Answer is c. Keep the head of the bed raised while the tube feeding is infusing. The client has a gastrostomy tube (GT), which is a tube inserted through the abdomen into the stomach for feeding purposes1. The PN should instruct the UAP to keep the head of the bed raised at least 30 degrees while the tube feeding is infusing, to prevent aspiration of the feed into the lungs2. Aspiration can cause pneumonia, which is a serious complication that can be fatal3. a. Raising the entire bed while bathing the client to reduce back strain is not the most important instruction, because it does not address the risk of aspiration. The PN should also consider the client’s comfort and safety when adjusting the bed height. b. Reporting any drainage observed around the GT insertion site is not the most important instruction, because it is not directly related to the tube feeding. Drainage may indicate infection or leakage of the feed, which should be reported and managed accordingly. d. Using plenty of pillows to position the client on the side after bathing is not the most important instruction, because it is not specific to the tube feeding. Positioning the client on the side may help prevent pressure ulcers and improve circulation, but it does not prevent aspiration.
