What is the therapeutic level for INR for person on coumadin?
PT/INR
the therapeutic dose of coumadin is monitored by the ____ and
reported by the ____?
INR
International Normalized Ratio - a calculation based on the PT
used to monitor patients using blood thinners
INR equation
(PTtest/PTnormal) ^ISI
blood clots more slowly
what does a high INR mean?
blood clots more quickly
what does a lower INR mean?
MCV
mean cell volume
normocytic is 80-100fL
,2|Page
MCV equation
(Hct x 10)/RBC
MCH
mean cell hemoglobin
-avg weight of hemoglobin per RBC
normal is 26-32 pg
MCH equation
(Hgb x 10) / RBC count
MCHC
mean cell hemoglobin concentration
-avg amount of RBC volume that is made up of hemoglobin
-normochromic =32-36%
MCHC equation
(Hgb x 100)/Hct
Factor I
fibrinogen
Factor I
-thrombin substrate
-polymerizes to form fibrin
-when hydrolyzed by thrombin, fibrinogen forms
-gpIIb/IIIa binding
- 3 diff polypeptide disulfide bridges
,3|Page
Factor II
prothrombin
Factor II
-serine protease
-most abundant vitamin K factor
- Factor X, V, PF3, Ca convert it to thrombin
-G20210A
Factor III
Tissue factor
Factor III
cofactor
extrinsic
activates FVII w/ Ca
Factor IV
ionic calcium
Factor IV
mineral
rarely called by RN
in all pathways
aggregation involving fibrinogen
Factor V
Labile Factor
, 4|Page
Factor V
cofactor
prothrombin complex
serine
known as proaccelerin
R506Q
Factor VII
Stabile factor
Factor VII
Serine protease
Proconvertin
Extrinsic
Vitamin K dependent serine
Inactive zymogen
Congenital AR (deficiency)
TF + Ca activates it
Factor VIII
antihemophilic factor
Factor VIII
Cofactor
Intrinsic
Serine
Circulates w/ vWF
