What is the purpose of an enteral or nasogastric tube in postoperative care?

• A. Gastric decompression, prevention of aspiration, and monitoring of GI function
• B. Deliver oxygen
• C. Restrict GI function
• D. Provide a source of nutritional support only

Answer: (A)

After surgery, the stomach often contains secretions and gas and the bowel’s movements are slowed. An enteral or nasogastric tube helps by decompressing the stomach, which reduces distention and nausea and lowers the risk of aspiration if regurgitation occurs. It also provides a way to monitor the GI tract’s function through the drainage that comes out—the amount, color, and consistency can give clues about how well the stomach and intestines are healing and returning to normal.

This option is best because it covers the primary postoperative roles: keeping the stomach empty to prevent complications, protecting the airway, and giving direct information about GI function. In contrast, delivering oxygen is not a function of an NG tube, restricting GI function is not the goal of decompression, and providing nutrition only is incomplete since the tube’s main postoperative purposes are decompression and airway protection, with monitoring as an added benefit.
