of erythrocytes in blood

20
Q

mean corpuscle volume (MCV)

A

size of erythrocytes, rare, seen with some anemia

21
Q

mean corpuscle hemoglobin (MCH)

A

amt of Hgb in erythrocyte by wt; rare, seen with some anemia

22

leukocytosis

A

inc WBCs

24

leukopenia

A

dec leukocytes; under 5000

25
Q

neutropenia

A

low neutrophils

26
Q

total counts

A

degree of immune response to a pathological process (mild vs more)

27
Q

CBC includes…

A

WBCs, platelets, RBCs, Hct, Hgb

28
Q

WBC w/ Diff (CBC with Diff)

A

tells which WBC is elevated/changed; means an inc in one type NOT a dec in another type

29
Q

Parts of CBC with Diff

A

total # WBCs in mm3 (absolute #) AND proportion of each of the WBCs in a sample of 100 WBCs

30
Q

How does inc temp affect infection?

A

body’s protective response; stops or dec growth of microorgs, inc immune response, dec virulence of some bac

31
Q

Neutropenia char

A

determined by absolute neutrophil count (ANC); under 1000; most often in cancer pt from disease or tx; sus to bac infx (can be life-threatening)

32
Q

neutropenic precautions

A

good hygiene, avoid contact with ppl who are sick, avoid raw fruits, veg, grains, keep door closed

33
Q

Filgrastim (Neupogen)

A

Granulocyte colony stimulating factor (GCSF) class; hematopoietic agent; leukopoietic growth factor produced by recombinant DNA tech

34
Q

FIlgrastim MOA

A

promotes proliferation, differentiation, activation of cells that make granuloyctes

35
Q

Filgrastim indx

A

malignancies, chemo-induced leukoepnia, bone marrow transplant, harvesting of hematopoietic stem cells, chronic neutropenia

36
Q

Filgrastim SE and NC

A

IV and SQ; bone pain, leukocytosis

37
Q

Pegfilgrastim (Neulasta)

A

long acting derivative of fligrastim that inc production of neutrophils

38
Q

Pegfilgrastim (Neulasta) SE and NC

A

SQ; causes bone pain; long half life so don’t give often
