The ALF may choose to provide, but is not required to provide, intermittent nursing services. Some nursing services may be done through registered nurse delegation to a nursing assistant or home care aide. A licensed practical nurse may provide nursing care in an ALF within the licensed practical nurse's scope of practice under the direction of an authorized health care practitioner or under the direction and supervision of a registered nurse. Only a registered nurse may delegate nursing activities to a nursing assistant-certified (NA-C), nursing assistant-registered (NA-R), or home care aid-certified (HCA-C) in an ALF. See the RCW 18.20 Assisted Living Facilities and WAC 388-78A Assisted Living Facility Licensing Rules for more information.
