edapt week 1
Immediate hypersensitivity is mediated by IgE antibodies, which result in an allergy,
anaphylaxis, or atopic disease. The NP should expect the client to have a type 1
hypersensitivity to recent medication use, which can include these immediate reactions as
clinical manifestations: urticaria, wheezing, vomiting, and diaphoresis.
Hypertension and bradycardia are not associated with immediate hypersensitivity reactions.
Clinical manifestations of hypersensitivity
Mast Cells
Mast cells are the primary effector cells and responsible for initiating and mediating type 1
hypersensitivity reactions. Characterized by the rapid release of proinflammatory mediators like
histamine, leukotrienes, and cytokines in response to allergen exposure, mast cells are the
primary effector cells responsible for initiating and mediating type 1 hypersensitivity reactions.
Type III
Immune complexes. Type 3 hypersensitivity reactions involve the formation of immune
complexes that can deposit in tissues, leading to complement activation and inflammation. This
process can cause tissue damage and is associated with systemic lupus erythematosus (SLE) and
serum sickness.
Type 1 reactions are mediated by IgE antibodies, and type 2 are mediated by IgG or IgM
antibodies. Type 4 reactions are activated by T-helper cells.
onset time, eczema, dog, outside, SOB, wheezing
Allergic rhinitis attacks are related to ongoing exposure to specific offending agents. The
strongest risk factor for developing asthma is a history of atopic disease (the client has eczema,
a form of atopic dermatitis). Environmental factors and allergens—such as high humidity, cold,
dry weather, house dust mites, pet fur, and pollen—can place a client at risk for a new diagnosis
of allergic asthma.
With prior exposure to allergens, Camille was sensitized. Chronic exposure to allergens
mediated IgE antibodies to attach to sensitized cells, and with further exposure, IgE caused
sensitized cells to degranulate. When degranulation occurs, inflammatory mediators like
histamine, leukotrienes, and prostaglandins are released to produce several effects on the body,
such as shortness of breath and wheezing. Constriction of bronchial smooth muscle also occurs,
