Looking for some clarification on dose ranges for prns. Example...
If an order says 1-2 Vicodin q4 hrs prn for pain:
Can we give 1 tab at 8am and 1 tab at 10am? Or If we give one tab at 8am, do we have to wait until 12pm to give any more?
I've had a few different jobs as an RN and have noticed that there is a split between what nurses think. I'm looking for what's legal, what the order actually MEANS.
I was originally taught that if the MD order says you can give something q4h, you can't give it at any frequency other than 4 hours. (In the above example, the order does NOT say that I can give 1 tab q2h, but that I could give one or two tabs q4h.) As this was how I learned it, it's what makes the most sense in my mind. But my current DON just made a statement that you can give it at any time within the time frame as long as you don't exceed the maximum dose.
If anybody can actually give me a link to some research/evidence/proof, it would be much appreciated. I'd also like to hear some humble opinions
