NR507 Advanced Pathophysiology
Final Exam – Comprehensive Study
Guide with Verified Q&A
This comprehensive study guide is organized by topic area to help you prepare for the
NR507 Advanced Pathophysiology Final Exam at Chamberlain University. Each question
includes a verified answer and a detailed rationale explaining the underlying
pathophysiology.
Section 1: Cellular Adaptation & Injury (Questions 1–15)
Q1. A client with long-standing hypertension develops an enlarged left ventricle.
This is an example of which cellular adaptation?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: B) Hypertrophy
Rationale: Hypertrophy is an increase in cell size leading to organ enlargement. Cardiac
muscle cells cannot divide (hyperplasia), so they enlarge in response to increased
workload from hypertension. This is a compensatory mechanism to maintain cardiac
output against increased afterload .
,Q2. A client who smokes develops a change in the bronchial epithelium from
ciliated columnar to stratified squamous. This is known as:
A) Dysplasia
B) Hyperplasia
C) Metaplasia
D) Anaplasia
Answer: C) Metaplasia
Rationale: Metaplasia is the reversible replacement of one differentiated cell type with
another. This is an adaptive response to chronic irritation from cigarette smoke. While
initially protective, this change increases the risk of dysplasia and malignancy .
Q3. Which of the following is an example of physiologic hyperplasia?
A) Endometrial hyperplasia
B) Benign prostatic hyperplasia
C) Breast enlargement during pregnancy
D) Hyperplasia of the epidermis in psoriasis
: C) Breast enlargement during pregnancy
Rationale: Physiologic hyperplasia is a normal, controlled response to a specific
stimulus. Breast enlargement during pregnancy involves both hyperplasia (increased cell
number) and hypertrophy (increased cell size) to prepare for lactation. The other options
are pathologic hyperplasia .
,Q4. Which type of necrosis is characteristic of myocardial infarction?
A) Liquefactive necrosis
B) Coagulative necrosis
C) Caseous necrosis
D) Fat necrosis
: B) Coagulative necrosis
Rationale: Coagulative necrosis is characteristic of ischemic injury in solid organs such
as the heart, kidney, and liver. The architecture of dead tissue is preserved for several
days due to denaturation of structural proteins .
Q5. Liquefactive necrosis is characteristic of which organ injury?
A) Myocardial infarction
B) Brain infarction (stroke)
C) Tuberculosis
D) Ischemic injury to the kidney
: B) Brain infarction (stroke)
Rationale: Liquefactive necrosis occurs in the brain due to enzymatic digestion of
necrotic tissue, forming a cystic space. The brain has high lipid content and lacks
supporting stroma, leading to liquefaction .
Q6. Caseous necrosis is characteristic of which condition?
, A) Tuberculosis
B) Myocardial infarction
C) Pancreatitis
D) Gangrene
: A) Tuberculosis
Rationale: Caseous necrosis (cheese-like) is characteristic of tuberculosis, representing a
combination of coagulative and liquefactive necrosis with granulomatous inflammation.
The necrotic tissue appears white, friable, and cheesy .
Q7. Apoptosis is best described as:
A) Uncontrolled cell death causing inflammation
B) Programmed cell death (physiologic)
C) Necrosis due to ischemia
D) Cell death due to bacterial toxins
: B) Programmed cell death
Rationale: Apoptosis is programmed cell death that occurs in a controlled, orderly
manner without inflammation. It is important for development, tissue homeostasis, and
elimination of damaged cells. Necrosis is unprogrammed and causes inflammation .
Q8. A patient with a benign tumor is diagnosed. Which characteristic is expected?
A) Poorly differentiated cells
B) Metastasis to distant sites
