The primary function of a gastrostomy tube is to administer food directly into the stomach through a tube. This is especially important for patients who are unable to eat by mouth due to various medical conditions, such as neurological disorders, surgery, or other health issues that impair swallowing. The gastrostomy tube allows for nutritional support, ensuring that the patient receives necessary calories and nutrients. This method can also help prevent aspiration, which is when food or fluids enter the airway, as it bypasses the oral and pharyngeal phases of swallowing.

Delivering drugs directly to the lungs is associated with respiratory treatments, which does not involve a gastrostomy tube. Removing substances from the intestine pertains to procedures like enemas or surgical interventions rather than the function of a feeding tube. Monitoring blood pressure levels is a completely different procedure that involves the cardiovascular system, unrelated to feeding or nutritional support. Thus, the correct choice highlights the essential role of a gastrostomy tube in providing direct nutritional intake to those in need.
