What is a primary purpose of a nasogastric tube, and what are key nursing responsibilities?

• A. Administer IV fluids
• B. Provide respiratory support
• C. Decompression, gastric lavage, or feeding as ordered
• D. Measurement of blood pressure

Answer: (C)

The main idea is that a nasogastric tube is used to manage the stomach’s contents by decompressing the stomach, performing gastric lavage when needed, or delivering feeding as ordered. Decompression relieves pressure from gas or secretions and helps prevent vomiting and aspiration. Gastric lavage can be used in certain emergencies to wash out the stomach, and feeding via the tube provides nutrition when oral intake isn’t possible. Nursing responsibilities center on safety and effectiveness. First, confirm the tube’s placement and keep it secure; initial placement is typically verified with imaging, and ongoing checks (such as measuring external length and, when allowed, aspirate pH) help ensure it remains in the stomach. Keep the tube patent by flushing with water before and after use, and connect it to suction only if prescribed. Position the patient with the head of the bed raised to reduce the risk of reflux and aspiration. Monitor the drainage or residual contents, assess for signs of obstruction or complications, and perform regular mouth and nasal care to prevent irritation. If feeding is ordered, monitor tolerance, check residual volumes as indicated, and flush between meds and feeds; administer medications via the tube as allowed (crushed and dissolved in water, with appropriate flushing and avoidance of certain pill forms). Secure the tube to prevent dislodgement and protect the nares and surrounding skin. Remove the tube when it’s no longer needed or as directed. Keep thorough notes on intake and output, patient comfort, and any adverse signs so issues can be addressed promptly.
