6 Written questions

6 Multiple choice questions

  1. Hypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
    Allergen- what causes hypersensitivity reaction
  2. Rh & Type
    Prior to transfusions
  3. Oz
    IV & IVFs
    Possible intubation
    Epi
    Antihistamines
    Corticosteriods
  4. Detects hypersensitivity reactions
    *Puncture, intradermal, scratch, food allergy
    *Increased risk for anaphylactic response
  5. Immune complex (IgM & IgG)
    Circulating immune complexes deposited in body tissue
    Local inflammation & cell wall damage
    *persistent infections- edocarditism acute glomerulonephritis
    *Auto antibodies- rhematoid arthritis, systemic lupis
  6. Done if + indirect coombs or transfusion reaction occured

6 True/False questions

  1. Symptoms of AnaphylaxisOz
    IV & IVFs
    Possible intubation
    Epi
    Antihistamines
    Corticosteriods

          

  2. Immune Compex AssayDetects presense of circulation antibodies against RBC
    Normal to not have agglunation
    Part of cross & match
    (Blood & trasnfusion blood mixed-reaction??)

          

  3. Type IVCell mediated, delayed hypersensitivity
    T-cells sensitized to prev antigen
    Sensitized t-cells initiate inflammatory response
    Damage to surrounding tissue
    *TB skin test, contact dermatitis, graft vs host, transplant rejection

          

  4. Type ICytotoxic
    Immune system identifies a normal part of the body as foriegn
    Causes- hemolytic transfusion reactions, IgG or IgM to cell-bound antigen
    Types- Goodpastures, Pernicious anemia, myasthenia gravis, thrombocytopenia

          

  5. Classification of Hypersensitivity ReactionsHypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
    Allergen- what causes hypersensitivity reaction

          

  6. Altered Immune ResponseHypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
    Allergen- what causes hypersensitivity reaction
