Nursing Management of Children with Hematologic, Immunologic, and Metabolic diseases Flashcards
RBC’s are unusual BECAUSE:
- Strange Shape
- No Nucleus
- changes shape to squeeze through capillaries
- contains HGB to transport O2
- 120 day lifespan & liver and spleen remove with the help of macrophages
- Men have more RBC’s then women
Red Blood Cells
- NO nucleus
- Bioconcave
- most abundant cells in the body
- account for approximately 40-45% of blood
- HEMATOCRIT measures the % of blood made up of RBC
Three Sizes of RBC:
- Normocytes
- Microcytes
- Macrocytes
Three RBC Shapes:
- Globular Cells
- Sickle Shaped Cells
- Other Irregularly shaped cells
Neutrophils:
- Most Prevalent
- 54-62% of WBC
- PRIMARY DEFENSE IN BACTERIAL INFECTIONS
LYMPHOCYTES:
- *25-33% of WBC
- Contain Histamin, Heparin, Seratonin
- INCREASE BLOOD FLOW TO AREAS OF INJURY
- PREVENT EXCESSIVE CLOTTING
MONOCYTES:
- 3-7% of WBC
- Large Phagocytic cells (EATING Cells)
- INVOLVED IN EARLY STAGES OF INFLAMMATORY REACTIONS
EOSINOPHILS:
- 1-3% of WBC
* INCREASED IN ALLERGIC DISORDERS, PARASITIC DISEASE, AND NEOPLASMS
BASOPHILS:
- 0.75% of WBC
- Contain Histamine, Heparin Seratonin
- INCREASE BLOOD FLOW TO AREAS OF INJURY
- PREVENT EXCESSIVE CLOTTING
ANC:
- % Neutrophils / Bands
- Indicates body’s capability to handle bacterial infection
- *Increased bands = body working really hard to fight infection
Platelets
- Cellular fragments needed for blood clotting
* Normal count 150-400,000 platelets/mm3 of blood
Plasma
Liquid portion of blood that contains clotting factors that helps make bleeding stop
Complete Blood Count (CBC): MCV
- 77-95 Cubic Microns
- -Mean Volume (size) of red blood cell
CBC: MCH
- 25-33% mcg/cell
- -Average weight of hemoglobin in single red blood cell
CBC: MCHV
- 31-37% grams per cell
- -Average Concentration of Hemoglobin in red blood cell
Anemias
*Basic pathologic process: Decrease the oxygen carrying capacity of the blood
NURSING FOCUS:
*Assess Child’s energy needs
*Decrease tissue oxygen needs
*Adjust child’s exertion level to allow child to do as much as possible
*Balance how much 02 comes in with how much they use.
Iron Deficiency Anemia
- ANEMIA CAUSED BY INADEQUATE SUPPLY OF DIETARY IRON
- Most prevalent nutritional disorder in the US
- Children as particularly susceptible
- preterm infants
- Children 12-36 mo
- Adolescents
Iron Deficiency Anemia Pathophysiology:
- Decreased Supply
- impaired absorption
- increased need for iron
- affects synthesis of Hgb
Causes of Iron Deficiency:
- Blood Loss
- Excessive milk ingestion
- Depletion of fetal iron stores after birth
Iron Deficiency: Therapeutic Management
Focus: INCREASE AMOUNT OF SUPPLEMENTAL IRON --Dietary counseling --Administration of supplemental iron **Oral (preferred) **Parenteral PROGNOSIS: --Very Good --Severe and longstanding > cognitive, behavioral, and motor impairment
Misc Iron Deficiency therapeutic Management:
- Dietary increase is not sufficient
- Oral supplements administered for 3 mo
- Adequate dosage indicated by tarry green stools
- Iron Therapy can cause nausea and diarrhea but given with meals is good.
- Absorption enhanced with Vit C or Citric Acid
