Is the school registered nurse (RN) allowed to delegate enteral tube feeding and related tasks to the nursing assistant registered/nursing assistant certified (NA-R/NA-C) in daycares, preschools, or head start programs?

It depends. The school RN is allowed to delegate enteral tube feedings and related tasks such as stoma care, irrigation/flushing, aspirating for residual, and venting with a syringe or venting with a gastric venting system of a gastrostomy tube (G-tube), such as Percutaneous Endoscopic Gastrostomy (PEG) tube, Jejunostomy tube (J-tube), or Jejunostomy/Gastrostomy (J-G) tube, to the  NA-R/NA-C in a daycare, preschool or head start program but would not be able to delegate medication administration in these settings via an enteral tube.
