A client who had bariatric surgery 2 months ago is admitted because of vomiting and inability to tolerate food and liquids. The client is pain free. Which intervention should the nurse include in the client's plan of care?

A. Maintain the client on an NPO status: After bariatric surgery, vomiting and the inability to tolerate food and liquids could indicate complications such as gastric outlet obstruction or stenosis. Maintaining NPO status allows the gastrointestinal system to rest while the cause of the symptoms is investigated and treated. B. Determine if the client is over-hydrating to feel satiated: While over-hydration can cause discomfort, the immediate concern is the client's inability to tolerate food and liquids, which may suggest a more serious issue. C. Administer daily vitamin supplements: While vitamin supplementation is essential after bariatric surgery to prevent deficiencies, it does not directly address the current issue of vomiting and inability to tolerate food and liquids. D. Encourage positive self accolades for dietary adherence: Though reinforcing positive behavior is important in long-term weight loss management, it is not the priority at this moment. The immediate focus is addressing the client's symptoms and ensuring they are medically managed.
