advanced practice nurse (APN). RNs and APNs mutually have the same mission to competently
and safely care for the patient, but their scope of practice and roles are different. A master's
education trains APNs to provide assessment, diagnose medical problems, order diagnostic tests
and equipment, and order medication prescriptions (National Council of State Boards of Nursing,
2020). There are different but similar steps to transition from an RN to an APN. The purpose of
this paper is to study the four APN roles and how it differs from educational preparation, work
environment, and describe my journey to transition from an RN to a certified nurse practitioner.
Four APN Roles
Since the birth of the APN role over half a century ago, practicing APNs continues to
surge as they are expecting to be vital members within the health care system (Zhang et al.
2020). APNs have four focused roles which are certified nurse practitioner (CNP), clinical nurse

role description.
