The nurse on the medical-surgical unit is caring for the client. Which of the following actions should the nurse take?

Nursing care for a client with confirmed small bowel obstruction requires prioritizing gastrointestinal decompression, fluid and electrolyte balance, and preparation for definitive surgical management. The CT findings of distended small intestine with absent colonic gas indicate a mechanical obstruction requiring an Exploratory laparotomy. Preoperative and supportive care aims to stabilize the client, prevent aspiration, reduce bowel distention, and prepare for surgery. Ongoing monitoring and maintenance of ordered interventions are essential to prevent complications such as perforation or sepsis. Rationale: A. Providing preoperative teaching is appropriate because the client is scheduled for surgery the next morning. Education helps reduce anxiety, improves cooperation, and prepares the client for what to expect postoperatively, including pain management, mobility, and recovery expectations. Even in urgent cases, brief focused teaching is an important nursing intervention to support informed care. B. Providing the client with ice chips is inappropriate because the client is ordered to remain NPO due to bowel obstruction and upcoming surgery. Oral intake can worsen gastric distention, increase risk of vomiting, and raise the risk of aspiration. Maintaining NPO status is essential to prevent complications and prepare the gastrointestinal tract for surgery. C. Starting the prescribed antibiotic is not appropriate as an immediate nursing action in this scenario because the antibiotic (cefazolin) is scheduled to begin at 0530 before surgery, not at the current time. Administering medications outside of the prescribed timing may interfere with surgical prophylaxis protocols. Medication timing must be strictly followed to ensure effectiveness and safety. D. Maintaining the nasogastric (NG) tube to low intermittent suction is essential because it decompresses the stomach and intestines, reduces vomiting, and prevents further accumulation of gastric contents. This helps relieve abdominal distention and lowers the risk of aspiration. Proper NG tube management is a priority intervention in small bowel obstruction to stabilize the client before surgery.
