IV compatibility question

[sistrmoon]

Maybe this is a dumb question(don't you love posts that start this way?) but if a med is compatible with NS, do you assume it is also compatible with 1/2 normal saline? I'm kind of a "by the book" girl and don't hang things together that aren't tested. But my coworker says if it's compatible with NS, it would also be with 1/2NS as it's just a different concentration. What say you?
