PALS precourse assessment/ 50 Random Q&A
To Help Ace the Exam/ 2024-2025.
A 1yo boy is brought to the emergency department 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 respiratory rate is 68/min,
heart rate 300/min, and blood pressure 70/45 mmHg. He has weak brachial pulses
and absent radial pulses, a capillary refill of 6 seconds, 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. Which therapy is most
appropriate for this child? - Answer: Administer adenosine 0.1 mg/kg IV rapid
push

, During bag-mask ventilation, how should you hold the mask to make an effective
seal between the child's face and the mask? - Answer: Position your fingers using
the E-C clamp technique
A 3yo unresponsive, apneic child is brought to the emergency department. EMS
personnel report that the child became unresponsive as they arrived at the
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 of the child on a color-coded length-based
resuscitation tape to estimate the approximate weight as 15kg. Which therapy is
most appropriate for this child at this time? - Answer: Attempt defibrillation at 30
J, and then resume CPR, beginning with compressions
You find an infant who is unresponsive, is not breathing, and does not have a
pulse. You shout for nearby help, but no one arrives. What action should you take
next? - Answer: Provide CPR for about 2 minutes before leaving to activate the
emergency response system
SVT converting to sinus rhythm after adenosine administration
Sinus bradycardia
