Man of Honour
Too many people are ready to blame the person/people rather than understand the true root cause of the issue. I'd suggest that the problem/issue was the process which allowed an unqualified nurse to work in such an environment, or the training method isn't suitable. There has to be a process for every step in everything we do in life - a process is just a set of actions necessary to achieve the outcome desired. If those processes aren't review or controlled, you will get these problems.
Having said that, had I not been correctly trained, I would not have touched any of the buttons on equipment I didn't understand. Furthermore, in this instance the management team should have ensured they had the right person for the right job - in this case, either the training or recruitment or assignment process had broken down which led to an unsuitable person being able to do something like this.
Eitherway it's tragic, and I'm not trying to absolve the nurse or management of any culpability - what is done is done, however I'd want to ensure that the processes are reviewed, and any flaws in the processes have controls in place to ensure that this mistake doesn't happen again.
