Core Domains
• Cellular Adaptation, Injury, and Death
• Inflammation and Tissue Repair
• Fluid, Electrolyte, and Acid-Base Disorders
• Genetics, Epigenetics, and Congenital Disorders
• Neoplasia and Cancer Biology
• Immune System Alterations and Hypersensitivity
• Stress and Allostatic Load (HPA Axis)
• Hematologic Pathophysiology
• Cardiovascular Pathophysiology
• Respiratory and Renal Pathophysiology
Introduction
This comprehensive examination assesses the advanced pathophysiological
knowledge and clinical reasoning skills required for graduate-level nursing
practice. The assessment evaluates understanding of cellular adaptation
mechanisms, injury pathways, inflammation and tissue repair, fluid and
electrolyte imbalances, acid-base disorders, genetic and epigenetic influences,
neoplastic transformation, immune system alterations, stress physiology,
hematologic and cardiovascular disorders, respiratory pathology, and renal
,dysfunction. The exam employs multiple-choice questions and scenario-based
items designed to test real-world application and clinical decision-making.
Candidates must demonstrate the ability to analyze complex
pathophysiological processes across the lifespan and apply these concepts to
patient assessment and management. A passing score demonstrates readiness
to synthesize advanced pathophysiology in evidence-based practice.
SECTION ONE: QUESTIONS 1–100
1. A cell decreases in size and metabolic activity in response to
decreased workload. Which term describes this adaptation?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
RATIONALE: Atrophy is a decrease in cell size and function due to
decreased workload, denervation, reduced blood supply, or inadequate
nutrition. Hypertrophy is an increase in cell size; hyperplasia is an increase in
cell number; metaplasia is the reversible replacement of one cell type with
another.
2. A patient with chronic hypertension develops thickening of the left
ventricular wall. Which cellular adaptation is responsible?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Dysplasia
RATIONALE: Hypertrophy is an increase in cell size in response to
increased workload. In hypertension, the left ventricle works harder, causing
,myocyte hypertrophy. Cardiac myocytes are terminally differentiated and
cannot undergo hyperplasia.
3. In a cell exposed to chronic hypoxia, which adaptive response is
primarily mediated by hypoxia-inducible factor 1 (HIF-1) and leads to
increased oxygen delivery?
A. Atrophy due to decreased protein synthesis
B. Hyperplasia of capillary endothelial cells
C. Metaplasia from columnar to squamous epithelium
D. Hypertrophy of existing smooth muscle cells
RATIONALE: HIF-1 upregulates VEGF, promoting angiogenesis (capillary
hyperplasia) to improve oxygen delivery. Atrophy is a maladaptive response to
reduced demand, not hypoxia. Metaplasia is a change in cell type, often due to
chronic irritation.
4. A pathologist observes tissue with shrunken, eosinophilic cells and
pyknotic nuclei, but no inflammatory response. Which type of cell
death is most likely?
A. Necrosis due to ATP depletion and membrane rupture
B. Apoptosis via caspase activation and DNA fragmentation
C. Necroptosis mediated by RIPK1/RIPK3 and MLKL
D. Autophagy leading to lysosomal digestion of organelles
RATIONALE: Apoptosis features cell shrinkage, eosinophilia, pyknosis,
and absence of inflammation because cellular contents are packaged into
apoptotic bodies. Necrosis involves cell swelling and inflammation.
5. In ischemic injury, the transition from reversible to irreversible cell
damage is most closely associated with which event?
, A. Swelling of the endoplasmic reticulum and loss of ribosomes
B. Depletion of ATP to less than 50% of normal levels
C. Massive influx of calcium into the mitochondria and activation of
phospholipases
D. Reduction in pH due to anaerobic glycolysis
RATIONALE: Irreversible injury is marked by mitochondrial calcium
overload, opening of the mitochondrial permeability transition pore, and
activation of phospholipases and proteases. ATP depletion and ER swelling
are reversible findings.
6. A patient with acute pancreatitis develops areas of chalky white
necrotic fat in the abdomen. Which type of necrosis is this?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
RATIONALE: Fat necrosis occurs in acute pancreatitis when pancreatic
lipases digest fat cells, producing chalky white deposits of calcium soaps.
Coagulative necrosis occurs in ischemic injury; liquefactive in brain infarcts
and abscesses; caseous in tuberculosis.
7. Which type of necrosis is characteristic of tuberculosis and has a soft,
cheese-like appearance?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
