PALS All Questions And 100% Correct AnswersYou are caring for an infant resuscitated after an episode of drowning. The infant is
intubated and ventilated with 100% oxygen with equal breath sounds and exhaled CO2
detected. The HR is bradycardic and the monitor displays sinus bradycardia. The skin is
cool, mottled, and moist; distal pulses are not palpable and central pulses are weak.
Intravenous access has been established. Core temperature is 37.3oC. According to the
PALS bradycardia algorithm, which of the following should be given first?
Epinephrine IV
Transcutaneous pacing
Atropine IV
Dobutamine IV infusion - ANSWER Epinephrine IV
You are treating a 5-year-old client with supraventricular tachycardia (heart rate =
220/min). The child is lethargic. The skin is pale and cool with delayed capillary refill.
Distal pulses are not palpable. Which of the following would be the best treatment to
provide without delay?
Apply cold packs to the distal upper and lower extremities Ask the child to blow through
a small straw Apply gentle pressure to the eyes bilaterally Administer synchronized
cardioversion at 0.5 to 1 J/kg - ANSWER Administer synchronized cardioversion at 0.5
to 1 J/kg
You are initiating treatment for a child in septic shock with hypotension. On high-flow
oxygen, you find that the child's respirations are adequate and SpO2 is 100%. You have
just established vascular access and obtained blood samples. Which of the following is
the next most appropriate therapy to support systemic perfusion?
Administration of repeated fluid boluses of isotonic colloid
Administration of repeated fluid boluses of isotonic crystalloid
Initiation of immediate dopamine infusion
Institute immediate dobutamine infusion - ANSWER Use repeated boluses of isotonic
crystalloid
,You are resuscitating an 8-year-old in ventricular tachycardia with pulses and good
perfusion. You have tried synchronized cardioversion that was unsuccessful. While
seeking expert consultation, it would be best to:
Administer a milrinone load
Investigate possible metabolic and toxicologic etiologies
Initiate transcutaneous overdrive pacing
Administer an unsynchronized shock - ANSWER Investigate possible metabolic and
toxicologic etiologies
You are caring for a 2-yr-old client who is unconscious, intubated, and on mechanical
ventilation. The child's heart rate suddenly decreases to 40/min and he becomes
mottled. In response to this change you would:
Increase ventilator rate
Increase tidal volume
Increase positive end-expiratory pressure (PEEP)
Using a resuscitation bag provide manual ventilation with 100% oxygen - ANSWER Using
a resuscitation bag provide manual ventilation with 100% oxygen
You are working with a 9-month-old patient in obvious respiratory distress. You started
high-flow oxygen using a non-rebreathing mask about 10 minutes ago and established
intravenous access. The infant's initial heart rate was in the range of 150/min with
strong pulses. Suddenly, the infant's respiratory rate slows to 6/min with marked
intercostals retractions, and little air movement is heard. The infant becomes cyanotic
and the heart rate slows to 95/min. Which of the following treatments would you be best
to institute now?
Epinephrine IV
Bag-mask ventilate
Magnesium sulfate IV
Intubate and ventilate - ANSWER Bag-mask ventilate
, Which of the following is likely to prove the most useful technique to identify potentially
reversible metabolic and toxic causes during the attempted resuscitation of a young
child in cardiac arrest?
Obtaining a urine sample for toxicology screen
Obtaining chest and abdominal radiographs
Obtaining a history from the caregiver or family
Obtaining a venous blood gas - ANSWER Obtaining a history from the caregiver or family
You are caring for a patient who developed a tension pneumothorax after several hours
of positive-pressure ventilation. Which of the following would be the most appropriate
site for needle decompression?
Over the third rib at the midclavicular line
Under the eighth rib at the midaxillary line
Above the fifth rib at the sternal border
Below the sixth rib at the midclavicular line - ANSWER Above the third rib at the
midclavicular line
You tried synchronized cardioversion on an infant with supraventricular tachycardia
(SVT) and poor perfusion. He remains in SVT after the first 1 J/kg shock. What do you try
now?
Synchronized cardioversion at dose of 2 J/kg
Synchronized cardioversion at dose of 4 J/kg
Un synchronized cardioversion 2 J/kg Un synchronized cardioversion, 4 J/kg - ANSWER
Synchronized cardioversion, 2 J/kg
You are managing a 5-month-old patient with a 2-day history of vomiting and diarrhea.
The patient is listless. The respiratory rate is 52/min and unlabored. The heart rate is
170/min and pulses are present but weak. Capillary refill is delayed. You are providing
high-flow oxygen, and intravenous access is in place. At this point, the most important
therapy is to:
