, SECTION 1 — GI Disorders: Dehydration, Diarrhea & Vomiting
Q1. A 9-month-old is brought to the clinic with a 2-day history of watery diarrhea and decreased wet diapers. The nurse assesses the
infant and notes sunken fontanel, dry mucous membranes, and capillary refill of 3 seconds. The parent asks how much fluid the infant
needs. Using the standard maintenance fluid calculation for a 10-kg infant, what is the approximate daily maintenance fluid requirement?
A. 500 mL/day
B. 1000 mL/day
C. 1500 mL/day
D. 2000 mL/day
Correct Answer: B
Rationale: The Holliday-Segar method gives 100 mL/kg for the first 10 kg = 1000 mL/day. This infant also requires replacement of ongoing losses, but the
base maintenance volume is 1000 mL.
Q2. A toddler with acute gastroenteritis is being rehydrated orally. The nurse teaches the parent about oral rehydration solution (ORS).
Which statement by the parent indicates correct understanding of ORS use?
A. I will give large amounts of juice and soda to replace fluids quickly.
B. I will use only plain water without any electrolytes.
C. I will withhold all fluids until the diarrhea completely stops.
D. I will offer small, frequent amounts of an oral rehydration solution and continue breastfeeding if the child is nursing.
Correct Answer: D
Rationale: ORS replaces both fluid and electrolytes in controlled volumes. Breastfeeding should continue. Hyperosmolar fluids such as juice or soda can
worsen diarrhea.
Q3. A 6-week-old infant is admitted with projectile non-bilious vomiting after feedings, visible gastric peristalsis, and an olive-shaped
mass in the right upper quadrant. The nurse anticipates which diagnosis and primary surgical intervention?
A. Intussusception treated with air enema only
B. Hirschsprung disease treated with pull-through immediately
C. Hypertrophic pyloric stenosis treated with pyloromyotomy
D. Gastroesophageal reflux treated with fundoplication
Correct Answer: C
Rationale: Classic signs of hypertrophic pyloric stenosis include non-bilious projectile vomiting, olive mass, and visible peristalsis. Pyloromyotomy is the
definitive surgical treatment after fluid and electrolyte correction.
Q4. A 2-year-old is brought in with intermittent severe abdominal pain, currant-jelly stools, and a sausage-shaped mass in the upper
abdomen. The nurse recognizes these findings as most consistent with which condition?
A. Appendicitis
B. Intussusception
C. Pyloric stenosis
D. Celiac disease
Correct Answer: B
Rationale: Intussusception classically presents with intermittent colicky pain, currant-jelly stools, and a palpable sausage-shaped mass. Prompt diagnosis
and reduction (air/contrast enema or surgery) are required.
Q5. A newborn fails to pass meconium within the first 48 hours and has abdominal distention. A rectal biopsy is planned. The nurse
understands that Hirschsprung disease is caused by which pathologic finding?
A. Absence of ganglion cells in a segment of the bowel
B. Hypertrophy of the pyloric muscle
C. Telescoping of one portion of intestine into another
D. Inflammation of the appendix
Correct Answer: A
Rationale: Hirschsprung disease results from failure of neural crest cells to migrate, leaving a segment of bowel without ganglion cells. The aganglionic
segment remains contracted, causing functional obstruction.
Q6. A child with severe dehydration is receiving intravenous fluid resuscitation. After the initial bolus, the nurse reassesses and notes
improved mental status and capillary refill. What is the priority ongoing nursing action during continued rehydration?
A. Restrict all oral intake indefinitely
B. Discontinue all monitoring once the first bolus is complete
C. Monitor intake and output, vital signs, and electrolyte results closely while advancing to maintenance fluids as tolerated
D. Administer only hypotonic fluids regardless of laboratory values
Correct Answer: C
Rationale: After initial volume expansion, careful monitoring of I&O;, vital signs, weight, and electrolytes guides the transition to maintenance and
replacement fluids and detects over- or under-hydration.
