What are the four types of hypersensitivity reactions? -CORRECTANSWER 1. Type 1:
Allergic/Anaphylactic/Atopic 2. Type 2: Cytotoxic 3. Type 3: Immune Complex 4. Type 4:
Delayed.
,What characterizes Type 1 hypersensitivity reactions? -CORRECTANSWER Rapid
release of proinflammatory mediators like histamine, leukotrienes, prostaglandins, and
cytokines in response to allergic exposure.
What are the physiological manifestations of Type 1 hypersensitivity reactions? -
CORRECTANSWER Vasodilation, bronchial smooth muscle contraction, and mucus
production.
What is the prototype disease for Type 1 hypersensitivity? -CORRECTANSWER
Anaphylaxis, Allergic Rhinitis, Asthma, Food Allergies.
What are the signs and symptoms of Anaphylaxis? -CORRECTANSWER Rapid onset;
difficulty breathing, hypotension, hives, wheezing, angioedema, and possibly shock.
What are the treatment options for Anaphylaxis? -CORRECTANSWER Epinephrine
(IM), airway management, oxygen and IV fluids, antihistamines, corticosteroids.
What is the mechanism behind Type 2 hypersensitivity reactions? -
CORRECTANSWER IgG or IgM antibodies target antigens on cells, leading to cell
destruction via complement activation or phagocytosis.

Heparin-induced thrombocytopenia (HIT) and hemolytic transfusion reactions.
What are the primary effector cells in Type 2 hypersensitivity reactions? -
CORRECTANSWER Macrophages.
What are the signs and symptoms of Type 2 hypersensitivity reactions? -
CORRECTANSWER Fatigue, pallor, jaundice, tachycardia, shortness of breath,
elevated bilirubin, low hemoglobin and hematocrit.

Autoimmune Hemolytic Anemia, Grave's Disease.
What is the pathophysiology of Type 3 hypersensitivity reactions? -CORRECTANSWER
Immune complex-mediated reactions.
What is the role of mast cells in Type 1 hypersensitivity reactions? -
CORRECTANSWER They are the primary effector cells responsible for initiating and
mediating the reactions.
