i have been in and out of management positions a long time. one thing i can tell you is that this new don would not be doing something this drastic
with the consequences
you mention without the approval of whomever she answers to in the chain of command. so, from that perspective i think you are all pretty much fated to your doom on this. as several other posters have already mentioned, it is very common for schools to put a 90% passage requirement on these med calc tests or they dismiss students from their nursing programs. and, if you think that is harsh, i can tell you that many employers also do the same during their orientation programs of new grads and new hire rns. if they can't pass a medication test after two or three tries, they are dismissed as employees before they even make it to the clinical floors where they were hired to work! so, this subject is not going to go away and you will most likely re-visit it again every time you start a new nursing job in the future.
i don't think it's fair of you students to stress out the other instructors about this. first of all, their allegiance is really with their employer, the college, if they want to stay employed. they are only trying to remain sympathetic with you students. they knew this change was coming before you did and i would venture to say that many of them, despite what they display to you students, are actually in agreement with it. med calc is so-o-o-o important. if the prospect of flunking out after failing with below 90% on a test hasn't impressed the seriousness of this skill on any of you, then one has to wonder where your commitment to nursing really is. patient lives hang on the edge of your ability to do these calculations—and you will do them on a daily basis at work as an rn or lpn. if you accidentally kill or cause harm to a patient because you calculated a dose incorrectly. . .it will be too late to learn what you should be learning today.
here are links to posts i made recently for people looking for practice med calc problems. i urge you to explore them and work these problems. there are plenty there to keep you busy. if you have trouble post a message about the particular problem here on the student forums (not the regular nursing forums) and you will get help from other students.
here is a link to a thread on dosage calculation help on the nursing student assistant forum that you should also check out:
i sincerely wish you good luck on your second time around with the test. welcome to allnurses!
