Final answer:
The activity that distinguishes an advanced practice registered nurse (APRN) from other RNs, according to the ANA (1995), is the ability to prescribe medication.
Step-by-step explanation:
According to the American Nurses Association (1995), the activity that would distinguish an advanced practice registered nurse (APRN) from other registered nurses (RNs) is prescribing medication. Activities such as administering vaccinations, performing routine physical exams, and assisting with surgical procedures are all tasks that can fall under the direct supervision of a registered nurse. The APRN, however, has a broadened scope of practice that includes the ability to prescribe medications, which is typically beyond the scope of practice for a standard RN. The focus on providing specialized treatments such as dialysis involves skills such as reviewing patient history, assessing and responding to patient needs, and monitoring medical procedures, but prescribing medication is an exclusive activity that sets APRNs apart from other RNs.
