Good for you and your organization! However I know of too many nurses and ancillary techs that have never had a chemistry,pharmacology, or anatomy course with a difficulty level greater than the Cliff Notes level.
It would expensive to require everyone involved in healthcare to know everything. Clearly, pharmacists have to know chemistry and pharmacology. And, with healthcare moving beyond re-setting of bones and such, and involving more and more drug therapy, we have been re-visiting the expectations of nurses. I think this is why we are seeing the bachelors degree required for nurses, instead of merely the associates degree, with the B.S. in Nursing involving chemistry and pharmacology courses appropriate to nurses. The investment required for a B.S. in Nursing generally pays good dividends in terms of a high-paying job.
