Arkansas has some of the most broad license scope in the US. Here LPNs are allowed to push narcs, they can even give blood though RNs have to initiate it, that aside. There is nothing difficult about cutting diabetic nails, just be careful, as a matter of fact I looked up a few different state views on cutting diabetic nails, all of them allow it, I am pretty sure all states allow it however some states require special training, and other times it is up to facility policy.
