INTRODUCTION
This comprehensive study guide provides practice questions for NSG
5003 Advanced Pathophysiology, covering cellular biology, genetics,
inflammation, immunity, and organ system pathophysiology. It includes
verified answers and detailed rationales for high-yield concepts tested on
graduate nursing exams. This resource ensures thorough preparation for
exam success.
Question 1
A 15-year-old boy suffered a complete separation of a ligament from
its bony attachment. This injury is known as:
A. Lateral epicondylopathy
B. Crepitus
C. Avulsion
D. Malunion
Correct Answer: C. Avulsion
Rationale: An avulsion is the complete separation of a ligament from its
bony attachment. Lateral epicondylopathy is inflammation of the tendon at
,the elbow. Crepitus is a crackling sound. Malunion is improper healing of a
fracture.
Question 2
Joints are classified based on the degree of movement they permit
or on the connecting tissues that hold them together. A joint in
which the two bony surfaces are united by a ligament or membrane
is called:
A. Articulation
B. Symphysis
C. Syndesmosis
D. Synchondrosis
Correct Answer: C. Syndesmosis
Rationale: A syndesmosis is a joint in which the two bony surfaces are
united by a ligament or membrane. Articulation is a general term for a
joint. Symphysis is a joint united by fibrocartilage. Synchondrosis is a joint
united by hyaline cartilage.
Question 3
During DKA, insulin counter-regulatory hormones, such as
catecholamines and cortisol, increase. Profound insulin deficiency
results in:
A. Decreased fat mobilization
B. Activation of glucose forming pathways in the liver
C. Increased glucose uptake
D. Activation of bicarbonate buffering
,Correct Answer: B. Activation of glucose forming pathways in the
liver
Rationale: In DKA, profound insulin deficiency leads to activation of
glucose-forming pathways in the liver (gluconeogenesis), contributing to
hyperglycemia. Decreased fat mobilization is incorrect; fat mobilization
increases. Increased glucose uptake is incorrect; glucose uptake
decreases. Activation of bicarbonate buffering is not the primary result of
insulin deficiency.
Question 4
A 24-year-old mother visits her obstetrician's office 1 week after
delivering her baby. She is having trouble with breast-feeding and
milk expression. The obstetrician prescribes a nasal spray that will
stimulate the posterior pituitary to release which one of the
following hormones?
A. Oxytocin
B. Prolactin
C. Calcitonin
D. Incretin
Correct Answer: A. Oxytocin
Rationale: Oxytocin is released by the posterior pituitary and stimulates
milk ejection (let-down) during breastfeeding. Prolactin is released by the
anterior pituitary and stimulates milk production. Calcitonin is involved in
calcium metabolism. Incretin is involved in glucose metabolism.
, Question 5
Bone formation requires collagen synthesis, fiber formation, and
mineralization. The majority of the mineral content in the body is an
analog of which naturally occurring mineral?
A. Periosteum
B. Calcium phosphate
C. Hydroxyapatite
D. Calcium carbonate
Correct Answer: C. Hydroxyapatite
Rationale: Hydroxyapatite is the primary mineral component of bone,
consisting of calcium phosphate. Periosteum is the membrane covering
bone. Calcium phosphate is a component of hydroxyapatite but not the
mineral analog itself. Calcium carbonate is not the primary bone mineral.
Question 6
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
