Introduction:
This Emergency Nurse Practitioner Diagnostic Readiness Test is a comprehensive assessment designed to evaluate
the candidate's clinical competence and readiness for certification examination. The exam measures advanced
diagnostic reasoning, pharmacologic knowledge, and the ability to apply evidence-based guidelines in the care of
patients presenting with emergent and urgent conditions. The structure includes multiple-choice questions that
,test foundational theory, regulatory compliance, ethical decision-making, and critical thinking. Each question
emphasizes real-world application, challenging the test-taker to synthesize complex information, prioritize
interventions, and make sound clinical judgments. Success on this examination indicates mastery of the core
competencies required for safe, effective, and independent practice as an Emergency Nurse Practitioner.
SECTION ONE: QUESTIONS 1–100
1. A 52-year-old male presents to the emergency department with acute onset chest pain, diaphoresis, and
shortness of breath. An EKG shows ST-segment elevations in leads V1-V4. His blood pressure is 95/55 mmHg
and heart rate is 115 bpm. Which of the following is the most appropriate initial treatment?
A. Sublingual nitroglycerin
B. Aspirin 324 mg chewable
C. Morphine sulfate
D. Oxygen at 4 L/min
🟢 B. Aspirin 324 mg chewable
🔴 RATIONALE: Aspirin is the most critical initial treatment for STEMI to reduce mortality. It should be chewed
immediately to achieve rapid antiplatelet effect. Nitroglycerin and morphine may be used for pain control, but
aspirin is the priority.
,2. A 28-year-old female presents with a sudden onset of severe headache, nausea, and vomiting. She reports
that this is the worst headache of her life. A CT scan of the head is negative. Which of the following is the
most appropriate next step in diagnosis?
A. MRI of the brain
B. Lumbar puncture
C. CT angiography
D. EEG
🟢 B. Lumbar puncture
🔴 RATIONALE: A lumbar puncture is indicated when subarachnoid hemorrhage is suspected but CT is negative,
especially within the first 6-12 hours of symptom onset. It can detect xanthochromia or red blood cells in the
CSF.
3. A 65-year-old male with a history of COPD presents with severe respiratory distress. His oxygen saturation
is 83% on 2 L nasal cannula. An arterial blood gas shows pH 7.15, PaCO2 70 mmHg, and PaO2 45 mmHg.
Which of the following is the most appropriate next step in management?
A. Increase oxygen to 4 L via nasal cannula
B. Initiate non-invasive positive pressure ventilation (NIPPV)
C. Intubate and initiate mechanical ventilation
D. Administer IV corticosteroids
🟢 C. Intubate and initiate mechanical ventilation
🔴 RATIONALE: The patient has severe hypercapnic respiratory failure with pH < 7.25 and evidence of
, impending respiratory failure. Intubation is indicated due to the severity of respiratory distress and failure of
non-invasive measures.
4. A 36-year-old male presents with a gunshot wound to the right chest. He is hypotensive and has jugular
venous distension. Breath sounds are diminished on the right side. Which of the following is the most
appropriate initial intervention?
A. Needle decompression
B. Chest tube insertion
C. Pericardiocentesis
D. Thoracotomy
🟢 A. Needle decompression
🔴 RATIONALE: The patient has signs of tension pneumothorax (hypotension, JVD, diminished breath sounds).
Needle decompression is the immediate life-saving intervention, followed by chest tube insertion.
5. A 32-year-old female presents with a fever, chills, and flank pain. Her urinalysis shows WBC casts. Which of
the following is the most likely diagnosis?
A. Cystitis
B. Urethritis
