Literally, some of them needed a pencil and paper to calculate: The patient needs 500 mg. Each pill contains 250 mg. How many pills will you give?

That is a really scary thought! It's like the kids who work at a fast food place.

Tried handing the kid the two pennies one time and he had no idea why!
