TRIAGE EXCELLENCE
Domain: ESI Fundamentals & Level Definitions
1. The Emergency Severity Index (ESI) is a ___-level triage algorithm.
A) 3
B) 4
C) 5
D) 6
Correct Answer: C
Rationale: ESI categorizes patients into five levels, with Level 1 being
the most urgent (immediate life-saving intervention needed) and Level 5
being the least urgent (no resources expected).
2. An ESI Level 1 patient is defined as someone who:
A) Needs two or more resources
B) Requires immediate life-saving intervention
C) Has high-risk confusion or severe pain
D) Is expected to need one resource
Correct Answer: B
Rationale: Level 1 is reserved for patients in extremis who need
immediate interventions to prevent death (e.g., intubation, CPR,
defibrillation, active seizure control).
,3. Which of the following is an example of a life-saving intervention that
would make a patient ESI Level 1?
A) IV fluids for dehydration
B) Endotracheal intubation for respiratory failure
C) Oral pain medication for headache
D) X-ray for suspected ankle fracture
Correct Answer: B
Rationale: Intubation is an immediate airway intervention to prevent
death. IV fluids, oral meds, and X-rays are resources but not life-saving
interventions.
4. After ruling out Level 1, the next question in the ESI algorithm is:
A) How many resources will the patient need?
B) Should the patient wait? (High-risk situation, confusion, or severe
pain/distress?)
C) What are the vital signs?
D) Is the patient pediatric?
Correct Answer: B
Rationale: Decision Point A asks if the patient should wait. If YES (high-
risk, confused, severe pain/distress), the patient is ESI Level 2. If NO,
proceed to resource estimation.
5. Which scenario would typically be classified as ESI Level 2?
A) Sore throat with normal vitals
B) New-onset confusion in an elderly patient
C) Simple laceration needing sutures
D) Medication refill request
Correct Answer: B
Rationale: New-onset confusion is a high-risk situation that could
indicate stroke, infection, metabolic disturbance, or other serious
conditions requiring prompt evaluation.
Domain: High-Risk Situations & Decision Point A
,6. A "high-risk situation" in ESI triage refers to:
A) Any patient over age 65
B) A condition that could deteriorate rapidly or has potential for serious
complications
C) Patients who are angry or demanding
D) Patients with insurance issues
Correct Answer: B
Rationale: High-risk situations include conditions like chest pain with
normal vitals, suicidal ideation, immunocompromised patients with
fever, or abdominal pain in pregnancy—where delay could cause harm.
7. A 45-year-old male presents with chest pain, normal vitals, and no
distress. He should be triaged as:
A) ESI Level 1
B) ESI Level 2
C) ESI Level 3
D) ESI Level 4
Correct Answer: B
Rationale: Chest pain is a high-risk complaint regardless of vitals
because it could represent acute coronary syndrome. This patient should
not wait and is Level 2.
8. Which pediatric patient would be ESI Level 2 based on high-risk
criteria?
A) 2-year-old with runny nose, normal activity
B) 3-month-old infant with fever ≥100.4°F (38°C)
C) 10-year-old with scraped knee
D) 5-year-old requesting cough syrup
Correct Answer: B
Rationale: Infants <3 months with fever are high-risk for serious
bacterial infection (sepsis, meningitis) and require immediate
evaluation, making them ESI Level 2.
, 9. A patient with sickle cell disease presents with mild pain but normal
vitals. The triage nurse should consider:
A) ESI Level 5 because vitals are normal
B) ESI Level 2 due to high-risk condition (potential for vaso-occlusive
crisis)
C) ESI Level 4 because only one resource needed
D) Discharging without evaluation
Correct Answer: B
Rationale: Patients with sickle cell disease are high-risk; even mild pain
can rapidly progress to severe crisis. They should not wait and are
typically Level 2.
10. "Severe pain or distress" as a Level 2 criterion is determined by:
A) The triage nurse's personal pain tolerance
B) Patient report, behavioral cues, and clinical judgment
C) Vital sign abnormalities only
D) The patient's age
Correct Answer: B
Rationale: Pain is subjective. The triage nurse uses patient self-report,
observed distress (grimacing, guarding, inconsolable crying), and clinical
context to determine severity.
Domain: Resource Estimation (Decision Point B)
11. In the ESI algorithm, "resources" include all EXCEPT:
A) Laboratory tests
B) Imaging studies (X-ray, CT)
C) Triage assessment and vital signs
D) Specialist consultation
Correct Answer: C
Rationale: Triage assessment, vital signs, and PO medications are NOT
counted as resources. Resources are interventions beyond basic
assessment: labs, imaging, IV fluids, procedures, consults.
