                                   1
                      Definitions
• Hematocrit:
   • Measure of packed cell volume of RBC expressed as a %
   • Women: 38-47%
   • Men: 40-54%
   Hemoglobin
   • Measurement of gas carrying capacity of RBC
   • Men: 13.5-18g/dl
   • Women: 12-16g/dl
   Neutropenia
   • abnormally low number of neutrophils in the blood
   • < 1500…normal 3000 – 7000mm³
   • Neutrophils, a type of white blood cell, help fight bacterial
     infections. Most abundant WBC
   • Side effects of medication, chemotherapy, viral infections



                                                                     2
                    Definitions
• Reticulocytes
   • Are young red cells just released from the bone marrow.
     The Retic count tells us how the marrow factory is doing.
   • Immature RBC’s, less than 1%

• Thrombocytopenia
   • Platelet counts are between 150,000-400,000ul
   • low platelets, below 100,000-150,000
   • Bleeding may occur

• ESR Erythrocyte sedimentation rate
   • Indicative of inflammation
   • Increased ESR is common during acute and chronic
     inflammatory reactions
   • Women: 1-20mm
   • Men: 1-15mm

                                                                 3
                      Anemias
• A deficiency in the number of RBC, quantity of HgB
  and the volume of HCT
• There is an abnormality with the structure or
  function or number of RBC’s
• Anemia is not a disease, it is a manifestation of a
  pathologic process.
   • primary hematological problems
   • secondary to defects in other body systems
• This can lead to hypoxia, a decrease in the oxygen
  carrying capacity of the blood.
• The clinical manifestations anemia are primarily
  caused by the body’s responses to tissue hypoxia.



                                                        4
   Clinical Manifestations of Anemia
• Mild Anemia
  • 10-14 Hgb.
  • Generally asymptomatic, symptoms can occur with disease
    or exertion
• Moderate Anemia
  • Hgb 6-10
  • Cardiopulmonary symptoms may be increased and may be
    associated with rest as well as activity.
  • Palpitations, fatigue, dyspnea, & diaphoresis
• Severe Anemia
  • Hgb less than 6.
  • Symptoms involve many body systems.
  • It is caused by severe tissue hypoxia. Pallor, chronic fatigue,
    chills, ↑ HR, murmurs, can lead to CHF, angina, MI

                                                                      5
         Clinical Manifestations with Anemia
• Cardiac effects when Hgb is too low.
    • Ischemia
    • Tissue hypoxia
    • Chronic fatigue
• Sensitivity to cold
    • The blood is shunted to the major organs
•   Pallor – reduced hemoglobin and blood flow to skin
•   Decreased CO leads to Increased HR
•   Murmurs due to lack of blood volume
•   CHF can occur to the increased strain on the heart.
    In severe cases, angina and MI can occur.



                                                          6
       Nursing and Gerontological Considerations
• Anemia is common in older adults
   • Anemia of chronic disease
   • Nutritional deficiencies
• Signs and symptoms unrecognized
   • Attribute them to the normal aging process
   • Common signs and symptoms include: pallor, confusion, ataxia,
     fatigue, worsening angina.
• Nursing Implementation:
   •   Dietary and lifestyle changes
   •   Blood products
   •   Blood transfusions
   •   Drug therapy – Erythropoietin (Procrit, Epogen)
   •   Oxygen therapy



                                                                     7
  Nutrients Needed for Erythropoiesis
• Vitamin B12
   • RBC maturation – red meats
• Folic Acid
   • RBC maturation – Green leafy vegetables, liver, meat, fish
     legumes, whole grains
• Iron
   • Hemoglobin synthesis – liver and muscle meats, eggs
• Vitamin B6
   • Hemoglobin synthesis – meats, legumes, potatoes
• Amino Acids
   • Synthesis of nucleoproteins –eggs, meat, milk, poultry, fish
• Vitamin C
   • Aids in iron absorption – citrus fruits, green leafy veggies,
     strawberries, cantaloupe

                                                                     8
Anemia’s Related to Decreased Erythrocyte Production
• Iron Deficiency Anemia
   • Found world wide due to poor nutrition
      • Inadequate dietary intake
          • Iron is obtained from food and dietary supplements
          • If you eat 12 mg. of iron per day only 10% is absorbed
      • Malabsorbtion
          • After GI surgery or malabsorbtion syndromes
      • Blood loss
          • Chronic GI bleed scan cause loss of 2-4mls
          • Black stools or melena requires 50 to 75ml of blood from
            UGI tract
      • At risk population:
          •   Pregnancy because of increased iron needs
          •   Pre-menopausal women
          •   Low socioeconomic background
          •   Older adults
          •   Blood loss


                                                                       9
Anemia's Related to Decreased Erythrocyte Production
                       Clinical Manifestations

  • Asymptomatic early in the disease
  • Chronic Symptoms:
      • Pallor – most common
      • Glossitis – inflammation of the tongue
      • Cheilitis – lesions of the corners of the lips
      • Headache, dizziness, parasthesias, DOE, burning
        sensation of the tongue…..all due to ↓ iron.
  • Diagnostics
      • Lab testing
      • Stool for occult blood
      • Colonoscopy
      • Take iron in an acidic environment, with OJ, empty
        stomach, one hour prior to breakfast. Don’t take with milk,
        reduces absorption. > fluids to prevent constipation.
  • Treatment
      • Goal: treat underlying cause Foods > in iron = liver, meat,
        eggs, dark green veggies, raisins, prunes, apricots, fortified
        cereals, breads.



                                                                         10
Anemia's Related to Decreased Erythrocyte Production

• Drug therapy
   • Oral Iron Replacement – Ferrous Sulfate
   • Iron is best absorbed from the duodenum
       • Enteric coated or SR and not wise choice
   • Dosage should be 150mg to 200mg TID
   • 300mg of ferrous sulfate has 60mg of iron available
   • Best absorbed in an acidic environment
           • Take with OJ, empty stomach, one hour prior to
             breakfast.
           • Don’t take with milk, reduces absorption.
           • ↑ fluids to prevent constipation.
   • GI side effects : heartburn, constipation and diarrhea
   • Diet teaching: Foods ↑ in iron: liver, meat, eggs, dark green
     veggies, raisins, prunes, apricots, fortified cereals, breads


                                                                     11
                  Nursing Interventions
•   Obtain a history of symptoms, dietary intake and past hx of anemia
•   Possible sources of blood loss
•   Examination for: Tachycardia, pallor DOE, s/s of GI or other bleeding
•   Assess diet for inclusion of Iron rich foods
•   Assess level of fatigue and sleep
•   Assist in scheduling activities and rest patterns
•   Maximize tissue perfusion
     •   A/E for palpitations, chest pain, dizziness and SOB….minimize activities which
         cause these symptoms
     •   Elevate HOB and supplemental Oxygen
•   Education
     •   Proper nutrition
          • Well balanced diet
     •   Teach about Iron supplements
          • Take on empty stomach
          • Epigastric discomfort
          • Stool changes
     •   Follow up lab studies


                                                                                          12
      Vitamin B12 (Pernicious) Anemia
• Gastric secretion of Intrinisic Factor(IF) is defective
• IF is required for Cobalamin absorption
• Impaired B12 absorption in the small intestine due to lack of IF or
  destruction of the parietal cells.
   • Clinical manifestations: as Anemia- normal levels 200-900ng/L
        • Sore tongue, anorexia, vomiting and abdominal pain
        • Neuromuscular manifestations-parasthesias, weakness
        • Low Hgb
   • Schilling test abnormal test = pernicious anemia
        • Indirect test of IF deficiency
        • Evaluates the ability to absorb vitamin B12
   • Nursing management
        • includes IM B12 1000mg weekly IM or intra-nasally.
        • B12 for the rest of their life due to lack of IF
   • Without vit B12 leads to macrocytic anemia, GI disorders,
      paresthesia, gait problems & death
                                                                        13
               Folic Acid Deficiency
• Folic acid is necessary for DNA synthesis leading to
  RBC formation and maturation.
   • Common Causes:
       • Poor nutrition (lack of green vegetables, liver, fruits)
       • Malabsorption syndromes-small bowel disorder
       • Drugs, alcohol and hemodialysis (folic acid is lost).
   • Clinical manifestations are similar to vitamin B 12 deficiency

   • Treatment:
       • Folic Acid replacement: PO 1-5 mg/OD, standard dose is 1mg.
   • Vitamin C helps with development
   • Encourage liver, green veggies, legumes




                                                                       14
                       Blood Loss
• Acute Blood Loss
   • Trauma or Blood vessel rupture due to trauma
   • Complications of surgery
   • Diseases that disrupt vascular integrity i.e Shock, the body
     reacts by vasoconstriction.
• 30% blood loss
   • symptoms with exertion only
• 40% blood loss
   • rapid, thready pulse, CO low, clammy skin. Blood is being
     shunted centrally
• 50% Blood loss
   • shock & potential death
• First identify the cause and stop bleeding
• Expand blood volume, pain from organ displacement,
  check blood work, administer albumin, & colloids


                                                                    15
            Polycythemia Vera
• Overproduction of RBC’s ↑ blood viscosity, volume
• Myeloproliferative disorder – Chromosome mutation
   •   Hgb to 18g/dl, RBC 6 million/mm, HCT > 55%.
   •   Common in patients over 50
   •   Splenomegaly and hepatomegaly – organ engorgement
   •   Headache, ↑BP, vertigo, dizziness, angina
   •   Increased uric acid production – gout
   •   Plethora or ruddy complexion, pruritis
   •   Hemorrhagic phenomenon
         • Nosebleeds, petichiae, thrombus-↑stroke risk
• Treatment: aimed at ↓blood volume and viscosity
   • Phlebotomies to keep Hct < 45%
   • Allopurinol for uric acid
   • Teach S/S of bleeding & clotting, discourage smoking, low sodium
     diet, frequent rest periods
   • Myelosuppressive agents-Hydrea, Alkeran
   • Antiplatelet therapy – ASA
   • Chemotherapy-bone marrow suppression
                                                                        16
               Thrombocytopenia
• Number of platelets is abnormally low
   • Below the normal of 150,000 to 400,000
   • Counts below 50,000 cause prolonged bleeding, below
     20,000 life threatening
   • Platelets help the blood clot
   • Manifests as prolonged bleeding or spontaneous bleeding.
   • Petechiae = micro hemorrhages.
   • Purpura when petechaie are numerous, the resulting reddish
     skin bruise.
   • Ecchymosis larger purplish lesions that are caused by
     hemorrhage
• Causes: Leukemia, Drugs-ASA, Infection, Lupus
   • Immune thrombocytopenia, patient makes antibiodies
     against their own platelets( survival is 1-3 days).




                                                                  17
               Thrombocytopenia
• Treatment Options:
  • Platelet transfusions
  • Steriod therapy
  • Splenectomy to reduce macrophages which destroy
    platelets.
  • Avoid sharp objects, razors, no contact sports, no IM’s, no
    rectal temps, oral care, no spicy foods.
  • If blood work, hold for 5 minutes or greater
  • Watch for hidden ASA in OTC
  • Periodic check for bleeding times and platelet counts…
  • NO ASA




                                                                  18
DIC-Disseminated Intravascular Coagulation

 •   Abnormal response of the clotting cascade
 •   Small blood clots develop throughout the blood stream blocking small
     vessels depleting platelets and clotting factors needed to control
     bleeding
 •   The clotting factors run out & there is excessive bleeding.
 •   Clinical manifestations:
      •   Bleeding -Pallor, petechiae, hematomas, GI bleeding, hematuria, dizziness,
          headache, musculoskeletal changes
      •   Thrombosis- cyanosis, ischemia, pulmonary emboli, resp. distress
 •   Life threatening, mortality is > 80%
 •   Occurs with septic shock.
 •   Bleeding out of every orifice, platelets are destroyed.
 •   PT & PTT is increased, Platelets are decreased.
 •   Medical Management:
      •   Tx underlying cause
      •   Heparin, Xigris
 •   Nursing Management:
      •   Early detection of bleeding


                                                                                       19
                        Neutropenia
• Reduction in the neutrophils
• Neutrophils play a role in phagocytosis of pathogenic microbes
• Definition: neutrophil count of less than 1,000- 1,500/uL
   • Normal level: 4000-11,000/uL
   • It is not a disease, it is a syndrome that occurs with a variety
     of diseases
   • As a result of chemotherapy
• Patient is predisposed to an infection:
   • Observe for chills, ↑temp, sore throat and cough
   • Abnormal s/s of inflammation
   • Minor infections can lead to sepsis
   • Good mouth care to prevent pneumonia.
   • Protective isolation, private room, limit visitors, handwashing.
   • Normal flora, transmission by hand, food
   • Neupogen – stimulates production of neutrophils



                                                                        20
                      Leukemias
• Acute Lymphocytic (ALL)
  • Most common in children
  • Malignant growth of Lymphoblasts
     • Large numbers of immature white blood cells
     • Proliferate the bone marrow and lose ability to mature


• Chronic Lymphocytic (CLL)
  • Slow growth of lymphoid cells in lymph nodes, failure
    of bone marrow, invasion of malignant cells into the
    organs
  • Most age 50 > and men
  • Prognosis poor


                                                                21
                    Leukemias
• Acute Myelogenous Leukemia (AML).
  • Make to many immature myeloblasts infiltrate organs
  • Normal cells turn in to granulocytes (WBC)… leukemia
    blast cells don’t
  • Most common adult (15-39) leukemia, exact cause is
    unknown
  • Prognosis generally poor
• Chronic Myelocytic Leukemia (CML)
  • Slow abnormal growth of granulocytes
     • Chromosomal abnormality called Philadelphia
       chromosome.
  • Affect age 50 >, more males than females
  • Prognosis generally poor, worse if Ph chromosome
    present
                                                           22

     marrow and blood.
   • Symptoms are the same
• Treatment
   • Outpatient chemo & radiation
   • High risk for infection, as survival rate increases
   • Risk of secondary malignancy increases
                                                                      26

  bank!
• Check ABO compatibility
• Inspect blood for abnormalities
• Check pt ID
• Stay with pt during first 15min of transfusion
• Monitor vs per protocol
• Monitor for s/s adverse reactions
• PRBCs – give over 2h-4h (but not more than 4h)
• FFP, Platelets- run in as quickly as possible



                                                        27
          Transfusions

      carries A&B antigens, O has no antigens
  • O- universal donor
  • AB+ universal recipient
  • Rh factor
    - absent
    + present
  • Blood testing is done to determine
    compatibility
