I don't think giving nurses unrestricted access to narcotics is giving them 'freedom to do their job' because a valid part of a nurse's job is controlling access to narcotics. It's not a medical need, but it's an operational and societal need. Same with whatever a CT tech would do away from the controls. I think this is more accurately a descoping of the job to improve throughput.
Depends how you define the job. A different interpretation is that the job of a medical professional is to improve the health of their patients as much as they can. Normally this is done by frequently having someone/something more specialized ensure perfect care for the task at hand, but on this night that might take too long, so the best way to improve the health of the patients was to abandon protocol and do the best they can as fast as they can.
