Regarding the X-Ray issue: It could either be a momentary lapse of attention, an isolated scenario, or it could be that that person has the history of being careless in his/her job. In either case, it is a good idea to report this to the authority. You should write a letter to the hospital's administration and possibly to the relevant medical board. Be sure to keep a copy. This is not a matter of being vindictive, even more so, it is not about that X-ray technician; it is to make sure that this kind of error does happen again (I am sure it will, but by drawing attention, it is less likely). I read somewhere that hundreds, even thousands, die in the United States due to negligence in hospitals. We need to be vigilant and be vocal about it. If the manufacturing companies like GE and Motorola can implement Six Sigma to virtually eliminate all process faults, it is more imperative that such practices be in use at medical institutions. Finally, you should be commended for being alert. It is incumbent upon parents to be ever so vigilant when anything is being done to their kids.
