Which of the following is NOT true about endotracheal tubes?

• A. It provides an airway in which gas anesthetics can be administered.
• B. It provides an airway in which oxygen can be administered.
• C. It can help to resuscitate an animal that has stopped breathing during surgery.
• D. It allows nutrients to enter the body.

Answer: (D)

Endotracheal tubes secure and maintain a visible airway so gases can reach the lungs and ventilation can be controlled. They’re connected to anesthesia machines to deliver inhaled anesthetics and provide oxygen, which keeps the animal breathing effectively during surgery. They also allow rescue ventilation during resuscitation if breathing stops, helping to support circulation and gas exchange until breathing can resume. Nutrients, however, are not delivered through an airway tube. Feeding requires access to the digestive tract—through the mouth and esophagus to the stomach (or via specially placed feeding tubes into the stomach or small intestine) or through other non-airway routes. An endotracheal tube in the trachea would risk delivering nutrients into the lungs, which could cause serious complications. That’s why the statement about nutrients entering the body is not true.
