Can a terminally ill patient refuse a feeding tube?

The technical term for a "feeding tube" is "artificial nutrition and hydration" in which food and water are provided by alternate means to a patient unable to eat and drink by mouth. The provision of food and water is not considered medical treatment but basic comfort care. However, the feeding of a dying patient may not be in the patient's best interest if the patient's death is imminent or if the patient is unable to assimilate the nutrition.
