What should the nurse inform the parents regarding the diagnosis of possible intussusception in their child?

When communicating with parents about the diagnosis of possible intussusception, it is essential to emphasize the role of imaging studies in confirming the condition. An abdominal ultrasound is a non-invasive and effective diagnostic tool that can identify the presence of a "target sign" or "doughnut sign," which are characteristic indicators of intussusception. This method is particularly useful in children as it avoids exposure to radiation and is sensitive in detecting this condition.

Parents should understand that while clinical symptoms—such as intermittent abdominal pain, vomiting, and red currant jelly stools—are critical in suspecting intussusception, confirming the diagnosis relies on imaging. Therefore, an abdominal ultrasound is a key step in the diagnosis process and provides valuable information that guides further management and treatment options for their child.
