,NUR 2063 Exam 1 Essentials of Pathophysiology Questions and
Answers | 2026/2027 | Rasmussen University
Q1. Which change is characteristic of an inflammatory response in
injured tissue?
A) Decreased blood flow
B) Reduced vascular permeability
C) Increased blood flow and vascular permeability
D) Immediate tissue regeneration
Correct Answer: C) Increased blood flow and vascular permeability
Rationale: Inflammation increases local blood flow and vascular
permeability, allowing fluid and immune components to move into the
affected tissue.
Q2. Which finding is most consistent with a partial-thickness burn?
A) Damage limited entirely to the epidermis
B) Blister formation with injury extending into the dermis
C) Full destruction of all skin layers with a dry, leathery appearance
D) Injury limited to subcutaneous tissue
Correct Answer: B) Blister formation with injury extending into the dermis
Rationale: Partial-thickness burns extend through the epidermis into part of
the dermis and commonly produce pain, redness, and blisters.
Q3. What is a major pathophysiologic concern immediately after a
significant burn injury?
A) Excessive bone formation
B) Increased circulating blood volume
C) Reduced capillary permeability
D) Fluid shifting from the intravascular space into injured tissues
Correct Answer: D) Fluid shifting from the intravascular space into injured
tissues
Rationale: Major burns increase vascular permeability, allowing plasma to
move into the interstitial space and causing significant fluid loss from the
circulation.
Q4. Which finding is most characteristic of osteoporosis?
, A) Increased bone density
B) Abnormal cartilage growth
C) Progressive loss of bone mass and increased fracture risk
D) Acute inflammation of synovial membranes
Correct Answer: B) Abnormal cartilage growth
Rationale: Osteoporosis involves reduced bone mass and deterioration of
bone structure, making bones more fragile and susceptible to fracture.
Q5. Which factor contributes most directly to osteoporosis?
A) Increased osteoblast activity
B) Excessive cartilage formation
C) Imbalance favoring bone resorption over bone formation
D) Increased joint-fluid production
Correct Answer: B) Imbalance favoring bone resorption over bone formation
Rationale: Osteoporosis develops when bone resorption exceeds bone
formation over time, resulting in reduced bone mass.
Q6. Which finding is most consistent with osteoarthritis?
A) Degeneration of articular cartilage
B) Systemic immune-complex deposition
C) Acute bone infection
D) Malignant transformation of cartilage cells
Correct Answer: A) Degeneration of articular cartilage
Rationale: Osteoarthritis is primarily associated with progressive
degeneration of articular cartilage and related changes in the joint.
Q7. Rheumatoid arthritis differs from osteoarthritis primarily
because rheumatoid arthritis involves:
A) Degeneration caused only by mechanical wear
B) An immune-mediated inflammatory process
C) Loss of bone caused only by aging
D) Direct injury to skeletal muscle
Correct Answer: B) An immune-mediated inflammatory process
Rationale: Rheumatoid arthritis is an autoimmune inflammatory disorder
that primarily targets synovial tissues, whereas osteoarthritis is primarily
degenerative.
