Patho

  • Microcytic (note that the cells are not just less in number, but smaller)
  • Red Blood Cells are small in size
  • small cells have a lower capacity to carry oxygen. 
  • Decreased oxygen explains most of the symptoms of anemia (e.g., fatigue and shortness of breath
  • Serum Ferritin < 10 (normal 12-300) (Ferritin is the protein that contains the iron in the RBC).
  •  

Causes

  • ⇓ RBC production
    • 2/3 of iron in Hgbs ⇒ less RBCs⇒Less Hgb⇒less iron
  • Poor intake of iron and poor diet
  • Vegetarian diet
  • Inability to absorb iron (e.g. bariatric surgery or Celiac disease
  • Blood loss
  • Women and elderly are at risk
  • Pregnancy

Symptoms

 

  • Severe symptoms: smooth, red tongue and brittle and ridged nails

Nursing Interventions

  • Increase intake of iron
    • red meat
    • Organ meat
    • egg yolks
    • kidney beans
    • leafy green veggies
    • Iron-fortified cereals
    • Oysters and tuna
    • Seeds
    • Fish
  • Adequate rest
  • Avoid coffee or tea since inhibit absorption of iron.
  • Iron Supplement
  • Liquid iron: drink with a straw and brush teeth afterwards.
  • DO NOT take iron with calcium (milk or antacids) because it ⇓ absorption.
  • Iron names (ferrous sulfate, ferros gluconate, ferrous fumarte)
  • May be given IV as well!
