Will I be fired?

Did you get the order or put out communication so the provider was aware? I did not use restraints much on my unit, but something like this would not bother my providers. They'd much rather know staff was safe then in harms way.

When I worked as a sitter the nurses would often get restraint orders after placing them too. It almost always at their discretion what type of restrains would be used (within reason).

As she should have.  And yes, I think you are overreacting.  If everyone that applied an incorrect restraint was written up, there would be few nurses not involved in the disciplinary process.

... Any guidance would be appreciated

As one of my facility's restraint champions, I always advise nurses that in these situations staff and patient safety should be your primary concern.  You successfully  accomplished this goal.  The only suggestion I think I could make would be to review your order as soon as restraints have been applied and the situation is somewhat more controlled.  Other than this, applying restraints on a patient acting violently towards staff is a stressful situation at best, and I think you handled it appropriately. 

Good job, and best wishes.

Follow up is important no matter whether it is time for your shift to end. Tie up the loose ends ,[sorry ,no pun intended ].

you do not want any phone calls on your day off, that the family came in and complained,,..and so on.
