A nurse is educating a client who was recently diagnosed with cancer and tells the nurse they are worried about infertility following radiation treatment. Which of the following interventions should the nurse recommend?

Choice A reason:
Hay fever allergy, also known as allergic rhinitis, is primarily associated with the action of Immunoglobulin E (IgE) antibodies and not directly with T-cells. T-cells can contribute to the regulation of the immune response in allergies, but IgE is the main immunoglobulin involved in the typical symptoms of hay fever.

Choice B reason:
Anaphylaxis is a severe, potentially life-threatening allergic reaction that involves the release of large amounts of histamine and other chemicals from mast cells and basophils, often triggered by IgE antibodies. While T-cells can play a role in the sensitization phase of allergy, anaphylaxis itself is not directly caused by T-cells.

Choice C reason:
Transplant rejection is a process in which T-cells play a central role. When a transplant recipient's immune system recognizes the donated organ as foreign, T-cells can mediate the rejection by attacking the transplanted tissue, leading to its failure.

Choice D reason:
Bacterial phagocytosis is primarily the function of phagocytes like neutrophils and macrophages. T-cells are involved in the adaptive immune response and can activate phagocytes, but they do not directly perform phagocytosis.

Choice A reason:
Immunoglobulin G (IgG) is the most common type of antibody found in blood circulation and is involved in the body's immune response to fight infections. However, IgG is not typically associated with allergic reactions, which are immediate hypersensitivity reactions.

Choice B reason:
Immunoglobulin A (IgA) plays a critical role in mucosal immunity and is found in high concentrations in the mucous membranes, particularly those lining the respiratory passages and gastrointestinal tract. Like IgG, IgA is not primarily responsible for the allergic response seen in conditions such as seasonal allergies.

Choice C reason:
Immunoglobulin M (IgM) is usually the first antibody produced by the immune system when it detects an infection. IgM antibodies are larger and are involved in the primary immune response but are not the antibodies that mediate typical allergic reactions.

Choice D reason:
Immunoglobulin E (IgE) is the antibody that plays a central role in the pathophysiology of allergic diseases, including seasonal allergies. IgE antibodies are produced as a response to allergens and are responsible for the symptoms of an allergic reaction. An elevation in IgE levels typically indicates a positive result for an allergy test such as RAST.
