1. Both. Most were fill in the blanks for me but off the top of my head I had a CrCl that was MC and some other word problems that involved calculations were MC (ex. which strength/quantity of xyz antibiotic suspension is appropriate to fill this RX).
2. Both I had more generics than brands I would say. If anything I had brand names more often for drugs that you only see generic (ex. Lotensin for benazepril) and generic names for newer currently branded products (ex. Saphris/Latuda/etc)
3. I honestly forget, i barely had any mEq calcs and no mOSm that I remember. Generally your only going to see basic electrolytes that you should already know the valence for K/Na +1, Ca/MG +2 type stuff.
4. I had 1 or 2 questions regarding opiate conversions and it including a table with the specific ones in question.
5. A few, usually with something else to calculate like "how much of XYZ is added qs to make a 10% w/v solution." RXPrep calculations covered pretty much anything and everything that was on my test.
6. I did not have anything. But it did mention that "for this problem 1 oz=30ml at least once."
Only thing I left the exam confused/annoyed about was problems involving CrCl because they never give you an exact formula to use in terms of what the PT's weight is. I followed what RXPrep said but the answers never exactly maxed what they should. Maybe my calculator game was off *Shrug*
