Seriously....unless you are seriously academically lacking, it is probably just going to drain your bank account for little if any gain. These types of courses prey upon the slow, weak and stupid in our ranks based upon their fear.
Rule #1: Operate as though everyone around you is drunk, high, stupid, ignorant, oblivious, distracted or just a good ol' fashioned sadistic ***hole until given conclusive evidence to refute such beliefs in a given case.
Apply this as broadly or as narrowly as you see fit.
Precisely why if the patient may well have a reversible cause of their unconsciousness (re: hypoglycemia)? Bag the patient, push the D50 (or glucagon) and see if that gets their glucose level back up and if the patient comes around. If that does not work, then and only then, would i consider...
You do realize that a brain injury can occur simply from hypoglycemia right? This is one of those scenarios where you correct the problems you are confronted with and worry about sorting out what caused it later (if at all) since the patient doesn't have time for such pedantic academic exercises.
There's always a chance you failed. I doubt how quickly something comes (especially if it takes six weeks) is a valid predictor of success or failure and there is probably no conclusive data to say one way or the other. I guess you shall see what your n=1 experience will be.
By the way...
I might be a little brash, but it's not malicious, I assure you. Most people simply lack the ability or will to be critically self-assessing. My goal is to force people to do so for their own benefit, that of their patients and (potential) colleagues.
