A 4-year-old is brought to triage after an accidental ingestion of an unknown quantity of amitriptyline. The child is currently somnolent with a heart rate of 160 bpm and QRS widening on the monitor. What Emergency Severity Index (ESI) level is assigned?
Show answer →ESI Level 1. Rationale: The patient requires immediate life-saving interventions. Somnolence (altered mental status), tachycardia, and ECG changes (QRS widening) indicate a life-threatening toxidrome. Level 1 is reserved for patients requiring immediate airway, breathing, or circulatory support. Exam Tip: BCEN emphasizes identifying immediate vs. urgent. Any patient needing immediate medication (like bicarbonate for TCA toxicity) or resuscitation is Level 1. Distractor: Level 2 is for high risk, but ECG changes/AMS move this to Level 1.
A 6-month-old presents with a 2-day history of vomiting and diarrhea. The infant is listless, has sunken fontanels, and a capillary refill of 4 seconds. HR 195, RR 50. According to ESI v.5, what is the most appropriate acuity level?
Show answer →ESI Level 2. Rationale: While the patient is severely dehydrated, they do not yet require immediate life-saving intervention (Level 1), but they meet High Risk criteria due to altered mental status (listless) and signs of compensated shock (tachycardia, delayed refill). ESI v.5 Danger Zone vitals for a 6-month-old include HR >180. If the clinician determines the vitals are in the danger zone, the patient must be considered for Level 2. Exam Tip: Level 2 is for patients who shouldn't wait; Level 1 is for those who CAN'T wait.
Using the Pediatric Assessment Triangle (PAT), a 3-year-old presents with audible stridor, intercostal retractions, and a barking cough, but is alert and has normal skin color. What is the PAT finding and triage priority?
Show answer →PAT: Abnormal Work of Breathing (WOB). Priority: ESI Level 2 (Urgent). Rationale: The PAT identifies Work of Breathing as the primary concern. Though Appearance and Circulation are normal, stridor at rest indicates potential airway compromise. Exam Tip: BCEN tests PAT as the across the room assessment performed before vitals. If one arm of PAT is abnormal, the child is typically at least a Level 2. If two or three are abnormal (e.g., stridor + lethargy), consider Level 1.
A 14-year-old female presents with lower abdominal pain (6/10). She is hemodynamically stable. She mentions her last period was 8 weeks ago. In the ESI algorithm, which factor determines if she is a Level 2 versus a Level 3?
Show answer →High-risk situation assessment. Rationale: A stable patient with abdominal pain usually requires multiple resources (labs, imaging, IV), making them a Level 3. However, if the triage nurse identifies a high-risk condition (e.g., suspected ectopic pregnancy with potential for rupture), they are assigned Level 2. Exam Tip: BCEN focuses on the High Risk anchor. If the nurse's clinical knowledge suggests a time-sensitive emergency exists despite stable vitals, Level 2 is the answer. Common distractor: triage based solely on pain score.
A 3-week-old infant presents with a rectal temperature of 38.4°C (101.1°F). The infant is feeding well and has a normal physical exam. What is the minimum ESI level for this patient?
Show answer →ESI Level 2. Rationale: According to ESI v.5 guidelines, any infant 28 days or younger with a fever >38.0°C (100.4°F) is automatically assigned Level 2. This is due to the high risk of serious bacterial infection (SBI) in neonates. Exam Tip: Do not be distracted by the normal exam. Age-specific fever rules are high-yield for CPEN. 1-3 months with fever may be Level 2 or 3 depending on immunization status and appearance, but the neonate (under 28 days) is always a 2.
