1. In a focused review of acute inflammation, question 1 considers a distinct mechanism. Which
concept is best described as follows: rapid arteriolar dilation and increased venular permeability?
A) Histamine
B) Integrins
C) Neutrophils
D) Selectins
Correct Answer: Histamine
Rationale: Histamine is the best answer because it rapid arteriolar dilation and increased venular
permeability. Stored in mast-cell granules and released early after tissue injury; the distinction
matters when interpreting acute inflammation. Unlike Integrins, Neutrophils, this choice directly
matches the mechanism in the stem rather than another feature of the same topic.
2. When examining acute inflammation, question 2 considers a distinct mechanism. Which concept
is best described as follows: increases vascular permeability and produces inflammatory pain?
A) Leukotriene B4
B) Bradykinin
C) Prostaglandin E2
D) Integrins
Correct Answer: Bradykinin
Rationale: Bradykinin is the best answer because it increases vascular permeability and produces
inflammatory pain. Generated through the kallikrein–kinin pathway; the distinction matters when
interpreting acute inflammation. Unlike Leukotriene B4, Prostaglandin E2, this choice directly
matches the mechanism in the stem rather than another feature of the same topic.
3. Within the framework of acute inflammation, question 3 considers a distinct mechanism. Which
concept is best described as follows: contributes to fever and sensitizes pain receptors?
A) C5a
B) Histamine
C) Prostaglandin E2
D) Selectins
,Correct Answer: Prostaglandin E2
Rationale: Prostaglandin E2 is the best answer because it contributes to fever and sensitizes pain
receptors. Synthesized from arachidonic acid through cyclooxygenase activity; the distinction
matters when interpreting acute inflammation. Unlike C5a, Histamine, this choice directly matches
the mechanism in the stem rather than another feature of the same topic.
4. In an advanced discussion of acute inflammation, question 4 considers a distinct mechanism.
Which concept is best described as follows: potently attracts and activates neutrophils?
A) Histamine
B) Diapedesis
C) Prostaglandin E2
D) Leukotriene B4
Correct Answer: Leukotriene B4
Rationale: Leukotriene B4 is the best answer because it potently attracts and activates neutrophils.
Formed through the lipoxygenase pathway; the distinction matters when interpreting acute
inflammation. Unlike Histamine, Diapedesis, this choice directly matches the mechanism in the
stem rather than another feature of the same topic.
5. For a case involving acute inflammation, question 5 considers a distinct mechanism. Which
concept is best described as follows: promotes neutrophil chemotaxis and amplifies inflammation?
A) C5a
B) Prostaglandin E2
C) Leukotriene B4
D) Histamine
Correct Answer: C5a
Rationale: C5a is the best answer because it promotes neutrophil chemotaxis and amplifies
inflammation. Released during complement activation; the distinction matters when interpreting
acute inflammation. Unlike Prostaglandin E2, Leukotriene B4, this choice directly matches the
mechanism in the stem rather than another feature of the same topic.
6. While analyzing acute inflammation, question 6 considers a distinct mechanism. Which concept
is best described as follows: mediate initial leukocyte rolling along activated endothelium?
A) Integrins
B) Selectins
C) Histamine
,D) Bradykinin
Correct Answer: Selectins
Rationale: Selectins is the best answer because it mediate initial leukocyte rolling along activated
endothelium. Support weak transient adhesion before firm attachment; the distinction matters when
interpreting acute inflammation. Unlike Integrins, Histamine, this choice directly matches the
mechanism in the stem rather than another feature of the same topic.
7. In evaluating acute inflammation, question 7 considers a distinct mechanism. Which concept is
best described as follows: mediate firm leukocyte adhesion to vascular endothelium?
A) C5a
B) Macrophages
C) Integrins
D) Prostaglandin E2
Correct Answer: Integrins
Rationale: Integrins is the best answer because it mediate firm leukocyte adhesion to vascular
endothelium. Increase binding avidity after chemokine signaling; the distinction matters when
interpreting acute inflammation. Unlike C5a, Macrophages, this choice directly matches the
mechanism in the stem rather than another feature of the same topic.
8. During an assessment of acute inflammation, question 8 considers a distinct mechanism. Which
concept is best described as follows: describes leukocyte passage between endothelial cells into
tissue?
A) Leukotriene B4
B) Macrophages
C) Integrins
D) Diapedesis
Correct Answer: Diapedesis
Rationale: Diapedesis is the best answer because it describes leukocyte passage between
endothelial cells into tissue. Occurs after rolling and firm adhesion; the distinction matters when
interpreting acute inflammation. Unlike Leukotriene B4, Macrophages, this choice directly matches
the mechanism in the stem rather than another feature of the same topic.
9. In a teaching session about acute inflammation, question 9 considers a distinct mechanism.
Which concept is best described as follows: predominate early in many acute bacterial
inflammatory responses?
A) Neutrophils
, B) Bradykinin
C) Leukotriene B4
D) Integrins
Correct Answer: Neutrophils
Rationale: Neutrophils is the best answer because it predominate early in many acute bacterial
inflammatory responses. Rapidly migrate to sites of tissue injury and phagocytose microbes; the
distinction matters when interpreting acute inflammation. Unlike Bradykinin, Leukotriene B4, this
choice directly matches the mechanism in the stem rather than another feature of the same topic.
10. To distinguish mechanisms in acute inflammation, question 10 considers a distinct mechanism.
Which concept is best described as follows: remove debris and orchestrate later inflammation and
repair?
A) Bradykinin
B) Macrophages
C) Neutrophils
D) Selectins
Correct Answer: Macrophages
Rationale: Macrophages is the best answer because it remove debris and orchestrate later
inflammation and repair. Release cytokines and growth factors that shape tissue responses; the
distinction matters when interpreting acute inflammation. Unlike Bradykinin, Neutrophils, this choice
directly matches the mechanism in the stem rather than another feature of the same topic.
11. In a focused review of inflammatory mediators and repair, question 11 considers a distinct
mechanism. Which concept is best described as follows: promotes fever and endothelial activation
during inflammation?
A) C-reactive protein
B) Exudate
C) Interleukin-1
D) Tumor necrosis factor
Correct Answer: Interleukin-1
Rationale: Interleukin-1 is the best answer because it promotes fever and endothelial activation
during inflammation. Is a major proinflammatory cytokine released by activated innate immune
cells; the distinction matters when interpreting inflammatory mediators and repair. Unlike C-reactive
