TRIAGE & INITIAL ASSESSMENT
Question 1
According to the Emergency Severity Index (ESI) triage system, which patient should be assigned
ESI Level 1?
• A. A patient with chest pain and diaphoresis
• B. A patient who is confused, lethargic, or disoriented with a high-risk presentation
• C. A patient with a simple laceration
• D. A patient with a fever and cough
Answer: B. A patient who is confused, lethargic, or disoriented with a high-risk presentation
Rationale: ESI Level 1 is for patients who require immediate life-saving intervention. Altered
mental status (confusion/lethargy) that indicates a high-risk situation qualifies as Level 1. Chest
pain with diaphoresis would be ESI Level 2. Simple lacerations and fever with cough are lower
acuity levels.
Question 2
A 6-year-old presents with stridor, drooling, and tripod positioning. What is the priority
intervention?
• A. Obtain a chest X-ray
, • B. Immediate otolaryngology (ENT) consult
• C. Prepare for emergent airway management
• D. Administer racemic epinephrine
Answer: C. Prepare for emergent airway management
Rationale: Stridor, drooling, and tripod positioning in a child are classic signs of epiglottitis, a
life-threatening airway emergency. The priority is to prepare for emergent airway management,
as the child is at imminent risk of airway obstruction. Racemic epinephrine is used for croup,
not epiglottitis. ENT consult should occur after airway is secured.
Question 3
What is the single most important predictor of the need for trauma team activation?
• A. Mechanism of injury
• B. Abnormal vital signs
• C. Age over 55
• D. Anatomic injury location
Answer: B. Abnormal vital signs
Rationale: Physiologic abnormality (GCS <14, respiratory rate <10 or >29, systolic BP <90) is the
strongest predictor of severe injury and need for full trauma team activation. While mechanism
of injury and anatomic location are important, physiologic derangement is the most reliable
indicator of life-threatening injury.
Question 4
A patient presents with an acute onset of confusion, fever, and nuchal rigidity. Which triage
level is most appropriate?
• A. ESI Level 1
• B. ESI Level 2
• C. ESI Level 3
• D. ESI Level 4
Answer: B. ESI Level 2
,Rationale: ESI Level 2 is for high-risk patients who should not wait. Confusion, fever, and nuchal
rigidity suggest meningitis, which is a high-risk condition requiring urgent evaluation and
treatment. ESI Level 1 is reserved for patients requiring immediate life-saving intervention. The
patient is not in extremis but is at high risk for deterioration.
Question 5
A 45-year-old male presents with chest pain radiating to the jaw, diaphoresis, and nausea. His
vital signs are BP 145/90, HR 110, RR 20, SpO₂ 97%. Which triage level is most appropriate?
• A. ESI Level 1
• B. ESI Level 2
• C. ESI Level 3
• D. ESI Level 4
Answer: B. ESI Level 2
Rationale: Chest pain with diaphoresis, nausea, and radiation to the jaw is a high-risk
presentation concerning for acute coronary syndrome. ESI Level 2 is for high-risk patients who
should not wait. While the patient is not requiring immediate life-saving intervention (Level 1),
the symptoms indicate potential life-threat and require rapid evaluation.
CARDIOVASCULAR EMERGENCIES
Question 6
A 62-year-old male presents with crushing substernal chest pain radiating to the left arm. ECG
shows ST-segment elevation in leads V1-V4. Which coronary artery is most likely occluded?
• A. Right coronary artery
• B. Left circumflex artery
• C. Left anterior descending artery
• D. Posterior descending artery
Answer: C. Left anterior descending artery
, Rationale: ST-segment elevation in leads V1-V4 indicates an anterior wall myocardial infarction.
The left anterior descending (LAD) artery supplies the anterior wall and interventricular septum.
The right coronary artery supplies the inferior wall (II, III, aVF). The left circumflex artery
supplies the lateral wall (I, aVL, V5-V6).
Question 7
A patient with an acute inferior wall MI develops bradycardia (HR 40) and hypotension (BP
85/50). Which intervention should be initiated first?
• A. Atropine 0.5 mg IV
• B. Epinephrine infusion
• C. Immediate transcutaneous pacing
• D. Norepinephrine infusion
Answer: A. Atropine 0.5 mg IV
Rationale: Inferior wall MIs often involve the right coronary artery, which supplies the SA and
AV nodes, leading to bradycardia and heart block. Atropine is first-line for symptomatic
bradycardia. Transcutaneous pacing is used if atropine is ineffective. Epinephrine and
norepinephrine are vasopressors for hypotension but do not specifically address
bradyarrhythmias.
Question 8
A patient presents with sudden, severe chest pain radiating to the back, with a 20 mmHg blood
pressure differential between arms. The nurse should suspect:
• A. Pulmonary embolism
• B. Aortic dissection
• C. Myocardial infarction
• D. Pericarditis
Answer: B. Aortic dissection
Rationale: Aortic dissection classically presents with sudden, severe chest pain radiating to the
back, along with pulse or blood pressure differentials between arms. This is a life-threatening
emergency requiring immediate blood pressure control and surgical consultation.
