Again, my point was this nurse might be under instructions not to call ambulances; under political pressure at work, as I was.
And as I stated earlier, the call depends on the type of break, how it happened, and the age of the child.
And as I stated earlier, she could have called the parent, informed them, and asked for directions from them, ie. the parent could have phoned an ambulance. For all the nurse knew, or didn't know, that child could have had other issues not reported by the parents.
Not saying an ambulance WAS called for, but if I had been the nurse, I would have covered all the bases.
