A 5-year-old is found unresponsive. The nurse confirms no pulse and begins CPR. What is the correct compression-to-ventilation ratio for a single rescuer?
Answer: 30:2
A single rescuer performing CPR on a child uses a 30:2 compression-to-ventilation ratio, consistent with adult BLS guidelines.
A 14-year-old athlete collapses during practice and has no pulse. The AED identifies a shockable rhythm. What is the correct initial energy dose for a pediatric defibrillation?
Answer: 2 J/kg
The initial pediatric defibrillation dose is 2 J/kg, with subsequent shocks at 4 J/kg if the initial shock is unsuccessful.
A 3-year-old presents with stridor at rest, a barking cough, and mild retractions. The nurse assigns a croup score of 3. Which initial treatment is most appropriate?
Answer: Oral dexamethasone only
Mild to moderate croup (scores 1-5) is managed with a single oral dose of dexamethasone, which reduces airway inflammation.
A nurse is caring for a child with a suspected spinal injury after a diving accident. Which cervical immobilization device is most appropriate for initial prehospital stabilization?
Answer: Rigid cervical collar and backboard
A rigid cervical collar combined with spinal backboard immobilization provides the best initial stabilization for suspected cervical spine injury in the prehospital setting.
A 6-year-old with known peanut allergy develops urticaria, throat tightness, and hypotension after eating at a restaurant. What is the FIRST priority intervention?
Answer: Administer intramuscular epinephrine (0.01 mg/kg)
Epinephrine IM is the first and most critical intervention in anaphylaxis, as it reverses bronchospasm, vasodilation, and urticaria.
During triage, a 9-month-old presents with a bulging anterior fontanelle, high-pitched cry, and petechial rash. What is the nurse's most urgent concern?
Answer: Bacterial meningitis with possible septicemia
A bulging fontanelle, high-pitched cry, and petechial rash are classic signs of bacterial meningitis and meningococcemia, which require immediate antibiotics.
A 4-year-old is brought in after a witnessed seizure lasting 8 minutes that stopped spontaneously. The child is now post-ictal. Which diagnostic test is the highest priority?
Answer: Blood glucose measurement
Hypoglycemia is a rapidly reversible and life-threatening cause of seizures that must be identified and corrected immediately with a bedside glucose check.
