A 1-year-old boy is brought to the ED for
evaluation of poor feeding, irritability, and
sweating. The child is lethargic but arousable. He
has labored breathing, very rapid pulses, and a
dusky color. His RR is 68 bpm, HR 300 bpm, and
BP 70/45 mmHg. He has weak brachial pulses
and absent radial pulses, a capillary refill of 6
secs, SpO2 85% on room air, and good bilateral
breath sounds. You administer high-flow oxygen
and place the child on a cardiac monitor and see
the rhythm shown here. The child has no history
of congenital heart disease. IV access has been
established. What therapy is most appropriate
for this child?
adenosine 0.1mg/kg IV rapid push
while a colleague provides spinal motion restriction, open the
airway with a jaw thrust and provide bag-mask ventilation
A 3-year-old boy presents with multiplesystem
trauma. The child was an unrestrained passenger
in a high-speed MVC. On primary assessment, he
is unresponsive to voice or painful stimulation.
His RR is 5 bpm, HR and pulses are 170 bpm, SBP
is 60 mmHg, capillary refill is 5 secs, and SpO2 is
75% on room air. What action should you take
first?

, A 3-year-old unresponsive, apneic child is attempt defibrillation at 30J, and
then resume CPR, beginning brought to the ED. EMS personnel report that the child
with
became unresponsive as they arrived at the compressions hospital. The child is receiving CPR with
bag-mask ventilation. The rhythm shown here is on the cardiac monitor. A biphasic manual
defibrillator is present. You quickly use the length from head to hell of the child on a color-
coded length-based resuscitation tape to estimate the approximate weight as 15kg. What
therapy is most appropriate for this child at this time?
A 4-year-old boy is in pulseless arrest in the MgSO4 25-50 mg/kg
pediatric ICU. High-quality CPR is in progress. You IV
quickly review his chart and find that this baseline-
corrected QTI on a 12lead EKG is prolonged. The
monitor shows recurrent episodes of the rhythm
shown here. The has received 1 dose of epi
0.01mg/kg, but the rhythm shown here continues.
If this rhythm persists at the next rhythm check,
what medication would be most appropriate to
administer at that time?
A 7-year-old boy is found unresponsive,identify and treat reversible causes apneic, and
pulseless. CPR is ongoing. The child is intubated, and vascular access is established.
The EKG monitor shows an organized rhythm with a HR of 45 bpm, but a pulse check
reveals no palpable pulse. High-quality CPR is resumed, and an initial IV dose of
epi is administered. What intervention should you perform next?
An 8-month-old infant is brought to the ED for give NS 20mL/kg IO
evaluation of severe diarrhea and dehydration. On rapidly
arrival to the ED, the infant becomes unresponsive,
apneic, and pulseless. You should for help and start
CPR. Another provider arrives, at which point you
switch to 2-rescuer CPR. The rhythm shown here is
seen on the cardiac monitor. The infant is intubated
and ventilated with 100% oxygen. An IO line is
established, and a dose of epi is given. While
continuing highquality CPR, what do you do next?
