lead poisoning
sickle cell
B-thalassemia


Define iron deficiency anemia - ANS reduction in the iron stores of the body causing an
inadequate production of hemoglobin


What is iron needed for? - ANS to make hgb


signs and symptoms of iron deficiency anemia - ANS pallor
tachycardia
tachypnea
lethargy
fatigue
irritability


Why are neonates at risk for iron deficiency anemia? - ANS -lack the maternal iron stores
-Full term infants have maternal iron stores until approximately 6 months of age
-Havent had the time in utero to store up the needed iron supply (preterm)


How can you treat a neonate with iron deficiency anemia? - ANS Iron fortified formula
2

3.Chronic blood loss


Food with good sources of iron - ANS red meat, egg yolk, leafy greens, dried fruits, fortified
cereals/formulas, beef, chicken, fish, beans, nuts, seeds, peanut butter, eggs, prunes, whole
grain bread


How is iron deficiency anemia diagnosed? - ANS Serum lab evaluation:
-Red blood cell count = microcytic (small) and hypo chronic (pale in color)
-low hemoglobin
-low hematocrit
-low reticulocyte count
-low serum iron concentration
-high total iron binding capacity


What is the goal of treatment for iron deficiency anemia - ANS treat medical problem
causing malabsorption or blood loss/ identify cause


What is the treatment method for iron deficiency anemia? - ANS Increase iron take
~ Dietary sources
~Medication supplement (ferrosol or ferrous sulfate)

-Plumbing from lead pipes
-soil


Dietary factors of lead poisoning - ANS -iron deficiency
-calcium deficiency


Patient-child interactions - ANS -Job or hobby exposure
-home remedies or cultural practices


How does lead poisoning cause anemia - ANS lead can replace iron on Hgb causing O2 to not
be delivered causing anemia


Clinical manifestation of lead poisoning - ANS -Asymptomatic
-Signs of anemia
-Growth and developmental lags
-Behavioral changes
-Neurologic changes
-Gastrointestinal changes


can someone be asymptomatic if they have lead poisoning - ANS yes


signs of anemia (lead poisoning) - ANS pallor, fatigue, weakness, shortness of breath,
headache, tachycardia - because lead replaces iron in Hgb causing anemia
