INTRODUCTION
This comprehensive final examination assesses the advanced
pathophysiology knowledge and clinical reasoning skills required of the
graduate nursing student. It evaluates foundational mechanisms of cellular
adaptation, injury, inflammation, immunity, and system-based
pathophysiology across the lifespan. The examination employs multiple-
choice and case-based questions to simulate realistic clinical encounters.
Emphasis is placed on critical thinking, integration of pathophysiologic
mechanisms with clinical presentation, and the application of evidence-
based diagnostic reasoning. This assessment prepares candidates for the
rigor of advanced practice nursing certification and real-world clinical
practice.
SECTION ONE: QUESTIONS 1–100
1. A 62-year-old male with a 40-pack-year smoking history undergoes
a lung biopsy that reveals replacement of normal ciliated columnar
,epithelium with stratified squamous epithelium. Which cellular
adaptation is present?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
C. Metaplasia
RATIONALE: Metaplasia is the reversible replacement of one
differentiated cell type with another in response to chronic irritation. In
smokers, ciliated columnar epithelium is replaced by stratified squamous
epithelium, which is more resistant to injury but loses mucus clearance
function.
2. A 58-year-old female with long-standing hypertension develops left
ventricular wall thickening. Which cellular adaptation is primarily
responsible for this finding?
A. Hyperplasia of cardiac muscle cells
B. Hypertrophy of cardiac muscle cells
C. Metaplasia of cardiac tissue
D. Dysplasia of the myocardium
B. Hypertrophy of cardiac muscle cells
RATIONALE: Hypertension increases the workload on the left ventricle,
leading to hypertrophy—an increase in cell size without an increase in cell
number. Cardiac muscle cells are terminally differentiated and cannot
undergo hyperplasia.
3. A 45-year-old male with chronic alcohol use disorder presents with
confusion, ataxia, and ophthalmoplegia. Which vitamin deficiency is
responsible for this condition?
A. Vitamin B12
B. Thiamine (B1)
C. Folate
D. Vitamin C
, B. Thiamine (B1)
RATIONALE: Wernicke encephalopathy is caused by thiamine
deficiency, common in chronic alcohol use. The classic triad is confusion,
ataxia, and ophthalmoplegia. It is a medical emergency requiring
immediate thiamine replacement.
4. A 28-year-old female with systemic lupus erythematosus has a
kidney biopsy showing immune complex deposition in the glomerular
basement membrane. Which type of hypersensitivity reaction is
primarily responsible?
A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
C. Type III hypersensitivity
RATIONALE: Type III hypersensitivity involves deposition of antigen-
antibody immune complexes in tissues, leading to complement activation
and inflammation. Lupus nephritis is a classic example of this mechanism.
5. A 32-year-old male sustains a deep laceration. Which cell type is
primarily responsible for synthesizing collagen and forming the scar
matrix during wound healing?
A. Neutrophils
B. Macrophages
C. Fibroblasts
D. Endothelial cells
C. Fibroblasts
RATIONALE: Fibroblasts migrate into the wound and synthesize type III
collagen, which is later remodeled to type I collagen. They are the principal
cells responsible for scar formation.
, 6. A child is diagnosed with X-linked agammaglobulinemia. Which
pathophysiologic mechanism best explains the increased
susceptibility to bacterial infections?
A. Defective T-cell mediated immunity
B. Failure of B-cell maturation and antibody production
C. Impaired phagocyte oxidative burst
D. Complement deficiency
B. Failure of B-cell maturation and antibody production
RATIONALE: X-linked agammaglobulinemia results from a mutation in
Bruton tyrosine kinase (BTK), causing failure of pre-B cells to mature into B
cells. This leads to absent or markedly reduced immunoglobulins and
recurrent bacterial infections.
7. A 52-year-old male with diabetic ketoacidosis has a blood glucose
of 480 mg/dL and an arterial pH of 7.20. Which compensatory
mechanism is expected?
A. Hyperventilation to decrease PaCO2
B. Hypoventilation to increase PaCO2
C. Increased renal bicarbonate excretion
D. Increased renal hydrogen ion excretion
A. Hyperventilation to decrease PaCO2
RATIONALE: Metabolic acidosis triggers respiratory compensation via
hyperventilation (Kussmaul respirations) to blow off CO2 and raise pH.
Renal compensation occurs over days, not acutely.
8. A 70-year-old male with atrial fibrillation develops a stroke. Which
mechanism most likely caused the stroke?
A. Thrombotic occlusion of a cerebral artery
B. Embolic occlusion from a left atrial thrombus
C. Hemorrhagic rupture of a cerebral artery
D. Vasospasm of cerebral arteries
