Which statement describes a gastrostomy (G) tube?

• A. Inserted through a small incision in abdomen into stomach
• B. Inserted through nostril
• C. Endoscopically into jejunum
• D. Into mouth

Answer: (A)

Gastrostomy tubes provide direct access to the stomach through the abdominal wall, usually placed through a small incision that creates a tract into the stomach (often percutaneous, sometimes with endoscopic assistance). This setup is used for long-term enteral feeding without passing through the mouth.

That’s why the description of being inserted through the abdomen into the stomach best fits a gastrostomy tube. In contrast, a tube inserted through the nostril is a nasogastric tube, a tube placed endoscopically into the jejunum describes a jejunostomy, and a tube placed into the mouth is an orogastric route.
