NURS 611 — ADVANCED PATHOPHYSIOLOGY PRACTICE
EXAM MARYVILLE UNIVERSITY — GRADUATE NURSING
PROGRAM 2026/2027 COMPLETE (100) CURRENT
TESTING QUESTIONS AND CORRECT ANSWERS WITH
DETAILED RATIONALES.
PATHOPHYSIOLOGY
Prepare for the NURS 611 Exam – Maryville University with a focused study resource
designed to reinforce advanced pathophysiology concepts and alterations in normal
body function. It supports review of pathophysiologic processes underlying human
disease across the lifespan, including cellular dysfunction, genetics, inflammation,
immune responses, fluid and electrolyte imbalances, and alterations affecting major
body systems. This resource is best suited for Maryville University NURS 611 students,
nurse practitioner learners, and graduate nursing students preparing for Advanced
Pathophysiology assessments.



MULTIPLE CHOICE.
SECTION 1: CELLULAR INJURY, ADAPTATION, AND DEATH (Questions 1–15)
Question 1:
What is the most common cause of cellular injury leading to necrosis,
particularly affecting the kidney and heart?
A) Free radical damage
B) Hypoxia
C) Genetic mutations
D) Bacterial toxins
Answer: B) Hypoxia
Rationale: Hypoxia is the number one major cause of cellular injury
leading to necrosis, especially in the kidney and heart. Hypoxia deprives
cells of oxygen, leading to ATP depletion, failure of the sodium-potassium
pump, and ultimately cell death. Free radicals (A), genetic mutations (C),
and bacterial toxins (D) can also cause cellular injury but are less
common causes of necrosis.

Question 2:
A patient with prolonged hypertension develops an increase in the size of
myocardial cells. This is an example of:
A) Hyperplasia
B) Metaplasia
C) Hypertrophy
D) Dysplasia
Answer: C) Hypertrophy
Rationale: Hypertrophy is an increase in the size of cells. Pathologic
hypertrophy occurs secondary to hypertension, as the myocardium works
against increased afterload. Hyperplasia (A) is an increase in the number
of cells; metaplasia (B) is the replacement of one cell type with another;
dysplasia (D) is abnormal cell growth and maturation.


Question 3:
A patient with chronic lung disease has normal columnar ciliated epithelial
cells of the bronchial lining replaced by stratified squamous epithelial cells.
This process is known as:
A) Hypertrophy
B) Hyperplasia
C) Metaplasia
D) Anaplasia
Answer: C) Metaplasia
Rationale: Metaplasia is the replacement of one differentiated cell type
with another. In chronic lung disease, the normal columnar ciliated
epithelium is replaced by stratified squamous epithelium as an adaptive
response to chronic irritation. Hypertrophy (A) is cell enlargement;
hyperplasia (B) is an increase in cell number; anaplasia (D) is the loss of
differentiation in cancer cells.

Question 4:
A patient has endometrial tissue growing outside the uterus. This is an
example of:
A) Pathologic hyperplasia
B) Compensatory hyperplasia
C) Physiologic hyperplasia
D) Dysplasia
Answer: A) Pathologic hyperplasia
Rationale: Pathologic hyperplasia is abnormal proliferation of cells in
response to excessive hormonal stimulation or growth
factors. Endometrial hyperplasia is a classic example of pathologic
hyperplasia. Compensatory hyperplasia (B) occurs when tissue
regenerates after injury (e.g., liver regeneration); physiologic hyperplasia
(C) occurs in normal processes like pregnancy; dysplasia (D) is abnormal
cell growth.


Question 5:
During ischemia, reduction in ATP levels causes which of the following
cellular events?
A) Intracellular accumulation of potassium and calcium
B) Intracellular accumulation of sodium and calcium
C) Extracellular accumulation of sodium
D) Decreased intracellular calcium
Answer: B) Intracellular accumulation of sodium and calcium
Rationale: Reduction in ATP levels causes the plasma membrane's
sodium-potassium pump and sodium-calcium exchange to fail, leading to
intracellular accumulation of sodium and calcium and diffusion of
potassium out of the cell. Sodium and water enter the cell freely, resulting
in cellular swelling. Option A incorrectly describes potassium
accumulation; C and D are not accurate.

Question 6:
What is necrosis?
A) Programmed cell death
B) Death of most or all cells in an organ or tissue due to disease, injury, or
failure of the blood supply
C) A protective inflammatory response
D) Cellular adaptation to stress
Answer: B) Death of most or all cells in an organ or tissue due to disease,
injury, or failure of the blood supply
Rationale: Necrosis is the death of most or all cells in an organ or tissue
due to disease, injury, or failure of the blood supply. Apoptosis (A) is
programmed cell death. Necrosis is characterized by rapid loss of plasma
membrane structure, organelle swelling, and mitochondrial dysfunction.


Question 7:
What is apoptosis?
A) Programmed cell death
B) Uncontrolled cell division
C) Cellular adaptation to stress
D) Inflammation
Answer: A) Programmed cell death
Rationale: Apoptosis is programmed cell death, a normal physiological
process that eliminates unwanted or damaged cells without causing
inflammation. This is in contrast to necrosis (B), which is unprogrammed
cell death due to injury.


Question 8:
Free radicals play a major role in the initiation and progression of which of the
following diseases? (Select all that apply)
A) Hyperlipidemia
B) Diabetes mellitus
