Licensed Practical Nurse (LPN)
Licensed practical nurses (LPNs) are health care professionals who have completed twelve months to two years of training in anatomy and physiology, medications, and practical patient care. They have passed state and national boards. LPNs can perform simple as well as complex medical procedures, but must operate under the supervision of either a professional registered nurse (RN) or a physician. They can administer most medications, perform measurements (blood pressure, temperature, etc), and help with patient-care planning, surgery, first aid, and basic care.Reference: http://en.wikipedia.org/wiki/Licensed_Practical_Nurse
