I took the PN a year ago in March. I had one drug question and it was a specific drug. It was one I had never heard of and I told myself to remember it so I could look it up when I came out of the test but of course I forgot it almost immediately. I had no other questions even remotely related to drugs. I passed with 85 questions.
I took the RN test a week ago Tuesday and I had two drug questions, again they were drugs I never heard of and they were names that didn't give a hint. By that I mean they didn't end in olol or pine or something that would have helped me figure it out. I just did best guess.
To be honest, I did not study drugs for either test. I worked as an LPN for a year before taking the RN and I passed a lot of meds. None of those were on the test.
