,WBC
Neutrophil
Normal RBC
Female: 3.8-5.1
Male: 4.3-5.7
Normal hemoglobin
Female: 11.7 - 16.0 g/dL
Male 13.2 - 17.3 g/dL
Normal Hematocrit
Female: 35-47%
Male: 30-50%
Normal platelet count
150,000 - 450,000
<150,000 = thrombocytopenia
Normal WBC count
4,000 - 11,000
Normal neutrophil count
50 - 70 %
or
2200 - 7700 cells
define Anemia
a deficiency in the number of erythrocytes, the quantity of hemaglobin, and/or
the volume of packed RBCs (hematocrit)
-not a disease, a clinical finding that arises from many causes
, manifestations of Anemia
reflect hypoxia
-Fatigue
-Tachycardia
-Tachypnea
-Restlessness
-Irritability
-Dyspnea
3 Main classifications/causes of Anemia
-Decreased RBC Production
-Blood Loss
-Increased RBC Destruction (Hemolytic anemias)
Manifestations of severe anemia
symptoms are constant (at rest & during activity)
-Daily tasks are difficult to complete. Mental abilities are impaired. Emotional
changes. Headache, Noticeable pallor, tachycardia, angina. Tachypnea, orthopnea,
Sensitivity to cold. Dyspnea at rest.
-Int: Pallor, jaundice, pruritis
-Eyes: icteric conjunctiva & sclera, retinal hemorrhage, blurred vision
-Mouth: glossitis, smooth tongue
-CV: Tachy, ↑Pulse pressure, systolic murmurs, int. claudication, angina, HF, MI
-Pulm: Tachypnea, Orthopnea, dyspnea @ rest
