Nursing Implications
Prolonged stasis from vasoconstriction secondary to the tourniquet can alter values.
Abnormalities in RBC size may alter Hct values

White Blood Cell Count (WBC)
Nursing Implications
Anesthetic, stress, exercise, and convulsions can cause increased values
Drug therapy can decrease values
24-48 hr postpartum: A count as high as 25,000 is normal
