Nostril bleeding balloon

Patient: My dad was taken to the e.r last night with a nosebleed, he has been on blood thinners(plavix) for 3 weeks and they assumed that was the issue. they tried to pack it, cauterize, and pinch it but it did not work. they then put in a balloon to stop the bleeding. it has since stopped but he still has the balloon on until Monday when the E,N and T doctor will remove it. Is that the customary protocol? Monday is 4 days away??? This is very uncomfortable and he can only breath form barely one nostril!

Doctor:
