  1. A 2-year-old is brought in by EMS after being found face-down in a backyard pool. Resuscitation is in progress. Which temperature management consideration is important in pediatric submersion victims?

    Answer: Cold water submersion may be protective; do not declare death until normothermic

    Cold water submersion can provide neuroprotection; the principle 'not dead until warm and dead' applies, and resuscitation should continue until the patient is rewarmed to near-normal temperature.

  2. A 10 kg toddler requires dopamine at 10 mcg/kg/min. Using a standard concentration of 400 mcg/mL, what is the infusion rate in mL/hr?

    Answer: 15 mL/hr

    Rate (mL/hr) = (10 mcg/kg/min × 10 kg × 60 min) ÷ 400 mcg/mL = 6000 ÷ 400 = 15 mL/hr.

  3. What is the value of continuing education in gastrointestinal emergencies for CPEN professionals?

    Answer: It keeps professionals current with evolving standards and practices

    Continuing education ensures professionals stay current with the latest developments, standards, and best practices in their field.

  4. A symptomatic child with complete heart block and a heart rate of 35 bpm should initially be treated with:

    Answer: IV atropine 0.02 mg/kg

    Atropine is the first pharmacologic intervention for symptomatic bradycardia with a perfusing rhythm before pacing.

  5. A 4-year-old who swallowed a coin has it confirmed by X-ray to be in the stomach. The child is asymptomatic. What is the recommended management?

    Answer: Observation and follow serial X-rays, as most coins pass spontaneously

    Coins in the stomach of asymptomatic children will pass spontaneously in most cases and require only observation with follow-up imaging if not passed within 4 weeks.

  6. A 15-year-old presents with thunderclap headache — worst of life, sudden onset. After a negative CT, the NEXT step is:

    Answer: Lumbar puncture to detect xanthochromia

    CT misses ~2% of subarachnoid hemorrhages; LP detecting xanthochromia or blood in CSF is essential when CT is negative after thunderclap headache.

  7. A 2-year-old with sepsis has a serum glucose of 38 mg/dL. Which dextrose concentration and dose is MOST appropriate for IV correction?

    Answer: D10W 5 mL/kg IV

    D10W at 5 mL/kg (providing 0.5 g/kg glucose) is the standard pediatric hypoglycemia correction dose; higher concentrations risk vascular injury and osmotic shifts.

  8. Which statement by a parent MOST suggests that a child's conversion disorder symptoms are being reinforced?

    Answer: 'I carry her everywhere because she can't walk and I don't want her to fall.'

    Carrying a child who has functional neurological symptoms reinforces illness behavior and secondary gain, which perpetuates conversion disorder.

  9. A caregiver reports that her 4-year-old has been having nightmares, refusing to sleep alone, and is very clingy since a recent car accident. The most appropriate nursing response is:

    Answer: Refer the family for trauma-focused cognitive behavioral therapy evaluation

    Persistent post-traumatic symptoms in young children warrant referral for trauma-focused therapy; early intervention improves outcomes.

  10. Which assessment finding best differentiates peritonitis from a non-surgical cause of abdominal pain in a pediatric patient?

    Answer: Abdominal guarding and rebound tenderness

    Involuntary guarding and rebound tenderness indicate peritoneal irritation and are the most specific signs pointing to a surgical intra-abdominal emergency.

  11. After being stung by a bee, a boy experiences acute facial edema, dyspnea, and hypotension, all of which indicate anaphylaxis. The most crucial intervention is:

    Answer: epinephrine

    The symptoms of acute facial edema, dyspnea, and hypotension after a bee sting are classic signs of anaphylaxis, a severe, life-threatening allergic reaction. Epinephrine is the first-line and most crucial intervention for anaphylaxis because it rapidly reverses bronchospasm, vasoconstriction, and hypotension, directly addressing the life-threatening aspects of the reaction. While oxygen and diphenhydramine are supportive, epinephrine is the immediate life-saving medication.

  12. A teenager ingests a large amount of acetaminophen 8 hours ago. Which lab value is the priority assessment?

    Answer: Serum acetaminophen level and liver function tests

    Serum acetaminophen level plotted on the Rumack-Matthew nomogram and LFTs are essential to determine toxicity risk and need for NAC treatment.

  13. A 10-year-old presents after falling on an outstretched hand. X-ray shows a fracture through the distal radial physis with the epiphysis displaced. Which Salter-Harris classification is this?

    Answer: Type II

    Salter-Harris Type II involves a fracture through the physis that extends into the metaphysis, making it the most common type.

  14. Beck's triad (hypotension, muffled heart sounds, distended neck veins) in a trauma patient suggests:

    Answer: Cardiac tamponade

    Beck's triad is the hallmark of cardiac tamponade, caused by fluid accumulation in the pericardial sac compressing the heart.

  15. A nurse is about to give IV vancomycin rapidly and the child develops flushing, erythema, and hypotension. What is the most likely cause?

    Answer: Red Man Syndrome from rapid infusion

    Red Man Syndrome is a rate-dependent reaction caused by mast cell degranulation from rapid vancomycin infusion, not a true allergy.

  16. Racemic epinephrine administered to a child with croup requires a minimum observation period of how long after treatment?

    Answer: 2 hours

    Children must be observed for a minimum of 2 hours after racemic epinephrine due to the risk of rebound airway edema as the medication wears off.

  17. A 15-year-old reveals to the nurse that she has been self-harming but denies suicidal intent. Under mandatory reporting guidelines, what is the nurse's obligation?

    Answer: Notify the provider and initiate a psychiatric safety evaluation

    Non-suicidal self-injury requires immediate provider notification and psychiatric evaluation to assess safety; confidentiality has limits when patient safety is at risk.

  18. A 7-year-old with celiac disease presents with severe abdominal pain, distension, and obstipation after being exposed to gluten. Which complication specific to celiac disease is most concerning?

    Answer: Celiac crisis with refractory diarrhea and electrolyte imbalance

    Celiac crisis is a rare but life-threatening complication triggered by gluten exposure, characterized by severe diarrhea, dehydration, metabolic disturbances, and malnutrition.

  19. Hypertonic saline (3% NaCl) is ordered for a pediatric patient with severe TBI. The GOAL serum sodium target is:

    Answer: 150–160 mEq/L

    For ICP management with hypertonic saline, the goal serum sodium is typically 150–160 mEq/L to create an osmotic gradient that reduces cerebral edema.

  20. An infant presents with bilious vomiting and abdominal distension within the first 24 hours of life. Which condition is most concerning?

    Answer: Malrotation with midgut volvulus

    Bilious vomiting in a neonate is a surgical emergency until proven otherwise, with malrotation and midgut volvulus being the most immediately life-threatening cause.
