NSG5140 WEEK 5 MIDTERM EXAM —
ADVANCED PATHOPHYSIOLOGY
ORIGINAL ADVANCED PRACTICE QUESTIONS 1–100
WITH DETAILED RATIONALES — 2026/2027
INTRODUCTION
NSG 5140 Advanced Pathophysiology focuses on the mechanisms through which disease
disrupts normal cellular, tissue, and organ function and how the body attempts to maintain
homeostasis. The course requires students to move beyond memorization by integrating
physiological mechanisms with clinical manifestations, laboratory findings, and complex patient
presentations. South College describes Advanced Pathophysiology as an integrative science
emphasizing analysis of physiological states and problem-solving across multiple physiological
disciplines.
This practice question bank is designed for graduate-level nursing students preparing for a Week
5 midterm. The questions emphasize application, clinical reasoning, mechanism-based
interpretation, and distinguishing closely related pathophysiological processes. Each item
contains four answer choices with one best answer followed by a detailed rationale explaining
the reasoning behind the answer and why the alternatives are less appropriate.
Use the questions actively: identify the underlying mechanism before looking at the answer,
explain the clinical findings in your own words, and revisit questions you miss. This approach
can strengthen understanding of advanced pathophysiology rather than relying solely on
memorization.

QUESTIONS 1–100
SECTION 1 — CELLULAR ADAPTATION, INJURY &
DEATH
Q1:
A 72-year-old patient develops an acute arterial occlusion of the lower extremity. Within
minutes, the affected tissue becomes pale and painful. Which intracellular event is most directly
responsible for the earliest reversible cellular injury?
A) Increased DNA fragmentation
B) Decreased ATP production with failure of ATP-dependent ion pumps
C) Extensive lysosomal rupture
D) Irreversible mitochondrial membrane destruction
Rationale: The correct answer is B because acute ischemia reduces oxygen delivery, impairing
oxidative phosphorylation and ATP generation. ATP depletion compromises the Na⁺/K⁺-ATPase,
causing intracellular sodium and water accumulation and cellular swelling. A is more
characteristic of apoptosis. C and D are associated with more advanced, potentially irreversible
cellular injury.
Q2:
A patient experiences myocardial ischemia followed by restoration of coronary blood flow.
Despite restoration of oxygen delivery, additional myocardial damage develops. Which
mechanism best explains this finding?
A) Continued absence of oxygen
B) Reactive oxygen species generated during reperfusion
C) Complete inhibition of inflammatory signaling
D) Reduced intracellular calcium concentration
,3|Page
Rationale: The correct answer is B because reperfusion can generate reactive oxygen species
that damage lipids, proteins, and DNA. A does not explain injury after blood flow has returned.
C is incorrect because inflammation may increase during reperfusion. D is incorrect because
intracellular calcium overload can contribute to reperfusion injury.
Q3:
A patient with severe hypoxia develops progressive mitochondrial dysfunction. Which
consequence most directly contributes to irreversible cellular injury?
A) Increased glycogen synthesis
B) Increased protein synthesis
C) Loss of mitochondrial ability to maintain ATP production
D) Increased cellular differentiation
Rationale: The correct answer is C because severe mitochondrial dysfunction prevents adequate
ATP production and can promote membrane permeability, calcium dysregulation, and cell
death. A and B require adequate cellular energy. D represents an adaptive developmental
process rather than irreversible injury.
Q4:
A biopsy demonstrates cell shrinkage, chromatin condensation, nuclear fragmentation, and
formation of membrane-bound apoptotic bodies without significant surrounding inflammation.
Which process is occurring?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Apoptosis
D) Fat necrosis
Rationale: The correct answer is C. Apoptosis is programmed cell death characterized by
cellular shrinkage, chromatin condensation, DNA fragmentation, and apoptotic bodies. Necrosis
generally involves cell swelling, membrane disruption, and inflammatory response.
Q5:
A patient develops a cerebral infarction after prolonged interruption of cerebral blood flow.
Which type of necrosis is most characteristic of the affected brain tissue?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Fat necrosis
, 4|Page
Rationale: The correct answer is B because ischemic injury to the brain characteristically
produces liquefactive necrosis through enzymatic digestion of dead tissue. Coagulative necrosis
is typical of ischemic injury in most solid organs other than the brain. Caseous necrosis is
associated with certain granulomatous infections, while fat necrosis occurs in adipose tissue.
Q6:
A patient develops ventricular hypertrophy in response to longstanding hypertension. Which
cellular adaptation primarily accounts for the increased myocardial mass?
A) Hyperplasia
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Rationale: The correct answer is B. Cardiac myocytes have limited proliferative capacity, so
chronic pressure overload primarily causes enlargement of existing cells. Hyperplasia involves
increased cell number. Metaplasia involves replacement by another differentiated cell type,
while dysplasia refers to disordered cellular growth.
Q7:
A chronic smoker develops replacement of normal ciliated bronchial columnar epithelium with
stratified squamous epithelium. Which process is occurring?
A) Hypertrophy
B) Hyperplasia
C) Metaplasia
D) Anaplasia
Rationale: The correct answer is C. Metaplasia is a reversible adaptation in which one mature
cell type is replaced by another better able to tolerate chronic stress. It can increase
vulnerability to malignant transformation. Hypertrophy changes cell size, whereas hyperplasia
changes cell number.
Q8:
A patient with prolonged malnutrition develops significant reduction in skeletal muscle mass.
Which adaptation best describes this finding?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
