Failed by one point!! Are you an RN now? How did you motivate yourself during that year to come back?
That's nursing school for you--a lot of them don't believe in rounding grades up or letting those at the very edge of passing slide across. If 90 is the grade required to pass, 89, 89.5 and 89.9 would all be considered failing. And yes, nowadays there are pharmacists and computers to do all the calculation grunt work...but they can make mistakes. Nor are they there are 0300 to help you calculate the amount of medication to give stat to someone that is coding.
Let yourself mourn for a day or so. It's OK to be sad, frustrated, disappointed, whatever you are feeling.
Then figure out where your weakness(es) are. You pointed out a few of them to start. You weren't sure of a formula (not sure which one as you didn't mention specifics) so make it a point to master that formula.
You also said you didn't read the instructions, so now make it a point to read the instructions thoroughly, underline or highlight any special things you need to know...and then reread the instructions again to make sure you really got it. It's easy to overlook a key piece of info...I've done it, most everyone has done it. We're human, after all.
If you can, see if someone who passed the class is willing to help you out. Also consider getting a med calculation workbook and/or looking up med calculation problems online and practice, practice, practice. The more calculation questions you practice, the more comfortable you will feel with them.
This will stop you from becoming a nurse only if you let it. You don't have to let it. You can do this.
Best of luck.
