Which intraosseous (IO) site is generally preferred for rapid vascular access in a child in cardiac arrest?
Answer: Proximal tibia
The proximal tibia is the preferred IO site in children due to ease of access and large marrow cavity.
A child arrests due to suspected tension pneumothorax (T cause). What is the immediate intervention?
Answer: Needle thoracostomy
Needle thoracostomy (decompression) at the 2nd intercostal space mid-clavicular line relieves tension pneumothorax.
Lidocaine is an alternative antiarrhythmic to amiodarone in pediatric cardiac arrest. What is its IV/IO dose?
Answer: 1 mg/kg
Lidocaine 1 mg/kg IV/IO is the PALS dose for shock-refractory VF/pVT when amiodarone is unavailable.
After ROSC is achieved in a pediatric cardiac arrest patient, what SpO2 target should be maintained to avoid hyperoxia?
Answer: 94-99%
Post-ROSC, titrate oxygen to maintain SpO2 94-99% to avoid both hypoxia and harmful hyperoxia.
Which finding on waveform capnography (EtCO2) during CPR suggests effective compressions and possible ROSC?
Answer: Sudden rise in EtCO2 to > 40 mmHg
A sudden increase in EtCO2 above 40 mmHg during CPR indicates ROSC due to restored pulmonary blood flow.
A child with hypovolemic shock secondary to trauma arrests. Which fluid is given first to address this reversible T cause?
Answer: Normal saline 20 mL/kg bolus
Normal saline (or LR) 20 mL/kg IV/IO bolus is given to rapidly address hypovolemia as a reversible cause of arrest.
What is the minimum acceptable EtCO2 value during CPR that suggests adequate compression quality?
Answer: ≥ 10-15 mmHg
EtCO2 ≥ 10-15 mmHg during CPR suggests adequate cardiac output; values below this indicate poor compression quality.
