NSG 5003 Week 1–10 Knowledge Check Quizzes |
Advanced Pathophysiology Complete Answers
2025/2026
INTRODUCTION
This comprehensive quiz bank provides practice questions for NSG 5003
Advanced Pathophysiology, covering all weekly knowledge checks from
Weeks 1 through 10. It includes verified answers and detailed rationales
for cellular biology, genetics, inflammation, immunity, and organ system
pathophysiology. This resource ensures thorough preparation for weekly
quizzes and comprehensive exams.
Question 1
An organelle that is responsible for metabolism of cellular energy is
referred to which of the following cell structures?
A. Golgi complex
B. Mitochondrion
C. Endoplasmic reticulum
D. Nucleolus
Correct Answer: B. Mitochondrion
Rationale: The mitochondrion is the organelle responsible for metabolism
of cellular energy through oxidative phosphorylation and ATP production.
,The Golgi complex is involved in protein modification and packaging. The
endoplasmic reticulum is involved in protein and lipid synthesis. The
nucleolus is involved in ribosome synthesis.
Question 2
Which of the following options is a chemical agent that causes cell
injury?
A. Radiation
B. Hypoxia
C. Bacteria
D. Poison
Correct Answer: D. Poison
Rationale: Poison is a chemical agent that causes cell injury. Radiation is
a physical agent. Hypoxia is a hypoxic injury. Bacteria are biological
agents.
Question 3
Breast changes of a girl in puberty or of a pregnant woman describe
which type of cellular adaptation?
A. Hypertrophy
B. Dysplasia
C. Hyperplasia
D. Metaplasia
Correct Answer: C. Hyperplasia
Rationale: Breast changes during puberty and pregnancy are examples of
,hyperplasia, an increase in the number of cells in a tissue or organ. This
is a normal physiological response to hormonal stimulation.
Question 4
An active process of programmed cellular self-destruction (cell
death) describes which of the following cell functions?
A. Apoptosis
B. Necrosis
C. Adaptation
D. Fragmentation
Correct Answer: A. Apoptosis
Rationale: Apoptosis is an active, programmed process of cellular self-
destruction. It is a normal physiological process that eliminates damaged
or unnecessary cells without causing inflammation.
Question 5
When extracellular fluid is hypotonic what is the resulting impact on
the cell?
A. Cell swelling
B. No change in cell size
C. Cell shrinkage
D. Cell death
Correct Answer: A. Cell swelling
Rationale: When extracellular fluid is hypotonic (lower solute
concentration than the cell), water moves into the cell by osmosis,
causing the cell to swell.
, Question 6
Which of the following is the most common cause of cellular injury?
A. Hypoxia
B. Chemical injury
C. Infectious injury
D. Immunologic injury
Correct Answer: A. Hypoxia
Rationale: Hypoxia, or oxygen deprivation, is the most common cause of
cellular injury. It leads to ATP depletion, anaerobic metabolism, and cell
death.
Question 7
What is the term for programmed cell death?
A. Necrosis
B. Apoptosis
C. Autolysis
D. Karyolysis
Correct Answer: B. Apoptosis
Rationale: Apoptosis is programmed cell death, a regulated process that
eliminates damaged or unnecessary cells. Necrosis is unregulated cell
death. Autolysis is self-digestion of cells. Karyolysis is dissolution of the
nucleus.
Question 8
Which type of necrosis is characterized by coagulation of proteins
and is commonly seen in ischemic injury?
