,CHAPTER 1: THE FOUNDATIONAL CONCEPTS OF CLINICAL PRACTICE
1. The characteristic, localized cardinal signs of acute inflammation include:
A) fever.
B) fatigue.
C) redness.
D) granuloma.
Correct Answer: C) redness.
Explanation: The classic localized cardinal signs of acute inflammation are
redness (rubor), heat (calor), swelling (tumor), pain (dolor), and loss of
function (functio laesa). Redness occurs due to vasodilation and increased
blood flow. Fever and fatigue are systemic signs, while granuloma formation
is characteristic of chronic inflammation.
2. The vascular, hemodynamic stage of acute inflammation is initiated by
momentary vasoconstriction followed by vasodilation that causes localized:
A) bleeding.
B) congestion.
C) pale skin.
D) coolness.
Correct Answer: B) congestion.
Explanation: Following momentary vasoconstriction, vasodilation occurs,
leading to increased blood flow and congestion (hyperemia). This results in
redness and warmth. The congestion is caused by the opening of arterioles
and capillaries in the inflamed region.
3. The Cellular stage of acute inflammation is marked by the movement of
leukocytes into the area. Which of the following cells arrives early in
great numbers?
A) Basophils
B) Lymphocytes
C) Neutrophils
D) Platelets
Correct Answer: C) Neutrophils.
, Explanation: Neutrophils are the first phagocytic cells to arrive at the
site of acute inflammation, typically within 6-12 hours. They are the most
abundant white blood cells and are essential for the early immune response.
4. The phagocytosis process involves three distinct steps. What is the initial
step in the process?
A) Engulfment
B) Intracellular killing
C) Antigen margination
D) Recognition and adherence
Correct Answer: D) Recognition and adherence.
Explanation: Phagocytosis occurs in three sequential steps: (1) Recognition
and adherence - the phagocyte identifies and attaches to the target;
(2) Engulfment - pseudopods surround and internalize the particle;
(3) Intracellular killing - phagosome fuses with lysosomes for destruction.
5. Which of the following mediators of inflammation causes increased capillary
permeability and pain?
A) Serotonin
B) Histamine
C) Bradykinin
D) Nitric oxide
Correct Answer: C) Bradykinin.
Explanation: Bradykinin is a potent inflammatory mediator that causes
increased vascular permeability, vasodilation, and pain (through stimulation
of pain nerve endings). While histamine and serotonin also increase capillary
permeability, bradykinin is uniquely associated with pain production.
6. Inflammatory exudates are a combination of several types. Which of the
following exudates is composed of enmeshed necrotic cells?
A) Serous
B) Fibrinous
C) Suppurative
D) Membranous
Correct Answer: C) Suppurative.
