Which statement describes a jejunostomy (J) tube?

• A. Inserted through endoscopy into jejunum via abdominal wall
• B. Inserted through nostril
• C. Inserted through small incision into stomach
• D. Inserted into colon

Answer: (A)

A jejunostomy tube provides direct access to the jejunum through an opening in the abdominal wall, usually placed surgically or with percutaneous endoscopic guidance. This allows enteral feeding bypassing the stomach, which is important when gastric feeding is not possible or is risky. The description in question matches this setup because it specifies placement into the jejunum via the abdominal wall with endoscopic assistance. Feeding tubes inserted through the nostril are nasoenteric (to the stomach or beyond), not through a surgical opening in the abdomen. A tube inserted into the stomach via a small incision is a gastrostomy tube, not a jejunostomy. A tube placed into the colon describes a colostomy or colonic access, not jejunal access.
