and prepare for success on your exam!
Question 1
A 9-year-old girl has a history of frequent vomiting and her mother has frequent
migraine headaches. The child has recently begun having more frequent and
prolonged episodes accompanied by headaches. An exam reveals abnormal eye
movement and mild ataxia. What is the correct action?
A. Begin using anti-migraine meds to prevent HA
B. Prescribe ondansetron and lorazepam to help manage symptoms
C. Reassure the parent that this is expected with cyclic vomiting syndrome
D. Refer to a pediatric gastroenterologist for further workup
Correct Answer: D
Rationale: Refer to a pediatric gastroenterologist for further workup is the
correct action. The child has abnormal eye movement and mild ataxia with
vomiting/headaches, suggesting possible central nervous system pathology (e.g.,
brain tumor, metabolic disorder) rather than simple cyclic vomiting syndrome or
migraines. This requires neurological/gastroenterological evaluation to rule out
serious conditions. Anti-migraine meds without diagnosis is
inappropriate. Ondansetron/lorazepam treats symptoms but doesn't address
underlying cause. Reassurance is dangerous with neurologic signs. Pediatric NPs
must recognize neurologic signs with vomiting require workup.
Question 2
The parent of a 3-month-old reports that the infant arches and gags while feeding
and spits up undigested formula frequently. The infant's weight gain has dropped to
,the 5th percentile from the 12th. What is the best course of treatment for this
infant?
A. Begin a trial of extensively hydrolyzed protein formula for 2-4 weeks
B. Institute an empiric trial of acid suppression with a PPI
C. Perform esophageal pH monitoring to determine the degree of reflux
D. Reassure the parent that these symptoms will likely resolve by 12-24 months
Correct Answer: A
Rationale: Begin a trial of extensively hydrolyzed protein formula for 2-4
weeks is the best treatment. The infant has arched/gagged while feeding, spitting
up undigested formula, and poor weight gain (5th percentile),
suggesting Cow's Milk Protein Allergy (CMPA) rather than simple GERD.
Hydrolyzed formula eliminates cow's milk protein. PPI is for GERD but doesn't
address allergy. pH monitoring is invasive and not first-line. Reassurance is
inappropriate with weight gain failure. Pediatric NPs must recognize CMPA signs
and treat with hydrolyzed formula.
Question 3
A school-age child has a 3-month history of dull, aching epigastric pain that
worsens with eating and awakens from sleep. A CBC shows a Hgb of 8 mg/dL.
What is the next step in management?
A. Administration of H2RA or PPI meds
B. Empiric therapy for H. pylori
C. Ordering an upper GI series
D. Referral for EGD (esophagogastroduodenoscopy)
Correct Answer: D
Rationale: Referral for EGD (esophagogastroduodenoscopy) is the next step.
The child has epigastric pain worsening with eating, awakening from sleep,
and anemia (Hgb 8 mg/dL), suggesting H. pylori gastritis or peptic ulcer
disease. EGD allows direct visualization + biopsy for H. pylori and assessment
of ulceration. H2RA/PPI treats symptoms but doesn't diagnose. Empiric H. pylori
therapy without diagnosis is inappropriate. Upper GI series is less diagnostic
than EGD. Pediatric NPs must recognize GI bleeding signs and refer for EGD.
,Question 4
A 2-month-old infant cries up to 4 hours each day and, according to the parents, is
inconsolable during crying episodes with fists and legs noted to be tense and stiff.
The infant is breastfeeding frequently but is often fussy during feedings. The PE is
normal and the infant is gaining weight normally. What will the primary care
pediatric NP recommend?
A. A complete work-up, including lab and radiologic tests
B. Eliminating certain foods from the mother's diet
C. Empiric tx with PPI
D. Stopping breastfeeding & beginning a hydrolyzed formula
Correct Answer: B
Rationale: Eliminating certain foods from the mother's diet is the
recommendation. The infant has colic symptoms (inconsolable crying 4
hours/day, tense/stiff) with normal PE and weight gain, suggesting maternal
dietary sensitivity (e.g., cow's milk, caffeine, spicy foods) rather than CMPA or
GERD. Maternal diet modification is first-line for breastfeeding infants with
colic. Complete work-up is unnecessary with normal PE and weight gain. PPI is
for GERD but not indicated. Stopping breastfeeding is inappropriate;
breastfeeding should continue with diet modification. Pediatric NPs must counsel
on maternal diet for colic.
Question 5
A child is in the clinic after swallowing a metal bead. A radiograph of the GI tract
shows a 6 mm cylindrical object in the child's stomach. The child is able to
swallow without difficulty and is not experiencing pain. What is the correct course
of treatment?
A. Administer ipecac to induce vomiting
B. Have the parents watch for the object in the child's stool
C. Insert a nasogastric tube to flush out the object
D. Refer the child for endoscopic removal of the object
Correct Answer: B
Rationale: Have the parents watch for the object in the child's stool is the
correct treatment. The 6 mm cylindrical metal bead in the stomach with no
, swallowing difficulty or pain is a small foreign body that will likely pass
spontaneously. Most small objects (<2.5 cm) pass through GI tract without
intervention. Ipecac is dangerous (aspiration risk). Nasogastric tube is
unnecessary. Endoscopic removal is for objects causing obstruction, in
esophagus, or >2.5 cm. Pediatric NPs must recognize small gastric objects pass
spontaneously.
Question 6
A 10-year-old child has had abdominal pain for 2 days, which began in the
periumbilical area and then localized to the RLQ. The child vomited once today
and then experienced relief from pain followed by an increased fever. What is the
likely diagnosis?
A. Appendicitis with perforation
B. Gastroenteritis
C. Pelvic inflammatory disease (PID)
D. UTI
Correct Answer: A
Rationale: Appendicitis with perforation is the likely diagnosis. The child
has periumbilical pain localizing to RLQ (classic appendicitis progression),
vomiting, pain relief followed by increased fever, suggesting perforation (pain
relief from nerve destruction, fever from infection). Gastroenteritis has diffuse
pain, not RLQ localization. PID is in adolescent females, not 10-year-old. UTI has
urinary symptoms, not RLQ pain. Pediatric NPs must recognize appendicitis with
perforation signs urgently.
Question 7
An 18-month-old child has a 1-day history of intermittent, cramping abdominal
pain with non-bilious vomiting. The child is observed to scream and draw up his
legs during pain episodes and becomes lethargic in between. The primary care
pediatric NP notes a small amount of bloody, mucous stool in the diaper. What is
the most likely diagnosis?
A. Appendicitis
B. Gastroenteritis
