STUDY MATERIAL
You have just assisted with the elective endotracheal intubation of a child with respiratory failure and
a perfusing rhythm. Which of the following provides the most reliable, prompt assessment of correct
endotracheal tube placement in this child?
A. Absence of audible breath sounds over the abdomen during positive-pressure ventilation.
B. Auscultation of breath sounds over the lateral chest bilaterally plus presence of mist in the
endotracheal tube.
C. Clinical assessment of adequate bilateral breath sounds and chest expansion plus presence of
exhaled CO2 in a colormetric detection device after delivery of 6 positive-pressure ventilations.
D. Confirmation of appropriate oxygen and carbon dioxide tensions on arterial blood gas analysis.
C
An 8-year-old child was struck by a car. He arrives in the emergency department alert, anxious, and in
respiratory distress. His cervical spine is immobilized, and he is receiving a 10 L/min flow of 100%
oxygen by nonrebreathing face mask. PRimary assessment reveals respiratory rate 60/min, heart rate
150/min, systolic blood pressure 70, and SpO2 84% on supplementary oxygen. Breath sounds are
absent over the right chest, and the trachea is deviated to the left. He has weak central pulses and
absent distal pulses. Which of the following is the most appropriate immediate intervention for this
child?
, A. Provide bag-mask ventilation and call for a STAT chest x-ray
B. Perform needle decompression of the right chest and assist ventilation with a bag and mask if
necessary.
C. Establish IV access and administer a 20 mL/kg normal saline fluid bolus
D. Perform endotracheal intubation and call for a STAT chest x-ray
B
A 7-year-old boy is found unresponsive, apneic, and pulseless. CPR is ongoing. The child is intubated
and vascular access is established. The ECG monitor reveals an organized rhythm, but a pulse check
reveals no palpable pulses. Effective ventilations and compressions are resumed, and an initial IV dose
of epinephrine is administered. Which of the following therapies should you perform next?
A. Administer synchronized cardioversion at 1 J/kg
B. Administer epinephrine 0.1 mg/kg IV (0.1 mL/kg of 1:1,000)
C. Attempt defibrillation at 4 J/kg
D. Attempt to identify and treat reversible causes (using the H's and T's as a memory aid)
D
A 4-year-old male is in pulseless arrest in the pediatric intensive care unit. A code is in progress. As the
on-call physician you quickly review his chart and find that his baseline corrected QT interval on a 12-
lead ECG is prolonged. A glance at the monitor shows recurrect episodes of the above rhythm. The
boy has received one dose of epi, but continues to demonstrate the rhythm illustrated above
(Torsades de Pointes). If this rhythm persists at the next rhythm check, which medication would be
the most appropriate to administer at this time?
A. Lidocaine 1 mg/kg IV
B. Adenosine 0.1 mg/kg IV
C. Epinephrine 0.1 mg/kg (1:1000)
D. Magnesium sulfate 25 to 50 mg/kg IV
D
A pale and obtunded 3-year-old child with a history of diarrhea is brought to the hospital. Primary
assessment reveals respiratory rate of 45/min with good breath sounds bilaterally. Heart rate is
150/min, blood pressure is 90/64, and SpO2 is 96% room air. Cap refill is 5 seconds and peripheral
