A 9-month-old infant is admitted to the pediatric unit with suspected intussusception. The infant has been experiencing intermittent abdominal pain, vomiting, and has passed one stool containing blood and mucus. What is the priority nursing intervention for this infant?

Intussusception is a pediatric emergency requiring immediate diagnosis and intervention to prevent bowel necrosis. Priority nursing intervention is preparing for diagnostic imaging and therapeutic procedures, as non-surgical reduction (e.g., barium enema) is time-sensitive. Other options address supportive care but delay critical treatment.

Understanding Intussusception
Intussusception is a serious condition where a proximal segment of the intestine telescopes into a distal segment, leading to bowel obstruction, venous compression, edema, and eventually arterial insufficiency. In a 9-month-old infant presenting with the classic triad of intermittent abdominal pain, vomiting, and the passage of "currant jelly" stool (blood and mucus), the condition is a medical emergency. The primary concern is that prolonged intussusception leads to bowel ischemia, necrosis, and perforation.

Why Option 2 is the Priority
The priority nursing intervention is to prepare the infant for immediate diagnostic imaging and possible therapeutic intervention. The rationale is grounded in the time-sensitive nature of the condition. A study on the impact of a delay between diagnostic ultrasound and fluoroscopic reduction for ileocolic intussusception highlights that this is considered a radiologic urgency requiring 24-hour availability of radiologists and technologists . While the study assessed outcomes related to a 6–12 hour delay, the underlying principle is that timely reduction is critical to maximize the chance of a successful non-surgical reduction and to minimize the risk of bowel ischemia. The nurse's role is to facilitate this process urgently by ensuring NPO (nothing by mouth) status, establishing IV access, and coordinating with the radiology and surgical teams.

Analysis of Incorrect Options
- Option 1 (Administer prescribed analgesics): While pain management is an important nursing consideration, it is not the priority. Administering an analgesic before a definitive diagnosis or intervention could mask a critical change in the infant's pain pattern, such as a sudden cessation of pain that could indicate perforation. The priority is to address the underlying cause of the pain, which is the obstruction.
- Option 3 (Encourage oral fluid intake): This intervention is contraindicated. The infant has a bowel obstruction and is vomiting. Oral intake would worsen vomiting, increase the risk of aspiration, and is not an effective way to manage dehydration in this scenario. The infant should be kept NPO in preparation for a procedure or potential surgery.
- Option 4 (Apply warm compresses to the abdomen): This provides minimal comfort and does nothing to address the life-threatening bowel obstruction. It delays definitive care and could potentially mask symptoms without treating the underlying pathology.

The urgency of the situation is paramount. The clinical presentation of a "currant jelly" stool is a late sign indicating bowel ischemia and mucosal sloughing. Immediate reduction, typically via air or contrast enema under fluoroscopic guidance, is the definitive treatment to salvage the bowel . The nurse's priority is to prepare the patient for this time-critical intervention.
