PALS version A Exam Questions and Answers

Document Content and Description Below

1. You are caring for a child who was resuscitated after a drowning event. The child is intubated and ventilated with 100% oxygen with equal breath sounds and exhaled CO2 detected. The heart rate is s... low and the monitor shows sinus bradycardia. The skin is cool, mottled, and moist; distal pulses are not palpable and the central pulses are weak. Intravenous access has been established. The core temperature is 37.3oC. Based on the PALS bradycardia algorithm, which of the following should be provided first? Epinephrine IV Transcutaneous pacing Atropine IV Dobutamine IV infusion: Epinephrine IV 2. You are caring for a 5-year-old patient 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? 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 Provide synchronized cardioversion at 0.5 to 1 J/kg: Provide synchronized cardioversion at 0.5 to 1 J/kg 3. You are initiating treatment for a child with septic shock and hypotension. While administering high-flow oxygen you determine that the child's respi- rations 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 colloid Administer repeated fluid boluses of isotonic crystalloid Begin immediate dopamine infusion Begin immediate dobutamine infusion: Administer repeated fluid boluses of isotonic crystalloid 4. You are treating an 8-year-old with ventricular tachycardia 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 Consider possible metabolic and toxicologic causes Initiate overdrive pacing transcutaneously Deliver an unsynchronized shock: Consider possible metabolic and toxicologic causes 5. 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 Increasing tidal volume Increasing positive end-expiratory pressure (PEEP) Using a resuscitation bag provide manual ventilation with 100% oxygen: Us- ing a resuscitation bag provide manual ventilation with 100% oxygen 6. 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 intercostals 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 Intubate and ventilate: Provide bag-mask ventilation 7. Which of the following is likely to be the most helpful technique to iden- tify 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 Soliciting a history from the caregiver or family Obtaining a venous blood gas: Soliciting a history from the caregiver or family [Show More]
