disease mechanisms essential for clinical assessment, differential diagnosis, and treatment planning. This comprehensive study guide
contains all possible questions and verified answers from the course exam bank, organized by competency domain with detailed rationales.
Answer Format
All questions are presented in bold text for clear distinction and readability.
All correct answers are presented in bold and lime green, followed by clearly defined, pathophysiologically accurate rationales
in italic format that reinforce disease mechanisms, clinical correlations, and advanced clinical judgment required for WGU D115
objective assessment success.
Cellular Adaptation & Injury (Questions 1-25)
Cellular
1
, A patient with chronic hypertension develops left ventricular hypertrophy. This is an
example of:
A) Atrophy
B) Hypertrophy
C) Hyperplasia
D) Metaplasia
Correct Answer: B) Hypertrophy
Rationale: Hypertrophy is an increase in cell size in response to increased workload. Left ventricular hypertrophy
occurs in response to chronic pressure overload from hypertension.
Cellular
2
Which cellular adaptation is characterized by a decrease in cell size?
A) Hypertrophy
B) Hyperplasia
C) Atrophy
D) Metaplasia
Correct Answer: C) Atrophy
Rationale: Atrophy is a decrease in cell size and function due to decreased workload, loss of innervation, decreased
blood supply, or inadequate nutrition.
Cellular
3
Barrett's esophagus is an example of:
A) Dysplasia
B) Metaplasia
C) Hyperplasia
D) Anaplasia
Correct Answer: B) Metaplasia
Rationale: Barrett's esophagus is metaplasia where normal squamous epithelium is replaced by columnar epithelium
in response to chronic acid exposure.
Cellular
4
Which type of cell death is programmed and controlled?
A) Necrosis
B) Apoptosis
C) Gangrene
D) Infarction
, Correct Answer: B) Apoptosis
Rationale: Apoptosis is programmed cell death that is controlled and does not cause inflammation. Necrosis is
uncontrolled cell death causing inflammation.
Cellular
5
Cervical dysplasia detected on Pap smear indicates:
A) Benign adaptation
B) Premalignant changes
C) Normal variation
D) Infection only
Correct Answer: B) Premalignant changes
Rationale: Dysplasia is disordered growth and maturation of cells, considered premalignant. Cervical dysplasia can
progress to cervical cancer if untreated.
Cellular
6
Which type of necrosis is characteristic of myocardial infarction?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Fat necrosis
Correct Answer: A) Coagulative necrosis
Rationale: Coagulative necrosis occurs in hypoxic death of cells (except brain). Myocardial infarction causes
coagulative necrosis due to ischemia.
Cellular
7
Brain tissue undergoes which type of necrosis after ischemic injury?
A) Coagulative necrosis
B) Liquefactive necrosis
C) Caseous necrosis
D) Gangrenous necrosis
Correct Answer: B) Liquefactive necrosis
Rationale: Brain tissue undergoes liquefactive necrosis due to high lysosomal enzyme content, resulting in soft,
liquefied tissue.
Cellular
8
Which adaptation involves an increase in cell number?
, A) Hypertrophy
B) Hyperplasia
C) Atrophy
D) Metaplasia
Correct Answer: B) Hyperplasia
Rationale: Hyperplasia is an increase in cell number in response to stimulus. Can be physiologic (breast during
pregnancy) or pathologic (endometrial hyperplasia).
Cellular
9
Free radical injury to cells is caused by:
A) Decreased oxygen
B) Reactive oxygen species
C) Decreased ATP
D) Increased protein synthesis
Correct Answer: B) Reactive oxygen species
Rationale: Free radicals (reactive oxygen species) cause oxidative damage to cell membranes, proteins, and DNA,
contributing to cell injury and aging.
Cellular
10
Which organelle is responsible for ATP production?
A) Ribosome
B) Mitochondria
C) Golgi apparatus
D) Endoplasmic reticulum
Correct Answer: B) Mitochondria
Rationale: Mitochondria produce ATP through oxidative phosphorylation. Ischemia causes mitochondrial dysfunction
and ATP depletion.
Cellular
11
Sodium-potassium pump failure during ischemia results in:
A) Cell shrinkage
B) Cellular swelling
C) Cell division
D) Cell differentiation
Correct Answer: B) Cellular swelling
