NR 507 Advanced Pathophysiology –
Comprehensive Practice Exam
EXAM OVERVIEW
NR 507 Advanced Pathophysiology is a foundational course in graduate
nursing programs that builds upon basic anatomy, physiology, and
microbiology to provide the scientific basis for advanced practice nursing .
The course covers common pathophysiological mechanisms, disease
detection, and physiological changes across the lifespan . Key content
areas include cellular adaptation and injury, fluid and electrolyte balance,
acid-base disorders, immunology, genetics, and multi-system
pathophysiology .
SECTION 1: Cellular Adaptation, Injury & Death (Questions 1-15)
Q1. What can Reactive Oxygen Species (ROS) cause at the cellular
level?
• A) Increased protein synthesis and enhanced mitochondrial function
• B) Lipid peroxidation, protein damage, and DNA fragmentation
• C) Enhanced cellular antioxidant production
• D) Increased ATP production
Answer: B – Reactive oxygen species cause cellular injury through lipid
peroxidation of membranes, damage to proteins (including enzymes), and
fragmentation of DNA. These effects are implicated in the pathogenesis of
heart disease, Alzheimer's disease, Parkinson's disease, and other chronic
conditions .
Q2. What is the body's primary defense against Reactive Oxygen
Species?
, • A) Increased ATP production
• B) Antioxidants (Vitamin E, Vitamin C, cysteine, glutathione, albumin,
ceruloplasmin, transferrin)
• C) Enhanced cellular respiration
• D) Increased protein synthesis
Answer: B – Antioxidants are the body's primary defense against ROS. They
neutralize free radicals by donating electrons without becoming
destabilized themselves. Key antioxidants include Vitamin E, Vitamin C,
cysteine, glutathione, albumin, ceruloplasmin, and transferrin .
Q3. Which of the following best describes hypertrophy?
• A) Increase in cell number
• B) Increase in cell size
• C) Decrease in cell size
• D) Conversion of one cell type to another
Answer: B – Hypertrophy is an increase in cell size, not number (which is
hyperplasia). It is caused by hormonal stimulation or increased functional
demand. Myocardial cells are permanent cells and cannot undergo
mitosis, so they adapt via hypertrophy .
Q4. A 62-year-old male with a 30-year history of poorly controlled
hypertension shows echocardiographic evidence of left ventricular
wall thickening. What is the primary cellular mechanism driving this
change?
• A) Hyperplasia due to increased mitotic division
• B) Hypertrophy due to increased protein synthesis
• C) Metaplasia due to chronic mechanical stress
• D) Dysplasia due to genetic mutations in myocytes
,Answer: B – Myocardial cells are permanent cells and cannot undergo
mitosis. When faced with a chronic increase in afterload (hypertension),
the myocytes adapt via hypertrophy, which involves an increase in cell size
driven by enhanced protein synthesis and the addition of sarcomeres .
Q5. Which cellular adaptation occurs when chronic irritation causes
replacement of one cell type with another?
• A) Atrophy
• B) Hypertrophy
• C) Hyperplasia
• D) Metaplasia
Answer: D – Metaplasia is a reversible change where one differentiated cell
type is replaced by another, often due to chronic irritation. An example is
Barrett's esophagus, where chronic acid exposure causes squamous
epithelium to be replaced by columnar epithelium .
Q6. A patient with chronic hypoxia develops increased production of
red blood cells. This is an example of:
• A) Physiologic hyperplasia
• B) Pathologic hyperplasia
• C) Compensatory hyperplasia
• D) Hormonal hyperplasia
Answer: C – Compensatory hyperplasia occurs when the body increases
cell production to compensate for a deficiency. In chronic hypoxia, the
kidneys release erythropoietin, which stimulates the bone marrow to
produce more red blood cells to increase oxygen-carrying capacity .
, Q7. Which type of cell death is characterized by cellular swelling,
rupture of the cell membrane, and an inflammatory response?
• A) Apoptosis
• B) Necrosis
• C) Autophagy
• D) Atrophy
Answer: B – Necrosis is a form of cell death characterized by cellular
swelling, rupture of the cell membrane, and leakage of cellular contents,
which triggers an inflammatory response. Apoptosis is programmed cell
death that does not elicit inflammation .
Q8. Which of the following best describes apoptosis?
• A) Programmed cell death without inflammation
• B) Necrosis with inflammation
• C) Cellular swelling and lysis
• D) Rapid tissue ischemia
Answer: A – Apoptosis is programmed cell death that occurs normally to
maintain tissue homeostasis and eliminate damaged or unnecessary cells.
It does not trigger an inflammatory response because cellular contents are
contained within apoptotic bodies that are phagocytosed .
Q9. Which type of necrosis is typically seen in myocardial infarction?
• A) Liquefactive necrosis
• B) Caseous necrosis
• C) Coagulative necrosis
• D) Fat necrosis
