SECTION 1: CELLULAR REGULATION
Questions 1–8
1. Which process best describes cellular adaptation when a tissue increases the size of its
existing cells in response to increased workload?
A) Hypertrophy
B) Hyperplasia
C) Atrophy
D) Metaplasia
Correct Answer: Hypertrophy
Rationale: Hypertrophy is an increase in individual cell size and commonly occurs when cells
experience increased workload. Hyperplasia involves an increase in cell number, while
atrophy represents decreased cell size. Metaplasia involves replacement of one mature cell
type with another, often as an adaptive response to chronic irritation.
2. A client has prolonged immobilization of an extremity. Which cellular change would the
nurse expect in the affected muscles?
A) Hyperplasia
B) Atrophy
C) Dysplasia
D) Hypertrophy
Correct Answer: Atrophy
Rationale: Atrophy occurs when cells decrease in size because of reduced workload, disuse,
inadequate nutrition, or other factors. Prolonged immobilization decreases muscle activity
and therefore promotes muscle wasting. Hypertrophy would represent enlargement,
whereas hyperplasia represents increased cell number rather than the typical response to
prolonged disuse.
3. What distinguishes hyperplasia from hypertrophy?
A) Hyperplasia involves irreversible cellular death.
B) Hyperplasia occurs only in malignant tissue.
C) Hyperplasia involves an increase in cell number.
,D) Hyperplasia always causes organ failure.
Correct Answer: Hyperplasia involves an increase in cell number.
Rationale: Hyperplasia refers specifically to an increase in the number of cells within a tissue
or organ. Hypertrophy, in contrast, is enlargement of individual cells. Hyperplasia may be
physiologic or pathologic and does not inherently mean malignancy or irreversible injury.
4. Which finding most strongly suggests that a cellular change has progressed from
adaptation toward injury?
A) Temporary increase in metabolic activity
B) Mild reversible swelling that resolves
C) Increased functional reserve
D) Persistent membrane damage with loss of cellular function
Correct Answer: Persistent membrane damage with loss of cellular function
Rationale: Persistent membrane injury interferes with cellular integrity, transport
mechanisms, and normal function. Reversible changes can resolve when the cause is
removed, whereas continuing membrane damage may progress toward irreversible injury
and cell death. Loss of cellular function is therefore a significant warning sign of advancing
cellular injury.
5. Why is oxygen particularly important to cellular regulation?
A) It supports aerobic ATP production needed for cellular processes.
B) It prevents every form of inflammation.
C) It eliminates all cellular waste directly.
D) It prevents DNA from undergoing any mutation.
Correct Answer: It supports aerobic ATP production needed for cellular processes.
Rationale: Oxygen allows cells to generate substantial amounts of ATP through aerobic
metabolism. ATP supplies energy for membrane transport, protein synthesis, muscle activity,
and other cellular functions. Oxygen deprivation therefore threatens cellular energy
production and can eventually cause membrane dysfunction, injury, and cell death.
6. A tissue receives inadequate oxygen for an extended period. Which consequence is
most concerning?
A) Temporary increase in ATP production
B) Progression from reversible injury to irreversible cellular damage
C) Immediate tissue regeneration
,D) Increased oxygen delivery to surrounding cells
Correct Answer: Progression from reversible injury to irreversible cellular damage
Rationale: Prolonged oxygen deprivation reduces ATP production and disrupts essential
cellular processes. Initially, injury may be reversible if oxygenation is restored promptly.
Continued hypoxia can cause membrane damage, mitochondrial dysfunction, and eventually
irreversible injury and cell death.
7. Which assessment finding would most directly suggest impaired cellular oxygen use?
A) Warm, dry skin
B) Increased appetite
C) Cyanosis accompanied by altered mental status
D) Increased urinary output
Correct Answer: Cyanosis accompanied by altered mental status
Rationale: Cyanosis can indicate inadequate oxygenation, while altered mental status may
reflect impaired oxygen delivery to the brain. Together, these findings warrant prompt
assessment of oxygenation and circulation. Appetite and urinary output do not directly
indicate impaired cellular oxygen utilization.
8. A nurse explains that cellular regulation depends partly on maintaining a stable internal
environment. Which term describes this principle?
A) Differentiation
B) Apoptosis
C) Metastasis
D) Homeostasis
Correct Answer: Homeostasis
Rationale: Homeostasis is the maintenance of relatively stable internal conditions despite
changes inside or outside the body. Cellular and organ systems continually adjust processes
to maintain appropriate temperature, pH, fluid balance, oxygenation, and other variables.
Disruption of homeostasis can contribute to cellular dysfunction and disease.
SECTION 2: PERFUSION
Questions 9–16
9. What is the primary purpose of adequate tissue perfusion?
A) To increase body temperature
B) To deliver oxygen and nutrients while removing metabolic waste
, C) To prevent every inflammatory response
D) To eliminate the need for cellular metabolism
Correct Answer: To deliver oxygen and nutrients while removing metabolic waste
Rationale: Adequate perfusion supplies tissues with oxygen and nutrients required for
metabolism and removes carbon dioxide and other metabolic wastes. Perfusion depends on
effective cardiac output, circulating volume, vascular function, and adequate oxygen content.
Impaired perfusion can rapidly threaten tissue viability.
10. Which assessment finding is most consistent with poor peripheral perfusion?
A) Warm extremities with brisk capillary refill
B) Bounding peripheral pulses
C) Cool extremity with delayed capillary refill
D) Pink skin with normal sensation
Correct Answer: Cool extremity with delayed capillary refill
Rationale: Reduced peripheral blood flow can produce cool skin, pallor, diminished pulses,
and delayed capillary refill. These findings suggest that oxygenated blood is not reaching the
tissue adequately. The nurse should assess the affected extremity further and compare
findings with the opposite side when appropriate.
11. A patient has reduced cardiac output. Which physiological problem is most directly
expected?
A) Decreased tissue perfusion
B) Increased oxygen delivery
C) Increased renal filtration
D) Improved cellular metabolism
Correct Answer: Decreased tissue perfusion
Rationale: Cardiac output represents the amount of blood pumped by the heart each minute.
When cardiac output falls, less blood may be delivered to organs and tissues. This can
decrease oxygen and nutrient delivery and impair removal of metabolic waste.
12. Which factor can contribute directly to impaired tissue perfusion?
A) Adequate circulating volume
B) Normal vascular tone
C) Effective cardiac contraction
D) Severe hypovolemia
