Pathophysiology | Comprehensive Review Questions, Answers &
Rationales | LATEST UPDATE THIS YEAR PDF
Summary
A comprehensive NR507 Advanced Pathophysiology final exam review covering major
disease mechanisms, altered physiology, clinical manifestations, complications, and
pathophysiologic reasoning. Includes correct answers and concise rationales for focused
preparation.
Overview
This study guide emphasizes understanding why diseases occur, how they affect body systems,
and how pathophysiologic changes produce clinical findings. Questions are written in an
exam-style format to support comprehensive final-exam preparation.

,1.
A patient develops fever, localized swelling, erythema, and increased warmth after tissue
injury. Which physiologic process is primarily responsible for these acute inflammatory
findings?
A. Reduced vascular permeability
B. ✓ Vasodilation and increased vascular permeability
C. Suppression of leukocyte migration
D. Decreased release of inflammatory mediators
Rationale: Acute inflammation involves vasodilation and increased vascular permeability,
allowing plasma proteins and leukocytes to move into injured tissues.
2.
Which inflammatory mediator is primarily associated with vasodilation and increased
vascular permeability during an acute inflammatory response?
A. Insulin
B. ✓ Histamine
C. Erythropoietin
D. Thyroxine
Rationale: Histamine released from mast cells promotes vasodilation and increases
vascular permeability during early inflammation.
,3.
A patient develops fever during an acute infection. Which mediator contributes significantly
to the elevation of the hypothalamic temperature set point?
A. Albumin
B. ✓ Prostaglandin E2
C. Hemoglobin
D. Insulin
Rationale: Cytokines stimulate production of prostaglandin E2 in the hypothalamus, raising
the temperature set point and producing fever.
4.
A patient has a chronic inflammatory disorder with persistent tissue injury and fibrosis.
Which cells are particularly important in chronic inflammation?
A. Platelets only
B. ✓ Macrophages and lymphocytes
C. Erythrocytes only
D. Osteocytes only
Rationale: Chronic inflammation commonly involves macrophages, lymphocytes, and
plasma cells and may result in ongoing tissue destruction and fibrosis.
5.
, A patient develops an immune response after exposure to a foreign antigen. Which cells are
responsible for producing antibodies?
A. Neutrophils
B. ✓ Plasma cells
C. Erythrocytes
D. Platelets
Rationale: Activated B lymphocytes differentiate into plasma cells, which produce antigen-
specific antibodies.
6.
Which immunoglobulin is primarily associated with immediate hypersensitivity reactions and
allergic responses?
A. IgA
B. IgG
C. ✓ IgE
D. IgM
Rationale: IgE binds to mast cells and basophils and plays a central role in type I
hypersensitivity reactions.
