Can a wife of the patient who plans on staying with her husband for open heart surgery, shower in his room? He should be there for 5-7 days

Yes you can Joan

My wife stayed in room, but needed to get a room one so as not to go stir crazy.

Yes, you can

Yes

The patient might need to be kept in isolation immediately following surgery, but yes - family can stay with the patient and they can come and go 24/7

Indeed and surely, you can as the room is private for the patient and any relative or spouse and children can use as they may wish.

Absolutely, you can virtually move in.

Yes, they are great about accommodating the family.
