A nurse is preparing to administer an enteral feeding via an established NG tube. Identify the sequence the nurse should follow to initiate the feeding. (Move the steps into the box on the right, placing them in the selected order of performance. Use all the steps.)

Choice A rationale Verifying tube placement is the initial critical step to ensure the feeding is delivered into the gastrointestinal tract and not the respiratory system, thereby preventing aspiration. Methods for verification include pH testing of aspirate (target pH ≤ 5.5), and radiographic confirmation is the gold standard, especially after initial placement. Choice B rationale Checking the residual feeding contents before administering a new feeding is essential to assess the client's tolerance to the previous feeding and prevent overfeeding, which can lead to complications like abdominal distension, nausea, vomiting, and aspiration. A high residual volume may indicate delayed gastric emptying. Choice C rationale Administering the feeding follows confirmation of tube placement and assessment of residual volume. The feeding should be administered at the prescribed rate and volume, ensuring the client receives adequate nutrition and hydration. The client should be positioned with the head of the bed elevated at least 30-45 degrees during and for at least 30-60 minutes after feeding to minimize aspiration risk. Choice D rationale Evaluating the client's tolerance to the feeding is an ongoing process that involves monitoring for signs and symptoms such as abdominal distension, pain, nausea, vomiting, diarrhea, or aspiration. This evaluation helps determine if the feeding regimen needs adjustment in terms of rate, volume, or formula.
