*QUESTION 1:*
A 4-year-old child is brought to the ED with a fever of 102°F, stridor, and drooling. The child is sitting
upright and refusing to lie down. What is the priority intervention?
A) Obtain a lateral neck X-ray
B) Prepare for immediate intubation in the operating room
C) Administer nebulized epinephrine
D) Perform a throat culture
> 🎯 *CORRECT ANSWER:* B) Prepare for immediate intubation in the operating room
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Stridor, drooling, and tripod positioning suggest epiglottitis, which can cause
sudden airway obstruction.
> * *Why Distractors Fail:* Nebulized epinephrine is for croup; X-rays and cultures delay definitive
airway management.
> * *Core Takeaway:* Epiglottitis is a medical emergency requiring controlled airway intervention.

*QUESTION 2:*
A 2-year-old child ingested an unknown amount of a liquid medication found in a bottle. The child is
lethargic with pinpoint pupils and a respiratory rate of 8 breaths/min. What is the most appropriate
initial treatment?
A) Activated charcoal
,B) Naloxone
C) Flumazenil
D) Gastric lavage
> 🎯 *CORRECT ANSWER:* B) Naloxone
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Pinpoint pupils and respiratory depression suggest opioid toxicity.
> * *Why Distractors Fail:* Charcoal is not first-line for a lethargic child; flumazenil is for
benzodiazepines.
> * *Core Takeaway:* Naloxone reverses opioid-induced respiratory depression.

*QUESTION 3:*
A 6-year-old child is hit by a car while riding a bicycle. The child is alert but complaining of severe
abdominal pain. The nurse notes seat belt sign across the lower abdomen. What is the most concerning
potential injury?
A) Splenic rupture
B) Liver laceration
C) Bowel perforation
D) Pelvic fracture
> 🎯 *CORRECT ANSWER:* C) Bowel perforation
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Seat belt sign is associated with intra-abdominal injuries, particularly bowel and
mesenteric injuries.
> * *Why Distractors Fail:* Splenic and liver injuries are also possible but bowel perforation is classic.
> * *Core Takeaway:* Seat belt sign warrants a high suspicion for bowel injury.

,*QUESTION 4:*
A 3-year-old child has a witnessed seizure that lasted 8 minutes. The child is now postictal but breathing
spontaneously. What is the next priority?
A) Administer a loading dose of phenytoin
B) Obtain a CT scan of the head
C) Assess the child's temperature and blood glucose
D) Prepare for endotracheal intubation
> 🎯 *CORRECT ANSWER:* C) Assess the child's temperature and blood glucose
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Fever and hypoglycemia are common causes of seizures in children.
> * *Why Distractors Fail:* Antiepileptics are for status epilepticus; CT is not emergent postictal.
> * *Core Takeaway:* Identify and treat reversible causes of seizures.

*QUESTION 5:*
A 10-year-old child presents with a sudden onset of severe, tearing chest pain radiating to the back. The
child is hypertensive and has a blood pressure differential between arms. What is the most likely
diagnosis?
A) Myocardial infarction
B) Aortic dissection
C) Pulmonary embolism
D) Pneumothorax
> 🎯 *CORRECT ANSWER:* B) Aortic dissection
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* Tearing chest pain radiating to the back with BP differential is classic for aortic
dissection.
, > * *Why Distractors Fail:* MI pain is pressure-like; PE has respiratory symptoms; pneumothorax has
sudden dyspnea.
> * *Core Takeaway:* Aortic dissection is a surgical emergency with classic pain pattern.

*QUESTION 6:*
A 5-year-old child has a fever and a non-blanching rash on the trunk and extremities. The child is
irritable and has nuchal rigidity. What is the priority action?
A) Administer empiric antibiotics
B) Obtain a CT scan of the head
C) Place the child in respiratory isolation
D) Perform a lumbar puncture
> 🎯 *CORRECT ANSWER:* A) Administer empiric antibiotics
> 💡 *CLINICAL RATIONALE:*
> * *Why It's Right:* The presentation suggests meningococcemia or meningitis; antibiotics should not
be delayed.
> * *Why Distractors Fail:* LP is important but should not delay antibiotics.
> * *Core Takeaway:* In suspected bacterial meningitis, antibiotics are given immediately.

*QUESTION 7:*
