150 HIGH-YIELD REVIEW QUESTIONS FOR GRADUATE NURSING STUDENTS
SECTION 1: CELLULAR ADAPTATION, INJURY, AND DEATH (Questions 1–20)
1. A cell that undergoes reversible enlargement in response to increased functional
demand is demonstrating which adaptive process?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Rationale: Hypertrophy is an increase in cell size without an increase in cell number,
typically seen in tissues incapable of dividing (cardiac muscle, skeletal muscle).
Hyperplasia involves increased cell number; metaplasia is replacement of one mature cell
type with another; dysplasia refers to disordered, atypical cellular growth that is not a true
adaptive response.
2. Which cellular adaptation involves replacement of one differentiated cell type with
another mature cell type better suited to a stressful environment?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Anaplasia
Rationale: Metaplasia is a reversible substitution of one mature cell type for another, most
commonly seen in the respiratory epithelium of smokers (columnar to squamous). It is an
adaptive response but can predispose to malignancy. Anaplasia denotes lack of
differentiation and is characteristic of malignant cells.
,3. A biopsy of cervical tissue reveals disordered arrangement of cells with variation in
size and shape, but the basement membrane remains intact. This finding is best
described as:
A. Carcinoma in situ
B. Dysplasia
C. Metaplasia
D. Hyperplasia
Rationale: Dysplasia refers to disordered, atypical cellular proliferation with
pleomorphism and hyperchromasia, but without invasion through the basement
membrane. Carcinoma in situ would show full-thickness dysplasia without basement
membrane breach but is considered a more advanced malignant precursor. Metaplasia
and hyperplasia do not feature the atypical cellular features described.
4. Which of the following best describes the mechanism of cellular injury in ischemia-
reperfusion injury?
A. Direct mechanical disruption of cell membranes
B. Generation of reactive oxygen species and calcium overload upon restoration of
blood flow
C. Deficiency of ATP during the ischemic period only
D. Activation of the complement cascade by antibodies
Rationale: Reperfusion injury occurs when blood flow is restored to ischemic tissue,
leading to a burst of reactive oxygen species, calcium influx, and inflammatory mediator
release that paradoxically worsens cellular damage. ATP depletion occurs during ischemia
itself, not specifically at reperfusion. Antibody-mediated complement activation describes
type II hypersensitivity.
5. The most common mechanism of reversible cell injury is:
A. ATP depletion and cellular swelling
B. DNA fragmentation
C. Membrane rupture with enzymatic digestion
D. Nuclear pyknosis
,Rationale: ATP depletion from hypoxia or toxin exposure leads to failure of the Na+/K+
ATPase pump, causing sodium and water accumulation and cellular swelling — the
hallmark of reversible injury. DNA fragmentation and membrane rupture are features of
irreversible injury or apoptosis.
6. Which form of cell death is characterized by cell shrinkage, chromatin
condensation, and formation of apoptotic bodies without inflammation?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Apoptosis
D. Fat necrosis
Rationale: Apoptosis is programmed cell death featuring cell shrinkage, nuclear
condensation (pyknosis), and formation of apoptotic bodies that are phagocytosed without
inciting inflammation. Necrosis, by contrast, involves cell swelling and inflammatory
response. Coagulative, liquefactive, and fat necrosis are all forms of necrosis.
7. Coagulative necrosis is most commonly associated with which type of injury?
A. Ischemic injury to the heart, kidney, or spleen
B. Bacterial abscess formation in the brain
C. Enzymatic destruction of pancreatic tissue
D. Traumatic injury to adipose tissue
Rationale: Coagulative necrosis results from ischemia in tissues other than the brain,
preserving tissue architecture with a "ghost" outline of cells. Liquefactive necrosis occurs
in bacterial abscesses and brain infarcts; enzymatic fat necrosis occurs in acute
pancreatitis; fat necrosis also follows trauma to adipose tissue.
8. Which intracellular organelle is most directly responsible for ATP production and,
when damaged, triggers the intrinsic pathway of apoptosis?
A. Lysosome
B. Mitochondrion
C. Endoplasmic reticulum
D. Golgi apparatus
, Rationale: Mitochondria produce ATP via oxidative phosphorylation. Mitochondrial
membrane permeabilization releases cytochrome c, which activates caspases and
initiates the intrinsic apoptotic pathway. Lysosomes contain hydrolytic enzymes involved in
necrosis; the ER and Golgi are involved in protein processing.
9. Free radical injury is best mitigated by which of the following endogenous
mechanisms?
A. Antioxidants such as glutathione, superoxide dismutase, and catalase
B. Complement activation
C. Antibody production
D. Clotting cascade activation
Rationale: Cells defend against free radical injury through antioxidants (glutathione,
vitamins E and C), and enzymes such as superoxide dismutase, catalase, and glutathione
peroxidase. Complement, antibodies, and clotting factors are unrelated to direct free
radical neutralization.
10. A patient with chronic hypertension develops left ventricular wall thickening. This
is an example of:
A. Pathologic hypertrophy
B. Physiologic hyperplasia
C. Atrophy
D. Metaplasia
Rationale: Chronic pressure overload from hypertension causes pathologic hypertrophy of
cardiac myocytes, increasing wall thickness and reducing chamber compliance.
Physiologic hypertrophy occurs with exercise; hyperplasia involves increased cell number;
atrophy is shrinkage; metaplasia is cell type replacement.
11. Which of the following is a characteristic of irreversible cell injury?
A. Cellular swelling
B. Severe membrane damage with enzyme leakage and mitochondrial dysfunction
C. Reversible blebbing of the plasma membrane
D. Ribosomal detachment from the endoplasmic reticulum
