Section 1: Cellular Pathophysiology
Question 1. A patient presents with myocardial infarction. The nurse practitioner
understands that the ischemic myocardial cells initially undergo which type of
cellular adaptation?
A. Apoptosis
B. Coagulative necrosis
C. Cellular swelling (hydropic degeneration)
D. Caseous necrosis
Rationale: During the initial phase of ischemia, cells undergo cellular swelling (hydropic
degeneration) due to failure of the sodium-potassium ATPase pump, leading to intracellular
accumulation of sodium and water. This is the earliest morphological change in reversible cell
injury. If ischemia persists and blood flow is not restored, the injury progresses from reversible
to irreversible, culminating in coagulative necrosis—the characteristic necrosis pattern in
myocardial infarction. Apoptosis is a programmed, energy-dependent cell death pathway that
differs from necrosis morphologically and mechanistically. Caseous necrosis is characteristic of
tuberculosis, not ischemic injury. Understanding the spectrum from reversible injury to
irreversible necrosis is fundamental to advanced pathophysiology.
Question 2. Which of the following statements best describes the pathophysiological
mechanism of apoptosis?
A. Rapid cellular swelling, organelle dissolution, and inflammation
B. Energy-dependent programmed cell death with cell shrinkage, chromatin
condensation, and absence of inflammation
C. Unregulated enzymatic autodigestion of cellular components with exudative inflammation
D. Liquefactive necrosis with neutrophilic infiltration and abscess formation
Rationale: Apoptosis is an energy-dependent (ATP-requiring) programmed cell death
pathway characterized by cell shrinkage, chromatin condensation (pyknosis), nuclear
fragmentation (karyorrhexis), formation of apoptotic bodies, and phagocytosis by
,macrophages WITHOUT triggering an inflammatory response. Key molecular mediators
include caspases (cysteine proteases), cytochrome c release from mitochondria (intrinsic
pathway), and death receptor activation (extrinsic pathway). Unlike necrosis, apoptosis does
not cause cellular swelling, membrane rupture, or inflammation. This distinction is clinically
significant because apoptosis can be physiological (embryonic development, immune cell
selection) or pathological (viral infections, graft rejection, cancer therapy response).
Question 3. A patient with chronic GERD develops Barrett esophagus. Which
cellular adaptation has occurred?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
Rationale: Barrett esophagus is a classic example of metaplasia, in which chronic acid
exposure causes the normal stratified squamous epithelium of the esophagus to be replaced by
intestinal-type columnar epithelium (specialized intestinal metaplasia containing goblet cells).
Metaplasia is a reversible adaptive response in which one mature cell type is replaced by
another mature cell type, driven by environmental stressors that favor survival of the
replacement cell type. While metaplasia itself is adaptive, it represents a precursor to dysplasia
(abnormal cell growth with malignant potential) and ultimately adenocarcinoma. Hyperplasia
is an increase in the number of cells, dysplasia refers to disordered cellular maturation, and
anaplasia describes undifferentiated tumor cells.
Question 4. A 65-year-old patient presents with a non-healing wound on the lower
extremity. The advanced practice nurse understands that which of the following are
characteristics of the proliferative phase of wound healing? (Select all that apply.)
(Select all that apply.)
A. Angiogenesis and granulation tissue formation
B. Fibroblast migration and collagen synthesis
C. Platelet aggregation and fibrin clot formation
D. Epithelial cell migration across the wound surface
E. Contraction of the wound by myofibroblasts
Rationale: The proliferative phase (days 4-24) is characterized by four key processes:
angiogenesis (formation of new blood vessels from endothelial cells via VEGF stimulation),
granulation tissue formation (fibroblasts synthesize collagen and extracellular matrix),
epithelialization (migration of epithelial cells across the wound surface), and wound contraction
(myofibroblasts pull wound edges together). Platelet aggregation and fibrin clot formation
occur during the hemostasis/inflammatory phase (immediate to 72 hours), not the proliferative
phase. The inflammatory phase involves neutrophil and macrophage infiltration to clear debris
and bacteria. The maturation/remodeling phase (days 21 onward) involves collagen
reorganization and scar strengthening.
Question 5. A patient with a history of chronic alcohol abuse develops
hepatomegaly. A liver biopsy reveals enlarged hepatocytes filled with large lipid
droplets. This pathologic change is best described as:
A. Steatosis (fatty change)
, B. Hyaline degeneration
C. Amyloidosis
D. Melanosis
Rationale: Steatosis (fatty change) is the accumulation of triglycerides within hepatocytes,
appearing as clear lipid droplets that may displace the nucleus to the periphery of the cell.
Chronic alcohol abuse is the most common cause of hepatic steatosis because alcohol
metabolism increases NADH/NAD+ ratio, promotes fatty acid synthesis, inhibits fatty acid
oxidation, and impairs lipoprotein secretion. This represents a reversible cellular injury if the
insult is removed. If alcohol abuse continues, steatosis can progress to steatohepatitis (alcoholic
hepatitis), fibrosis, and ultimately cirrhosis. Hyaline degeneration refers to pink, glassy-
appearing protein accumulations (e.g., Mallory bodies in alcoholic liver disease), amyloidosis
involves extracellular deposition of amyloid protein, and melanosis refers to melanin
accumulation.
Section 2: Immune System Disorders
Question 6. A 28-year-old woman develops anaphylaxis after receiving penicillin.
Which immunoglobulin and effector mechanism are primarily responsible for this
Type I hypersensitivity reaction?
A. IgG and complement-mediated cytotoxicity
B. IgE and mast cell degranulation
C. IgM and immune complex formation
D. IgA and T-cell-mediated cytotoxicity
Rationale: Type I hypersensitivity (immediate hypersensitivity) is mediated by IgE antibodies
bound to high-affinity Fc receptors on mast cells and basophils. Upon re-exposure to the antigen
(allergen), cross-linking of IgE receptors triggers mast cell degranulation, releasing preformed
mediators (histamine, tryptase, heparin) and synthesizing newly formed mediators
(leukotrienes, prostaglandins, platelet-activating factor). Histamine causes vasodilation,
increased vascular permeability, bronchospasm, and increased mucus production. Systemic
anaphylaxis is a life-threatening emergency requiring immediate epinephrine (alpha-1 agonist
for vasoconstriction and bronchodilation, beta-1 for increased cardiac output). IgG mediates
Type II and Type III hypersensitivity, IgM mediates complement activation, and IgA protects
mucosal surfaces.
Question 7. A patient with systemic lupus erythematosus (SLE) presents with malar
rash, joint pain, and proteinuria. The pathophysiology of SLE is best described as:
A. Type III hypersensitivity with immune complex deposition in tissues
B. Type IV delayed hypersensitivity with T-cell-mediated tissue damage
C. Type I hypersensitivity with IgE-mediated mast cell activation
D. Type II hypersensitivity with antibody-mediated cell destruction
Rationale: SLE is a chronic, systemic autoimmune disease primarily mediated by Type III
hypersensitivity reactions. Autoantibodies (anti-nuclear antibodies, anti-dsDNA, anti-Smith)
form immune complexes that deposit in tissues—particularly the kidneys (glomerulonephritis),
skin (malar rash), joints (arthralgia/arthritis), serosal surfaces (serositis), and blood vessels
(vasculitis). Immune complex deposition activates complement (C3a, C5a as anaphylatoxins),
recruits neutrophils, and causes tissue damage through the membrane attack complex (MAC)
