Final answer:
The nurse should identify that itching, flushing of the face, anxiety, and urticaria are manifestations of a Type I hypersensitivity allergic reaction. These reactions can be localized such as in eczema or systemic as in anaphylaxis. Management varies from simple moisturizers and creams to emergency treatment with epinephrine for anaphylaxis.
Step-by-step explanation:
The nurse should identify that itching, flushing of the face, anxiety, and urticaria are manifestations of an allergic reaction, more specifically, a Type I hypersensitivity reaction. This reaction can range from mild forms, such as eczema, which involves dry, itchy patches of skin, to more severe reactions, such as anaphylaxis. Type I hypersensitivity reactions are often triggered by environmental allergens or foods, such as peanuts and shellfish, and can cause symptoms like itching, hives, and flushing, as well as more serious symptoms like difficulty breathing and a drop in blood pressure in severe cases. Localized symptoms, including the skin manifestations mentioned, can be managed with treatments like moisturizers, corticosteroid creams, and immunosuppressants. However, anaphylactic reactions require immediate medical attention and usually involve administration of epinephrine. Allergists may conduct skin testing to identify specific allergens that trigger the patient's hypersensitivity reactions.
