FNP 3: hematology

where are blood cells produces and what regulates the production

bone marrow

erythopoetin

Neutrophils

must abundant wbc

first line defense

lymphocytes

fights chronic and viral infections

used in the immune response system

monocytes

largest cell and is the 2nd to respond

removes injured or dead cells

what can a high monocyte count indicate

recovery phase from acute infection

eosinophils

allergic or parisite infection

basophils

releases heparin and histamines

prevents clotting and dilates vessels w

what affect does steroids have on basosinophils and eosinophils

decreases the number of them

normal rbc

4.6-6

what are immature rbc called

reticulocytes

erythrocytopenia

low rbc

erythocytosis

high rbc

polycythemia vera

increased blood viscosity causing cyanosis and hemorrhage

promote hydrating and walking

normal platelet count

150-400

hormal hgb male

14-18

normal hgb female

12-16

normal hematocrit male

40-52

normal hematocrit female

38-47

reasons for increased hgb

dehydration

polycythemia vera

increased altitude

in order to have accurate levels of hct what must the patient ensure

hydration

mcv

avergage volume or size of rbc

male mcv

80-98

female mcv

82-89

mchc

average concentration of hub in 1 rbc

mchc normal value

32-36%

mch

weight of hemoglobin

normal mch

27-31

rbc distribution width (RDW)

predicts microcytic vs macro cystic anemisas earlier than mcv

reticulocyte count

measures bone marrow activity and dx anemias

normal retic male

0.5-1.5%n

normal retic female

0.5-2.5%

what suppresses retic counts
