Am I wrong?

Ok, I am a new CNA. I have been working for about a month in a hospital. I was asked by one of the other aides to help her rotate with a one to one patient she had. So, I did. I did my work, relieved her and did one to one for about an hour, and she came to relieve me and I took care what I needed. About 9:30 I come in the to do the one to one. So, everything is fine then 11:00 rolls around (SHIFTS END AT 11:00). No sign of the aide to let me know what I am going to do with HER patient. Then 11:20, the charge nurse advises the patients nurse to put restraints on the patient or a bed alarm and advised me to go home, I dont have to stay. Anyway, the aide for this patient went home...left at 11:00 without letting me know or even asking the charge nurse on what to do.........

I am very, very upset about this!!! I would never do this to another aide. I would of found out from the nurse and charge nurse at 10:30 on what should be done and then I would of relieved the aide who was helping me and I would then handle the situation myself since it was my patient. Please let me know if I am wrong?? I am going to confront the aide about this and see what she has to say about it.
