6 Written questions

6 Multiple choice questions

  1. Hyper-responsivenes (allergies, aunto-immune DO, Reaction to organ/tissue transplant)
    Impaired Immune Response (AIDS, HIV, Immunodeficieny DO)
  2. Detects presense of circulation antibodies against RBC
    Normal to not have agglunation
    Part of cross & match
    (Blood & trasnfusion blood mixed-reaction??)
  3. Cytotoxic
    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
  4. Detects the presence of circulating immune complexes in type II hypersensitivity response
    Useful in autoimmune DO
  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. Detects high level of circulating eosinophils

6 True/False questions

  1. 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

          

  2. Type IIgE mediated hypersensitivity
    An allergen interacts with IgE bound to mast cells
    Histamine released
    If its potent-sytemic reactions

          

  3. AnaphylaxisOz
    IV & IVFs
    Possible intubation
    Epi
    Antihistamines
    Corticosteriods

          

  4. 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

          

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

          

  6. Hypersensitivity ReactionsHypersensitvity-Altered immune response to an antigen that causes harm to a person
    Allergy- Antigen is enviornmental or exogenous
