RATIONALES.
PATHOPHYSIOLOGY
Prepare effectively for the NSG 5140 Advanced Pathophysiology Final Exam with this
focused study resource. It supports review of disease processes, pathophysiological
mechanisms, cellular responses, clinical manifestations, and physiological changes
associated with illness. Use the material to reinforce your understanding, review key
topics, and identify areas that may require additional study. This resource is suited for
graduate nursing students, advanced practice nursing learners, and candidates
preparing for the NSG 5140 final examination.
MULTIPLE CHOICE.
SECTION 1: CELLULAR ADAPTATION, INJURY, & NEOPLASIA (Questions 1–
20)
1. A researcher is studying the effect of chronic ischemia on cardiac
myocytes. Which cellular adaptation is MOST likely to occur in response
to this prolonged stress?
• A. Atrophy
• B. Hypertrophy
• C. Hyperplasia
• D. Metaplasia
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size in response to increased
workload or chronic stress. Cardiac myocytes are post-mitotic cells that
cannot undergo hyperplasia (increased cell number); they adapt to
chronic ischemia or increased afterload through hypertrophy.**

2. A 58-year-old male with a 40-pack-year smoking history undergoes a
bronchial biopsy. The pathologist notes replacement of normal ciliated
columnar epithelium with stratified squamous epithelium in the bronchi.
This cellular change is BEST described as:
• A. Dysplasia
• B. Metaplasia
• C. Anaplasia
• D. Neoplasia
Correct Answer: B
Rationale: Metaplasia is the reversible replacement of one differentiated
cell type with another in response to chronic irritation. Smoking causes
squamous metaplasia of the respiratory epithelium as an adaptive
response to chronic irritation. Dysplasia involves disordered cellular
growth, while anaplasia refers to loss of differentiation in malignant cells.
3. A 45-year-old female with a history of chronic gastroesophageal reflux
disease (GERD) undergoes an upper endoscopy. Biopsy of the distal
esophagus reveals columnar epithelium with goblet cells (intestinal
metaplasia). This condition is known as:
• A. Barrett's esophagus
• B. Esophageal varices
• C. Esophagitis
• D. Achalasia
Correct Answer: A
Rationale: Barrett's esophagus is the replacement of normal squamous
epithelium of the distal esophagus with columnar epithelium containing
goblet cells (intestinal metaplasia) in response to chronic acid reflux. It is
a precancerous condition associated with an increased risk of
esophageal adenocarcinoma.

4. A 62-year-old male with a history of alcohol use disorder presents with
jaundice and ascites. Liver biopsy reveals extensive fibrosis and
regenerative nodules. Which cellular process is MOST responsible for the
fibrosis?
• A. Apoptosis
• B. Necrosis
• C. Activation of hepatic stellate cells
• D. Kupffer cell proliferation
Correct Answer: C
Rationale: Hepatic stellate cells are the primary cells responsible for
fibrosis in liver disease. Upon activation by inflammatory cytokines and
oxidative stress, they transform into myofibroblasts that produce
excessive extracellular matrix (collagen), leading to cirrhosis.
5. A patient with a malignant tumor is found to have cells that vary
significantly in size and shape, with hyperchromatic nuclei and abnormal
mitotic figures. These findings are characteristic of:
• A. Benign neoplasia
• B. Dysplasia
• C. Anaplasia
• D. Metaplasia
Correct Answer: C
Rationale: Anaplasia refers to the loss of cellular differentiation in
malignant tumors, characterized by pleomorphism (variation in size and
shape), hyperchromatic nuclei, and abnormal mitotic figures. These
features indicate a high-grade, aggressive malignancy.

6. A 55-year-old female is diagnosed with breast cancer. The tumor is
found to have cells that resemble normal breast tissue and grow slowly.
The tumor is well-circumscribed and has not invaded surrounding tissues.
This tumor is MOST likely:
• A. Malignant
• B. Benign
• C. Metastatic
• D. Anaplastic
Correct Answer: B
Rationale: Benign tumors are characterized by well-differentiated cells
that resemble the tissue of origin, slow growth, well-circumscribed
borders, and lack of invasion into surrounding tissues. They do not
metastasize.
7. A patient with a myocardial infarction develops necrosis of cardiac
myocytes. Which type of necrosis is MOST characteristic of ischemic
injury in the heart?
• A. Coagulative necrosis
• B. Liquefactive necrosis
• C. Caseous necrosis
• D. Fat necrosis
Correct Answer: A
Rationale: Coagulative necrosis is the hallmark of ischemic injury in solid
organs such as the heart, kidney, and spleen. It is characterized by
preservation of tissue architecture with loss of nuclei and cytoplasmic
detail. Liquefactive necrosis is seen in the brain, caseous necrosis in
tuberculosis, and fat necrosis in pancreatic injury.
