Can Nodes Be Recycled?

Ignoring adventitious budding, new shoots typically come from nodes along a stem. But is a given node/bud one-and-done, or can a node sprout another bud if:
A) it already had a branch that was cut off
B) the original bud sprouted but failed to produce a viable branch
C) the original bud was rubbed off before it developed
D) any other way I may be missing for a bud to be "used up"

For context, I'm personally only concerned with deciduous trees (namely maple, Chinese elm, and hornbeam), but feel free to comment on coniferous or other evergreens for others' sake.

Those should come back, but you shouldn't be in this position.

Old nodes will definitely keep producing new buds if necessary. I frequently chop Japanese maples back to the base of a shoot if it has long internodes. New shoots just keep on emerging.
In option B where a bud fails there may be other factors at work that could also prevent new buds growing. Otherwise no problem for most deciduous species.
