ADVANCED PATHOPHYSIOLOGY
EXPANDED MIDTERM STUDY GUIDE — PREMIUM
REVIEW EDITION
200+ original Questions & Answers • Rationales • Clinical application • Exam traps • Memory cues
Independent educational resource: Newly authored from pathophysiology principles and the publicly visible topic areas of the supplied
Stuvia listing. It does not reproduce locked/premium text, does not claim to contain actual examination questions, and is not affiliated with
Chamberlain University.
Study method
• Answer before reading the explanation.
• For every disease, learn cause → mechanism → manifestations → complications.
• For multiple-choice vignettes, identify the physiologic system first, then the disrupted mechanism.
• Use the memory cues only after understanding the underlying mechanism.

, SECTION I — CELLULAR INJURY, ADAPTATION & NEOPLASIA
1. QUESTION What is cellular hypertrophy?
Answer: An increase in individual cell size that produces enlargement of a tissue or organ.
Rationale / Exam Note: It commonly occurs when cells cannot readily divide, such as cardiac myocytes responding to chronic
workload.
2. QUESTION What is cellular hyperplasia?
Answer: An increase in the number of cells within a tissue.
Rationale / Exam Note: Hyperplasia may be physiologic or pathologic and is distinct from hypertrophy.
3. QUESTION What is metaplasia?
Answer: A reversible change in which one differentiated adult cell type is replaced by another cell type better able to
tolerate a persistent stress.
Rationale / Exam Note: Metaplasia can be protective but may create a setting in which dysplasia and malignancy develop if the
injurious stimulus persists.
4. QUESTION What is dysplasia?
Answer: Disordered cellular growth and maturation characterized by abnormal cell size, shape, organization, and nuclear
features.
Rationale / Exam Note: Dysplasia is not synonymous with cancer, but severe dysplasia can be a precursor to invasive
malignancy.
5. QUESTION What is anaplasia?
Answer: A loss of cellular differentiation and organization characteristic of many malignant tumors.
Rationale / Exam Note: Anaplastic cells often show marked pleomorphism, abnormal nuclei, and disorganized architecture.
6. QUESTION What is apoptosis?
Answer: Programmed, regulated cell death that removes unwanted or damaged cells without the same inflammatory
response typical of necrosis.
Rationale / Exam Note: It is a normal homeostatic process and can also be triggered by cellular injury.
7. QUESTION How does necrosis differ from apoptosis?
Answer: Necrosis is uncontrolled cell death associated with membrane disruption and inflammation; apoptosis is regulated
cell death with orderly cellular fragmentation.
Rationale / Exam Note: The distinction is frequently tested in questions about tissue injury.
8. QUESTION What are caretaker genes?
Answer: Genes involved in maintaining genomic stability, including DNA repair and chromosome integrity.
Rationale / Exam Note: Loss of caretaker function can allow mutations to accumulate and contribute to cancer development.
9. QUESTION What are tumor-suppressor genes?
Answer: Genes that normally restrain cell proliferation, promote DNA repair, or trigger apoptosis when appropriate.
Rationale / Exam Note: Loss of tumor-suppressor activity removes important brakes on abnormal growth.
10. QUESTION What is cancer staging?
Answer: Staging describes the anatomic extent of a malignancy, including primary tumor characteristics and spread to
lymph nodes or distant sites.
Rationale / Exam Note: Staging helps determine prognosis and treatment strategy.
11. QUESTION What is cancer grading?
Answer: Grading describes how abnormal tumor cells look microscopically and how closely they resemble their tissue of
origin.
Rationale / Exam Note: Grade and stage are different concepts: grade reflects differentiation; stage reflects extent.
