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 Resolution Result Verified Answers and a detailed rationale
explaining the underlying pathophysiology.
Section 1Resolution Result Verified Answers 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
Resolution Result Verified Answers Resolution Result Verified Answers B)
Hypertrophy
RationaleResolution Result Verified Answers 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 asResolution Result
Verified Answers
A) Dysplasia
B) Hyperplasia
C) Metaplasia
D) Anaplasia
Resolution Result Verified Answers Resolution Result Verified Answers C)
Metaplasia
RationaleResolution Result Verified Answers 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
Resolution Result Verified Answers C) Breast enlargement during pregnancy
RationaleResolution Result Verified Answers 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
Resolution Result Verified Answers B) Coagulative necrosis
RationaleResolution Result Verified Answers 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
Resolution Result Verified Answers B) Brain infarction (stroke)
RationaleResolution Result Verified Answers 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
Resolution Result Verified Answers A) Tuberculosis
RationaleResolution Result Verified Answers 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 asResolution Result Verified Answers
A) Uncontrolled cell death causing inflammation
B) Programmed cell death (physiologic)
C) Necrosis due to ischemia
D) Cell death due to bacterial toxins
Resolution Result Verified Answers B) Programmed cell death
RationaleResolution Result Verified Answers 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?
