How many RBC's per microliter of blood 4.2-6.2 million
What is the second most numerous WBC? Lymphocyte with 20-40%
Their numbers increase in intracellular infections and TB Monocytes
Their numbers increase in bacterial infections and often Neutrophils
are first on scene
These WBC's play an important role in viral infection as Lymphocytes
well as in immunity.

Test used to evaluate the intrinsic pathway and monitor APTT also know as PTT
heparin therapy
Test used to evaluate the extrinsic pathway and also used PT
to monitor warfarin therapy
Fibrinolysis Breakdown and removal of a clot
Converts the temorary platelet plug into a stable fibrin clot Coagulation phase
2nd choice vein for venipuncture most often the only one Cephalic vein
palpatable in an obese pt

chlorhexidine gluconate for patients that are allergic to betadine/ iodine
Length of needle commonly used in venipuncture 1 ince (up to 1.5")
