Do you have to go to Kennesaw State University before you go to Kennesaw Nursing School?

I think the answer to your question is to begin with the goal e.g. and work back. A forensic pathologist is a very specialist occupation and therefore I am  sure that going down the nursing school route would not be appropriate. You would need to be thinking of a medical doctor/surgeon route which is much higher level.
Because you want to go to Kennesaw State University and you are in the planning stage of your education, why don't you speak with them, preferably see them because it is important to get this right, tell them what you ultimate goal is and ask for their detailed advice.
There are parts of this that you can work on yourself but there are important areas where you really do need help. Kennesaw will be delighted to help you I am sure.
Take care.
