PALS PreTest Questions and verified solutions

PALS PreTest Questions and verified solutions You are called to help treat an infant with severe symptomatic bradycardia (heart rate 66/min) associated with respiratory distress. The bradycardia persists despite establishment of an effective airway, oxygenation, and ventilation. There is no heart block present. Which is the first drug you should administer? Initial impression of a 2yo girl shows her to be alert with mild breathing difficulty during inspiration and pale skin color. On primary assessment, she makes high-pitched inspiratory sounds (mild stridor) when agitated; otherwise, her breathing is quiet. Her spO2 is 92% on room air, and she has mild inspiratory intercostal retractions. Lung auscultation reveals transmitted upper airway sounds with adequate distal breath sounds bilaterally. Which is the most appropriate initial intervention for this child? You are part of a team attempting to resuscitate a child with ventricular fibrillation cardiac arrest. You delivered 2 unsynchronized shocks. A team member established IO access, so you give a dose of epinephrine, 0.01 mg/kg IO. At the next rhythm check, persistent ventricular fibrillation is present. You administer a 4 J/kg shock and resume CPR. Which drug and dose should be administered next? Which statement is correct about the effects of epinephrine during attempted resuscitation? A previously healthy infant with a history of vomiting and diarrhea is brought to the emergency department by her parents. During your assessment, you find that the infant responds only to painful stimulation. Which statement is correct about endotracheal drug administration during resuscitative efforts for pediatric patients? Which statement is correct about the use of calcium chloride in pediatric patients? A 9yo boy is agitated and leaning forward on the bed in obvious respiratory distress. Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of inspired oxygen to a 7yo child? Paramedics are called to the home of a 1yo child. Their initial assessment reveals a child who responds only to painful stimuli and has irregular breathing, faint central pulses, bruises over the abdomen, abdominal distention, and cyanosis A 7yo boy is found unresponsive, apneic, and pulseless. CPR is ongoing You are preparing to use a manual defibrillator in the pediatric setting. Which best describes when it is appropriate to use the smaller, pediatric-sized paddles? What compression-to-ventilation ratio should be used for 2-rescuer infant CPR? 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? You are assisting in the elective intubation of an average-sized 4yo child with respiratory failure. A colleague is retrieving the color-coded length-based tape from the resuscitation cart. Which of the following is likely to be the estimated size of the uncuffed endotracheal tube for this child? A pale and very sleepy but arousable 3yo child with a hx of diarrhea is brought to the hospital. Primary assessment reveals a respiratory rate of 45/min with good breath sounds bilaterally You are evaluating an irritable 6yo girl with mottled skin color. You assisted with the elective endotracheal intubation of a child with respiratory failure and a perfusing rhythm You and another rescuer begin CPR. Your colleague begins compressions, and you notice that the compression rate is too slow. What should you say to offer constructive feedback? A 10mo infant boy is brought to the emergency department. Your initial assessment reveals a lethargic, pale infant with slow respirations and slow, weak central pulses. A 1yo boy is brought to the emergency department for evaluation of poor feeding, irritability, and sweating During bag-mask ventilation, how should you hold the mask to make an effective seal between the child's face and the mask? An 8yo child was struck by a car. He arrives in the ED alert, anxious, and in respiratory distress. His cervical spine is immobilized, and he is receiving a 10L/min flow of 100% oxygen by nonrebreathing face mask.
