Hematologic & Immunologic Conditions Lisa Walsh Ph.D.,RN Northeastern University ABSN Program Lesson Objectives • Review basic anatomy and physiology of the hematologic system. • Differentiate normal and abnormal laboratory values of the complete blood count. • Apply the nursing process as a framework for hematologic and immunologic problems. • Differentiate major categories of anemia and treatment. • Prioritize nursing interventions in the administration of blood component therapy. • Apply the nursing process as a framework for hypersensitivity and autoimmune disorders. • Prioritize nursing interventions in allergic responses including anaphylaxis. • Prioritize nursing interventions in rheumatologic disorders. Hematologic System – Blood Cell Development ◦ Erythrocytes – Red Blood Cells ◦ Leukocytes – White Blood Cells ◦ Thrombocytes – Platelets ◦ Plasma – Fluid portion of blood ◦ Blood cells created in bone marrow, spleen and reticuloendothelial system ◦Hematologic Assessment Table 32-2, ◦ Health History ◦ Physical Assessment ◦ Diagnostic Evaluation ◦ https://medlineplus.gov/lab-tests/complete-blood-count-cbc/ Anemias table 33-1 ◦ Hypoproliferative (Defective RBC Production) ◦ Bleeding (RBC Loss) ◦ Hemolytic (RBC Destruction) ◦ Nursing Care: ◦ Assessment ◦ Education ◦ Transfusion Blood Product Administration Indications Prescription Consent American Red Cross Blood Transfusions Preparation Assessment (pre, during, & post Tx) Education RegisteredNurseRN Blood Transfusion Procedure Nursing | Reaction Types, Complications (Hemolytic/Febrile) Transfusion Complications ◦ Febrile nonhemolytic reaction ◦ Acute hemolytic reaction ◦ Allergic reaction ◦ Transfusion-Associated Circulatory Overload (TACO) ◦ Bacterial contamination ◦ Transfusion-Related Acute Lung Injury (TRALI) ◦ Delayed hemolytic reaction ◦ Disease acquisition ◦ Long-term transfusion therapy Coagulation Disorders ◦ Liver disease ◦ Antithrombin deficiency ◦ Vitamin K deficiency ◦ Protein C & S deficiency ◦ Complications of anticoagulant ◦ Activated protein C resistance therapy and factor V Leiden mutation ◦ Disseminated intravascular coagulation (DIC)** ◦ Thrombotic disorders ◦ Hyperhomocysteinemia ◦ Acquired thrombophilia ◦ Malignancy DIC – Sign of underlying disorder ◦ Triggers may include sepsis, trauma, shock, cancer, abruptio placentae, toxins, and allergic reactions ◦ Altered hemostasis mechanism causes massive clotting in microcirculation. As clotting factors are consumed, bleeding occurs. ◦ Treatment: treat underlying cause, correct tissue ischemia, replace fluids and electrolytes, maintain blood pressure, replace coagulation factors, use heparin or LMWH Hypersensitivity & Autoimmune -WBC Problems ◦Hypersensitivity Reaction: when the immune system has a harmful effect on the body ◦Autoimmune Disease: abnormal immune response to a antigen that is part of the human body ◦Immunopathology: the study of diseases that results from dysfunction of the immune system Immunity Assessment ◦ Health history ◦ Physical exam ◦ Bone marrow biopsy ◦ Humoral and cellular immunity tests ◦ Phagocytic cell function test ◦ Hypersensitivity tests ◦ Specific antigen–antibody tests ◦ HIV infection tests Allergy & Anaphylaxis ◦ Manifestation of tissue injury resulting from interaction between an antigen and an antibody ◦Body encounters allergens that are types of antigens ◦Body's defenses recognize antigens as foreign ◦Series of events occurs in an attempt to render the invaders harmless, destroy them, and remove them from the body Allergy Assessment: ◦History and manifestations; comprehensive allergy history ◦Diagnostic tests ◦CBC: eosinophil count ◦Total serum IgE ◦Skin tests: prick, scratch, and intradermal Anaphylaxis Mayo Clinic video ◦Mild, moderate, and severe systemic reactions ◦Symptoms are sudden in onset and progress in severity over minutes to hours ◦ Flushing ◦ Urticaria ◦ Angioedema ◦ Hypotention ◦ Bronchoconstriction ◦Common Causes; Refer to Chart 37-2 ◦ Antibiotics most common; penicillin Allergy & Asthma Network Rheumatic Disorders ◦ Autoimmune, degenerative, inflammatory, and systemic conditions ◦ Affect the joints, muscles, and soft tissues of the body ◦ Marked by periods of remission and exacerbation ◦ Classification ◦ Monoarticular or polyarticular ◦ Inflammatory or noninflammatory Three distinct characteristics: ◦Inflammation ◦Complex process resulting in pannus ◦Autoimmunity ◦Hallmark of rheumatologic disease ◦Body recognizes own tissue as foreign ◦Degeneration ◦Secondary process to inflammation Nursing Care: ◦Relief of pain and discomfort ◦Relief of fatigue ◦Increased mobility ◦Maintenance of self-care ◦Improved body image ◦Effective coping ◦Absence of complications Lesson Objectives • Review basic anatomy and physiology of the hematologic system. • Differentiate normal and abnormal laboratory values of the complete blood count. • Apply the nursing process as a framework for hematologic and immunologic problems. • Differentiate major categories of anemia and treatment. • Prioritize nursing interventions in the administration of blood component therapy. • Apply the nursing process as a framework for hypersensitivity and autoimmune disorders. • Prioritize nursing interventions in allergic responses including anaphylaxis. • Prioritize nursing interventions in rheumatologic disorders.
