6 Multiple choice questions

  1. IgE mediated hypersensitivity
    An allergen interacts with IgE bound to mast cells
    Histamine released
    If its potent-sytemic reactions
  2. Type I- anaphylactic
    Type II- Cytotoxic
    Type III- immune complex-mediated
    Type IV- Delayed
    Latex
    *Or immediate, delayed, anaphylactic, contact
  3. Hypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
    Allergen- what causes hypersensitivity reaction
  4. Sense of foreboding

    Types- Goodpastures, Pernicious anemia, myasthenia gravis, thrombocytopenia

6 True/False questions

  1. Skin TestDetects hypersensitivity reactions
    *Puncture, intradermal, scratch, food allergy
    *Increased risk for anaphylactic response

          

  2. Altered Immune ResponseHyper-responsivenes (allergies, aunto-immune DO, Reaction to organ/tissue transplant)
    Impaired Immune Response (AIDS, HIV, Immunodeficieny DO)

          

  3. Tx of AnaphylaxisOz
    IV & IVFs
    Possible intubation
    Epi
    Antihistamines
    Corticosteriods

          

  4. Indirect Coombs TestDetects presense of circulation antibodies against RBC
    Normal to not have agglunation
    Part of cross & match
    (Blood & trasnfusion blood mixed-reaction??)

          

  5. AnaphylaxisOz
    IV & IVFs
    Possible intubation
    Epi
    Antihistamines
    Corticosteriods

          

  6. Type IVCell mediated, delayed hypersensitivity
    T-cells sensitized to prev antigen
    Sensitized t-cells initiate inflammatory response
