350 Exam Questions and Correct Answers | GCU NUR 631 Latest Exam Prep
INTRODUCTION
NUR 631 Advanced Physiology and Pathophysiology covers advanced concepts in cellular
adaptation, injury, inflammation, immune responses, fluid/electrolyte balance, acid-base
disorders, genetics, and system-specific pathophysiology across the lifespan . The course
emphasizes the etiology, pathogenesis, and clinical manifestations of disease processes . This
test bank contains 350 exam-style questions with verified answers and detailed rationales for
both midterm and final exam preparation.
SECTION 1: CELLULAR ADAPTATION, INJURY, AND DEATH (Questions 1-40)
Question 1: In response to chronic hypertension, the left ventricle of the heart may adapt
through which type of cellular change?
A) Hyperplasia
B) Atrophy
C) Hypertrophy
D) Metaplasia
Correct Answer: C
Rationale: Hypertrophy is an increase in cell size in response to increased workload or
functional demand. Chronic hypertension increases afterload on the left ventricle, causing
myocardial cells to increase in size (hypertrophy) to maintain cardiac output. Hyperplasia
involves an increase in cell number and occurs in tissues capable of mitosis, but not in cardiac
muscle. Atrophy is a decrease in cell size. Metaplasia is replacement of one cell type with
another.
Key Concept: Hypertrophy = increased cell size.
,Difficulty: Easy
Question 2: A patient who is a heavy smoker develops changes in the bronchial epithelium
from ciliated columnar to stratified squamous. This represents:
A) Dysplasia
B) Metaplasia
C) Neoplasia
D) Hypertrophy
Correct Answer: B
Rationale: Metaplasia is the reversible replacement of one differentiated cell type with another.
In response to chronic irritation (such as cigarette smoke), bronchial columnar epithelium
undergoes squamous metaplasia. This is an adaptive response but can be premalignant if the
irritant persists. Dysplasia is abnormal cellular growth and maturation. Neoplasia is new,
uncontrolled growth.
Hypertrophy is increased cell size.
Key Concept: Metaplasia = replacement of one cell type with another.
Difficulty: Easy
Question 3: The cellular process of "programmed cell death" is called:
A) Necrosis
B) Autolysis
C) Apoptosis
D) Coagulative necrosis
Correct Answer: C
Rationale: Apoptosis is a genetically programmed, energy-dependent form of cell death that
eliminates unwanted cells without triggering inflammation. It is essential for normal tissue
homeostasis and development. Necrosis is accidental, unprogrammed cell death caused by
injury and triggers inflammation. Autolysis is self-digestion by cellular enzymes. Coagulative
necrosis is a specific type of necrosis seen in ischemic injury.
, Key Concept: Apoptosis = programmed cell death.
Difficulty: Easy
Question 4: A patient with a myocardial infarction experiences cell death due to ischemia. The
type of necrosis most likely seen in the infarcted tissue is:
A) Liquefactive necrosis
B) Coagulative necrosis
C) Caseous necrosis
D) Fat necrosis
Correct Answer: B
Rationale: Coagulative necrosis is the most common type of necrosis and is seen in ischemic
injury (e.g., myocardial infarction). The tissue architecture is preserved initially due to
denaturation of cellular proteins. Liquefactive necrosis is seen in the brain and bacterial
infections. Caseous necrosis is seen in tuberculosis. Fat necrosis is seen in pancreatitis or breast
trauma.
Key Concept: Coagulative necrosis = ischemic injury.
Difficulty: Easy
Question 5: In a patient with severe protein-calorie malnutrition, which cellular adaptation is
most likely to occur?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Correct Answer: C
Rationale: Atrophy is a decrease in cell size and mass resulting from reduced workload,
decreased blood supply, inadequate nutrition, or loss of endocrine stimulation. In malnutrition,
cells decrease size to conserve energy and resources.
