I guess Mom has to have her blood drawn every day for the next 5 to 7 days and Dad has to give her 2 shots a day into her stomach due to her INR levels, which has something to do with your blood clotting abilities. They don't want it too high or too low.
But she is on her way home now and is happy as can be.
Sometimes they can have their INR level checked by simply doing a finger stick, like a diabetic, and put the test strip into a INR meter to determine the level. If her INR level gets too high it will take longer for her blood to clot and if it gets too low it will clot too easily. I'm no doctor by a long shot but this was just something we touched on in my EMT/Paramedic classes. But regardless of that, thank goodness she's on her way home.
