Chapter 32: Iron-Deficiency Anemia (Children) Flashcards
Iron-Deficiency Anemia
microcytic (small), hypochromic (paler in color) anemia caused by an inadequate supply of iron
- common in infants
- premature infants at high risk b/c of their decreased fetal iron supply
Iron
essential for the production of hemoglobin
-when inadequate, the production of hemoglobin is diminished; as a result there is a decreased oxygen0-carrying capacity of the blood
Factors Associated with the Development of Iron-deficiency Anemia in Infants and Children
- stop breastfeeding too early
- giving formula that is non-iron-fortified
- prolonging bottle-feeding
- drinking more than 2 cup of cow’s milk a day (children 12 months and older)
Common Causes of Iron-Deficiency Anemia
> Decreased Iron Supply
- inadequate iron supply at birth
- nutrition: deficient iron intake, excessive milk, limited solid foods, poor eating habits, vegetarian diet, increased fast foods
> Increased Iron Demands:
-Growth: low birth weight; twins or multiple births, prematurity/infants; adolescence; pregnancy; cyanotic congenital heart diseases (e.g. tetralogy of Fallot)
> Blood Loss:
-acute, chronic, parasite infection, GI tract (the most common site)
> Inability to Form Hemoglobin
-lack of vitamin b12 (e.g. pernicious anemia); folic acid deficiency
> Impaired Absorption
- presence of iron inhibitors: phytates, phosphates, or oxalates; gastric alkalinity
- malabsorption syndrome (e.g. celiac disease, severe prolonged diarrhea, post-gastrectomy, inflammatory bowel disease)
Signs and Symptoms
vary with severity of disorder -if has mild, may be asymptomatic -the deficiency may not be apparent until lab tests are performed (decreased hemoglobin/hematocrit) >with moderate to severe iron-deficiency anemia: -irritability -fatigue -delayed motor development -tachycardia -SOB -decreased activity level -pale skin -conjunctival pallor -listlessness -systolic heart murmur -hepatomegaly (enlarged liver)
Pica
the eating of non-nutritive value such as starch, clay, ice, or paper
- may be associated with iron-deficiency anemia
- iron deficiency, alone or with anemia, may result in impairment of cognitive skills that may not be reversible
Diagnosis
based on patient history and physical examination findings
-laboratory tests= those that quantify or describe hemoglobin, iron concentration, and morphological changes in RBC
Nursing Care
- prevention is key to avoiding iron-deficiency anemia
- ensure children eat iron-rich foods such as beans, meat, fortified cereals, eggs, and green leafy vegetables
- if oral iron supplements prescribed, parents are taught how to properly administer them to child
Iron Rich Foods to Give to Children
- beans
- meat (red)
- whole grains
- nuts
- fortified cereals
- eggs
- green leafy vegetables
Medical Care
early identification and recognition is essential
-this anemia can be avoided with appropriate food selections
-dietician provides nutritional counseling and assists with obtaining recommended iron-fortified formula and cereal
-oral iron supplements may be prescribed if dietary treatments are not successful (3 mg/kg per day based on body weight in 1 to 2 divided doses)
-severity of anemia dictates the monitoring and frequency of laboratory testing and follow-up
-several days after initiating iron replacement therapy, the reticulocyte count will rise, which is an indicator of RBC production
>children who are compliant with oral iron replacement therapy usually have a clinical response within 1 to 2 weeks; importance of compliance with iron administration and of follow-up visits to monitor hemoglobin, hematocrit, and reticulocyte count
Preventing Iron-Deficiency Anemia: What to tell Parents
- feed your infant breast milk or commercial infant formula recommended for the first 12 months of life
- “are you aware of community resources such as WIC to provide assistance with formula and iron-fortified foods?”
- be sure to use iron-fortified cereal from 6 to 12 months of age
- do not feed your infant cow’s milk before 12 months of age b/c it does not contain iron and essential nutrients. After 12 months, limit the amount of cow’s milk to 18 to 24 ounces per day
- offering solids before giving the bottle helps prevent iron deficiency
- tell adolescents on a vegetarian diet or weight reduction diet to understand proper dietary alternatives. Red meats, beans, whole grains, nuts, and iron-fortified cereals are good sources of iron
Education about Oral Iron Intake/Administration
- take between meals b/c absorption is improved in an acidic environment
- administer with a glass of orange juice may enhance absorption
- NOT taken with tea or dairy products b/c they may adversely affect the absorption process
- liquid iron preparations may stain teeth; administer with a dropper or drink through a straw; rinse mouth out after taking liquid medication
- iron can be constipating; increase fiber and water intake
- possible side effects: gastric upset, nausea, vomiting, and constipation; black, tarry stools are common and normal for children taking iron supplements
- keep out of reach of small children, ingestion of excessive quantities can be toxic and fatal
An overweight Child diagnosed with iron-deficiency anemia
-while most infants are underweight with this disease, overweight may also have this disorder
-are overweight b/c of excessive milk ingestion, known as “milk baby”
-infants are chunky, pale, and have a “porcelain-like” appearance
-have poor muscle development and are susceptible to infections
