Accidentally Bumped My Cast While Icing My Face On Day 1 After Rhinoplasty?

It is unlikely that any damage was caused. It would be best to speak with your surgeon and have him/her examine the area to ensure you are healing properly. I hope this helps, and I wish you the best of luck. 

In short the answer is NO

It is very unlikely that you would have moved the bones with the bump on the nose. The splint is there for that exact reason , to guard the bones against accidental knocks and bangs.

I hope that reassures you to some degree

It is unlikely that you have actually caused
damage to your recovering nose. Accidents are not uncommon in the first days of
recovery, but it is rare that substantial damage will ensue from such minor
trauma like you have described. I recommend that you make an appointment to see
your surgeon in person to discuss the incident. He or she knows your condition
best, and can ensure that everything is going smoothly with your recovery to
give you peace of mind.
