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. The infant's respiratory rate is 40 breaths per minute, and central pulses are rapid and weak. The infant has good bilateral breath sounds, cool extremities, and a capillary refill time of more than 5 seconds. The infant's blood pressure is 85/65 mmHg, and glucose is 30 mg/dL (1.65 mmol/L). You administer 100% oxygen via face mask and start an IV. Which treatment is most appropriate for this infant? - ANSWER Administer a bolus of isotonic crystalloid 20 ml/kg over 5-20 minutes, and also give D25W 2-4 ml/kg IV
A 9yo boy is agitated and leaning forward on the bed in obvious respiratory distress. The patient is speaking in short phrases and tells you that he has asthma but does not carry an inhaler. He has nasal flaring, severe suprasternal and intercostal retractions, and decreased air movement with prolonged expiratory time and wheezing. You administer 100% oxygen by a nonrebreathing mask. His spO2 is 92%. Which med do you prepare to give to this patient? - ANSWER Albuterol (duh)
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. Bag-mask ventilation with 100% oxygen is initiated. The child's heart rate is 36/min. Peripheral pulses cannot be palpated, and central pulses are barely palpable. The cardiac monitor shows sinus bradycardia. Two-rescuer CPR is started. Upon arrival to the emergency department, the child is intubated and ventilated with 100% oxygen, and IV access is established. The heart rate is now 150/min with weak central pulses but no distal pulses. Systolic blood pressure is 74 mmHg. Which intervention should be provided next? - ANSWER Rapid bolus of 20ml/kg of isotonic crystalloid
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? - ANSWER Epinephrine
Which statement is correct about the use of calcium chloride in pediatric patients? - ANSWER Routine administration is not indicated during cardiac arrest
Which statement is correct about endotracheal drug administration during resuscitative efforts for pediatric patients? - ANSWER It is the least desirable route of administration
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? - ANSWER Humidified oxygen as tolerated
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? - ANSWER Amiodarone 5 mg/kg IO
Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of inspired oxygen to a 7yo child? - ANSWER Nonrebreathing face mask
Which statement is correct about the effects of epinephrine during attempted resuscitation? - ANSWER Epinephrine stimulates spontaneous contractions when asystole is present
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. One team member begins ventilation with a bag-mask device with 100% oxygen. A second team member attaches the monitor/defibrillator and obtains vital signs while a third team member attempts to establish IV/IO access. The patient's heart rate is 38/min with the rhythm shown here. The infant's blood pressure is 58/38 mmHg, and capillary refill is 4 seconds. His central pulses remain weak, and distal pulses cannot be palpated. Chest compressions are started and IO access is obtained. Which medication do you anticipate will be given next? - ANSWER Epinephrine 0.01 mg/kg IV/IO
A 7yo boy is found unresponsive, apneic, and pulseless. CPR is ongoing. The child is intubated, and vascular access is established. The ECG monitor shows an organized rhythm with a 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. Which intervention should you perform next? - ANSWER Identify and treat reversible causes
You find a 10yo boy to be unresponsive. You shout for help, and after finding that he is not breathing and has no pulse, you and a colleague begin CPR. Another colleague activates the emergency response system, brings the emergency equipment, and places the child on a cardiac monitor/defibrillator, which reveals the rhythm shown here. You attempt defibrillation at 2 J/kg and give 2 minutes of CPR. The rhythm persists at the second rhythm check, at which point you attempt defibrillation with 4 J/kg. A fourth colleague arrives, starts an IV, and administers 1 dose of epinephrine 0.01 mg/kg. If ventricular fibrillation or pulseless ventricular tachycardia persists after 2 minutes of CPR, you will administer another shock. Which drug and dose should be administered next? - ANSWER Lidocaine 1 mg/kg IV
A 3yo boy presents with multiple-system trauma. The child was an unrestrained passenger in a high-speed MVC. On primary assessment, he is unresponsive to voice or painful stimulation. His respiratory rate is 5/min, heart rate and pulses are 170/min, systolic BP is 60 mmHg, capillary refill is 5 seconds, and spO2 is 75% on room air. Which action should you take first? - ANSWER While a colleague provides spinal motion restriction, open the airway with a jaw thrust and provide bag-mask ventilation
You are alone and witness a child suddenly collapse. There is no suspected head or neck injury. A colleague responded to your shout for help and is activating the emergency response system and is retrieving the resuscitation equipment, including a defibrillator. After delivering 30 compressions, what would be your next action? - ANSWER Open the airway with a head tilt-chin lift maneuver and give 2 breaths
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? - ANSWER "You need to compress at a rate of 100-120 per minute."
You are caring for a 6yo patient who is receiving positive-pressure mechanical ventilation via an endotracheal tube. The child begins to move his head and suddenly
