How do I help my daughter relax when she gets home?

My daughter was in a car accident with her friend a few days ago. She has a broken nose, two cracked ribs, bruises, cuts and had a mild concussion. The doctors are keeping her for a little bit longer and I want to make sure she is comfortable when she comes home. I got the things that I thought she would need (bandages, extra pillows, ect.) I heard when a person has a broken nose to get a saline rinse for them to use? I’m going to check with her doctor to see if it’s okay. What else can you suggest me to get for her? Thank you.
