Basically for the Naplex I had a lot of questions on HIV and opportunistic infections related to HIV/AIDS. Make sure you know all the current guidelines for the treatment of all. Also know the ADRs from all HIV/AIDS medications. I also had a lot of calculations, not kinetics problems. Make sure to know all your brand to generics. A friend of mine also had chemo on hers.
on the MPJE, the most is the controlled substances act, know what your state has for that. Also read over the pharmacy practice act for your state so you are familiar with that.
