An MSN is a graduate-level degree that prepares nurses for advanced clinical roles, such as Nurse Practitioner (NP), Clinical Nurse Specialist (CNS), Nurse Anesthetist (CRNA), and Nurse Midwife (CNM). MSN programs typically require 1-2 years of study and include both coursework and clinical practice. Some programs offer specializations in areas like Family Practice, Pediatrics, or Mental Health.
