It is potentially, but as cheslea says you need to keep your head and start preparing yourself how to handle the situation.
How long do you have till the hearing?
Have you taken any advice?
You need to understand what it means.
What they are looking for.
The procedure
Then you need to start preparing a written statement on how to best state your case whilst avoiding various pitfalls.
Normally thats where have a lawyer, but anyone who is capable of objective analysis and a competemnt writer is ok.
Famiiarise yourself with the information on the links below amd that should give you an idea of what to expect, why they are concerned and what they are looking for. Forging a signature is serious because it calls into question your honesty and integrity.
How do they know you arent the sort of person to forge medical data, steal drugs, give false testimony? People need to be able to rely on your honesty without question otherwwise it all falls apart and you are more of a liability if other health professionals or pateints cannot trust you.
You are going to have to come up with a reason about why you did it, that it was a one off [ if it was], that you now understand the significance and you would like a second chance. You hadnt thought about the woder implications, but have been in contact with the RCN and re-read your onligations and expected standards of being a nurse and see how wrong/ stupid it was and would never do anything like that again. You are sorry , you let yourself, the uni, and colleagues down, but still believe you have what it takes to be a good nurse if given the chance
Do not fight or make excuses, but you can defend yourself in other ways through contrition and thoughtfulness. Basically withput them needing to read the rioy acy yo uoi, you cna already show you have learn your lesson.
I would do something along those lines.
Dont be a child
You are aiming I think for a written warning.
SU tend to be quite busy so they can give you an opinion, but its unlikely they will represent you or they cam offer you much more than one or two appointments.
Take someone with you for moral support although because it is at uni then the format may differ slightly from a full hearing.
You can talk to the RCN helpline.
