Final answer:
The nurse should check the formula for intolerance when a client receiving intermittent enteral tube feedings experiences diarrhea. Other actions such as increasing feeding rate, using a smaller tube, or administering antidiarrheal medication do not address the potential root cause.
Step-by-step explanation:
If a client receiving intermittent enteral tube feedings is experiencing diarrhea after each feeding, it is important to identify and address the underlying cause. In this scenario, checking the formula for intolerance is a prudent first step. This action ensures that the enteral feeding formula is not contributing to the client's symptoms by being too hypertonic or containing ingredients that the client cannot tolerate. It is not advisable to increase the feeding rate as this might exacerbate the problem. Using a smaller feeding tube would not prevent diarrhea and is not relevant to the issue at hand. While administering antidiarrheal medication may relieve symptoms, it does not address the root cause of the diarrhea, which could be due to a formula intolerance or infection such as Clostridioides difficile. The nurse should work with the healthcare team to evaluate the situation thoroughly and consider testing if the issue persists, keeping in mind that conditions such as a C. difficile infection require specific interventions.
