A client is being given cytokines to stimulate the immune system. What response should the nurse expect from this drug?
Standard Text: Select all that apply.
1. Some cytokines will kill foreign organisms in the body.
2. The client's inflammatory response will be stimulated.
3. The client's immune system will be taken over by the cytokines.
4. The client's lymphatic system will shut down.
5. There will be fewer white blood cells in the client's blood.
Correct Answer: 1,2
Rationale 1: Some cytokines kill pathogens directly.
Rationale 2: Some cytokines act to stimulate the inflammatory response.
Rationale 3: Cytokines are a part of the immune system and do not "take over."
Rationale 4: The lymphatic system is part of the immune system that is being stimulated.
Rationale 5: The goal is to stimulate the immune response, which includes the white blood cells.
Global Rationale: Activated T cells produce huge amounts of cytokines, which are hormone-like proteins that regulate the intensity and duration of the immune response and mediate cell-to-cell communication. Some cytokines kill foreign organisms directly, whereas others induce inflammation or enhance the killing power of macrophages. Specific cytokines released by activated T cells include inter-leukins, gamma interferon, tumor necrosis factor (TNF), and perforin. Some cytokines are used therapeutically to stimulate the immune system. Small amounts of cytokines are also secreted by certain macrophages, B lymphocytes, mast cells, endothelial cells, and the stromal cells of the spleen, thymus, and bone marrow. The client's immune system will not shut down or be taken over by this process. The goal is to stimulate the immune system, which increases the number of white blood cells.
