Final answer:
A supine view on an abdominal x-ray can help differentiate between an ileus and obstruction based on specific findings. Ileus is a functional obstruction while obstruction refers to a mechanical blockage. An ileus would show a generalized air-fluid level throughout the abdomen, while an obstruction would present with a localized air-fluid level.
Step-by-step explanation:
When using a supine view on an abdominal x-ray, the NP can differentiate between an ileus and obstruction based on specific findings. An ileus is a functional obstruction of the intestines, while obstruction refers to a mechanical blockage. On the supine x-ray, an ileus would show a generalized air-fluid level throughout the abdomen, indicating a lack of peristalsis. On the other hand, an obstruction would present with a localized air-fluid level, indicating a specific site of blockage.
