Yes, pain control is a top priority. Pain interferes with rest, causes anxiety, and drives patients to stress-related behaviors. In the hospital I had worked at, we had a tiered pain med system where we gave narcotics for a reported pain level of 5+ and non-narcotics for 4 or less. I had a patient who was on chronic pain medication request an NSAID although his pain was a 7, but that was his call and I made sure he undersrood that there was no need to tough it out if he didn't want to.
In home care pediatrics, I do a lot more non-pharmacological interventions for pain (though there are always PRN orders for Tylenol/Ibuprofen). This is often because my kids are non-verbal and already on so many other heavy medications. Heat, cold, change of position, distraction, holding/cuddling, massage, music can all help too. I had one infant with an anoxic brain injury that could be instantly soothed from minor pain by swinging her rhythmically side to side.
I agree with the other commentors as well. Screw up your courage and report. I saw neglect in my nursing school days too, and it's never okay. Many nurses think that students can't or won't call them out, but we can and we should.
