  1. Medical-Surgical Nursing: An Integrated Approach, 2E Chapter 22 NURSING CARE OF THE CLIENT: IMMUNE SYSTEM

  2. Immunity • The body’s ability to protect itself from foreign agents or organisms.

  3. Organs of the Immune System • Classified as primary or peripheral lymphoid organs. • Primary lymphoid organs are bone marrow and the thymus gland. • Peripheral lymphoid organs are lymph nodes, spleen, tonsils, appendix, Peyer’s patches of the small intestines, and the liver.

  4. Types of Immunity • Natural (innate). • Acquired (adaptive).

  5. Factors Influencing Immunity • Age. • Sex. • Nutritional Status. • Stress. • Treatment Modalities.

  6. Hypersensitive Immune Responses • Allergies. • Anaphylaxis. • Transfusion reactions. • Transplant rejection. • Latex allergy.

  7. Allergies • Allergic disorders are the result of a hypersensitivity (excessive reaction to a stimulus) of the immune system to allergens (a type of antigen commonly found in the environment).

  8. Anaphylaxis • A systemic reaction to allergens and the most serious type of allergic reaction. • Foods, drugs, hormones, insect bites, blood, and vaccines are all associated with anaphylactic reactions.

  9. Transfusion Reactions • Any client receiving blood products that are homologous or from a donor may develop a transfusion reaction. • Five types: febrile nonhemolytic; allergic urticarial; delayed hemolytic; acute hemolytic; and anaphylactic.

  10. Transplant Rejection • Even with the use of immunosuppressive medications, 10% to 15% of transplanted organs fail.

  11. Latex Allergy • Since 1987, when universal precautions (now called Standard Precautions) were mandated, exposure to latex by health care workers has dramatically increased. • By June, 1996, 28 latex-related deaths had been reported to the FDA.

  12. Autoimmune Diseases • Rheumatoid arthritis. • Systemic lupus erythematosus. • Myasthenia gravis.

  13. Rheumatoid Arthritis • A chronic, systemic autoimmune disease characterized by joint stiffness. • Affects 2.1 million people in the U.S. • Cause unknown, but genetic disposition suspected.

  14. Systemic Lupus Erythematosus • A chronic, progressive, incurable autoimmune disease affecting multiple body organs. • Characterized by periods of remission and exacerbation. • Occurs most commonly in women during their childbearing years, particularly in African Americans.

  15. Get adequate rest. Use stress-reduction techniques. Avoid exposure to sunlight; use sunscreen. Involve friends and family in care. Report fever, chills, anorexia, or symptom worsening to health care provider immediately. Never just stop taking medications. Contact the Lupus Foundation of America for information and support. Client Teaching for SystemicLupus Erythematosus

  16. Myasthenia Gravis • An autoimmune disease characterized by extreme muscle weakness and fatigue due to the body’s inability to transmit nerve impulses to voluntary muscles. • Clients must be carefully monitored for signs of respiratory distress and myasthenic or cholinergic crisis.
