Advanced practice registered nurses; revise collaboration requirement.

SB 2450 amends Mississippi's nursing law to exempt certified nurse practitioners, certified nurse midwives, and clinical nurse specialists (all advanced practice registered nurses) from needing a collaborative relationship with a physician after completing 3,600 practice hours. The bill allows these nurses to count hours worked before the law's effective date toward the 3,600-hour requirement. It also updates definitions to include advanced practice registered nurses in the law's purpose, disciplinary actions, and scope of practice provisions. This change would reduce regulatory barriers for experienced advanced practice nurses in Mississippi.
