Chapter 22: The Child with Gastrointestinal Dysfunction - Nurselytic

Correct Answer: C

Rationale: The NG tube prevents abdominal distention by suctioning gastrointestinal secretions. It doesn?t prevent infection, electrolyte monitoring is secondary, and while output records are important, the primary purpose is distention prevention.

Correct Answer: C

Rationale: Thickening feedings and enlarging the nipple hole reduces emesis volume and frequency by increasing caloric density and easing feeding. Surgery is for severe cases, prone positioning risks SIDS, and smaller, frequent feedings are better than larger volumes.

Correct Answer: A

Rationale: Notifying the practitioner is critical, as replacing an NG tube after upper GI surgery risks injury to the surgical site and requires surgical team evaluation. Inserting or replacing the tube independently or assuming it?s no longer needed bypasses necessary medical oversight.

Correct Answer: B

Rationale: Stress management can reduce irritable bowel syndrome symptoms by addressing its psychologic and autonomic components. A high-fiber diet is beneficial, milk products may worsen symptoms in lactose intolerance, and proton pump inhibitors are ineffective for IBS.

Correct Answer: D

Rationale: Colicky, periumbilical pain that becomes constant and may shift to the right lower quadrant is the hallmark of acute appendicitis. Rebound tenderness is unreliable and painful, bleeding is not typical, and pain relieved by eating is not associated with appendicitis.
