If a patient is diagnosed with an ileus, which of the following signs would you expect to observe?

When a patient presents with an ileus, several clinical signs are typically observed, reflecting the condition of intestinal obstruction or impaired motility. A distended abdomen is a common finding because the accumulation of gas and fluids can cause the abdominal cavity to swell. This distension can lead to discomfort and pain for the patient.

Radiographs showing air-filled small intestine are indicative of an ileus as they reveal the presence of gas in the bowel loops that have not been able to progress properly due to the lack of peristalsis. This aspect is crucial in diagnosing an ileus, as normal bowel function would allow for gas and contents to move along the digestive tract.

Vomiting may also occur in patients with an ileus, particularly if the obstruction is significant enough to prevent the passage of contents. This can lead to a buildup of gastric contents, which may cause the patient to vomit as the body attempts to expel the material it cannot process.

Since each of these signs is consistent with a diagnosis of ileus, it is correct to conclude that all of them would be expected observations in a patient with this condition. This comprehensive understanding reinforces the need to assess all symptoms to accurately manage and treat ileus.
