A 4-year-old boy is in pulseless arrest in the pediatric intensive care unit. High-
quality CPR is in progress. You quickly review his chart and find that his baseline-
corrected OT interval on a 12-lead ECG is prolonged. The monitor shows recurrent
episodes of the rhythm shown here. The patient has received 1 dose of
epinephrine 0.01 mg/kg, but the rhythm shown here continues. If this rhythm
persists at the next rhythm check, which medication would be most appropriate
to administer at that time? - CORRECT ANSWER-Magnesium sulfate 25 to 50
mg/kg IV
What ratio of compressions to breaths should be used for 1-rescuer child CPR? -
CORRECT ANSWER-30 compressions to 2 breaths
An 18-month-old child has a 1-week history of cough and runny nose. The child
has diffuse cyanosis and is responsive only to painful stimulation with slow
respirations and rapid central pulses. The child's respiratory rate has decreased
from 65/min to 10/min, severe inspiratory intercostal retractions are present,
heart rate is 160/min, SpOz is 65% in room air, and capillary refill is less than 2
seconds. Which are the most appropriate immediate interventions for this
, toddler? - CORRECT ANSWER-Open the airway and provide positive-pressure
ventilation using 100% oxygen and a bag-mask device
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 shows an
organized rhythm with a heart rate of 45/min, but a pulse check reveals no
palpable pulses. High-quality CPR is resumed, and an initial IV dose of epinephrine
is administered. Which intervention should you perform next? - CORRECT
ANSWER-Identify and treat reversible causes
You are evaluating an irritable 6-year-old girl with mottled skin color. The patient
is febrile (temperature 40°C [104°FI), and her extremities are cold with capillary
refill of 5 seconds. Distal pulses are absent and central pulses are weak. Heart rate
is 180/min, respiratory rate is 45/min, and blood pressure is 98/56 mm Hg. How
would you categorize this child's condition? - CORRECT ANSWER-
Compensated shock associated with tachycardia and inadequate tissue perfusion
Identify the rhythm. - CORRECT ANSWER-Ventricular Fibrillation (VF)
Identify the rhythm. - CORRECT ANSWER-Normal Sinus Rhythm
