3-8%
33
What side is cryptorchid more common on?
Right cRyptorchid
34
True or False? A right shift on the O2/HgB dissociation curve will cause a higher affinity for oxygen to hemoglobin?
False Shifting the curve to the right Reduces affinity of HgB for oxygen "Right reduces"
35
True or False? A left shift on the O2/HgB dissociation curve will cause a higher affinity for oxygen to hemoglobin?
True
36
True or False? A right shift on the O2/HgB dissociation curve will cause less oxygen at the tissue level?
False Because "Right shift Reduces" affinity, MORE oxygen is left in tissues
37
Generation of fibrin polymers that stabilize the platelet plug into a mature thrombus is called what?
Secondary hemostasis (it is the cascade)

What diseases can you treat with FFP? What should you not treat with FFP?
Yes FFP = coag factor abnormalities, vWD (though not as good as cryoprecipitate), hypoproteinemia No = fibrinogen abnormalities, heparin related bleeding (the antithrombin in the plasma will be activated by the heparin in circulation)
