WHOA Veronica !
It takes 3 to 4 days for the FULL effect of a dose change to 'settle out' so changing dose after only 2 days will almost GUARANTEE a wildly swinging range of INR.
Dosing is really based on a WEEKLY basis. Are you saying the pharmacist told him to go from 2 mg every day to 1 mg every day? That would be a 50% reduction, WAY TOO MUCH of a change. If this is the case, I would suggest he get tested 3 or 4 days after the change. My guess is that his INR will then be too LOW (and if you see that same pharmacist, he will recommend too much of an increase and on and on and on.... sorry, but the sad fact is some people simply don't know how to properly manage Coumadin. Find a GOOD Coumadin Clinic ASAP and let them be your guide.)
When a small change is needed, the WEEKLY dose is usually adjusted by 10% spread over the whole week.

BTW, a few drops of blood from a nose bleed (or anything else) is TRIVIAL. That could be caused by dry air, even in someone NOT on Coumadin.
Here is another 'rule of thumb' guideline related to rectal bleeds. Pink on tissue, NOT SERIOUS. Pink in the commode water, call / see your Doctor. Heavy RED in the commode water, get to the ER ASAP. This probably can be generalized to any type of bleed. For cuts, use gause and PRESSURE.
Being a Heart Patient takes some 'getting used to' with a New set of Normals. One of my favorite sayings is "Heart Disease isn't for Sissies!"
Another saying (from Al Lodwick, our Coumadin GURU) is that "It's easier to replace Blood Cells than Brain Cells" which means that it is better to have a slightly higher INR (>4 or 5) and possible bleeding than to have too LOW an INR (<2)and a possible STROKE.
