Every nurse should physically trace each tube to its receptacle. If there are two tubes in the vicinity but not even in proximity, extra care should be taken to trace the tube tactilely.
Yes, indeed, that is how this is supposed to work. Those are the rules. You don't know how very relieved I am to know that if I ever get killed by this sort of human error someone has assigned responsibility right where it belongs!
OTOH, you'll never see me successfully hooking up a CO2 regulator unto a nitrogen tank or a helium tank. This is not because I'm a genius or because I never make mistakes but because the parts don't fit together.
The government-protectionist tone here ("Critics say the tubing problem, which has gone on for decades, is an example of how the FDA fails to protect the public.") is absurd and gives you NO excuse to shed the responsibility for your actions.
So you want to blame private industry, instead? Who gives a damn? Six of one, half a dozen of the other.
Seeing this as some sort of political statement is really not particularly productive. It is what it is and what it is is a problem with a trivial solution (design parts which are not supposed to ever be joined together so that they do not fit together) with no drawbacks and which has the potential to totally eliminate the grossest manifestation of the problem altogether.
The solution for this problem will, of course, not totally eliminate related problems of right tubes being connected together but having the wrong stuff or the wrong concentration of stuff (i.e. wrong IV drug in an IV line or too much or too little of the right drug). Such has to be dealt with by other means (changes in training, changes in working conditions, explicit checklists, etc.).
