PALS PRECOURSE SELF-ASSESSMENT QUESTIONS
WITH ACTUAL ANSWERS
You assisted with the elective endotracheal intubation of a child with respiratory failure and a
perfusing rhythm. Which provides a reliable, prompt assessment of correct endotracheal tube
placement in this child? ✔️✔️Adequate bilateral breath sounds and chest expansion plus
detection of ETCO2 with waveform capnography
Which ratio of compressions to breaths should be used for 1-rescuer child CPR ✔️✔️30
compressions to 2 breaths
You are caring for a 3yo with vomiting and diarrhea. You have established IV access. The child's
pulses are palpable but faint, and the child is now lethargic. The heart rate is variable (range,
44/min to 62/min). You begin bag-mask ventilation with 100% oxygen. When the heart rate does
not improve, you begin chest compressions. The rhythm shown here is seen on the cardiac
monitor. Which would be the most appropriate therapy to consider next? ✔️✔️Atropine 0.02
mg/kg IV
What compression-to-ventilation ratio should be used for 2-rescuer infant CPR? ✔️✔️15
compressions to 2 breaths
You are assisting in the elective intubation of an average-sized 4yo child with respiratory failure.
A colleague is retrieving the color-coded length-based tape from the resuscitation cart. Which of
, the following is likely to be the estimated size of the uncuffed endotracheal tube for this child?
✔️✔️5mm tube
A 4yo boy is in pulseless arrest in the PICU. High-quality CPR is in progress. You quickly
review his chart and find that his baseline-corrected QT 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?
✔️✔️Magnesium sulfate 25-50 mg/kg IV
You are preparing to use a manual defibrillator in the pediatric setting. Which best describes
when it is appropriate to use the smaller, pediatric-sized paddles? ✔️✔️If the child weighs less
than 10kg or is less than 1 year old
An 18mo child has a 1 week hx 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, spO2 is 65% on room air, and capillary refill is less than 2
seconds. Which are the most immediate interventions for this toddler? ✔️✔️Open the airway
and provide positive-pressure ventilation using 100% oxygen and a bag-mask device
A child becomes unresponsive in the emergency department and is not breathing. You are
uncertain if a faint pulse is present. You shout for help and provide ventilation with 100%
