RBC Disorders
Presentation by: Joyce Smith RN, BSN

* Decreased Production of RBC
* Iron Deficiency Anemia
* Vitamin B12 Deficiency Anemia
* Folic Acid Deficiency Anemia
* Aplastic Anemia

Fe Deficiency Anemia
* Common world wide
* Affects 10-30% of population in US
* Common in premenapausal woman, infants, children, adolescents, & elderly
* Develops slowly

A&P

* Occurs when supply of Fe is too low for optimal RBC formation
* Iron RDA
* 10mg/d M,
* F 12-49 15 mg
* Typical American diet provides 10 to 20 mg/d
* Many woman consume only 12.4mg/d

Cause of Development

* Inadequate absorption or excess Fe loss
* Inadequate dietary intake of foods high in Fe
* Principal cause in adults acute or chronic bleeding
* Secondary to trauma
* Excessive menses
* GI bleeding
* Blood donation

Diagnostics

* Hgb Panic value < 5g/dl
* Hgb level can drop to 3.6g/dl
* Total RBC count rarely below 3 million/dl
* MCH < 27 pg
* MCHC 20 to 30 g/dl
* Serum Fe as low as 10mcg./dl
* HCT < 47 ml/dl M
* HCT < 42 ml/dl F
* Fe binding capacity 
* Serum ferritin level 
* Bone marrow may also be indicated

Symptoms

* Pallor, glossitis
* Dizziness, irritability, numbness & tingling in limbs, fatigue, decreased concentrated & HA
* Tachycardia & dyspnea on exertion
* Sensitivity to cold, brittle hair & nails
* Atrophic glossitis, stomatitis, dysphagia
