God numbers are so fucking useless. Especially in psychiatry. The doctor's not gonna order opiates, they're just not. It's for like 30 dumb reasons that mostly boil down to addiction and 20 less dumb reasons that all boil down to "you're in the wrong place to treat whatever's causing that."
So I've got Tylenol and Motrin and unless you've got stomach bullshit or have a personal preference I'm gonna lead with the Motrin because it's stronger. So I'm gonna put in the number for whatever the order says that med is supposed to be given for and give it. The Motrin says your pain needs to be a 6 so your pain is gonna be at least a 6. The number is so irrelevant to what's actually going to happen that tbh it's kinda in the way.
And in the rare event that I do have an opiate available, your POSS score is way more relevant anyway.
