Take this for what it is worth to you...I am not a smart-ass, I am not trying to blow smoke. I've never claimed to know how to treat a patient with an INR of 13.2, that's the doctors job. It is my job to know that a pt with an INR of 13.2 should not be taking ASA, Plavix and Coumadin on a daily basis until the INR comes down to a therapeutic level. She was taking 8 mg QD.
I ask you....Should I have left this patients home knowing what her INR was and what she was taking and not say anything, continue to let her believe she should continue on all three? What kind of nurse would I be?
Enough already. Coumadin is the only medication that would effect the PT/INR. It does not matter if the pt is taking ASA or Plavix -- it will have no bearing on PT/INR. This is the point these guys were getting at.
If the pt is supratherapeutic on Coumadin, this can be corrected by stopping the medication and giving Vit K and/or FFP depending on clinical judgement and the situation at hand (ie. acutely bleeding, going to the OR, etc).
PT/INR is only useful for Coumadin dosing. You can determine if the pt is at an efficacious dose of ASA or Plavix by doing platelet mapping or bleeding time.
