Medical surgical nurses provide basic medical care to patients of all ages suffering an extensive variety of ailments. The Academy of Medical-Surgical Nurses (AMSN) is the major professional organization for adult medical-surgical nursing. Registered nurses can choose between two medical-surgical certification exams. The Certified Medical-Surgical Registered Nurse (CMSRN) credential is maintained by the Medical-Surgical Nursing Certification Board (MSNCB) and endorsed by the AMSN. The Medical-Surgical Nursing Certification Exam (RN-BC) is maintained by the American Nurses Credentialing Center (ANCC). Both are accredited by the American Board of Nursing Specialties (ABNS). The U.S. Bureau of Labor Statistics predicts excellent, overall job growth for registered nurses.
