Focus on Anemia:

Focus on Anemia Nursing Management: Hematologic Problems Elinda Steury, MSN, RN, CCRN

Objectives:

2 Objectives 1.  Assessment of a client with a Hematologic Disorder 2.  Identify differences of Hematologic Disorders including pathophysiology for clients across the life span ( anemias , coagulation disorders). 3. Nursing interventions for diverse clients (cultural, developmental, and socioeconomic) with a complex Hematologic Disorder 4. Assimilate pharmacological and non-pharmacological interventions related to complex Hematologic disorders. 5. Discuss diagnostic tests and interventions associated with complex Hematologic disorders 6. Apply the nursing process to the care of clients experiencing a complex Hematologic disorder.

Anemia:

Anemia A deficiency 1. 2. 3. Diverse causes 1. 2. 3.

Causes of Anemia:

Causes of Anemia

Anemia:

Anemia RBC function 1. 2.

Erythrocyte Production:

Erythrocyte Production Erythropoietin (EPO) is a glycoprotein primarily produced in the kidneys (10% in the liver)

Anemia (Cont’d):

Anemia (Cont’d) Classified as Morphologic Cellular characteristics Descriptive, objective laboratory information Etiologic Underlying cause

Anemia Clinical Manifestations:

Anemia Clinical Manifestations Caused by the body’s response to tissue hypoxia Hemoglobin (Hb) levels are used to determine the severity of anemia

Anemia :

Anemia Integumentary Manifestations Pallor Jaundice Pruritus Cardiopulmonary Manifestations Inc. H/R, Resp Rate, inc. stroke

Anemia Clinical Manifestations:

Anemia Clinical Manifestations Mild = Hb 10 to 14 g/dl Moderate = Hb 6 to 10 g/dl Severe = Hb <6 g/dl

Anemia Nursing Assessment:

Anemia Nursing Assessment Subjective Data Important health information Past health history Medications Surgery or other treatments Functional health patterns

Anemia Nursing Assessment (Cont’d):

Anemia Nursing Assessment (Cont’d) Objective Data General Integumentary Respiratory Cardiovascular Gastrointestinal Neurologic

Anemia Nursing Management :

Anemia Nursing Management Goals Correct cause of anemia Assume normal activities of daily living Maintain adequate nutrition Develop no complications related to anemia

Anemia Nursing Implementation:

Anemia Nursing Implementation Dietary and lifestyle changes Blood or blood product transfusions Drug therapy Oxygen therapy Patient teaching Nutrition intake Compliance with drug therapy

Anemia Gerontologic Considerations:

Anemia Gerontologic Considerations Common in older adults 1. 2. Signs and symptoms may go unrecognized or mistaken for normal aging changes

Anemia Nursing Diagnoses:

Anemia Nursing Diagnoses Activity intolerance Imbalanced nutrition: Less than body requirements Ineffective therapeutic regimen management Potential complication: Hypoxemia

Iron-Deficiency Anemia:

Iron-Deficiency Anemia One of the most common chronic hematologic disorders Iron is present in all RBCs as heme in hemoglobin and in a stored form Heme accounts for two thirds of the body’s iron

Iron-Deficiency Anemia Etiology :

Iron-Deficiency Anemia Etiology Inadequate dietary intake Malabsorption Blood loss Hemolysis

Iron-Deficiency Anemia Clinical Manifestations:

Iron-Deficiency Anemia Clinical Manifestations General manifestations of anemia common finding: second most common:

Iron-Deficiency Anemia Diagnostic Studies:

Iron-Deficiency Anemia Diagnostic Studies Laboratory findings Decrease in: Hb, Hct MCV serum iron, TIBC, bilirubin Stool guaiac test Endoscopy Colonoscopy

Iron-Deficiency Anemia Collaborative Care:

Iron-Deficiency Anemia Collaborative Care Goal is to treat the underlying disease

Iron-Deficiency Anemia Drug Therapy:

Iron-Deficiency Anemia Drug Therapy Oral iron Inexpensive Convenient Factors to consider IV IM

Iron-Deficiency Anemia Nursing Management:

Iron-Deficiency Anemia Nursing Management At-risk groups Premenopausal women Pregnant women Persons from low socioeconomic backgrounds Older adults Individuals experiencing blood loss

Iron-Deficiency Anemia Nursing Management (Cont’d):

Iron-Deficiency Anemia Nursing Management (Cont’d) Diet teaching Supplemental iron Discuss diagnostic studies Emphasize compliance Iron therapy

Thalassemia Etiology and Clinical Manifestations:

Thalassemia Etiology and Clinical Manifestations Population: An autosomal recessive: Thalassemia Minor: Heterozygous Thalassemia Major: Homozygous

Thalassemia Collaborative Care:

Thalassemia Collaborative Care Diagnostic tests: Interventions: Treatments: Complications:

Megaloblastic Anemias:

Megaloblastic Anemias Megaloblastic Anemias (macrocytic): Nutritional anemia resulting in defective DNA synthesis in RBCs Primary Causes: 1. 2.

Cobalamin Deficiency Etiology :

Cobalamin Deficiency Etiology Intrinsic factor (IF) IF is required for cobalamin absorption in the small intestine Causes:

Cobalamin Deficiency Clinical Manifestations :

Cobalamin Deficiency Clinical Manifestations General symptoms of anemia Neuromuscular manifestations

Cobalamin Deficiency Diagnostic Studies :

Cobalamin Deficiency Diagnostic Studies RBCs are macrocytic &Abnormal shapes contributing to to erythrocyte destruction Decreased s erum cobalamin levels Normal Folate levels Schilling test

Cobalamin Deficiency Collaborative Care :

Cobalamin Deficiency Collaborative Care Parenteral or Intranasal Depending on Cause: Increase in dietary cobalamin does not correct the anemia Still important to emphasize adequate dietary intake

Cobalamin Deficiency Nursing Management :

Cobalamin Deficiency Nursing Management Familial disposition Prevent injuries related to the patient’s diminished sensations

Folic Acid (Folate) Deficiency :

Folic Acid ( Folate ) Deficiency Megaloblastic anemia Characterized by macrocytic RBCs Folic acid is required for DNA synthesis

Folic Acid Deficiency (Cont’d) :

Folic Acid Deficiency (Cont’d) Causes: Clinical Manifestations: Diagnostic Findings: Treatment:

Anemia of Chronic Disease:

Anemia of Chronic Disease Underproduction of RBCs Mild shortening of RBC survival

Anemia of Chronic Disease:

Anemia of Chronic Disease Underproduction of RBCs Mild shortening of RBC survival

Anemia of Chronic Disease (Cont’d):

Anemia of Chronic Disease (Cont’d) Causes End-stage renal disease Primary factor: ↓ Erythropoietin Chronic liver disease Chronic inflammation Malignant tumors Chronic endocrine diseases

Anemia of Chronic Disease (Cont’d):

Anemia of Chronic Disease (Cont’d) Anemia of chronic disease findings ↑ Serum ferritin ↑ Iron stores Normal folate and cobalamin levels

Anemia of Chronic Disease (Cont’d):

Anemia of Chronic Disease (Cont’d) Treating underlying cause is best Rarely blood transfusions Erythropoietin therapy

Aplastic Anemia:

Aplastic Anemia Pancytopenia Decrease of all blood cell types RBCs White blood cells (WBCs) Platelets Hypocellular bone marrow

Aplastic Anemia Etiology:

Aplastic Anemia Etiology Low incidence Manageable with erythropoietin or blood transfusion Can be a critical condition Hemorrhage Sepsis

Aplastic Anemia Clinical Manifestations:

Aplastic Anemia Clinical Manifestations Gradual or sudden Onset Symptoms caused by suppression of any or all bone marrow elements General manifestations of: anemia Neutropenia Thrombocytopenia

Aplastic Anemia Diagnostic Studies:

Aplastic Anemia Diagnostic Studies Confirmed by laboratory studies Normocytic, normochromic anemia

Aplastic Anemia Nursing Management:

Aplastic Anemia Nursing Management Preventing complications from infection and hemorrhage Untreated prognosis is poor 75% fatal Treatment options Bone marrow transplantation Immunosuppressive therapy
