Final answer:
For a 35-year-old male with small bowel obstruction symptoms, the nurse should prioritize nasogastric tube insertion to relieve symptoms and prevent complications.
Step-by-step explanation:
In collaboration with the primary care provider, the nurse should prioritize the insertion of a nasogastric tube for a 35-year-old male patient presenting with symptoms of a small bowel obstruction. This intervention is critical to decompress the stomach and upper intestine, which helps relieve the patient's symptoms and prevent further complications. The nasogastric tube can remove gastric contents, alleviate pressure, and minimize the risk of aspiration.
