GASTROINTESTINAL & HEPATIC CONDITIONS IN CHILDREN
Gastrointestinal and hepatic disorders represent a significant portion of childhood illnesses and require
specialized knowledge for accurate assessment, early intervention, and coordinated family-centered care.
This multiple-choice examination evaluates advanced understanding of digestive and hepatic function in
children, emphasizing both acute and chronic conditions such as gastroenteritis, congenital malformations,
inflammatory bowel disease, celiac disease, short-gut syndrome, liver failure, biliary atresia, and metabolic
liver disorders.
The assessment challenges learners to interpret clinical presentations, identify early warning signs such as
dehydration, jaundice, malabsorption, or failure to thrive, and apply appropriate nursing interventions.
Focus areas include diagnostic procedures, nutritional therapy, fluid-electrolyte balance, medication
administration, and supportive measures tailored to developmental stages.
Scenario-based questions reinforce the use of evidence-based practice, emphasizing teaching strategies for
parents, prevention of complications, and multidisciplinary collaboration. Detailed rationales accompany
each item to strengthen critical thinking, clarify clinical decisions, and enhance mastery of pediatric
gastrointestinal and hepatic nursing care.
This assessment supports competency building for professional certification, academic coursework, and
advanced pediatric clinical training.
A 3-year-old presents with profuse watery diarrhea following ingestion of contaminated water. The
most likely cause is:
A. Rotavirus infection
B. Salmonella enteritidis
C. Vibrio cholerae
D. Giardia lamblia
Correct Answer: D. Giardia lamblia
Rationale:
Giardia lamblia is a protozoan parasite that commonly causes chronic or acute watery diarrhea in children
who consume contaminated water, especially from lakes, wells, or poorly treated sources. The infection
disrupts intestinal absorption and leads to steatorrhea, weight loss, and failure to thrive if untreated.
Rotavirus typically causes acute viral gastroenteritis in infants, presenting with vomiting and fever, but
spreads via fecal–oral route, not primarily through untreated surface water. Salmonella enteritidis produces
febrile gastroenteritis with blood or mucus in stool, whereas Vibrio cholerae causes “rice-water” diarrhea
that is more profuse and severe.
Giardiasis should be suspected when diarrhea is prolonged, malodorous, and associated with abdominal
distension. Diagnosis is confirmed by stool antigen testing or microscopy. Treatment involves
metronidazole and ensuring safe water hygiene.
,A child with suspected celiac disease presents with chronic diarrhea, abdominal distention, and
poor growth. The diagnostic test of choice is:
A. Fecal occult blood test
B. Hydrogen breath test
C. Serum tissue transglutaminase IgA (tTG-IgA)
D. Stool culture
Correct Answer: C. Serum tissue transglutaminase IgA (tTG-IgA)
Rationale:
Celiac disease is an immune-mediated enteropathy triggered by gluten ingestion in genetically predisposed
individuals. The tTG-IgA test is the most sensitive and specific non-invasive screening tool. Positive
findings are often followed by confirmatory small-bowel biopsy showing villous atrophy.
The hydrogen breath test evaluates lactose intolerance, not celiac disease. Stool culture detects infectious
causes, while fecal occult blood identifies bleeding rather than malabsorption.
Timely identification and strict gluten-free diet adherence prevent growth retardation, anemia, and
osteopenia in pediatric patients.
A neonate fails to pass meconium within 48 hours, presents with abdominal distention and bilious
vomiting. The most likely diagnosis is:
A. Pyloric stenosis
B. Hirschsprung disease
C. Intussusception
D. Necrotizing enterocolitis
Correct Answer: B. Hirschsprung disease
Rationale:
Hirschsprung disease results from congenital absence of ganglion cells in the distal bowel, leading to
functional obstruction. The delayed passage of meconium, abdominal distention, and bilious vomiting are
key clinical signs.
Contrast enema reveals a transition zone between dilated proximal and narrow distal bowel. Definitive
diagnosis requires rectal biopsy demonstrating aganglionosis.
Pyloric stenosis typically presents later (2–8 weeks) with non-bilious vomiting. Intussusception presents
with intermittent colicky pain and “currant jelly” stools, while necrotizing enterocolitis is seen mainly in
preterm infants with systemic toxicity.
Early surgical intervention (pull-through procedure) is curative.
The nurse observes projectile, non-bilious vomiting in a 6-week-old infant after feeding. On
palpation, a small “olive-like” mass is felt in the right upper quadrant. The likely diagnosis is:
A. Duodenal atresia
B. Hypertrophic pyloric stenosis
,C. Gastroesophageal reflux
D. Malrotation with volvulus
Correct Answer: B. Hypertrophic pyloric stenosis
Rationale:
Hypertrophic pyloric stenosis results from hypertrophy of the pyloric muscle, causing gastric outlet
obstruction. The hallmark is projectile, non-bilious vomiting soon after feeding, with visible peristaltic
waves and a palpable “olive” mass.
Duodenal atresia typically presents with bilious vomiting and the “double-bubble” sign on X-ray. Reflux
causes mild regurgitation, not projectile vomiting. Malrotation with volvulus presents with bilious vomiting
and severe distress.
Management involves fluid/electrolyte correction and pyloromyotomy. Early recognition prevents
dehydration and metabolic alkalosis.
A 4-year-old presents with painless rectal bleeding and anemia. The most likely cause is:
A. Anal fissure
B. Meckel’s diverticulum
C. Ulcerative colitis
D. Polyposis coli
Correct Answer: B. Meckel’s diverticulum
Rationale:
Meckel’s diverticulum, a congenital remnant of the vitelline duct, often contains ectopic gastric mucosa
capable of secreting acid, leading to painless rectal bleeding. It is the most common congenital anomaly of
the gastrointestinal tract.
Anal fissure causes painful bleeding. Ulcerative colitis produces chronic, inflammatory, painful bleeding,
not isolated anemia. Polyposis coli is rare in this age group and usually presents later with multiple polyps.
Diagnosis is confirmed with a technetium-99m pertechnetate scan, and surgical resection is curative.
A 2-year-old presents with intermittent severe colicky pain, drawing knees to chest, and “currant
jelly” stools. The best initial diagnostic test is:
A. Abdominal ultrasound
B. Colonoscopy
C. Barium enema
D. CT scan
Correct Answer: A. Abdominal ultrasound
Rationale:
Ultrasound is the first-line imaging tool for intussusception, revealing the “target” or “doughnut” sign. It is
non-invasive, rapid, and avoids radiation exposure.
, Barium or air enema can be both diagnostic and therapeutic but is performed after ultrasound confirmation.
Colonoscopy is contraindicated in acute obstruction. CT scan exposes the child to unnecessary radiation.
Early diagnosis prevents ischemia and bowel necrosis. Prompt non-surgical reduction or surgical correction
is lifesaving.
A child with cystic fibrosis presents with steatorrhea, poor weight gain, and vitamin deficiency. The
most appropriate nursing intervention is:
A. Restrict fat intake
B. Encourage high-calorie, high-protein, and moderate-fat diet with pancreatic enzymes
C. Provide low-protein diet
D. Limit salt intake
Correct Answer: B. Encourage high-calorie, high-protein, and moderate-fat diet with pancreatic
enzymes
Rationale:
Cystic fibrosis causes pancreatic enzyme deficiency and malabsorption. Nutritional management aims to
compensate for energy loss by increasing caloric and protein intake. Pancreatic enzyme supplementation
before meals optimizes absorption.
Fat restriction worsens energy deficit, and low-protein diets hinder growth. Salt supplementation not
restriction is often needed due to increased sweat sodium loss.
Nutritional support is a cornerstone of cystic fibrosis management, improving survival and quality of life.
Which of the following is an early clinical sign of dehydration in an infant?
A. Sunken eyes
B. Oliguria
C. Weight loss
D. Dry mucous membranes
Correct Answer: D. Dry mucous membranes
Rationale:
Early dehydration manifests as dry mucous membranes, irritability, and mild thirst. As dehydration
progresses, sunken eyes, poor skin turgor, and oliguria appear.
Weight loss confirms severity but occurs later. Early recognition allows timely fluid replacement,
preventing hypovolemic shock.
Nursing care emphasizes accurate intake/output charting and parent education on signs of dehydration.
A 6-year-old presents with periumbilical pain that later localizes to the right lower quadrant,
accompanied by fever and vomiting. The most likely diagnosis is:
A. Acute appendicitis
B. Mesenteric adenitis
