DIAGRAM ILLUSTRATIONS (FREQUENTLY TESTED QUESTIONS)
A 12-year-old child being evaluated in the pediatric intensive care unit displays the following ECG waveform. The team interprets this as which arrhythmia? Second degree Second Degree Heart Block (Mobitz II) the picture shown is not the picture in the actual exam Laboratory tests are ordered for a child who has been vomiting for 3 days and is diaphoretic, tachypneic, lethargic and pale. Which test would the provider use to determine the adequacy of oxygen delivery?
Lactate We have an expert-written solution to this problem! A 9-year-old patient is presenting with decreased breath sounds, bradycardia, slowed respiratory rate and a low O2 saturation level. The provider interprets these findings as indicating which condition? Respiratory failure
A child in cardiac arrest experiences return of spontaneous circulation but is exhibiting signs of post–cardiac arrest syndrome (PCAS). The PALS resuscitation team determines that the child is experiencing a systemic response to ischemia/reperfusion. The team bases this determination on which finding(s)? Hypotension Fever Hyperglycemia A 2-year-old child arrives at the emergency department with the parents. The child is unresponsive, is not breathing and has no pulse. Two emergency department providers begin high-quality CPR. Which action(s) by the providers demonstrates high-quality CPR? Allowing the chest to recoil fully after each compression Providing ventilations that last about 1 second each Compressing the chest about 2 inches Giving 2 ventilations to every 15 compressions (15:2)
A PALS resuscitation team is preparing to defibrillate a child experiencing cardiac arrest. For which rhythm(s) would this action be appropriate? VF and pVT are shockable cardiac arrest rhythms. We have an expert-written solution to this problem! A provider is assessing a child with suspected shock. Which statement correctly describes hypotension and shock? Hypotension is not a consistent feature of shock; A provider is caring for a 4-year-old child in the urgent care clinic. Primary assessment reveals difficulty breathing and an oxygen saturation of 91%. The provider administers oxygen by nasal cannula with the goal of improving the child’s oxygen saturation above what percentage?
A child in the pediatric step-down unit is exhibiting signs of respiratory distress. When assessing this child, which circulation finding might be present? Pallor is a circulation finding that may be seen in patients with respiratory distress. We have an expert-written solution to this problem! A healthcare provider is performing a primary assessment of a child in respiratory distress. The provider documents increased work of breathing when which findings are observed? Nasal flaring, use of accessory muscles to breathe and intercostal, substernal or suprasternal retractions are all indicators of increased work or effort of breathing. Grunting and inspiratory stridor are abnormal breath sounds. We have an expert-written solution to this problem! An 11-year-old child develops unstable wide-complex tachycardia. Assessment reveals signs of significant hemodynamic compromise, but the child has a pulse. The PALS team would prepare the child for which intervention? First-line treatment for unstable wide-complex tachycardias consists of synchronized electrical cardioversion, particularly when signs of hemodynamic compromise are apparent. We have an expert-written solution to this problem!
A 4-month old infant is brought to the emergency department in cardiac arrest. Which condition would the team identify as the most common cause of cardiac arrest in an infant of this age? Sudden infant death syndrome We have an expert-written solution to this problem! A 9-year-old child is brought to the emergency department because the child suddenly collapsed at school. The child’s ECG reveals the following waveform, and primary assessment findings indicate that the child is hemodynamically unstable. Which primary assessment findings indicate this? Difficulty breathing Hypotension Mottling Decreased level of consciousness
Hypovolemic We have an expert-written solution to this problem! While performing a rapid assessment and formulating an initial impression using the Pediatric Assessment Triangle (PAT), the provider assesses the child’s circulation. Which information would be important to consider? When assessing the adequacy of circulation, consider skin color and visible mucous membranes for pallor (or gray/dusky color), cyanosis, mottling or flushing and evidence of any bleeding, including life-threatening bleeding.
Assessment of a 3-month-old infant admitted with respiratory distress reveals fever, grunting and a wet, “junky” cough. The infant’s parents said the child had a recent respiratory infection with a fever. A rapid respiratory syncytial virus (RSV) test is positive. Which condition would the provider most likely suspect as the cause? Bronchiolitis We have an expert-written solution to this problem! PALS resuscitation team notes the following ECG waveform and the child does not have a pulse. The team prepares to intervene to address which arrhythmia?
We have an expert-written solution to this problem! The PALS resuscitation team is providing care to an intubated child in cardiac arrest. Which result best determines the adequacy of the team’s chest compressions? End-tidal carbon dioxide level between 15 and 20 mmHg
The PALS team leader is conducting a debriefing session with the team. Which topic(s) would the team leader most likely address during the session? Summary of the event, including what actions were taken, Discussion of the pros and cons of the interventions, Identification of ways to improve, Evaluation of the objective data gathered during the event Assessment of a 7-year-old patient with septic shock reveals capillary refill of 3 seconds, diminished pulses, narrow pulse pressure and cool, mottled extremities. The emergency response team interprets these findings as indicating which type of septic shock? Most children in septic shock present with cold shock (i.e., delayed capillary refill, diminished pulses, peripheral vasoconstriction, narrow pulse pressure, and cool, mottled extremities) instead of warm shock.
A 10-year-old child has collapsed in the gym of the elementary school. The school nurse arrives and determines that the child is unresponsive. The school nurse then simultaneously checks for breathing and a central pulse, limiting this assessment to which time frame? 5 seconds, but no more than 10. We have an expert-written solution to this problem! A child being cared for in the pediatric telemetry unit suddenly displays the following ECG waveform. The provider prepares to intervene because the child is demonstrating which type of arrhythmia?
Supraventricular tachycardia A 6-year-old patient is brought to the emergency department after a bicycle accident. Assessment reveals tracheal deviation to the left side, chest pain on inspiration and decreased breath sounds on the right side. The provider suspects obstructive shock caused by what condition? Tension pneumothorax
Patients may have a brief period of "asystole" following the administration of adenosine. This is normal and typically self-limited. An 8-year-old child being treated in the emergency department has significant respiratory distress. The child also exhibits hives, wheezing, angioedema, tachycardia and dyspnea. The parents state that the child, who is allergic to peanuts, had eaten some popcorn that had peanuts in it. The team initiates care, preparing to administer which agent first? epi We have an expert-written solution to this problem! A 2-year-old child of unknown weight arrives at the emergency department in cardiac arrest. When preparing to administer medications, which action would be appropriate for the team to take? Tape
We have an expert-written solution to this problem! The PALS team is providing post–cardiac arrest care to an 8-year-old child in the pediatric intensive care unit. Which intervention would the team implement to achieve the primary goal of post–cardiac arrest care? ensure MAP A 12-year-old is being treated in the urgent care clinic. The mother reports that the child came home from school yesterday with a high fever, vomiting and multiple episodes of watery diarrhea. The healthcare provider obtains a rhythm strip and notes the following waveform. The provider interprets this as which type of arrhythmia? sinus tahy
