PALS pr etest Exa m Questions And Answers @ 2023 Clinical clue: heart rate 300/min - Answer Supraventricular tachycardia Clinical clues: no consistent heart rate detected; no detectable pulses - Answer Ventricular fibrillation Clinical clues: initial rhythm associated with no detectable pulses - Answer VF with successful defibrillation and resumption of organized rhythm Clinical clues: heart rate 200/bpm no detectable pulses - Answer Torsades de pointes Clinical clues: heart rate 44/min; no detectable pulses - Answer PEA Clinical clue: no detectable pulses - Answer Asystole Clinical clues: Ages 8 years; heart rate 78/min - Answer Normal sinus rhythm Clinical clues: heart rate 150/bpm - Answer Wide-complex tachycardia Clinical clues: Age 7 years; heart rate 38/min - Answer Sinus bradycardia Clinical clues: initial rhythm associated with heart rate 300/min - Answer SVT converting to sinus rhythm after adenosine administration Clinical clues: febrile infant; heart rate 188/min - Answer Sinus tachycardia Clinical clues: age 3 months; heart rate 65/min - Answer Sinus bradycardia Clinical clue: heart rate 214/min - Answer wide-complex tachycardia 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 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-pitches 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 Which statement is correct about endotracheal drug administration during resuscitative efforts for pediatric patients? - Answer It is the least desirable route of administration 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 now 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 20 mL/kg of isotonic crystalloid Which statement is correct about the effects of epinephrine during attempte d resuscitation? - Answer Epinephrine stimulates spontaneous contractions when asystole is present 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 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 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 expiratory 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 Which statement is correct about the use of calcium chloride in pediatric patients? - Answer Routine administration is not indicated during cardiac arrest
