Introduction
This comprehensive final examination evaluates the advanced nursing
student’s depth of knowledge in human pathophysiology across the
lifespan. The assessment integrates cellular and molecular mechanisms
of disease with systemic clinical manifestations. Questions address the
etiology, pathogenesis, and sequelae of major disorders, emphasizing
the interplay of genetics, environment, and host responses. The
examination uses multiple-choice and scenario-based items that require
critical analysis of clinical and laboratory data to identify the underlying
pathophysiologic processes. Success demonstrates the ability to apply
advanced pathophysiologic concepts to clinical reasoning, diagnostic
interpretation, and therapeutic decision-making essential for graduate-
,level nursing practice. This exam ensures readiness to manage complex
patient conditions through a solid foundation in disease mechanisms.
SECTION ONE: QUESTIONS 1–50
Question 1
A 65-year-old man with chronic hypertension and diabetes mellitus dies
of a myocardial infarction. Autopsy reveals an enlarged heart with left
ventricular wall thickening without chamber dilation. Which term best
describes this adaptive change?
A. Atrophy
B. Hyperplasia
C. Pathologic hypertrophy
D. Physiologic hypertrophy
C. Pathologic hypertrophy
RATIONALE: Hypertrophy is an increase in cell size resulting in
organ enlargement. In hypertension, pressure overload leads to
concentric hypertrophy of the left ventricle, a pathologic adaptation
that increases the risk of heart failure and arrhythmias. Physiologic
hypertrophy occurs in athletes. Hyperplasia involves increased cell
number, not size. Atrophy is decreased size.
Question 2
A patient with gastroesophageal reflux disease undergoes endoscopy,
and biopsy of the distal esophagus reveals columnar epithelium with
goblet cells replacing the normal stratified squamous epithelium. This is
an example of:
A. Dysplasia
B. Metaplasia
C. Anaplasia
D. Hyperplasia
B. Metaplasia
, RATIONALE: Barrett esophagus is a classic example of metaplasia,
a reversible change in which one differentiated cell type is replaced by
another cell type better able to withstand the injurious environment—
in this case, acid reflux causing squamous to columnar change.
Dysplasia refers to disordered growth, and anaplasia is a hallmark of
malignancy.
Question 3
Which of the following molecules is a key mediator of vasodilation and
increased vascular permeability during acute inflammation?
A. Thromboxane A2
B. Histamine
C. Leukotriene B4
D. IL-12
B. Histamine
RATIONALE: Histamine released from mast cells, basophils, and
platelets causes arteriolar vasodilation and increased venular
permeability early in the inflammatory response. Thromboxane A2
promotes vasoconstriction and platelet aggregation. Leukotriene B4 is a
chemotactic agent. IL-12 is involved in adaptive immunity.
Question 4
A 45-year-old woman presents with a butterfly rash, arthralgias, and
renal involvement. Laboratory studies reveal anti-double-stranded DNA
antibodies. What type of hypersensitivity reaction is primarily involved
in the pathogenesis of this disease?
A. Type I (IgE-mediated)
B. Type II (cytotoxic)
C. Type III (immune complex-mediated)
D. Type IV (delayed-type)
C. Type III (immune complex-mediated)
