The test results came back a few hours ago. The doctors were right, Mom had some sort of blood clot or something. I think it had something to do with her lungs or around her lungs. The nurse did not have many details by the time I left.
I don't think it's very serious.... they have her on a blood thinner.
They will keep her on that until the next surgery. (Which they still don't have scheduled).

I am home now, but Dad is staying another night. Mom still has a fever and is not completely stable, so he didn't want to leave.
She has been awake all day, responding and giving us smiles and facial expressions. She tried several times to tell us something, but we had a very hard time understanding. All she can do is mouth the word and wait for us to guess. Very frusterating.
They never got the breathing tube out... they just have to wait until she is stable.
Pray for deep sleep tonight; she had a tiring day.
We are so encouraged that she is awake and can hear us!
