,NR 328 Pediatric GI Dysfunction Comprehensive Exam 2026/2027 UPDATE – Chamberlain
1. A 6-week-old infant is brought to the clinic with a history of non-bilious projectile vomiting
after feedings. The nurse palpates an olive-shaped mass in the right upper quadrant. Which
acid-base imbalance is this infant most at risk for developing?
A. Metabolic acidosis
B. Respiratory alkalosis
C. Respiratory acidosis
D. Metabolic alkalosis
Answer: D
Rationale: Hypertrophic pyloric stenosis causes persistent vomiting of gastric contents
(hydrochloric acid), leading to a loss of hydrogen and chloride ions, resulting in metabolic
alkalosis.
2. When assessing a newborn, the nurse notes the infant has not passed meconium within
the first 48 hours of life. The infant’s abdomen is distended, and there is bile-stained emesis.
Which diagnostic test is the definitive gold standard for confirming Hirschsprung disease?
A. Rectal suction biopsy
B. Abdominal X-ray (KUB)
C. Barium enema
, D. Anorectal manometry
Answer: A
Rationale: A rectal suction biopsy is the definitive test for Hirschsprung disease because it
demonstrates the absence of ganglion cells in the bowel wall.
3. A 9-month-old infant presents with sudden, episodic abdominal pain, drawing up of the
knees to the chest, and ‘currant jelly’ stools. The nurse suspects intussusception. What is the
primary therapeutic management for this condition?
A. Hydrostatic reduction using air or saline enema
B. Administration of high-dose corticosteroids
C. Immediate surgical resection of the bowel
D. NPO status and IV fluid maintenance only
Answer: A
Rationale: Intussusception is often treated successfully with a non-surgical hydrostatic
reduction (air or saline enema), which uses pressure to ‘un-telescope’ the bowel.
4. A nurse is caring for an infant who just underwent a surgical repair of a cleft lip. Which
nursing intervention is a priority to protect the surgical site?
A. Place the infant in a prone position for drainage
B. Use a regular nipple for feedings immediately post-op
C. Apply elbow restraints (No-No’s) to prevent the infant from touching the face
