Nsg 5003 Final Exam |Complete Questions With
100% Rated Expert Solutions |2026 Latest Updated
INTRODUCTION
This comprehensive guide provides most tested and highly reviewed
multiple-choice questions for the NSG 5003 Advanced Pathophysiology
Final Exam. Each question is accompanied by a verified correct answer
and a detailed rationale to deepen your understanding of cellular injury,
inflammation, genetics, and systemic disease processes. This resource is
essential for mastering the complex pathophysiological concepts required
for advanced nursing practice and achieving a Grade A+ on the final exam.
Question 1
Which component of the cell produces hydrogen peroxide (H2O2) by using
oxygen to remove hydrogen atoms from specific substrates in an
oxidative reaction?
A. Lysosomes
B. Peroxisomes
C. Ribosomes
D. Oxyhydrosomes
Correct Answer: B. Peroxisomes
Rationale: Peroxisomes are small organelles that contain enzymes
,(catalase, urate oxidase) responsible for producing and degrading
hydrogen peroxide. They use oxygen to remove hydrogen atoms
from specific substrates in oxidative reactions, playing a critical
role in detoxification and lipid metabolism .
Question 2
What is a consequence of plasma membrane damage to the
mitochondria?
A. Enzymatic digestion halts deoxyribonucleic acid (DNA) synthesis.
B. Influx of calcium ions halts adenosine triphosphate (ATP) production.
C. Edema from an influx in sodium causes a reduction in ATP production.
D. Potassium shifts out of the mitochondria, which destroys the
infrastructure.
Correct Answer: B. Influx of calcium ions halts adenosine
triphosphate (ATP) production.
Rationale: When the plasma membrane is damaged, calcium ions flow
into the cell. This influx of calcium into the mitochondria disrupts the
electron transport chain and oxidative phosphorylation, halting ATP
production. This is a critical mechanism of irreversible cell injury .
Question 3
Which statement is a description of one of the characteristics of
apoptosis?
A. Apoptosis involves programmed cell death of scattered single cells.
B. Apoptosis is characterized by the swelling of the nucleus and the
cytoplasm.
,C. Apoptosis involves unpredictable patterns of cell death.
D. Apoptosis results in benign malignancies.
Correct Answer: A. Apoptosis involves programmed cell death of
scattered single cells.
Rationale: Apoptosis is a programmed, regulated form of cell death
that affects scattered individual cells rather than large areas of
tissue. Unlike necrosis, apoptosis does not cause inflammation and
is characterized by cell shrinkage, not swelling .
Question 4
During cell injury caused by hypoxia, sodium and water move into the cell
because:
A. The sodium-potassium pump is activated
B. The sodium-potassium pump fails due to lack of ATP
C. The cell membrane becomes impermeable to sodium
D. The osmotic pressure outside the cell increases
Correct Answer: B. The sodium-potassium pump fails due to lack of
ATP
Rationale: Hypoxia leads to decreased ATP production. Without
adequate ATP, the sodium-potassium pump (Na+/K+-ATPase) fails,
causing sodium and water to accumulate inside the cell, leading to
cellular swelling (hydropic degeneration) .
Question 5
What is the primary consequence of deoxyribonucleic acid (DNA)
aberrations during cell injury?
, A. Enhanced cellular repair
B. Cell death or malignant transformation
C. Increased protein synthesis
D. Improved cellular function
Correct Answer: B. Cell death or malignant transformation
Rationale: DNA aberrations (mutations, breaks, or chromosomal
abnormalities) can lead to cell death if the damage is severe, or to
malignant transformation if the cell survives with mutations that
promote uncontrolled growth .
Question 6
Obesity creates a greater risk for dehydration in people because:
A. Adipose cells contain little water because fat is water repelling.
B. The metabolic rates of obese adults are slower than those of lean
adults.
C. The rates of urine output of obese adults are higher than those of lean
adults.
D. The thirst receptors of the hypothalamus do not function effectively.
Correct Answer: A. Adipose cells contain little water because fat is
water repelling.
Rationale: Adipose tissue contains relatively little water compared
to lean tissue. In obese individuals, a greater proportion of body
weight is fat, which is hydrophobic (water-repelling), resulting in a
lower total body water percentage and increased risk for
dehydration .
