NR 507 WEEK 1- IMMUNOLOGY &
PATHOPHYSIOLOGY EXAM WITH ACCURATE
QUESTIONS AND A+ GRADED SOLUTIONS
2026
Neutrophils - correct answers-first responders
Type 1 hypersensitivity REACTION - correct
answers--IgE mediated
,-Ex: Asthma, allergic rhinitis, atopic dermatitis,
anaphylactic shock, urticaria, angioedema
LOCAL OR SYSTEMIC
Type 2 (Cytotoxic) hypersensitivity reactions
are mediated by - correct answers-IgG or IgM.
Sensitization - correct answers-Developing a
sensitivity to a substance that initially caused
no allergic reaction.
After the allergen is cleared, the remaining IgE
molecules will be bound by mast cells,
basophils, and eosinophils that contain
receptors for the IgE molecules.
Immediate degranulation - correct answers-
causes the release of inflammatory mediators
,such as histamine, leukotrienes, and
prostaglandins that results in vasodilation,
bronchial smooth muscle contraction, and
mucus production
Systemic reactions - correct answers-involve
basophil degranulation; they occur throughout
the body, can lead to anaphylactic shock, and
can be life-threatening EX. ALLERGIC ASTHMA
Type II hypersensitivity reaction - correct
answers--Cytotoxic
-Antibody attacks the antigen leading to lysis
(complement mediated)
-IgG & IgM are the principal antibodies involved
-Examples: hemolytic anemia,
thrombocytopenia
, Hapten - correct answers-small molecule that
has to bind to a larger molecule to form an
antigen
CAN CAUSE AN IMMUNE RESPONSE WHEN IT
ATTACHES TO A PROTEIN.
MACROPHAGES ROLE IN TYPE 11
HYPERSENSITIVITY - correct answers-primary
effector cells of Type II responses
Examples of Type II reactions - correct answers-
drug allergies, hemolytic anemia, blood
transfusion mismatch with resulting transfusion
reaction and Rh hemolytic disease.
