The flashcards below were created by user julianne.elizabeth on FreezingBlue Flashcards. What would you like to do?


  1. Name the Lymphoid Tissues
    • Thymus
    • Bone Marrow
    • Spleen
    • Lymph Nodes
  2. What are Lymphomas?
    • Overgrowth of Lymphoid tissues due to cancerous changes
    • Two types are hodgkins and non-hodgkins lymphoma
  3. What differentiates Hodgkins from Non-Hodgkins Lymphoma
    • Hodgkins nodules are individualized and spread in an organized fashion
    • Hodgkin nodules have Reed Steinburg Cells
    • Non-Hodgkins spreads rapidly and randomly. No Reed Steinburg cells
  4. What are the S/S of Hodgkin's Lymphoma?
    • Enlarged lymph nodes in cervical, mediastinal or supraclavicular areas (palpable, painless, rubbery and freely movable)
    • These englarged lymph nodes may become tender with alcohol consumption
    • Fatigue
    • Fever
    • Night Sweats
    • Presence of Reed Steinberg cells in nodules
    • Nodules spread in a chain of lymph nodes in an organized fashion
    • More common in teens and young adults, then in older adults >50y/o
  5. How are Reed Steinburg cells distinguished?
    Giant cells with two nuclei upon biopsy
  6. What are the causes of HL?
    • Cause is unknown, but it may be viral in origin
    • Often occurs regardless of risk factors (epstein bar, HIV, genetics, bone marrow transplantation)
  7. How is HL treated?
    • It is one of the most treatable types of cancer
    • External radiation for stages I and II
    • Combo chemo stages III and IV
  8. What is NHL?
    • Non Hodgkin's Lymphoma
    • Most commonly, there is an infiltration with malignant B cells of the lymph system
    • The cause is unknown, more common in older adults
    • May be indolent (slow growing) or aggressive and systemic
    • Does not Spread in an organized fashion
    • No Reed Steinberg Cells
  9. What are the S/S of NHL?
    • May be asymptomatic
    • Lympadenopathy (swollen lymph nodes)
  10. What is the treatment for NHL?
    • Radiation therapy, chemo or both
    • Stem cell transplant may be an option for recurrent NHL
  11. What are Leukemias?
    • Replacement of Bone marrow with malignant immature WBCs
    • They are named according to the cell they affect and whether they are acute or chronic
    • The "blast cells" (immature, abnormal WBCs) grow wildly and replace infection fighting WBCs
    • These out-crowd all other cells and cross the blood brain barrier
  12. What are the types of Leukemias?
    • Acute Lymphocytic Leukemia (ALL): Effects mostly children
    • Chronic Lymphocytic Leukemia (CLL): effects mostly elderly
    • Acute Myelogenous Leukemia (AML): normally effect adults
    • Chronic Myelogenous Leukemia (CML): Shows philadelphia chromosome abnormalities
  13. What are the causes of Leukemias?
    • Exact Cause is unknown
    • Exposure to chemicals or radiation
    • Alteration in Chromosomes
    • Large amounts of antineoplastic drugs (chemo)
  14. What is the "miracle" treatment for AML?
    • Gleevac (Imatinib): protein kinase inhibitor that interferes with the growth of cancer cells
    • -95% remission!
  15. What are the S/S of Leukemias?
    • All related to bleeding, anemia and infections
    • Similar to the s/s of anemia
  16. What are some nursing diagnosis' for Leukemia?
    • Risk for Infection
    • Decreased tissue perfusion due to thrombocytopenia
    • Activity Intolerance
    • Alteration in Nutrition
    • Pain
    • Anxiety
  17. Describe ALL
    • 80% of cases occur in children 2-4 y/o and rarely occurs after age 15
    • Good response to chemo and radiation
    • Immature lymphoblasts
    • If untreated, 4-6 mo to live
    • If treated, 80-95% complete remission in children
  18. Describe AML
    • Immature myoblasts and WBC counts vary
    • Most common in adults from adolescence to 50 y/o
    • Client is usually asymptomatic except for fatigue and bleeding
    • If untreated, survival is 2-4 months
    • If patient <60 y/o, remission is 50-75%
    • 20% complete remission after 5 years
  19. Describe CLL
    • Most common in men 50-70 y/o
    • Increasing immature lymphocytes
    • Slow growth within lymph nodes, bone marrow, liver and spleen
    • If caught early (because it's slow growing), it has a good prognosis
  20. Describe CML
    • Common men >45 y/o and elderly
    • Associated with radiation and presence of the Philadelphia chromosome (esp for radiation for prostate cancer)
    • Increase in number of immature myloblasts
  21. How is Leukemia Diagnosed?
    • CBC- elevated lymphocytes
    • Bone Marrow Aspiration
    • Coagulation studies- thrombocytopenia
    • Chromosomal Analysis- philadelphia chromosome
    • Monitor Serum electrolytes
  22. What are the nursing responsibilities for radiation?
    • MRI and CT done prior to therapy to determine location and size
    • Temporary tattoos mark the site of radiation
    • Promote exercise to combat fatigue
    • Enhance Nutrition
    • Promote Sleep habits
    • Pain control
  23. What are some side effects of radiation?
    • Fatigue
    • Skin changes
    • Firmness of breast
    • Decreased weight

  27. What is Tumor Lysis Syndrome?
    • This is an emergency!!
    • During rapid tumor breakdown, large numbers of cells are killed rapidly, spilling potassium and metabolic bi-products into the blood

    • Roll the vial DO NOT SHAKE
    • It takes 2-8 weeks for HCT levels to increase
    • Monitor Iron labs, may need suppliments
  30. What is Filgrastim (Neupogen)?
    • A WBC stimualtor. ┬áIt is a granulocyte stimulating factor from human DNA
    • It promotes growth of neutrophils and enhances function of mature neutrophils
    • Usually given at an office appointment, often after chemo
    • 1mcg/kg/day up to 6 consecutive days IV or Subcut

    • It must be refrigerated and DO NOT SHAKE
    • Teach infection control
  31. Describe Neutropenic Precautions
    • Absolute neutropenia is <1,00 or an ANC of <1
    • HANDWASHING is still the most important!
    • Often called reverse isolation
    • No sick staff, no standing water, no uncooked food or fresh fruits/veg and no flowers
    • This has serious psychosocial implications for the patient
    • ASSESS for infection without the fever, due to low neutrophil count
  32. What are some side effects of chemo that the nurse needs to teach and care for?
    • Hair loss and skin changes
    • Fatigue
    • Reproductive issues
    • stomatitis/mucositis

    • *Skilled emotional support
  33. Describe the different kinds of bone marrow transplants
    • Allogenic Transplant: transplant from a donor, usually a genetic match like a biological sibling
    • Autologous Transplant: stem cells removed from patient prior to treatment and replaced after treatment
    • Synergetic Transplant: stem cells created in a lab
