The first step in becoming a nurse typically involves obtaining the necessary education. Most nursing programs require a high school diploma or equivalent, with coursework in subjects like biology, chemistry, and math. Prospective nurses can then pursue a Licensed Practical Nurse (LPN) certificate, an Associate Degree in Nursing (ADN), or a Bachelor of Science in Nursing (BSN). Each of these pathways has its own set of prerequisites and duration, ranging from one to four years.
