A nurse is planning to administer an intermittent enteral feeding through a client's percutaneous endoscopic gastrostomy (PEG) tube. Which of the following actions should the nurse take?

Intermittent enteral feeding through a percutaneous endoscopic gastrostomy (PEG) tube is used to provide nutrition directly into the stomach in clients who cannot safely swallow. Safe administration requires proper positioning, tube patency checks, and prevention of aspiration or clogging. Nursing care focuses on maintaining tube function and reducing complications such as aspiration pneumonia, tube obstruction, and gastric intolerance. Correct technique ensures effective and safe delivery of enteral nutrition. Rationale: A. Elevating the head of the bed to 20 degrees is insufficient for preventing aspiration during and after enteral feeding. The recommended position is typically 30–45 degrees to reduce the risk of gastric reflux and aspiration. A 20-degree elevation does not provide adequate protection for airway safety. B. Withholding feeding if 50 mL of residual is present is not appropriate because this amount is generally within acceptable limits depending on facility policy. Small residual volumes are common and do not necessarily indicate intolerance. Routine practice focuses on trends in residuals and clinical signs rather than a single measurement alone. C. Positioning the client supine for 1 hour after feeding increases the risk of aspiration. Supine positioning allows gastric contents to reflux into the esophagus and potentially enter the airway. Clients should remain upright or in a semi-Fowler’s position during and after feeding to promote safe digestion. D. Administering 30 mL of water prior to feeding helps ensure patency of the PEG tube and reduces the risk of clogging. It also prepares the gastrointestinal tract for feeding and helps verify proper tube function. Flushing before and after feeding is a standard nursing practice to maintain tube integrity and safe nutrition delivery.
