hi guys i just got an offer which i accepted as an acute dialysis RN at davita. my training starts in 3 weeks. i got the email, it states that i have to do the drug test, background checks, etc. and the main thing that i am concerned about is that i have to take a standardized math test which i have to get 90% correct. can someone please give me an insight about this topic? like examples of these standardized math test questions?
