you should ensure that providers are:

Pushing hard - ensure that the chest is compressed 3/4 of the anterior-posterior diameter Pushing fast - compress at a rate of 150/min Allowing complete recoil - let the chest return to its original position between compressions Minimizing interruptions - do not permit interruptions for more than 1 minute

Answer:

Allowing complete recoil - let the chest return to its original position between compressions Question 2: You are caring for a child in persistent ventricular fibrillation. Which of the following would best describe the child's cardiac condition?The heart is not pumping blood at all The heart is beating too slowly to maintain circulation There is no electrical activity in the heart The heart is pumping so fast that it cannot fill completely between beats

Answer:

The heart is not pumping blood at all

Question 3: 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

Answer:

Soliciting a history from the caregiver or family

Question 4: Which of the following rhythms is shown on this ECG rhythm strip?

Sinus bradycardia Ventricular fibrillation (VF) Asystole Supraventricular tachycardia)

Answer:

Ventricular fibrillation (VF) Question 5: 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

Answer:

Consider possible metabolic and toxicologic causes Question 6: You are treating a 10-year-old patient after a motor vehicle crash. The patient is unresponsive and flexes his arms at the elbow in response to a painful stimulus. An endotracheal tube is in place with position confirmed. You are ventilating using a resuscitation bag with oxygen, and the child has an Spot of 95% and good chest excursion bilaterally. Blood pressure is 130/70 mm Hg and heart rate is 90/min with good perfusion. You have established intravenous access. Which of the following actions would be most appropriate at this time?Give an intravenous bolus of mannitol Provide continuous positive airway pressure (CPAP) Obtain a CT scan of the head and neck Begin manual hyperventilation

Answer:

Obtain a CT scan of the head and neck

Question 7: You are caring for a child who was resuscitated after a drowning event. The child is intubated and ventilated with 100% oxygen with equal breath sounds and exhaled CO2 detected.The heart rate is slow and the monitor shows a sinus bradycardia. The skin is cool, mottled, and moist; distal pulses are not palpable and central pulses are weak. Intravenous access has been established. The core temperature is 37.3°C. Based on the PALS bradycardia algorithm, which of the following should be provided first?Transcutaneous pacing Epinephrine IV Atropine IV Dobutamine IV infusion

Answer:

Epinephrine IV Question 8: You attempted synchronized cardioversion for an infant with supraventricular tachycardia (SVT) and poor perfusion. The SVT persists after the initial 1 J/kg shock. Which of the following should you attempt now?Synchronized cardioversion at a dose of 2 J/kg Synchronized cardioversion at a dose of 4 J/kg Unsynchronized cardioversion at a dose of 2 J/kg Unsynchronized cardioversion at a dose of 4 J/kg

Answer:

Synchronized cardioversion at a dose of 2 J/kg Question 9: 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, the heart rate is 150/min, systolic blood pressure is 70 mm Hg, and a SpO2 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?Tension Pneumothorax Cardiac temponade Severe hypovolemia Cardiac asthma

Answer:

Tension Pneumothorax Question 10: You arrive on the scene where a 12-year-old child has suddenly collapsed on the playground. The child is unresponsive, apneic, and pulseless, and CPR is in progress. A lay rescuer just arrived with the school AED, turned it on, and attached it. The AED recommends a shock. Which of the following should be done next?Attempt endotracheal intubation Obtain intravenous access Attempt defibrillation

Change the compression-to-ventilation ratio from 30:2 to 15:2

Answer:

Attempt defibrillation Question 11: You are caring for a 5-year-old patient with supraventricular tachycardia (heart rate = 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?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

Answer:

Provide synchronized cardioversion at 0.5 to 1 J/kg Question 12: 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

Answer:

Provide assisted ventilations with 100% oxygen and prepare for endotracheal intubation Question 13: You arrive on the scene of a 12-year-old child who suddenly collapsed on the playground. The child is unresponsive, apneic, and pulseless and CPR is in progress. A lay rescuer just brought the school AED, turned it on, and attached it. The AED recommends a shock. Which of the following should be done next?Obtain intravenous access Attempt defibrillation Change compressions:ventilations from 30:2 to 15:2 Attempt endotracheal intubation

Answer:

Attempt defibrillation
