AHA PALS PRACTICE EXAM (100 OUT OF 100) QUESTIONS AND ANSWERS. ACTUAL ACTUAL EXAM UPDATE. ALREADY G RATED A+. A 5-year-old child presents with lethargy, increased work of breathing, and pale color. The primary assessment reveals that the airway is open and the respiratory rate is 30/min, with crackles heard on auscultation. The cardiac monitor shows sinus tachycardia at a rate of 165/min. The pulse oximeter displays an oxygen saturation of 95% and a pulse rate of 93/min. On the basis of this information, which of the following provides the best interpretation of the oxygen saturation of 95% by pulse oximetry? - Correct Answer: -Unreliable; supplementary oxygen should be administered A 3-year-old child was recently diagnosed with leukemia and has been treated with chemotherapy. The child presents with lethargy and a high fever. Heart rate is 195/min, respiratory rate is 36/min, blood pressure is 85/40 mm Hg, and capillary refill time is less than 2 seconds. What is the child's most likely condition? - Correct Answer: -Septic shock A 2-week-old infant presents with irritability and a history of poor feeding. Blood pressure is 55/40 mm Hg. What term describes this infant's blood pressure? - Correct Answer: -Hypotensive During a resuscitation attempt, the team leader orders an initial dose of epinephrine at 0.1 mg/kg to be given 10. What should the team member do? - Correct Answer: -Respectfully ask the team leader to clarify the dose Which of the following is a characteristic of respiratory failure? - Correct Answer: -Inadequate oxygenation and/or ventilation Which of the following is most likely to produce a prolonged expiratory phase and wheezing? - Correct Answer: -Lower airway obstruction A 4-year-old child presents with seizures and irregular respirations. The seizures stopped a few minutes ago. Which of the following most likely to be abnormal? - Correct Answer: -Control of breathing What abnormality is most likely to be present in children with acute respiratory distress caused by lung tissue disease? - Correct Answer: -Decreased oxygen saturation An alert 2-year-old child with an increased work of breathing and pink color is being evaluated. Heart rate is 110/min, and respiratory rate is 30/min. What would best describe this patient's condition? - Correct Answer: -Respiratory distress The parents of a 7-year-old child who is undergoing chemotherapy report that the child has been febrile and has not been feeling well, with recent onset of lethargy. Assessment reveals the following: The child is difficult to arouse, with pale color. The child's heart rate is 160/min, respiratory rate is 30/min, blood pressure is 76/45 mm Hg, capillary refill time is 5 to 6 seconds, and temperature is 103°F (39.4°C). What is the most appropriate intervention? - Correct Answer: -Obtain vascular access and administer 20 mL/kg of isotonic crystalloid over 5 to 10 minutes A 2-year-old child presents with a 4-day history of vomiting. The initial impression reveals an unresponsive child with intermittent apnea and mottled color. Heart rate is 166/min, respiratory rate is now being supported with bag-mask ventilation, capillary refill time is 5 to 6 seconds, and temperature is 102°F (38.9°C). What is the best method of establishing immediate vascular access? - Correct Answer: -Place an intraosseous line What is the appropriate fluid bolus to administer for a child with hypovolemic shock with adequate myocardial function? - Correct Answer: -20 mL/kg normal saline An alert toddler presents with a barking cough, moderate stridor, and moderate retractions. The child's color is pink. What is the most appropriate initial intervention? - Correct Answer: -Administer nebulized epinephrine An 8-year-old child presents with a history of vomiting and diarrhea. The child has the following vital signs: heart rate 168/min, respiratory rate 15/min, blood pressure 9060 mm Hg, and temperature 98.6°F (37°C). The child's capillary refill time is 4 seconds. After 2 IV boluses of normal saline (20 mL/kg each), the child's vital signs are now as follows: heart rate 130/min, respiratory rate 16/min, blood pressure 94/62 mm Hg, capillary refill 2 seconds, and temperature 98.6°F (37°C). The child's urine output is 1 to 2 mL/kg in the past hour. The child is still lethargic. What diagnostic tests or information should be obtained first? - Correct Answer: -Glucose A 15-year-old boy presents with acute onset of severe respiratory distress, with retractions and an oxygen saturation of 85%. His trachea is deviated to the right, and there are no breath sounds on the left. His heart rate is 140/min, his blood pressure is 84/60 mm Hg, and his capillary refill time is 3 seconds. What is the most appropriate intervention? - Correct Answer: -Perform needle decompression on the left chest A 4-year-old is being treated for hypovolemic shock and has received a single fluid bolus of 20 mL/kg of normal saline. On reevaluation the child remains anxious, with a heart rate of 140/min, a blood pressure of 84/54 mm Hg, and a capillary refill time of 4 seconds. What describes this patient's condition? - Correct Answer: -Compensated shock
