PALS- Practical Application Exam.

PALS- Practical Application Exam. 1. What compression-to-ventilation ratio should be used C) 15 compressions to 2 for 2-rescuer infant CPR? A) 20 compressions to 2 breaths B) 5 compressions to 1 breath C) 15 compressions to 2 breaths D) 30 compressions to 2 breaths 2. You are assisting in the elective intubation of an av- erage-sized 4-year-old child with respiratory failure. A colleague is retrieving the color-coded length-based tape from the resuscitation cart. Which of the follow- ing is likely to be the estimated size of the uncuffed endotracheal tube for this child? A) 4-mm tube B) 5-mm tube C) 3-mm D) 6-mm tube 3. An 8-year-old child was struck by a car. He arrives in the emergency department alert, anxious, and in respiratory distress. His cervical spine is immobilized, and he is receiving a 10-L/min flow of 100% oxygen by nonrebreathing face mask. His respiratory rate is 60/min, heart rate 150/min, systolic blood pressure 70 mm Hg, and SpO2 84%. Breath sounds are absent over breaths B) 5-mm tube C) Perform needle decom- pression of the chest the right chest but present over the left chest, and the trachea is deviated to the left. He has weak central pulses and absent distal pulses. Which intervention should be performed next? A) Establish IV access B) Provide bag-mask ventilation C) Perform needle decompression of the chest D) Perform endotracheal intubation 4. Why is allowing complete chest recoil important when A) The heart will refill with performing high-quality CPR? A) The heart will refill with blood between compres- sions B) The rate of chest compressions will increase C) There will be a reduction in rescuer fatigue D) It will reduce the risk of rib fractures 5. You find an infant who is unresponsive, is not breath- ing, and does not have a pulse. You shout for nearby help, but no one arrives. What action should you take next? A) Provide CPR for approximately 2 minutes before leaving to activate the emergency response system B) Activate the emergency response system after giv- blood between compres- sions A) Provide CPR for ap- proximately 2 minutes be- fore leaving to activate the emergency response sys- tem ing CPR for 90 seconds C) Activate the emergency system after giving CPR for 10 minutes D) Provide CPR for 60 seconds before leaving to acti- vate the emergency response system 6. A 1-year-old boy is brought to the emergency depart- ment 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 mm Hg. He has weak brachial pulses and absent radial pulses, a capillary refill of 6 seconds, SpO2 85% in room air, and good bilater- al 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 con- genital heart disease. IV access has been established. Which therapy is most appropriate for this child? A) Consult with pediatric cardiology B) Administer isotonic crystalloid fluid of 20 mL/kg C) Administer adenosine 0.1 mg/kg IV rapid push D) Perform immediate defibrillation
