These are standard doses of all these medications. Its the dose of tylenol often used in the hospital and wasn't dosed every 2 hours it was dosed once. For the opiates we either give 1 or 2 pills, here they gave 1. Perfectly reasonable.
My point is I don't see that replacing opioids in this case is really useful. I'm happy to admit I don't know the answer here but I'm skeptical that people going to the hospital and getting a single 5mg percocet/vicodin or even a 3-4 over ~8-12 hours are really at risk of addiction.
For 24/7 dosing that acetaminophen/ibuprofen combo is only safe once every 6 hours which from my experience is way too long for acetaminophen. Even on every 4 hours I find the last 1 hour is definitely very noticeable.
