Hey there, I totally agree with you. I think both of you should have been in that room to help resolve this situation. You were important in the scenario because you could've provided any valuable information that may be needed on anything that happened throughout the night and you having had the patient for an entire shift know more about the patient than Nurse A. But it was also Nurse A's responsibility because she is this patients new nurse and since she has already gotten report she needed to be the primary one in that room with the patient whether she was in the middle of report or not. Good Luck with your new career!
