A 4-month-old infant is brought to the hospital for recurrent vomiting. The child is diagnosed with gastroenteritis. To decrease vomiting, the child should be NPO for approximately how long?

3-6 hours


•To decrease vomiting, withholding food and fluid for a time (NPO), depending on the age of the child. On the average, 3-6 hr are usually sufficient. If there is nothing in the stomach, vomiting cannot occur.

•More than 6 hours is too long to withhold any food or milk. This would compound the problem by adding to the dehydration and malnutrition.
