SECTION 1: CELLULAR ADAPTATION, INJURY, & DEATH
(Questions 1–10)
Q1: A 72-year-old male with chronic heart failure presents with decreased exercise tolerance. On
cardiac MRI, the left ventricular wall thickness is increased, and myocyte size is enlarged. Which
cellular adaptation best explains these findings?
A. Physiologic atrophy due to chronic underperfusion
B. Pathologic hyperplasia secondary to chronic volume overload
C. Compensatory hypertrophy in response to increased afterload
D. Metaplasia of cardiac myocytes converting to skeletal muscle phenotype
,Correct Answer: C
Rationale: The patient exhibits compensatory hypertrophy, a reversible cellular adaptation where
individual cells increase in size (not number) in response to increased mechanical demand. In chronic
heart failure, elevated afterload (pressure overload) triggers myocardial cell enlargement through
increased protein synthesis and organelle production. This is distinct from hyperplasia (increase in
cell number), which does not occur in permanent cells like cardiac myocytes. Option A is incorrect
because atrophy involves cell shrinkage, not enlargement. Option B is incorrect because cardiac
myocytes are terminally differentiated and cannot undergo hyperplasia. Option D is incorrect
because metaplasia involves reversible conversion between mature epithelial cell types, not
cardiac-to-skeletal muscle transformation. For Maryville NURS611 students, recognizing
compensatory hypertrophy is clinically essential for understanding cardiac remodeling and its
progression to decompensated heart failure.
Q2: A 55-year-old woman with a history of Barrett esophagus undergoes endoscopic biopsy. The
pathologist reports replacement of normal stratified squamous epithelium with columnar epithelium
containing goblet cells. Which cellular adaptation is described?
A. Dysplasia with loss of cellular maturation and nuclear pleomorphism
B. Metaplasia representing an adaptive response to chronic acid exposure
C. Hyperplasia with increased cell proliferation in the esophageal mucosa
D. Anaplasia with complete loss of differentiation and bizarre nuclei
Correct Answer: B
,Rationale: Metaplasia is the reversible replacement of one differentiated cell type with another mature
cell type, typically in response to chronic irritation or stress. In Barrett esophagus, chronic
gastroesophageal reflux exposes the distal esophagus to acid, triggering the transformation of
squamous epithelium into intestinal-type columnar epithelium with goblet cells. While this adaptation
is protective against acid injury, it increases the risk of dysplasia and adenocarcinoma. Option A
describes dysplasia, which involves disordered cellular maturation and is considered a preneoplastic
change, not the current finding. Option C describes hyperplasia (increased cell number), which may
coexist but is not the primary histologic change described. Option D describes anaplasia, a feature of
malignant tumors with complete loss of differentiation. Maryville graduate nursing students must
recognize metaplasia as a potentially reversible adaptation that requires surveillance due to its
malignant potential.
Q3: A postmenopausal woman presents with vaginal bleeding. Endometrial biopsy reveals crowded
endometrial glands with increased gland-to-stroma ratio, nuclear stratification, and loss of polarity,
but no invasion. Which term best describes these histologic findings?
A. Simple hyperplasia without atypia
B. Complex hyperplasia with atypia (endometrial intraepithelial neoplasia)
C. Endometrial metaplasia secondary to estrogen stimulation
D. Physiologic hypertrophy of endometrial glands
Correct Answer: B
Rationale: The biopsy demonstrates complex hyperplasia with atypia, now classified as endometrial
intraepithelial neoplasia (EIN). The key features include architectural complexity (crowded glands,
increased gland-to-stroma ratio), cytologic atypia (nuclear stratification, loss of polarity), and
, absence of stromal invasion. This represents a preneoplastic lesion with significant risk of
progression to endometrial adenocarcinoma, particularly in the setting of unopposed estrogen
stimulation. Option A is incorrect because simple hyperplasia lacks the architectural complexity and
cytologic atypia described. Option C is incorrect because metaplasia involves cell type conversion, not
the glandular proliferation and atypia seen here. Option D is incorrect because hypertrophy refers to
cell enlargement, not increased cell number with cytologic atypia. For NURS611 students,
distinguishing hyperplasia with atypia from benign proliferative changes is critical for understanding
cancer progression pathways and guiding clinical management.
Q4: A 68-year-old man with severe atherosclerosis develops acute limb ischemia. Six hours later, the
affected limb shows pallor, loss of sensation, and absence of pulse. Histology reveals cell outlines
preserved but nuclei absent, with eosinophilic cytoplasm. Which type of necrosis is present?
A. Liquefactive necrosis with enzymatic digestion and cavity formation
B. Coagulative necrosis with preservation of tissue architecture
C. Caseous necrosis with amorphous granular debris and granulomatous inflammation
D. Fat necrosis with saponification and calcium deposition
Correct Answer: B
Rationale: Coagulative necrosis is the characteristic pattern of ischemic cell death in most tissues
except the brain. It results from denaturation of structural and enzymatic proteins, which preserves
the cellular and tissue architecture for several days despite loss of nuclei (karyolysis, pyknosis,
karyorrhexis). The eosinophilic cytoplasm reflects loss of basophilic RNA and denatured cytoplasmic
proteins. This pattern is typical in myocardial infarction, renal infarction, and limb ischemia. Option A
describes liquefactive necrosis, which occurs in the brain due to abundant hydrolytic enzymes and in
