My understanding has always been that it's "all or nothing," as the pharmacist told your LPN -- you either give the med or you don't. The client can refuse the med, but then s/he is refusing
all the med. If the client is choosing to only take a partial dose, and you are
giving only a partial dose, then one or the other of you is
prescribing, which neither of you is legally authorized to do. And, as you note, the best nursing response is to consult the Rx-ing physician about getting the dose changed to something the client is willing to take.
Now, if you're giving the med and the kid swallows one pill and then refuses to swallow the other, there's nothing you can do about that after the fact

, but I would document that as an occurrence and, the next time, wouldn't give the med at all if the kid's not willing to take the entire dose.
