AHA PALS Precourse Test_ answered_ Updated Fall 2021/2022. 1. Parents of a 1-year-old female phoned EMS when they picked up their daughter from the babysitter. Paramedics perform an initial impres... sion revealing an obtunded infant with irregular breathing, bruises over the abdomen, abdominal distension, and cyanosis. Assisted bag-mask ventilation with 100% oxygen is initiated. On primary assessment heart rate is 36/min, peripheral pulses cannot be palpated, and central pulses are barely palpable. Cardiac monitor shows sinus bradycardia. Chest compressions are started at 15:2. In the ED the infant is intubated and ventilated, and IV access is established. The heart rate is now up to 150/min, but there are weak central pulses and no distal pulses. Systolic BP is 74. Of the following, which would be most useful in management of this infant? A. Synchronized cardioversion B. Epinephrine 0.01 mg/kg (0.1 mL/kg of 1:10,000 dilution) IV C. Rapid bolus of 20 mL/kg of isotonic crystalloid D. Atropine 0.02 mg/kg IV 2. You enter a room to perform an initial impression of a previously stable 10-year-old male and find him unresponsive and apneic. A code is called and bag-mask ventilation is performed with 100% oxygen. The cardiac monitor shows a wide-complex tachycardia. The boy has no detectable pulses so compressions and ventilations are provided. As soon as the defibrillator arrives you deliver an unsynchronized shock with 2 J/kg. The rhythm check after 2 minutes of CPR reveals VF. Y [Show More]
