Introduction:
The Emergency Nurse Practitioner (ENP) Ultimate Exam 2026/2027 assesses a
candidate's comprehensive knowledge and clinical reasoning essential for
advanced emergency nursing practice. It evaluates foundational theory,
applied professional knowledge, and the critical thinking skills required to
manage high-acuity, undifferentiated patient presentations. The exam
structure includes multiple-choice questions and scenario-based assessments
designed to test real-world application and decision-making under pressure.
This assessment ensures candidates are fully prepared to deliver safe, ethical,
,and evidence-based emergency care in accordance with the AANPCB ENP
certification blueprint.
SECTION ONE: QUESTIONS 1–100
1. A 45-year-old male presents to the emergency department with sudden
onset of severe retrosternal chest pain radiating to his back. He is
hypertensive and diaphoretic. On examination, you note a blood pressure
differential of 25 mmHg between his right and left arms. What is the most
likely diagnosis?
A. Acute myocardial infarction with cardiogenic shock
B. Tension pneumothorax
C. Acute aortic dissection
D. Pulmonary embolism with acute right heart strain
C. Acute aortic dissection
RATIONALE: The clinical presentation of sudden onset severe
retrosternal chest pain radiating to the back, hypertension, diaphoresis, and a
blood pressure differential between arms (>20 mmHg) is classic for acute
aortic dissection. This blood pressure differential occurs due to involvement
of the subclavian arteries.
2. A 28-year-old female with no past medical history presents with acute
onset severe headache, fever, neck stiffness, and petechial rash. What is the
most appropriate initial action?
A. Obtain CT imaging before lumbar puncture to rule out contraindications
B. Initiate empiric antibiotics immediately without waiting for confirmatory
testing
C. Perform lumbar puncture and await cerebrospinal fluid results before
starting treatment
D. Start supportive care and observe for 2-4 hours before initiating antibiotics
, B. Initiate empiric antibiotics immediately without waiting for
confirmatory testing
RATIONALE: Bacterial meningitis is a life-threatening emergency where
every hour of delayed treatment increases morbidity and mortality. The
classic triad of fever, headache, and neck stiffness, combined with petechial
rash, constitutes meningitis until proven otherwise. Empiric antibiotic
administration should occur within one hour of clinical suspicion.
3. A 67-year-old male with a history of COPD and smoking presents with
acute dyspnea. On examination, his blood pressure is 92/54 mmHg, heart rate
is 118 bpm, respiratory rate is 32, and oxygen saturation is 88% on room air.
Breath sounds are diminished on the right side with hyperresonance to
percussion. What is the most appropriate immediate intervention?
A. Emergent needle decompression
B. Administration of intravenous furosemide
C. Initiation of non-invasive positive pressure ventilation
D. Obtain stat portable chest radiograph
A. Emergent needle decompression
RATIONALE: The presentation of acute dyspnea, hypotension,
tachycardia, hypoxia, unilateral diminished breath sounds, and
hyperresonance is consistent with tension pneumothorax, which is a clinical
diagnosis requiring immediate needle decompression without waiting for
radiographic confirmation.
4. According to the Emergency Medical Treatment and Active Labor Act
(EMTALA), a medical screening exam (MSE) must be performed on any
individual who:
A. Has health insurance coverage
B. Presents to the emergency department requesting examination or
treatment
, C. Is transferred from another facility
D. Can pay for services
B. Presents to the emergency department requesting examination or
treatment
RATIONALE: EMTALA requires that any individual who comes to the
emergency department and requests examination or treatment for a medical
condition must receive an appropriate medical screening examination
regardless of insurance status or ability to pay.
5. A 55-year-old female presents with sudden onset of "the worst headache of
my life." She describes it as a thunderclap headache that reached maximum
intensity within seconds. What is the most likely diagnosis?
A. Migraine with aura
B. Subarachnoid hemorrhage
C. Tension headache
D. Cluster headache
B. Subarachnoid hemorrhage
RATIONALE: A thunderclap headache that reaches maximum intensity
within seconds is the classic presentation of subarachnoid hemorrhage, most
commonly from a ruptured berry aneurysm. Immediate non-contrast CT
head followed by lumbar puncture if CT is negative is the diagnostic
approach.
6. A 72-year-old male with a history of atrial fibrillation presents with acute
onset right-sided weakness and aphasia. Symptoms began approximately 90
minutes ago. His blood pressure is 180/95 mmHg. What is the most
appropriate next step?
A. Administer aspirin 325 mg orally
B. Obtain emergent non-contrast CT head
C. Administer intravenous labetalol
D. Initiate therapeutic heparin infusion
