Document Content and Description Below

1. Recognize *supraventricular tachycardia*: 2. Recognize *wide-complex tachycardia*: 3. Recognize *SVT converting to sinus rhythm ... after adenosine administra- tion*: 4. What oxygen delivery system most reliably delivers a high (90% of greater) concentration of inspired oxygen to a 7-year-old child?: Nonrebreathing face mask 5. You are called to help treat an infant with severe symptomatic bradycardia (heart rate 66/min) associated with respiratory distress. Bradycardia persists despite establishment of an effective airway, oxygenation, and ventilation. There is no heart block present. What first drug should you administer?: - *Epinephrine* 6. You are part of a team attempting to resuscitate a child with ventricular fibrillation cardiac arrest.You deliver 2 unsynchronized shocks. A team mem- ber established IO access, so you give a dose of epinephrine, 0.01 mg/kg IO. At next rhythm check, persistent ventricular fibrillation is present. You administer a 4-J/kg shock and resume CPR. What drug and dose should be administered next?: *Amiodarone 5 mg/kg IO* - can be used for shock-refractory VF or pVT 7. Initial impression of a 2-year-old girl shows her to be alert with mild breath- ing 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 transmit- ted upper airway sounds with adequate distal breath sounds bilaterally. Most appropriate initial intervention for this child?: *Humidified oxygen as tolerated* 8. 7-year-old boy found unresponsive, apneic, and pulseless. CPR is ongo- ing. Child is intubated, and vascular access is established. ECG monitor shows organized rhythm with heart rate of 45/min, but a pulse check reveals no palpable pulses. High-quality CPR is resumed, and an initial IV dose of epinephrine is administered. What intervention should you perform next?: - *Identify and treat reversible causes* 9. You are caring for a 6-year-old patient who is receiving positive-pressure mechanical ventilation via an endotracheal tube. Child begins to move his head and suddenly becomes cyanotic, and his heart rate decreases. His SpO2 is 65%. You remove child from mechanical ventilator and begin to provide manual ventilation with a bag via endotracheal tube. During manual ventilation with 100% oxygen, child's color and heart rate improve slightly and his BP remains adequate. Breath sounds and chest expansion are pre- sent and adequate on right side and are present but consistently diminished on left side. Trachea not deviated, and neck veins are not distended. Suction catheter passes easily beyond tip of the endotracheal tube. Most likely cause of this child's acute deterioration?: *Tracheal tube displacement into right main bronchus* 10. You are giving chest compressions for a child in cardiac arrest. What is the proper depth of compressions for a child?: *Compress the chest at least one third the depth of the chest, about 2 inches (5 cm)* 11. During PALS, you and another rescuers begin CPR.Your colleague begins compressions, and you noticed that the compression rate is too slow. What should you say to offer constructive feedback?: *You need to compress at a rate of 100 to 120 per minute* 12. You are preparing to use a manual defibrillator in the pediatric setting. What best describes when it is appropriate to use the smaller pediatric-sized paddles?: *If the child weighs less than 10 kg or is less than 1 year old* 13. You need to provide rescue breaths to a child victim with a pulse. What is the appropriate rate for delivering breaths?: *1 breath every 3 to 5 seconds* [Show More]
