INTRODUCTION
This comprehensive guide provides most tested and highly reviewed
multiple-choice questions spanning Weeks 1 through 10 of the NSG 5003
Advanced Pathophysiology course. 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 all weekly knowledge checks.
QUIZ 1 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 injury occurs when a ligament or tendon is
completely separated from its bony attachment, often taking a piece
of bone with it. Lateral epicondylopathy involves degenerative
changes at the tendon attachment, crepitus is a grating sensation,
and malunion refers to 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. Syndesmosis
B. Gomphosis
C. Articulation
D. Symphysis
Correct Answer: A. Syndesmosis
Rationale: A syndesmosis is a fibrous joint in which the two bony
surfaces are united by a ligament or membrane, allowing slight
movement (e.g., the distal tibiofibular joint). Gomphosis is a peg-in-
socket fibrous joint, and symphysis is a cartilaginous joint.
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 profound insulin deficiency, counter-regulatory
hormones stimulate gluconeogenesis (glucose formation pathways)
in the liver, contributing to severe hyperglycemia. Insulin deficiency
also leads to increased fat mobilization (lipolysis) and decreased
glucose uptake by cells, promoting ketone production and metabolic
acidosis.
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 from the posterior pituitary and
stimulates the let-down reflex (milk ejection) during breast-feeding.
Prolactin, which promotes milk production, is released from the
, anterior pituitary. Calcitonin regulates calcium, and incretins are
gut hormones.
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. Procallus
C. Calcium phosphate
D. Hydroxyapatite
Correct Answer: D. Hydroxyapatite
Rationale: Hydroxyapatite (calcium phosphate crystals) is the main
mineral component of bone, providing strength and rigidity.
Periosteum is a membrane covering bone, procallus is an early
stage of fracture healing, and calcium phosphate is the chemical
precursor.
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
