SECTION 1: Cellular Adaptation, Injury, and Death
Questions 1–25
Q1. A 62-year-old client with chronic hypertension develops thickening of the left ventricular
myocardium. Which cellular adaptation does this represent?
A. Atrophy
B. Hyperplasia
C. Hypertrophy
D. Metaplasia
Correct Answer: C. Hypertrophy
Rationale: Hypertrophy is an increase in cell size that occurs in tissues incapable of cell division,
such as cardiac muscle. Chronic pressure overload from hypertension stimulates cardiomyocytes to
enlarge to meet increased workload demands. Atrophy involves shrinkage, hyperplasia involves
increased cell number, and metaplasia is replacement of one mature cell type with another.
Q2. A client who chronically abuses alcohol experiences enlargement of the liver. Which cellular
adaptation best explains this finding?
A. Atrophy
B. Hypertrophy
C. Dysplasia
D. Metaplasia
Correct Answer: B. Hypertrophy
Rationale: Hepatocytes enlarge in response to toxic exposure as they attempt to metabolize
increased alcohol loads, producing organ hypertrophy. Although hyperplasia can contribute in
organs capable of division, the primary adaptation described in alcohol-related hepatomegaly is
cellular enlargement. Dysplasia refers to disordered growth, and metaplasia is cell-type substitution.
Q3. A woman who has had multiple pregnancies experiences cervical tissue changes in which
columnar epithelium is replaced by squamous epithelium. This adaptation is known as:
2|Page
,A. Dysplasia
B. Anaplasia
C. Metaplasia
D. Hyperplasia
Correct Answer: C. Metaplasia
Rationale: Metaplasia is the reversible replacement of one mature cell type by another, often in
response to chronic irritation. In the cervix, columnar epithelium may be replaced by more resilient
squamous epithelium. Dysplasia involves abnormal cellular maturation, anaplasia is a hallmark of
malignancy, and hyperplasia is an increase in cell number.
Q4. A biopsy of bronchial tissue from a long-term smoker reveals disorganized, abnormal cell
growth with variation in cell size and shape, but the basement membrane remains intact. This
finding is most consistent with:
A. Metaplasia
B. Dysplasia
C. Anaplasia
D. Neoplasia
Correct Answer: B. Dysplasia
Rationale: Dysplasia is characterized by disordered, atypical cellular growth with pleomorphism
(variation in size and shape) and hyperchromatic nuclei, but without invasion through the basement
membrane. Metaplasia involves cell-type replacement without atypia. Anaplasia is a feature of
malignant cells, and neoplasia refers to new, uncontrolled growth.
Q5. Which cellular adaptation is considered the most reversible and represents an increase in
the number of cells in a tissue?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: C. Hyperplasia
Rationale: Hyperplasia is an increase in the number of cells in a tissue or organ, typically in
response to hormonal or compensatory stimuli, and is generally reversible when the stimulus is
removed. Hypertrophy is an increase in cell size, atrophy is shrinkage, and metaplasia is cell-type
replacement.
Q6. A client's skeletal muscle decreases in mass after prolonged immobilization following a
fracture. Which cellular adaptation does this represent?
A. Atrophy
B. Hypertrophy
3|Page
, C. Hyperplasia
D. Dysplasia
Correct Answer: A. Atrophy
Rationale: Atrophy is a decrease in cell size resulting from reduced workload, disuse, or loss of
trophic signals. Prolonged immobilization reduces muscle activity, leading to muscle fiber shrinkage.
Hypertrophy and hyperplasia involve growth, and dysplasia involves abnormal cellular development.
Q7. Which of the following best describes the mechanism by which cellular atrophy occurs?
A. Increased protein synthesis and decreased degradation
B. Decreased protein synthesis and increased protein degradation via ubiquitin-proteasome pathway
C. Increased mitosis and decreased apoptosis
D. Increased DNA replication and cell division
Correct Answer: B. Decreased protein synthesis and increased protein degradation via ubiquitin-
proteasome pathway
Rationale: Atrophy results from a combination of reduced protein synthesis and accelerated
protein degradation, largely through the ubiquitin-proteasome system and autophagy. This reduces
cell size. Increased protein synthesis and mitosis would cause growth, not atrophy.
Q8. A client experiences coagulative necrosis of the myocardium following an acute myocardial
infarction. Which description best characterizes coagulative necrosis?
A. Enzymatic digestion of tissue resulting in a liquid mass
B. Preservation of tissue architecture with a firm, pale appearance
C. Caseous, cheesy-appearing tissue with granulomatous inflammation
D. Fat saponification with chalky-white deposits
Correct Answer: B. Preservation of tissue architecture with a firm, pale appearance
Rationale: Coagulative necrosis, typical of ischemic injury in the heart, kidney, and spleen,
preserves the basic tissue architecture for a time because structural proteins are denatured but not
immediately digested. Liquefactive necrosis causes tissue liquefaction, caseous necrosis is cheesy
and granulomatous, and fat necrosis involves saponification.
Q9. A client with a bacterial brain abscess develops liquefactive necrosis. Which statement best
explains why liquefactive necrosis occurs in the brain?
A. The brain has abundant collagen, preserving tissue structure
B. The brain lacks significant structural framework and has high enzymatic activity
C. The brain is resistant to ischemic injury
D. The brain undergoes caseous necrosis exclusively
Correct Answer: B. The brain lacks significant structural framework and has high enzymatic
activity
