University Study Guide
DOCUMENT OVERVIEW
• This study guide contains comprehensive multiple-choice practice questions
designed to assess mastery of advanced pathophysiology concepts across all major
body systems and disease processes covered in the NR 507 course.
• Use this material to identify knowledge gaps, reinforce learning through active
recall, review detailed rationales to deepen understanding, and build confidence for
high-stakes clinical decision-making in advanced practice nursing.
SECTION 1: CELLULAR ADAPTATION & INJURY (Questions 1-20)
1. A 65-year-old patient with chronic hypertension presents with left
ventricular hypertrophy on echocardiography. Which type of cellular
adaptation is occurring in the myocardium?
A) Atrophy
B) Hyperplasia
C) Dysplasia
D) Metaplasia
E) Hypertrophy
CORRECT ANSWER: E) Hypertrophy
,RATIONALE: Hypertrophy is an increase in cell size in response to increased
workload or demand. In chronic hypertension, the left ventricle responds to
sustained pressure overload by increasing the size of individual cardiac myocytes,
resulting in left ventricular hypertrophy. This is a compensatory mechanism to
maintain cardiac output against increased resistance. Atrophy would be a decrease
in size, hyperplasia would be an increase in cell number, dysplasia would be
abnormal development, and metaplasia would be conversion to a different cell
type—none of which apply to this scenario.
2. A 52-year-old smoker develops Barrett's esophagus, characterized by
replacement of normal stratified squamous epithelium with columnar
epithelium. This is an example of which cellular adaptation?
A) Anaplasia
B) Metaplasia
C) Hypertrophy
D) Aplasia
E) Necrosis
CORRECT ANSWER: B) Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one differentiated cell
type with another differentiated cell type. Barrett's esophagus represents chronic
irritation from gastric reflux causing the normal squamous epithelium to be
replaced with gastric-type columnar epithelium. This adaptation occurs as the
tissue attempts to protect itself from repeated injury. While potentially reversible in
early stages, prolonged metaplasia increases cancer risk. Anaplasia involves loss of
differentiation, and necrosis is cell death—neither applies here.
3. A 45-year-old woman with systemic lupus erythematosus develops
glomerulonephritis with proteinuria. Histologically, immune complex
deposition is noted. Which mechanism of cellular injury is primarily involved?
,A) Hypoxic injury
B) Immunologic injury
C) Chemical injury
D) Radiation injury
E) Infectious injury
CORRECT ANSWER: B) Immunologic injury
RATIONALE: Immunologic injury occurs when the immune system attacks the
body's own tissues, either through antibody-mediated mechanisms or cell-
mediated responses. In SLE-associated glomerulonephritis, immune complexes
deposit in the glomerular basement membrane, activating complement and
causing inflammation and tissue damage. This autoimmune mechanism is
characteristic of immunologic injury. The other options involve different injury
mechanisms not applicable to autoimmune disease pathogenesis.
4. A patient with advanced cirrhosis develops hepatic encephalopathy
secondary to elevated ammonia levels. Which mechanism best explains the
neurological symptoms?
A) Hypoxic injury
B) Chemical injury
C) Apoptosis
D) Necrosis
E) Coagulation necrosis
CORRECT ANSWER: B) Chemical injury
RATIONALE: Chemical injury occurs when toxic substances damage cellular
structures and function. Ammonia is a hepatic metabolite that should be converted
to urea but accumulates in cirrhosis, causing chemical toxicity to neurons.
Ammonia interferes with glutamate metabolism, inhibits ATP production, and
causes astrocyte swelling. While chemical injury can eventually lead to cell death
, (apoptosis or necrosis), the primary mechanism here is toxin-induced cellular
damage. Hypoxic injury would result from decreased oxygen availability, which is
secondary rather than primary in this case.
5. A 38-year-old patient experiences myocardial infarction with reperfusion
therapy initiated 90 minutes after symptom onset. Which of the following
complications is most likely to occur due to reperfusion injury?
A) Decreased oxygen delivery
B) Oxidative stress and free radical formation
C) Chronic ischemia
D) Collateral circulation development
E) Myocardial hibernation
CORRECT ANSWER: B) Oxidative stress and free radical formation
RATIONALE: Reperfusion injury occurs when blood flow is restored to ischemic
tissue, paradoxically causing additional cellular damage through the generation of
reactive oxygen species (ROS) and free radicals. During the reperfusion phase,
mitochondria generate excessive ROS, calcium enters cells uncontrollably, and
inflammatory mediators are released. These mechanisms cause additional
myocardial damage beyond the initial ischemic injury. While decreased oxygen
delivery causes the initial infarction, restoration of flow creates the specific injury
pattern of reperfusion. Collateral circulation and hibernation are adaptations to
chronic ischemia, not complications of acute reperfusion.
6. A 71-year-old patient with emphysema has decreased elastic recoil in the
lungs due to destruction of elastic fibers. Which cellular component is
primarily damaged?
A) Elastin in the extracellular matrix
B) Type I collagen
