Licensed Practical Nurses (LPNs) are an essential part of the healthcare system responsible for providing patients with basic health care. In order to become a Licensed Practical Nurse (LPN), students will have to complete certain educational and licensure requirements. The first step of the process is completing your high school diploma and applying to an LPN program in a community college or a vocational college. Once you have completed the training program, you will have to pass the NCLEX-PN exam. After taking the exam, the results would be available within 48 hours. If you clear the exam, the State Board of Nursing will mail you your license.
