What does a gastrostomy tube allow for?

1. Administering liquids directly to the liver

2. Removing substances from the lungs

3. Giving drugs orally

4. Inserting drugs, liquids, and food into the stomach through a tube

The correct answer is: Inserting drugs, liquids, and food into the stomach through a tube

A gastrostomy tube, often referred to as a G-tube, is a medical device that is inserted through the abdominal wall directly into the stomach. Its primary function is to provide a means of delivering nutrition, fluids, and medications directly into the stomach for patients who cannot consume food or liquids by mouth due to various medical conditions. This method is particularly useful for individuals who may have swallowing difficulties, neurological disorders, or other health issues that impair their ability to ingest food normally. By using a G-tube, healthcare providers can ensure that patients receive the necessary nutrients and hydration in a way that is safe and effective, facilitating proper digestion and nutrient absorption. The other options focus on different medical processes that do not relate to the function or use of a gastrostomy tube. For example, administering liquids directly to the liver or removing substances from the lungs pertains to entirely different treatments and procedures. Giving drugs orally, while it involves medication administration, does not apply when a patient is unable to swallow or has a G-tube in place. Thus, the correct answer accurately reflects the purpose and use of a gastrostomy tube in patient care.
