Different at every school, but I'm sure a good 90% is scenario questions. Such as the second poster said.
Alot is knowing the different measurements and being able to correspond them with other amounts. Such as 1ml = 1cc. 30cc = 1 tsp (I think - been a while). And 60 grains = 1 mg (could be wrong on this too lol - sorry it has been a while and I've slept since then).
Also knowing that 2.2 pounds = 1 kg, is crucial.
I was taught the 'football' method to figure out dosages. Not even sure that is the right word, but it had something to do with football. Sorry I'm so vague. I think my brain is frozen due to my thermostat doesn't seem to be working right and I'm already sick. *sigh*
So a scenario question would be something like:
You have a 10# baby, the doctor has ordered 10mg/kg of xyz antibiotic, it comes in strength of 1000g/1ml. 1. What would you dispense? and is this a correct order that the doctor gave you? If not what would be the correct dose.
I really pulled this one out of my behind, because it is not a real antibiotic and it has unrealistic dosages. But it gives you an idea of the format.
Good luck - I sucked at math in school, but I proudly have an RN behind my name so apparently I did something right
