Final answer:
To decrease aspiration risk for a client receiving enteral feedings through an NG tube, the nurse should place the client in a semi-Fowler's position and check the NG tube placement before each feeding. Flushing the tube and the formula temperature are less critical to preventing aspiration.
Step-by-step explanation:
To reduce the risk for aspiration in a client receiving intermittent enteral feedings every 4 hours via an NG tube, the nurse should engage in several best practices. One of the most effective methods is to place the client in a semi-Fowler's position, which involves having the client sit at a 30 to 45-degree angle. This position helps to reduce the risk of aspiration by using gravity to keep the stomach contents from flowing back up the esophagus. Additionally, it is essential to check placement of the NG tube before each feeding, rather than once per day, to ensure that the tube has not been displaced. This often involves aspirating stomach contents and measuring pH or using another verification technique prescribed by hospital policy. Flushing the tubing with 20 mL of water prior to each feeding can help maintain tube patency but is not directly associated with reducing aspiration risk. The temperature of the formula, whether chilled or at room temperature, is also not a primary factor in preventing aspiration.
