Which action should the nurse take when caring for a 6-month-old infant with intussusception?

When caring for a 6-month-old infant with intussusception, preparing the child for a barium enema is a crucial action. A barium enema is both a diagnostic and therapeutic procedure for intussusception. It allows visualization of the intestines via X-ray, helping to confirm the presence of intussusception. Additionally, the introduction of barium can sometimes resolve the condition by pushing the affected part of the intestine back into place, alleviating the blockage.

This procedure is preferred in many cases because it is less invasive compared to surgical intervention and can provide immediate therapeutic benefits. It is important for the nurse to ensure that the child is properly prepared for this procedure to ensure accuracy of the results and safety during the process.

Administering oral fluids may not be appropriate, as the infant may have an ileus or obstruction that prevents safe oral intake. Starting suctioning is typically reserved for more severe cases where there is significant gastrointestinal distress or perforation. Encouraging solid food for an infant who is experiencing gastrointestinal issues would not be advised, as their digestive system needs time to heal and any solid intake could exacerbate the problem.
