Just want to get normals for pt/ptt/INR
At what minimum level would you d/c the heparin, coumadin.
Normal INR: 0.8-1.2. Coumadin d/c at level 3.0 and and start if INR 1. This is example and don't know if right.
And why is thereapeutic range 2-3 when normal INR is 0.8-1.2. Shouldn't the target of therapy be 1. That is normal. 2-3 is not normal. Does a normal INR cause clotting? Or is 2-3 a better value to prevent clots?
Some people saying INR is for coumadin, and some say PT. I know INR is a ratio of PT. But on my tests in school it was usually INR for coumadin.
So if nclex asked a question when to d/c coumadin based on labs, and the answers were a. pt b. INR
which one would it be?
All these kinda confusing. I think examples are best. Thanks
