Chapter 29: Hematological and Oncological Disorders

The hematology section begins with sickle cell anemia, detailing the molecular basis of sickling, distinguishing among vaso-occlusive crises, splenic sequestration events, aplastic episodes, and hyperhemolytic crises, with emphasis on multimodal crisis management including aggressive hydration, oxygen therapy, analgesic administration, and emotional support for affected families. Iron deficiency anemia receives attention regarding supplementation protocols, dietary interventions, safe medication administration via z-track injection technique, and poison prevention counseling for families. Aplastic anemia management centers on recognizing pancytopenia manifestations, initiating immunosuppressive therapies, and preparing families for bone marrow transplantation procedures. Hemophilia and von Willebrand disease are explored through the lens of coagulation cascade dysfunction, clotting factor replacement strategies, desmopressin administration, and comprehensive bleeding precautions implemented across care settings. Beta-thalassemia major is reviewed with attention to severe anemia complications, chronic transfusion requirements, and iron chelation therapy to prevent organ damage. The oncology component addresses acute lymphoblastic leukemia with focus on bone marrow suppression consequences, infection and hemorrhage risks, and chemotherapy-related nursing responsibilities. Hodgkin's disease staging, Reed-Sternberg cell identification, and multimodal treatment approaches are presented alongside solid tumor pathology including Wilms' tumor with emphasis on avoiding abdominal manipulation, neuroblastoma with poor prognostic indicators, osteosarcoma requiring limb-sparing or amputation surgery, and pediatric brain tumors with intracranial pressure management. Throughout the chapter, nursing priorities encompass infection prevention in immunocompromised patients, hemorrhage surveillance, post-operative monitoring, cerebrospinal fluid leak identification, psychosocial support for children and families, prosthetic adaptation counseling, immunization guidance, genetic counseling resources, and community navigation assistance.
