CHAPTER 33 part 2 Flashcards
ABNORMAL HEIGHTENED REACTION to a stimulus of any kind
hypersensitivity
what are the type of hypersensitivity
anaphylactic reaction
cytotoxic reaction
immune complex reaction
delayed reaction
the most severe type of hypersensitivity
anaphylactic reaction
a type of hypersensitivity that ‘‘it is characterized by VASODILATION, increased capillary permeability, SMOOTH MUSCLE CONTRACTION, and eosinophilia’’
anaphylactic reaction
type of hypersensitivity: involves BINDING EITHER THE LGG OR LGM ANTIBODY TO A CELL BOUND ANTIGEN, that may lead to eventual cell and tissue damage
cytotoxic reaction
swelling is under the skin instead of the surface (usually on the face)
angioedema
the REACTION IS THE RESULT OF MISTAKEN IDENTITY when the system identifies a normal constituent of the body as foreign
cytotoxic reaction
IgG + Igm =
complement system
it is marked as by ACUTE INFLAMMATION resulting from formation and DEPOSITION OF IMMUNE REFLEXES
immune complex reaction
occurs 1 to 3 days after exposure to an antigen
delayed reaction
what are common symptoms in delayed reaction
erythema
itching
in allergy, the eosinophil count in cbc is ???
increased
what is the usually the FIRST SKIN TEST BEFORE DOING OTHER PROCEDURE TO MINIMIZE ALLERGIC REACTION
prick test
eosinophil are also responsible for fighting ______ infection
parasitic
what type of reaction: asthma, allergic rhinitis, dermatitis
atopic
what type of reaction: lack of genetic development, LATEX
nonatopic
this medication is used for anaphylactic reactions
epinephrine
this drugs works by REVERSING THE EFFECTS OF HISTAMINE
epinephrine
mild, moderate, severe SYTEMIC REACTIONS
anaphylaxis
the reddish color of the skin because of vasodilation
flushing
severe itchiness, bumps on the skin; also called as HIVES
urticaria
swelling of the face
angioedema
what is the common drug cause of anaphylactic reaction
antibiotics: penicillin
hay fever
allergic rhinitis
a COMMON RESPIRATORY ALLERGY presumed to be mediated by a TYPE I hypersensitivity
allergic rhinitis
percentage of adults that is affected by allergic rhinitis
12%
allergic reaction to natural rubber proteins
lateX allergy
epinephrine is given sc, im, id?
subuctaneously
