PALS PreTest Exam With Complete Solution @ 2023 Graded A+ Which oxygen delivery system most reliably delivers a high (90% or greater) concentration of inspired oxygen to a 7-year-old child? - Answer Nonrebreathing f ace mask Which statement is correct about the effects of epinephrine during attemp ted resuscitation? - Answer Epinephrine stimulates spontaneous contractions when asystole is present 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 I O access, so you give a dose of epinephrine, 0.01 mg/kg IO. At the next rhythm ch eck, 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 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 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 t he 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 capillary refill time of more than 5 seconds. The infant's blood pressure is 85/65 mm Hg, and glucose is 30 mg/dL (1.65 mmol/L). You administer 100% oxygen via face mask and start an IV. Which treatment is the most ap propriate for this infant? - Answer Administer a bolus of isotonic crystalloid 20 mL/kg over 5 to 20 minutes, and also give D25W 2 to 4 mL/kg IV 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 A 9-year-old 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 respiratory time and wheezing. You administer 100% oxygen by a nonrebreathing mask. His SpO2 is 92%. Which medication do you prepare to give to this patient? - Answer Albuterol Paramedics are called to the home of a 1-year-old 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% oxyg en, and IV access is established. The heart rate is no 150/min with weak central pulses but no distal pulses. Systolic blood pressure is 74 mm Hg. Which intervention should be provided next? - Answer Rapid bolus of 20ml/kg of isotonic crystalloid Initial impression of a 2- year-old 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 soun d bilaterally. Which is the most appropriate initial intervention for this child? - Answer Humidified oxygen as tolerated An 8-month-old infant is brought to the emergency department for evaluatio n of severe diarrhea and dehydration. On arrival to the emergency department, the infant become unresponsive, apneic, and pulseless. You should for help and start CPR. Another provider arrives, at which point you switch to 2-rescuer CPR. The rhythm shown here is seen on the cardiac monitor. The infant is intubated and ventilated with 100% oxyge n. An IO line is established, and a dose of epinephrine is given. While continuing high -
quality CPR, what do you do next? - Answer Give normal saline 20 mL/kg IO rapidly 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 What ratio of compressions to breaths should be used for 1-rescuer child CPR? - Answer 30 compressions to 2 breaths 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%
