A 9-year-old child presents to the emergency department with acute appendicitis and is scheduled for surgery. The child is scheduled for an appendectomy in 2 hours. Which nursing intervention should be the priority at this time?
1Apply a heating pad to the abdomen to relieve pain
2Maintain the child on NPO status✓ 정답
3Administer a Fleet enema to cleanse the bowel
4Encourage ambulation to prevent complications
해설
Maintaining NPO status is essential pre-operatively to prevent aspiration during anesthesia. Other options such as heat, enema, or ambulation are contraindicated as they may exacerbate inflammation or increase perforation risk.
Understanding the Clinical Priority
For a child with acute appendicitis awaiting surgery, the immediate nursing priority is to prevent aspiration during anesthesia. The inflamed appendix poses a risk of perforation, which can slow gastric emptying. Maintaining NPO (nothing by mouth) status is a critical safety intervention to ensure the stomach is empty before the induction of general anesthesia.
Why NPO Status is the Priority
The primary goal of preoperative fasting is to reduce the volume and acidity of gastric contents, thereby minimizing the risk of pulmonary aspiration of regurgitated stomach contents during anesthesia. This is a life-threatening complication that can lead to pneumonitis or acute respiratory distress syndrome. The provided research underscores that rational preoperative fasting is essential to "reduce the risk of regurgitation and aspiration" and "enhance anesthesia safety" [1]. For a child scheduled for surgery in 2 hours, strict adherence to NPO guidelines is the most time-sensitive safety measure.
Analysis of Incorrect Options
- Option 1: Apply a heating pad to the abdomen. This is contraindicated in suspected appendicitis. Heat application can increase blood flow to the area, potentially accelerating the inflammatory process and increasing the risk of appendix rupture, leading to peritonitis.
- Option 3: Administer a Fleet enema. This is dangerous for a patient with acute appendicitis. An enema increases intestinal peristalsis and intraluminal pressure, which can directly precipitate perforation of the inflamed appendix.
- Option 4: Encourage ambulation. While early ambulation is beneficial post-operatively to prevent complications like atelectasis and venous thromboembolism, it is not a preoperative priority. Preoperatively, the child's pain and the risk of perforation necessitate rest and comfort measures, not activity.
Connecting Research to Practice
The study on pediatric preoperative fasting highlights a gap between guideline recommendations and real-world practice, noting the adverse effects of prolonged fasting [1]. Your role is to balance safety with patient comfort. While the NPO order is absolute, you must also advocate for the shortest safe fasting period. The research emphasizes mitigating "the adverse effects of prolonged fasting," which in children can include dehydration, hypoglycemia, and irritability [1]. This means you should verify the exact time the child last had clear liquids versus solids, as current guidelines often allow clear fluids up to 1-2 hours before surgery. Your precise documentation and communication with the anesthesia team are vital to prevent unnecessarily long fasting times while maintaining the safety mandate of an empty stomach.

Situation
A 9-year-old child with acute appendicitis is scheduled for an appendectomy in 2 hours. The immediate nursing priority is to maintain NPO status to prevent aspiration during anesthesia induction.
Background
Acute appendicitis can delay gastric emptying, increasing the risk of regurgitation and pulmonary aspiration under general anesthesia. Aspiration of gastric contents is a life-threatening event that can lead to chemical pneumonitis or acute respiratory distress syndrome (ARDS). Standard preoperative fasting guidelines aim to reduce gastric volume and acidity.
Assessment
Verify the time of the last oral intake, including solids, clear liquids, and breast milk or formula, and document it clearly.
Confirm the scheduled surgery time and communicate with the anesthesia team regarding NPO status.
Assess the child's pain level, vital signs, and signs of appendix perforation (e.g., sudden relief of pain followed by diffuse abdominal pain, fever, tachycardia).
Ensure the child's identification band and surgical consent are correct and complete.
Recommendations
Strictly enforce NPO status. Do not allow any oral intake, including water, ice chips, or chewing gum.
Do not apply heat to the abdomen; this can increase inflammation and risk of perforation.
Do not administer enemas or laxatives, as increased peristalsis may cause perforation.
Maintain bed rest in a position of comfort; ambulation is not a priority and may exacerbate pain.
Administer prescribed intravenous fluids and preoperative antibiotics as ordered to maintain hydration and prevent infection.
Provide developmentally appropriate explanations to the child and family about why the child cannot eat or drink, using simple terms to reduce anxiety.
Use non-pharmacological pain relief methods such as distraction or positioning, and administer analgesics only as prescribed and after surgical evaluation.
Key Safety Alert
Pulmonary aspiration of gastric contents is a critical, preventable complication. Adherence to NPO guidelines is a non-negotiable safety standard in preoperative care for all patients, especially children with acute abdominal conditions.
NPO (Nil Per Os) — Nothing by mouth; a preoperative fasting status essential to reduce gastric volume and acidity, minimizing the risk of pulmonary aspiration during anesthesia.
Pulmonary Aspiration — Inhalation of gastric contents into the lungs, a life-threatening complication of general anesthesia that can cause pneumonitis or acute respiratory distress syndrome.
Appendicitis — Inflammation of the appendix, which poses a risk of perforation and peritonitis, often slowing gastric emptying and increasing aspiration risk.
Peritonitis — Inflammation of the peritoneum, a serious complication resulting from a ruptured appendix that can lead to systemic infection.
Preoperative Fasting — A safety protocol requiring patients to abstain from food and fluids for a specified period before surgery to enhance anesthesia safety.
