Final answer:
A specific patient position for increased peristaltic motion is not given, but upright positions where gravity can assist, along with the secretion of motilin, enhance peristalsis for stomach emptying.
Step-by-step explanation:
The patient position that results in an increased peristaltic motion for the emptying of the stomach is not explicitly stated, but peristalsis is generally aided by the body's natural anatomy and gravity. When a person is upright, gravity can assist the downward motion of food, although peristalsis is capable of moving food through the digestive system in any position, even when upside-down. This is due to the fact that peristaltic motion is an active process involving muscle contractions along the digestive tract.
Additionally, the secretion of the hormone motilin accelerates gastric emptying and stimulates intestinal peristalsis. It is implied that certain patient positions may aid this process, possibly by the manner in which they facilitate the work of the muscles and hormones involved. A position that does not work against the natural direction of peristalsis and allows for the easy passage of stomach contents into the small intestine might be preferable for enhancing peristaltic motion, although this is not explicitly detailed in the example reference material.
