You are treating an 8-year-old with ventricular tachycardia (VT) 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 Initiate overdrive pacing transcutaneously Consider possible metabolic and toxicologic causes Deliver an unsynchronized shock Consider possible metabolic and toxicologic causes You are caring for a patient who developed a tension pneumothorax after several hours of positive-pressure ventilation. Which of the following would be the most appropriate site for needle decompression? Over the third rib (ie, second intercostal space) at the mid-clavicular line Under the eighth rib at the midaxillary line Over the fifth rib at the sternal border Under the sixth rib at the midclavicular line Over the third rib (ie, second intercostal space) at the mid-clavicular line 00:40 01:01 You are initiating treatment for a child with septic shock and hypotension. While administering high-flow oxygen, you determine that the child's respirations 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 colloidge Administer repeated fluid boluses of isotonic crystalloid Begin immediate dopamine infusion Begin immediate dobutamine infusion Administer repeated fluid boluses of isotonic crystalloid You are caring for a 5-year-old patient with supraventricular tachycardia (SVT) (heart rate is 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? Provide synchronized cardioversion at 0.5 to 1 J/kg 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 You attempted synchronized cardioversion for an infant with SVT and poor perfusion. The SVT persists after the initial shock of 1 J/kg. Which of the following should you attempt now? Synchronized cardioversion at a dose of 4 J/kg Synchronized cardioversion at a dose of 2 J/kg Unsynchronized cardioversion at a dose of 2 J/kg Unsynchronized cardioversion at a dose of 4 J/kg Synchronized cardioversion at a dose of 2 J/kg 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 Using a resuscitation bag to provide manual ventilation with 100% oxygen Increasing tidal volume Increasing positive end-expiratory pressure (PEEP) Using a resuscitation bag to provide manual ventilation with 100% oxygen 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 intercostal 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 lntubate and ventilate Provide bag-mask ventilation You are caring for an 8-year-old child who was struck by a car. The child is alert, very anxious, and in respiratory distress. The child is receiving high-flow oxygen by face mask, has a respiratory rate of 60/min, heart rate of 150/min, systolic blood pressure of 70 mm Hg, and Spot of 86% and falling. Breath sounds and chest rise are absent over the right chest. Which of the following is the most likely cause of this child's distress? Cardiac tamponade Severe hypovolemia Tension pneumothorax Cardiac asthma Tension pneumothorax Which of the following is likely to be the most helpful technique to identify potentially reversible metabolic and toxic causes during the attempted resuscitation of a young child in cardiac arrest? Soliciting a history from the caregiver or family Obtaining a urine sample for toxicology screen Obtaining chest and abdominal radiographs Obtaining a venous blood gas Soliciting a history from the caregiver or family Which of the following rhythms is shown on this ECG rhythm strip? Sinus bradycardia Ventricular fibrillation (VF) Asystole Supraventricular tachycardia) Ventricular fibrillation (VF) You are caring for an 8-month-old with bradycardia and very poor perfusion that has persisted despite effective ventilations with high-flow oxygen. You should begin chest compressions if the heart rate is: More than 200/min More than 150/min Less than 100/min Less than 60/min Less than 60/min You are caring for a 3-year-old with myocarditis and heart failure. She has become poorly responsive to a sternal rub and is difficult to rouse. She has a sinus rhythm with a heart rate of 175/min, and a blood pressure of 88/65 mm Hg. Her skin is cool and mottled, capillary refill time is 5 seconds and she has barely palpable distal pulses. Oxygen saturation is 90% on high-flow, high-concentration oxygen by face mask. Her respirations are labored at 50/min with moderate retractions, and crackles are heard at the bases. Which of the following would be the most appropriate therapy for this child? Obtain a STAT echocardiogram and chest x-ray Perform synchronized cardioversion at 0.5 joules/kg Provide assisted ventilations with 100% oxygen and prepare for endotracheal intubation Administer epinephrine 0.1 mL/kg of 1:10,000 solution IV Provide assisted ventilations with 100% oxygen and prepare for endotracheal intubation
