A nurse is administering an intermittent enteral feeding through a client's NG tube. During the instillation, the client reports abdominal cramping and nausea. Which of the following actions should the nurse take?

A. Replace the NG tube.: There is no indication that the NG tube is malfunctioning or misplaced in this case. The cramping and nausea are more likely related to the feeding itself, not the tube. B. Lower the head of the bed to 15°.: Lowering the head of the bed would increase the risk of aspiration. The head of the bed should be elevated during enteral feeding to reduce this risk. C. Slow the rate of formula instillation.: Abdominal cramping and nausea during enteral feeding can occur if the feeding rate is too fast. Slowing the rate allows the stomach to better tolerate the formula and can alleviate symptoms. D. Chill and readminister the formula.: The temperature of the formula should not cause the cramping or nausea. Feeding should be administered at room temperature or as directed by protocol, and re-chilling it is unlikely to help with the symptoms.
