    Study Notes

    Cellular Regulation

    • Cellular regulation refers to the processes that control the growth and function of cells.

    Interrelated Concepts

    • Mobility, nutrition, perfusion, oxygenation, and immunity depend on proper cellular regulation.

    Childhood Cancers

    • Acute Myeloid Leukemia (AML): Cancer characterized by the rapid growth of abnormal myeloid cells in the bone marrow.
    • Acute Lymphocytic Leukemia (ALL): Cancer characterized by the rapid growth of abnormal lymphoid cells in the bone marrow.
    • Hodgkin Lymphoma: Cancer of the lymph nodes.
    • Non-Hodgkin Lymphoma: Cancer that originates in the lymphatic system.
    • Wilm’s Tumor: Cancer that affects the kidneys.
    • Osteosarcoma: Cancer of the bone.

    Clinical Manifestations of Childhood Cancers

    • Fatigue
    • Pallor
    • Weight Loss
    • Bruising
    • Unusual Bleeding
    • Recurrent Infections
    • Joint or Bone Pain
    • Weakness

    Nursing considerations for Childhood Cancers

    • Managing complications: infection, pain, anemia, bleeding, adverse effects of treatment.
    • Emotional support: Patients and families require emotional support throughout the treatment process.

    Treatment Modalities for Childhood Cancers

    • Chemotherapy: Using drugs to kill cancer cells.
    • Hematopoietic Stem Cell transplantation: Replacing damaged bone marrow with healthy stem cells.
    • Surgery: Removal of cancerous tissue or tumor.

    Sickle Cell Anemia (SCA)

    • A genetic blood disorder where abnormal hemoglobin (HbS) replaces normal hemoglobin.
    • Sickle-shaped red blood cells cause increased blood viscosity and obstruct blood flow, leading to tissue hypoxia, ischemia, and pain.
    • Sickle cell crises can occur when HbS clumps together, making blood more viscous.

    Nursing Care for SCA

    • Managing pain: Pain management is a crucial aspect of care.
    • Preventing infection: Patients with SCA are at increased risk for infections.
    • Hydration: Hydration is essential to thin the blood and prevent sickling.
    • Oxygen therapy: Oxygen can be administered during sickle cell crises to improve oxygenation.
    • Blood transfusions: Transfusions can be used to increase the number of normal red blood cells.
    • Hydroxyurea: This medication helps to reduce the number of sickle cells.

    Medications for SCA

    • Pain relievers: Opioids are often used for pain management.
    • Antibiotics: Antibiotics are used to prevent and treat infections.
    • Folic acid: Folic acid supplements are recommended to help with red blood cell production.

    Hemophilia A and B

    • Genetic bleeding disorders that cause difficulty controlling bleeding due to a deficiency in clotting factors.
    • Hemophilia A: Deficiency in clotting factor VIII.
    • Hemophilia B: Deficiency in clotting factor IX.
    • Von Willebrand Disease: A bleeding disorder caused by a deficiency or defect in Von Willebrand factor (VWF), which helps platelets to stick to the blood vessel walls.

    Thalassemia

    • Inherited blood disorder that reduces hemoglobin production.
    • Causes anemia because of:
      • Defective synthesis of hemoglobin.
      • Structurally impaired red blood cells.
      • Shortened lifespan of red blood cells.

    Idiopathic Thrombocytopenic Purpura (ITP)

    • Autoimmune disorder that causes the body to destroy its own platelets.
    • Platelets help blood to clot, so low platelet counts lead to easy bruising and bleeding.

    Other Blood Disorders

    • Iron deficiency anemia: Occurs when the body doesn't have enough iron to produce hemoglobin.
    • Lead exposure: Lead poisoning can disrupt the production of red blood cells, leading to anemia and other health problems.

    Interdisciplinary team in caring for children with alterations in cellular growth

    • Physicians: Diagnose and treat cancer.
    • Nurses: Provide direct patient care, monitor vital signs, administer medications, and educate patients and families.
    • Social workers: Provide support and counseling to patients and families.
    • Psychologists: Help to address the emotional and mental health needs of patients and families.
    • Pharmacists: Dispense medications and provide advice on medication safety.
    • Physical therapists: Help patients with physical rehabilitation.
    • Occupational therapists: Help patients with activities of daily living.
    • Nutritionists: Provide nutritional counseling to patients and families.
