NUR 254 CHAP 38 QUESTIONS WITH VERIFIED
ANSWERS .
Allergy,,,ANS,-
An,inappropriate,,often,harmful,response,of,the,immune,system,to,normally,harmless,substances,
Hypersensitive,reaction,to,an,allergen,initiated,by,immunologic,mechanisms,that,is,usually,mediated,by
,IgE,antibodies
Allergen,,,ANS,-the,substance,that,causes,the,allergic,response
Atopy,,,ANS,-
refers,to,the,allergic,reactions,characterized,by,IgE,antibody,action,and,a,genetic,predisposition
Immunoglobulins,and,Allergic,Response,,,ANS,-
Antibodies,(IgE,,IgD,,IgG,,IgM,,and,IgA),react,with,specific,effector,cells,and,molecules,and,function,to,p
rotect,the,body
IgE,antibodies,are,involved,in,allergic,disorders.
IgE,molecules,bind,to,an,allergen,and,trigger,mast,cells,or,basophils.
These,cells,then,release,chemical,mediators,such,as,histamine,,serotonin,,kinins,,SRS-
A,,and,neutrophil,factor.,
These,chemical,substances,cause,the,reactions,seen,in,allergic,response.
Allergic,Reaction,,,ANS,-
Allergen,triggers,the,B,cell,to,make,IgE,antibody,,which,attaches,to,the,mast,cell.,When,that,allergen,re
appears,,it,binds,to,the,IgE,and,triggers,the,mast,cell,to,release,its,chemicals.
Chemical,Mediators,,,ANS,-Primary
Histamine
Eosinophil,chemotactic,factor,of,anaphylaxis
Platelet-activating,factor
Prostaglandins
Secondary
, Leukotrienes
Bradykinin
Serotonin
False
An,antibody,,not,an,antigen,,is,a,protein,substance,developed,by,the,body,in,response,to,and,interactin
g,with,a,specific,antigen,,not,antibody.,,,ANS,-Is,the,following,statement,true,or,false?
An,antigen,is,a,protein,substance,developed,by,the,body,in,response,to,and,interacting,with,a,specific,a
ntibody.
Hypersensitivity,,,ANS,-A,reflection,of,excessive,or,aberrant,immune,response
Sensitization:,initiates,the,buildup,of,antibodies,
Types,of,hypersensitivity,reactions:
Anaphylactic:,type,I
Cytotoxic:,type,II,
Immune,complex:,type,III
Delayed-type:,type,IV
Management,of,Patients,With,Allergic,Disorders,,,ANS,-
History,and,manifestations;,comprehensive,allergy,history
Diagnostic,tests
CBC:,eosinophil,count
Total,serum,IgE
Skin,tests:,note,precautions!
Screening,procedures
Medication,,,ANS,-Oxygen,,if,respiratory,assistance,is,needed
Epinephrine,used,for,anaphylactic,reactions,
