level Practice Questions • Answers • Rationales • Rapid Review •
Clinical Reasoning
This independently authored study resource is designed for advanced nursing pathophysiology review. It is based
on publicly visible topic information associated with MSN 570 and on standard, authoritative pathophysiology
concepts. It is not an official United States University examination, does not contain actual exam questions, and
does not reproduce the paid Stuvia resource.
How to use this guide
• Attempt each question before looking at the answer.
• Use the rationale to identify the mechanism, not merely memorize the letter choice.
• For difficult items, explain the pathophysiologic chain from trigger → mechanism → physiologic change →
manifestation.
• Revisit the Rapid Review section after completing the 100 questions.

,Scope & Topic Map
The requested Stuvia listing is a paid 48-page resource labeled as a 70-question 2026/2027 MSN 570 Advanced
Pathophysiology final. Its public preview identifies major areas including cellular injury/adaptation, inflammation and
immunity, genetics, neoplasia, hematology, cardiovascular/pulmonary, renal/fluid-electrolyte, endocrine/metabolic,
neurologic/musculoskeletal, and gastrointestinal/hepatic pathophysiology. This guide expands those public topic
signals into a broader, original 100-question review set.

,1. Cellular Adaptation, Injury & Death
Focus: adaptation versus injury, ATP depletion, membrane damage, oxidative stress, necrosis patterns, and programmed cell death.
1. A patient with chronic hypertension develops an enlarged left ventricular wall. Which cellular
adaptation best explains the change?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Answer: B
Rationale: Cardiac myocytes have limited proliferative capacity, so chronic pressure overload primarily increases cell
size. Hypertrophy increases contractile capacity but can eventually contribute to diastolic dysfunction and myocardial
oxygen demand.
2. A renal tubular cell exposed to transient ischemia develops cellular swelling but recovers after
perfusion is restored. Which finding is most consistent with reversible injury?
A. Membrane rupture
B. Severe mitochondrial failure
C. Cellular swelling from ATP depletion
D. Extensive nuclear fragmentation
Answer: C
Rationale: Early hypoxic injury reduces ATP production and impairs ion pumps, causing sodium and water accumulation.
If the insult is removed before critical membrane and mitochondrial damage occurs, the cell can recover.
3. Which mechanism most directly causes cellular swelling during early hypoxic injury?
A. Increased Na+/K+-ATPase activity
B. Failure of ATP-dependent ion pumps
C. Increased protein synthesis
D. Accelerated DNA replication
Answer: B
Rationale: ATP depletion impairs the Na+/K+-ATPase, allowing intracellular sodium to rise. Water follows osmotically,
producing hydropic or cellular swelling.

, 4. Which feature most strongly distinguishes apoptosis from classic necrosis?
A. Cell swelling
B. Plasma membrane rupture
C. Caspase-mediated programmed cell death
D. Marked local inflammation
Answer: C
Rationale: Apoptosis is a regulated form of cell death involving caspases, cellular shrinkage, chromatin condensation,
and membrane-bound apoptotic bodies. Classic necrosis commonly involves membrane rupture and inflammation.
5. A patient with a long-standing obstructive lung process develops replacement of one mature epithelial
phenotype by another better suited to chronic irritation. What process is this?
A. Atrophy
B. Metaplasia
C. Hypertrophy
D. Anaplasia
Answer: B
Rationale: Metaplasia is a reversible adaptive change in which one differentiated cell type is replaced by another.
Persistent injury can make the altered tissue more vulnerable to dysplasia and malignancy.
6. Which type of necrosis is classically associated with ischemic injury to most solid organs?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
Answer: A
Rationale: Coagulative necrosis generally preserves tissue architecture for a period after cell death and is typical of
ischemic injury in solid organs, with the brain being a major exception.
7. An area of cerebral infarction becomes soft and liquefied. Which pattern of necrosis is expected?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fibrinoid
Answer: B
Rationale: Brain tissue is particularly prone to liquefactive necrosis after ischemia. Hydrolytic enzymes digest the dead
tissue, producing a softened or liquid appearance.
