paid/locked exam questions, answer keys, or claim access to an actual examination.

, 1. Midterm Blueprint
The supplied Stuvia page is a 19-page 2025/2026 NURS 6501 midterm resource. Its public preview organizes material around cellular and
molecular pathophysiology and shows questions on hypoxic injury/ATP depletion, epigenetic silencing, apoptosis, hypertrophy, reactive
oxygen species, necrosis, protein-folding disorders and ion-channel disease. ■cite■turn0view0■
Walden describes Advanced Pathophysiology as a graduate course focused on normal organ-system function, deviations from normal
physiology, interrelated systems, homeostasis, and using pathophysiologic knowledge to develop appropriate treatment plans across the
lifespan. ■cite■turn0search2■
Public NURS 6501 study resources also identify recurring domains including cellular injury/adaptation, inflammation, genetics, immunology,
hematology, renal, pulmonary, cardiovascular, endocrine and gastrointestinal pathophysiology. ■cite■turn0search0■
Study priority What to master
Mechanisms Know the chain: trigger → molecular/cellular change → tissue effect → clinical manifestation.
Cell injury ATP depletion, membrane injury, calcium, ROS, apoptosis vs necrosis.
Genetics Mutation, inheritance, gene expression, epigenetics.
Inflammation/immunity Acute vs chronic inflammation, innate/adaptive immunity, hypersensitivity.
Systems Cardiac, pulmonary, renal, endocrine, GI and hematologic mechanisms.
2. Cellular Adaptation & Injury
Hypertrophy, hyperplasia, atrophy, metaplasia
Adaptation Core idea Classic example
Hypertrophy Increased cell size Cardiac myocyte enlargement with pressure overload
Hyperplasia Increased cell number Hormonal/endometrial proliferation
Atrophy Reduced cell size/function Disuse or reduced trophic stimulation
Metaplasia One mature cell type replaced by another Protective response to chronic irritation
A major exam distinction is hypertrophy = bigger cells whereas hyperplasia = more cells. Cardiac muscle responds primarily through
hypertrophy because mature cardiomyocytes have limited proliferative capacity.
Hypoxic injury
• Oxygen deprivation impairs mitochondrial oxidative phosphorylation.
• ATP falls, reducing Na■/K■-ATPase activity.
• Intracellular sodium and water rise → cellular swelling.
• Anaerobic glycolysis increases → lactate and intracellular acidosis.
• Persistent injury causes membrane, mitochondrial and nuclear damage and can progress to cell death.
The public preview specifically tests impaired mitochondrial electron transport as the primary event causing ATP depletion in hypoxia.

3. Reversible vs Irreversible Cell Injury
Feature Reversible injury Irreversible injury
ATP Reduced but recoverable Severe/persistent depletion
Cell swelling Common May progress to membrane rupture
Mitochondria Dysfunction Severe membrane damage
Membranes Initially intact Loss of integrity
Outcome Recovery if cause removed Necrosis/apoptosis depending on mechanism
Exam reasoning
When a question asks for the earliest consequence of hypoxia, think energy failure and ion-pump dysfunction before later structural
destruction. When it asks for irreversible injury, look for profound mitochondrial/membrane damage and inability to restore homeostasis.
