A nurse is caring for a patient after bariatric surgery. What is the priority nursing action when initiating oral fluids?

Choice A rationale Giving crackers with water is inappropriate for the initial phase of oral intake after bariatric surgery. The new gastric pouch is extremely small and sensitive, and solid foods like crackers can cause irritation, blockage, or stretching of the surgical site. The dietary progression must strictly follow a clear liquid protocol before moving to full liquids and then pureed foods. Introducing solids too early increases the risk of staple line leaks or severe gastric distress and vomiting. Choice B rationale Monitoring for nausea and vomiting while providing sips of clear liquids is the priority because the surgical procedure significantly reduces stomach capacity and alters digestion. Small sips, usually restricted to 30 mL at a time, help prevent overwhelming the small gastric pouch. Nausea and vomiting are early indicators of intolerance or potential complications such as edema at the anastomosis. Constant assessment allows for immediate intervention and adjustment of the intake rate to ensure patient safety and comfort. Choice C rationale Starting with 120 mL of water per hour is too much volume for a patient immediately following bariatric surgery. The typical capacity of the newly created gastric pouch is only about 30 mL. Consuming 120 mL in an hour could lead to overdistention of the pouch, causing pain, nausea, and potential damage to the surgical sutures or staples. Patients are usually instructed to sip very small amounts, such as 30 mL over the course of an entire hour. Choice D rationale Providing fluids through a straw is contraindicated after bariatric surgery. Drinking through a straw causes the patient to swallow excess air, known as aerophagia. This air can fill the small gastric pouch, leading to significant abdominal discomfort, gas pains, and a false sense of fullness. To minimize the intake of air and prevent distention, patients are encouraged to sip directly from a cup or use a small spoon to control the volume of liquid ingested.
