No studies suggest that care is better in states that have more restrictive scope-of-practice regulations for APRNs than in those that do not. Yet most states continue to restrict the practice of APRNs beyond what is warranted by either their education or their training.

Depending on the state, restrictions on an APRN’s scope of practice may limit or prohibit the authority to prescribe medications, admit patients to hospitals, assess patient conditions, and order and evaluate tests. Box 3-1 provides an example of the variation in state licensure regulations, detailing examples of the services an APRN would not be permitted to provide if she practiced in a more restrictive state (Safriet, 2010). In addition to variations among states, the scope of practice for APRNs in some cases varies within a state by geographic location of the practice within the state or nature of the practice setting.
