Explanation

Hirschsprung disease is characterized by an absence of ganglion cells in the colon, leading to functional obstruction, accumulation of stool and gas, and significant abdominal distension.
A contrast enema introduces fluid under pressure, which poses a risk of perforating the distended and potentially fragile bowel wall.
Measuring the abdominal girth before the procedure establishes a critical baseline measurement.
This baseline is essential for post-procedure monitoring. A rapid increase in abdominal girth after the enema is a key sign of bowel perforation, a medical emergency.

Option B: This is a post-procedure assessment. While necessary, it is not a preoperative action. Without a pre-procedure baseline, the measurement is less valuable for detecting acute changes.
Option C: Avoiding assessment is contrary to all principles of safe nursing care. A thorough preoperative assessment is mandatory to identify risks and establish baselines.
Option D: This is an incomplete assessment. To detect any change in bowel motility post-procedure, a baseline assessment of bowel sounds must be performed before the procedure.

Clinical Relevance

Nursing practice connection: Use the key finding related to Preoperative nursing assessment for a child with Hirschsprung disease undergoing a contrast enema to guide bedside assessment, documentation, and the next nursing action.
A nurse's primary role in this scenario is patient safety, which involves meticulous assessment to prevent and detect complications early.
Bowel perforation is a life-threatening complication of contrast enemas in patients with Hirschsprung disease. Prompt recognition of signs like increasing abdominal girth and notifying the physician is critical.
What if? If the child's post-procedure abdominal girth increases by 2 cm, they develop a fever, and their abdomen becomes rigid and tender, the nurse must suspect bowel perforation. The immediate actions are to stop all oral intake, notify the surgical team immediately, monitor vital signs for shock, and prepare the child for emergency surgery.

How to Approach the Question

First, identify the core components of the question: the patient's diagnosis (Hirschsprung disease), the planned procedure (contrast enema), and the timing of the action (preoperative).
Recall the key pathophysiology of Hirschsprung disease: aganglionic megacolon leads to severe constipation and abdominal distension.
Consider the risks associated with the procedure. A contrast enema involves pressure, which can perforate a distended, weakened bowel.
Evaluate each option based on whether it is a 'preoperative' assessment that directly addresses the primary risk (perforation, indicated by distension).
Eliminate options that describe post-procedure actions (B, D) or are unsafe (C).
Conclude that establishing a baseline for the most relevant sign of a major complication (abdominal girth for distension/perforation) is the most appropriate preoperative action.
