A Licensed Practical Nurse (LPN), called Registered Practical Nurse (RPN) in Ontario, is a healthcare professional who provides nursing care under the supervision of registered nurses or physicians. LPNs complete shorter training programs than registered nurses, typically 18-24 months of post-secondary education. They perform duties including administering medications, monitoring patient conditions, providing basic care, and assisting with treatments. LPNs work in hospitals, long-term care facilities, clinics, and home care settings. Provincial regulatory colleges license LPNs and set practice standards. LPNs are essential members of healthcare teams, particularly in settings caring for seniors and those with chronic conditions.
