A client is being discharged and will continue enteral feedings at home. Which of the following statements by a family member indicates the need for further teaching?

Diarrhea is a complication of tube feedings that can lead to dehydration. Diarrhea may be the result of hypertonic formulas that can draw fluid into the bowel. Other causes of diarrhea may be bacterial contamination, fecal impaction, medications, and low albumin. A consistent weight gain of more than 0.22 kg/day (1/2 lb/day) over several days should be reported promptly. The client should be evaluated for fluid volume excess. Elevating the client's head prevents reflux and thus formula from entering the airway. Bacteria proliferate rapidly in enteral formulas and can cause gastroenteritis and even sepsis.
