PALS version B Questions and Answers 2023
You are treating an 8-year-old with ventricular tachycardia (VT) with pulses and adequate perfusion. You attempted synchronized cardioversion without success. While seeking expert consultation, it would be most appropriate to:
Administer a loading dose of milrinone
Initiate overdrive pacing transcutaneously
Consider possible metabolic and toxicologic causes
Deliver an unsynchronized shock - answer Consider possible metabolic and toxicologic causes
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 (ie, second intercostal space) at the mid-clavicular line
Under the eighth rib at the midaxillary line
Over the fifth rib at the sternal border
Under the sixth rib at the midclavicular line - answer Over the third rib (ie, second intercostal space) at the mid-clavicular line
You are initiating treatment for a child with septic shock and hypotension. While administering high-flow oxygen, you determine 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?
Administer repeated fluid boluses of isotonic colloidge
Administer repeated fluid boluses of isotonic crystalloid
Begin immediate dopamine infusion
Begin immediate dobutamine infusion - answer Administer repeated fluid boluses of isotonic crystalloid
You are caring for a 5-year-old patient with supraventricular tachycardia (SVT) (heart rate is 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?
Provide synchronized cardioversion at 0.5 to 1 J/kg
Place cold packs on the distal upper and lower extremities
Ask the child to blow through a small straw Exert light pressure on the eyes bilaterally - answer Provide synchronized cardioversion at 0.5 to 1 J/kg
You attempted synchronized cardioversion for an infant with SVT and poor perfusion. The SVT persists after the initial shock of 1 J/kg. Which of the following should you attempt now?
Synchronized cardioversion at a dose of 4 J/kg
Synchronized cardioversion at a dose of 2 J/kg
Unsynchronized cardioversion at a dose of 2 J/kg
Unsynchronized cardioversion at a dose of 4 J/kg - answer Synchronized cardioversion at a dose of 2 J/kg
You are caring for a 2-year-old unconscious patient who is intubated and receiving mechanical ventilation. The child's heart rate suddenly drops to 40/min and his color becomes mottled. You should respond to these changes by:
Increasing the ventilator rate
Using a resuscitation bag to provide manual ventilation with 100% oxygen
Increasing tidal volume
Increasing positive end-expiratory pressure (PEEP) - answer Using a resuscitation bag to provide manual ventilation with 100% oxygen
You are caring for a 9-month-old patient with pronounced respiratory distress. You initiated high-flow oxygen using a nonrebreathing mask about 10 minutes ago and established intravenous access. Initially the infant's heart rate was in the 150/min range with strong pulses. Suddenly the infant's respiratory rate falls to 6/min with significant intercostal retractions, and little air movement is heard. The infant becomes cyanotic and the heart rate decreases to 95/min. Which of the following treatments would be best
for you to provide now?
Administer epinephrine IV
Provide bag-mask ventilation
Administer magnesium sulfate IV
lntubate and ventilate - answer Provide bag-mask ventilation
You are caring for an 8-year-old child who was struck by a car. The child is alert, very anxious, and in respiratory distress. The child is receiving high-flow oxygen by face mask, has a respiratory rate of 60/min, heart rate of 150/min, systolic blood pressure of 70 mm Hg, and Spot of 86% and falling. Breath sounds and chest rise are absent over the right chest. Which of the following is the most likely cause of this child's distress?
Cardiac tamponade
Severe hypovolemia
Tension pneumothorax
Cardiac asthma - answer Tension pneumothorax
