PALS PRE COURSE SELF-ASSESSMENT TEST. VERIFIED LATEST (2026) QUESTIONS AND ANSWERS UPDATE. GENUINE EXAM UPDATE. You are caring for a 3-year-old with vomiting and diarrhea. You have established IV access. The child's pulses are palpable but faint, and the child is now lethargic. The heart rate is variable (rang, 44/min to 62/min). You begin bag-mask ventilation with 100% oxygen. When the heart rate does not improve, you begin chest compressions. The rhythm shown here is seen on the cardiac monitor. Which would be the most appropriate therapy to consider next? CORRECT ANSAtropine 0.02 mg/kg IV You are preparing to use a manual defibrillation in the pediatric setting. Which best describes when it is appropriate to use the smaller, pediatric-sized paddles? CORRECT ANSIf the child weighs less than 10 kg or is less than 1 year old. A 3-year-old boy presents with multiple-system trauma. The child was an unrestrained passenger in a high-speed motor vehicle crash. On primary assessment, he is unresponsive to voice or painful stimulation. His respiratory rate is 5/min, heart rate, and pulses re 170/min, systolic blood pressure is 60 mmHg, capillary refill is 5 seconds, and Sp02 is 75% on room air. Which action should you take first? CORRECT ANSWhile a colleague provides spinal motion restriction, open the airway with a jaw thrust and provide bag-mask ventilation. You are a caring for a 6-year-old patient who is receiving positive pressure mechanical ventilation via an endotracheal tube. The child begins to move his head and suddenly becomes cyanotic, and his heart rate decreases. His Sp02 is 65%. You remove the child from the mechanical ventilation and begin to provide manual ventilation with a bag via endotracheal tube. During manual ventilation with 100% oxygen, the child's color and heart rate improve slightly and his blood pressure remains adequate. Breath sounds and chest expansion are present and adequate on the right side and are present but consistently diminished on the left side. The trachea is not deviated and the neck veins are not distended. A suction catheter passes easily beyond the tip of the endotracheal tube. Which of the following is the most likely cause of this child's acute deterioration? CORRECT ANSTracheal tube displacement into the right main bronchus. You just assisted with the elective endotracheal intubation of a child with respiratory failure and a perfusing rhythm. Which provides a reliable, prompt assessment of correct endotracheal tube placement in this child? CORRECT ANSAdequate bilateral breath sounds and chest expansion plus detection of ETCO2 with waveform capnography. What compression to ventilation ratio should be used for 2 rescuer infant CPR? CORRECT ANS15 compressions to 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? CORRECT ANSYou need to compress at a rate of 100 to 120 per minute. You find a 10-year-old boy to be unresponsive. You shout for help, and after finding that he is not breathing and has no pulse, you and the 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 of pulseless ventricular tachycardia persists after 2 minutes of CPR, you will administer another shock. Which drug and dose should be administered next? CORRECT ANSLidocaine 1mg/kg IV You find an infant who is unresponsive, is not breathing, and does not have a pulse. You shout for nearby help, but no one arrives. What action should you take next? CORRECT ANSProvide CPR for approximately 2 minutes before leaving to activate the emergency response system. You are evaluating an irritable 6-year-old girl with mottled skin color. The patient is febrile (temperature 40C or 104 F) and her extremities are cold with capillary refill of 5 seconds. Distal pulses are absent and central pulses are weak. Heart rate is 180/min, respiratory rate is 45/min, and blood pressure is 98/56 mm Hg. How would you categorize this child's condition? CORRECT ANSCompensated shock associated with tachycardia and inadequate tissue perfusion. A 7-year-old boy is found unresponsive, apnea, 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? CORRECT ANS Identify and treat reversible causes. A pale and very sleepy but arousable 3-year-old child with a history of diarrhea is brought to the hospital. Primary assessment reveals a respiratory rate of 45/min with good breath sound bilaterally. Heart rate is 150/min, blood pressure is 90/64 mm Hg, and Sp02 is 92% in room air. Capillary refill is 5 seconds, and peripheral pulses are weak. After place the child on a nonrebreathing face mask (10L/ min flow) with 100% oxygen and obtaining vascular access, which is the most appropriate immediate treatment for this child? CORRECT ANSAdminister a bolus of 20 mL/kg isotonic crystalloid. A 1-year-old boy is brought to the emergency department for evaluation of poor feeding, irritability, and sweating. The child is lethargic but arousable. He has labored breathing, very rapid pulses, and a dusky color. His respiratory rate is 68/min, heart rate 300/min, and blood pressure 70/45 mmHg. He has weak brachial pulses and absent radial pulses, a capillary refill of 6 seconds, Sp02 85% in room air, and good bilateral breath sounds. You administer high-flow oxygen and place the child on a cardiac monitor and see the rhythm shown here. The child has no history of congenital heart disease. IV access has been established. Which therapy is most appropriate for this child? CORRECT ANSAdminister adenosine 0.1 mg/kg IV rapid push. An 8-year-old child was struck by a car. He arrives in the emergency department alert, anxious, and in respiratory distress. His cervical spine is immobilized, and he is receiving a 10 L/min flow of 100% oxygen by nonrebreathing face mask. His respiratory rate is 60/min, heart rate 150/min, systolic blood pressure 70 mm Hg, and Sp02 84%. Breath sounds are absent over the right chest but present over the left chest, and the trachea is deviated to the left. He has weak central pulses and absent distal pulses. Which intervention should be performed next? CORRECT ANSPerform needle decompression of the right chest. A 10-month-old 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? CORRECT ANSEpinephrine 0.01mg/kg IV/IO You are giving chest compressions for a child in cardiac arrest. What is the proper depth of compressions for a child? CORRECT ANS Compress the chest at least one third the depth of the chest, approximately 2 inches (5cm) You are supervising a student who is inserting an IO needle into an infant's tibia. The student asks you what she should look for to know that she has successfully inserted the needle into the bone marrow cavity. What do you tell her? CORRECT ANSFluids can be administered freely without local soft tissue swelling.
