1 Nursing of Adults with Medical & Surgical Conditions
Blood and Lymphatic Disorders

2 Blood and Lymphatic Disorders
Laboratory Tests RBC (erythrocytes) million/cu.mm Hemoglobin gm/100ml Hematocrit percent WBC ,000-10,000/mm Platelets , ,000/mm

3 Anemia Definition Disorder characterized by RBC and hemoglobin and hematocrit levels below normal range Causes delivery of insufficient amounts of oxygen to tissues and cells

4 Anemia Types Blood loss (hemorrhage)
Impaired production of RBC’s (bone marrow depression) Increased destruction of RBC’s (hemolysis) Nutritional deficiencies (long term iron deficiency)

5 Anemia Signs & Symptoms Insomnia Anorexia Cardiac dilation Pallor
Disorientation Dyspepsia Dyspnea Exertional dyspnea Fatigue Headache Insomnia Pallor Palpitation Shortness of breath Systolic murmur Tachycardia Vertigo

6 Hypovolemic Anemia Etiology/Pathophysiology
Abnormally low circulating blood volume due to blood loss 500 ml loss can be tolerated 1000 ml loss can be severe complications Severity and signs and symptoms depend on how rapid the blood is lost

7 Hypovolemic Anemia Signs & Symptoms Weakness Stupor Irritability
Pale, cool, moist skin Hypotension Tachycardia (rapid, weak, thready pulse) Hypothermia Hemoglobin less than 10 gm/100ml Hematocrit less than 40 % H&H may not drop for several hours after blood loss

8 Hypovolemic Anemia Treatment Control bleeding Treat shock
O2, elevate lower extremities, keep warm Replace fluid blood transfusion, plasma, dextran, lactaed ringers Monitor vital signs

9 Pernicious Anemia Etiology/Pathophysiology
Absence of the intrinsic factor Intrinsic factor is essential for the absorption of vitamin B12 Deficiency of vitamin B12 affects growth and maturity of all body cells RBC’s in the bone marrow don’t mature RBC membrane ruptures easily Vitamin B12 is also related to nerve myelination may cause progressive demyelination and degeneration of nerves and white matter

10 Pernicious Anemia Signs & Symptoms Extreme weakness Dyspnea Fever
Hypoxia Weight loss Jaundice (destruction of RBC’s) Pallor GI complaints

11 Pernicious Anemia Dysphagia Sore, burning tongue Neurological symptoms
Smooth and erythematous Neurological symptoms tingling of the hands and feet disorientation personality changes behavior problems partial or total paralysis

12 Pernicious Anemia Treatment Vitamin B12 (cyanocobalamin) 1000 units
daily for 1 week weekly for 1 month monthly for life Folic acid supplement Iron replacement RBC transfusion for severe anemia Diet high protein, vitamins, and minerals

13 Aplastic Anemia Etiology/Pathophysiology
Decrease of bone marrow function RBC production Primary congenital Secondary viral invasion medications chemicals radiation chemotherapy

14 Aplastic Anemia Signs & Symptoms Pancytopenic
all three major blood elements from the bone marrow are decreased (RBC, WBC, & Platelets) Repeated infections with high fevers Fatigue, weakness, malaise Dyspnea Palpitations Bleeding tendencies petechiae, ecchymossis, bleeding gums, epistaxis, GI & GU bleeds

15 Aplastic Anemia Treatment Identify & remove cause
Platelet transfusion for severe thrombocytopenia Splenectomy for hypersplenism Hypersplenism can cause destruction of platelets Steroids and androgens stimulate bone marrow Antithymocyte globulin stimulates bone marrow Bone marrow transplant

16 Iron Deficiency Anemia
Etiology/Pathophysiology RBC’s contain decreased levels of hemoglobin Excessive iron loss caused by chronic bleeding; intestinal, uterine, gastric

17 Iron Deficiency Anemia
Signs & Symptoms Pallor Fatigue Weakness Shortness of breath Angina S/S of heart failure Glossitis Pagophagia (desire to eat ice, clay, starches) Headache Paresthesia Burning tongue

18 Iron Deficiency Anemia
Treatment Ferrous Sulfate 900 mg daily Oral or injection (z-tract) Ascorbic acid enhances absorption of iron Diet high in iron Organ meats liver, kidney, heart, tongue Muscle meats (esp dark meat from poultry) Fish Eggs Green leafy vegetables Whole grains Dried beans Iron Deficiency Anemia

19 Sickle Cell Anemia Etiology/Pathophysiology
Most common genetic disorder in the U.S. Occurs predominantly in African Americans 1out of 10 have trait; 1 out of 500 have disease An abnormal, crescent shaped RBC contains hemoglobin S (Hg-S) Severe, chronic, incurable condition Disease Homozygous has two Hg-S genes; one from each parent Trait Heterozygous has one Hg-S gene from one parent and one Hg-A gene from the other parent Sickle Cell Anemia

20 Sickle Cell Anemia Signs & Symptoms Precipitating Factors
Dehydration Change in oxygen tension in the body infection, overexertion, cold, alcohol, smoking Loss of appetite Irritability Weakness Abdominal enlargement pooling of blood in the liver, spleen and other organs Join and back pain Edema of extremities

21 Sickle Cell Anemia Treatment No specific treatment Oxygen Rest Fluids
Alleviate symptoms Oxygen Rest Fluids oral and IV Analgesics Bone marrow transplant Experimental

22 Agranulocytosis Etiology/Pathophysiology
Severe reduction in the number of granulocytes (basophils, eosinophils, & neutrophils) WBC less than 200/mm3 Medications analgesics, antibiotics, antiepileptics, antihistamines, antineoplastic agents, antithyroid drugs, diuretics, phenothiazides, sulfonamides Chemotherapy Radiation Neoplastic disease Viral and bacterial infections

23 Agranulocytosis Signs & Symptoms S/S of infection
fever, chills, headache, fatigue Ulcerations of mucous membranes Bronchial pneumonia Urinary tract infection

24 Agranulocytosis Treatment
Identify and remove cause of bone marrow depression Prevent or treat infections Meticulous handwashing Strict asepsis

25 Leukemia Etiololgy/Pathophysiology
Malignant disorder of the hematopoietic system Excess leukocytes accumulate in the bone marrow and lymph nodes bone marrow produces immature cells Cause unknown Possible causes include genetic, virus, exposure to radiation, or chemotherapy Classification Acute or Chronic Proliferating cells (lymphocytic, monocytic, etc.)

26 Leukemia Signs & Symptoms Anemia Thrombocytopenia Leukopenia
pallor, fatigue, malaise Thrombocytopenia petechiae, epistaxis, bruising, occult blood Leukopenia fever, upper resp. infections, Enlarged lymph nodes Splenomegaly

27 Leukemia Treatment Chemotherapy Radiation Bone marrow transplant
Medications Leukeran hydroxyurea corticosteroids Cytoxan

28 Thrombocytopenia Etiology/Pathophysiology
Abnormal hematological condition in which the number of platelets is reduced below 100,000 mm3 Decreased production aplastic anemia, leukemia, tumors, chemotherapy Decreased survival antibody destruction, infection, viral invasion

29 Thrombocytopenia Signs & Symptoms Petechiae Ecchymoses
Platelets below 100,000 bleeding mucous membranes bleeding internal organs Platelets below 20,000 serious bleeding risks

30 Thrombocytopenia Treatment Corticosteriod therapy Splenectomy
Gamma globulin Immunosuppressive drugs Platelet transfusions Avoid trauma

31 Hemophilia Etiology/Pathophysiology
Hereditary coagulation disorder, characterized by a disturbance of clotting factor Hemophilia A most common Factor VIII is absent Hemophilia B Deficiency of Factor IX X-linked hereditary trait affects mainly males females are carriers

32 Hemophilia Signs & Symptoms Internal & external bleeding Hemarthrosis
bleeding into the joint; esp knees, ankles, and elbow Excessive blood loss from small cuts and dental procedures

33 Hemophilia Treatment Minimize bleeding Relieve pain Transfusions
avoid trauma Relieve pain No aspirin Transfusions Factor VIII or IX concentrate human-derived products can be treated to inactivate viruses Cryoprecipitate (rich in factor VIII) human-derived product Manufactured factor VIII or IX

34 von Willebrand’s Disease
Etiology/Pathophysiology Inherited bleeding disorder characterized by abnormally slow coagulation of blood and spontaneous episodes of GI bleeding, epistaxis, and gingival bleeding Mild deficiency of factor VIII Common during Postpartum Menorrhagia Post operative Post truama Similar to hemophilia; not limited to males

35 von Willebrand’s Disease
Treatment Cryoprecipitate Fibrinogen Fresh plasma Desmopressin (DDAVP) Synthetic of the human antiduiuretic hormone, vasopressin Causes an increase in factor VIII release from storage sites in the body Same nursing interventions as for hemophilia

36 Disseminated Intravascular Coagulation (DIC)
Etiology/Pathophysiology Overstimulation of clotting and anticlotting processes in response to disease or injury Septicemia Obstetrical complications Malignancies Tissue trauma Transfusion reaction Burns Shock Snake bites

37 Disseminated Intravascular Coagulation (DIC)
Primary disorder initiates generalized intravascular clotting, which overtimulates fibrinolytic mechanisms The hypercoagulability is followed by a deficiency in clotting factors with subsequent hypocoagulability and hemorrhaging

38 Disseminated Intravascular Coagulation (DIC)
Signs & Symptoms Bleeding Mucous membranes Venipuncture sites Surgical sites GI & GU tracts All orifices Dyspnea Hemoptysis Diaphoresis Cold, mottled digits Purpura on the chest and abdomen Petechiae

39 Disseminated Intravascular Coagulation (DIC)
Treatment Treat underlying cause Cryoprecipitate Heparin Protect from bleeding and trauma

40 Multiple Myeloma Etiology/Pathophysiology
Malignant neoplastic immunodeficiency disease of the bone marrow Tumor, composed of plasma cells, destroys osseous tissue Bone marrow becomes overcrowded and unable to produce erythrocytes, platelets, and leukocytes Onset is gradual and insidious

41 Multiple Myeloma Signs & Symptoms Bone pain Pathological fractures
Ribs, spine, and pelvis Pathological fractures Infection Anemia Bleeding Hypercalcemia Calcium and phosphorus drain from bones Renal failure Myeloma protein causes kidney damage Destruction of cells causes hyperuricemia

42 Multiple Myeloma Treatment Symptomatic; not curable Radiation
