Grandma in the Hospital

Grandma is in the hospital. Yesterday she passed out and fell and cut her head. the cut was about 3" long and down to the bone. She feels like she is about to pass out a lot but has time to hurry and sit down. But not this time....
They put her in yesterday and are keeping her in today and tonight to run some tests.
Yesterday they did a cat scan and saw that she has had some mini strokes, but not recent enough to have been what happened this time.
They also did a EKG and it looked fine. Today they will do a bunch more tests.
