Pediatric Nurse Exam Pediatric Nurse Common Pediatric Emergencies 4 — Questions and Answers
Question 1: A 4-month-old is brought in unresponsive with bulging fontanelle, high-pitched cry, and petechial rash. Temperature is 39.8°C. What condition is the nurse most concerned about?
- Viral meningitis
- Bacterial meningitis with possible sepsis (Correct answer)
- Roseola infantum
- Benign febrile seizure
Correct answer: Bacterial meningitis with possible sepsis
Bulging fontanelle, high-pitched cry, and petechiae in a febrile infant are classic signs of bacterial meningitis with meningococcal sepsis, requiring immediate IV antibiotics.
Question 2: A 16-year-old presents after a motor vehicle accident with absent breath sounds on the left, tracheal deviation to the right, and hypotension. What emergency condition does the nurse suspect?
- Hemothorax
- Tension pneumothorax (Correct answer)
- Cardiac tamponade
- Flail chest
Correct answer: Tension pneumothorax
Tension pneumothorax causes absent breath sounds, tracheal deviation away from the affected side, and obstructive shock requiring immediate needle decompression.
Question 3: An 8-year-old with asthma arrives in severe respiratory distress. A silent chest is auscultated. What does a silent chest indicate in this context?
- The child has improved and air is moving freely
- Complete airway obstruction with minimal to no air movement (Correct answer)
- The stethoscope is placed incorrectly
- Mild asthma with well-controlled bronchospasm
Correct answer: Complete airway obstruction with minimal to no air movement
A silent chest in a child with status asthmaticus indicates critical airflow obstruction, meaning very little air is moving — an ominous pre-arrest sign.
Question 4: A 2-year-old presents with sudden colicky abdominal pain, currant jelly stools, and a sausage-shaped abdominal mass. What is the priority intervention?
- Immediate surgical laparotomy
- Abdominal X-ray and discharge with follow-up
- Emergent air or contrast enema for reduction (Correct answer)
- NPO and IV fluids with watchful waiting
Correct answer: Emergent air or contrast enema for reduction
Intussusception is first treated with air or hydrostatic contrast enema under fluoroscopy, which successfully reduces the intussusception in 80–90% of cases without surgery.
Question 5: A 10-month-old is brought in with decreased level of consciousness, retinal hemorrhages, and a bulging fontanelle. Radiographs reveal multiple subdural hematomas in different stages. The history is inconsistent. What is the most likely diagnosis?
- Accidental head trauma
- Abusive head trauma (shaken baby syndrome) (Correct answer)
- Glutaric aciduria type I
- Normal variant in infants
Correct answer: Abusive head trauma (shaken baby syndrome)
The triad of subdural hematomas, retinal hemorrhages, and encephalopathy with an inconsistent history is the hallmark presentation of abusive head trauma.
Question 6: A 5-year-old is in respiratory arrest following a submersion injury. Rescuers have been performing CPR for 10 minutes. Water temperature was 4°C. What resuscitation principle is most applicable?
- Cease resuscitation because prognosis is uniformly poor after 10 minutes
- Continue aggressive resuscitation because hypothermic drowning can have favorable outcomes (Correct answer)
- Administer epinephrine only if the water was fresh, not salt
- Defibrillate immediately regardless of rhythm
Correct answer: Continue aggressive resuscitation because hypothermic drowning can have favorable outcomes
Cold-water submersion can provide cerebral protection through hypothermia; the principle 'not dead until warm and dead' guides prolonged resuscitation efforts.
Question 7: A 7-year-old presents with a bee sting allergy and begins using their epinephrine auto-injector. The nurse notes the device was accidentally injected into the thumb instead of the thigh. What complication is most concerning?
- Systemic epinephrine toxicity
- Finger ischemia from vasoconstriction (Correct answer)
- Infection at the injection site
- Subcutaneous fat necrosis
Correct answer: Finger ischemia from vasoconstriction
Accidental digital injection of epinephrine causes intense vasoconstriction that can lead to ischemia of the digit, requiring treatment with phentolamine.
A 4-month-old is brought in unresponsive with bulging fontanelle, high-pitched cry, and petechial rash.
Temperature is 39.8°C.
