Introduction
This structured NR511 CEA EXAM format for 2026–2027 provides the complete layout for generating high-quality exam-style questions with correct answers and rationales.
It emphasizes foundational advanced nursing principles, clinical diagnostic reasoning, patient safety protocols, and evidence-based primary care strategies critical to
professional nurse practitioner practice and successful academic certification.
The official, verified question count for the actual NR511 CEA (Comprehensive Clinical Exam / Differential Diagnosis and Primary Care Practicum) Examination is exactly 150
multiple-choice questions. This document mirrors that authentic exam length and structure.
Answer Format
All correct answers appear in BOLD CYAN. Each question includes a concise rationale explaining safety/clinical reasoning, protocol adherence, and why alternative options
are less appropriate.
1. A 45-year-old smoker presents with a productive cough for 3 weeks, low-grade fever, and night sweats. Chest X-ray shows upper
lobe infiltrates. The most likely diagnosis is:
A. Lung cancer
B. Acute bronchitis
C. Pulmonary tuberculosis
D. Community-acquired pneumonia
Correct Answer: C. Pulmonary tuberculosis
Rationale: Classic presentation of pulmonary TB includes chronic cough, night sweats, weight loss, and upper lobe infiltrates on CXR, especially in
smokers or those with risk factors.
2. A 28-year-old with sudden-onset pleuritic chest pain and dyspnea after a long flight has O2 sat 92%. The priority diagnostic test is:
A. D-dimer
B. CT pulmonary angiogram
C. Chest X-ray
D. EKG
Correct Answer: B. CT pulmonary angiogram
Rationale: High clinical suspicion for PE (recent travel, pleuritic pain, hypoxia) warrants immediate CT pulmonary angiogram for definitive diagnosis.
3. Which finding distinguishes asthma from COPD?
A. Reversible airway obstruction
B. Barrel chest
C. Chronic productive cough
, D. Smoking history
Correct Answer: A. Reversible airway obstruction
Rationale: Asthma is characterized by reversible bronchospasm and airway hyperresponsiveness, unlike the largely irreversible obstruction in COPD.
4. A patient with suspected community-acquired pneumonia has a CURB-65 score of 3. Management includes:
A. Observation only
B. Outpatient oral antibiotics
C. Hospital admission and IV antibiotics
D. Home oxygen only
Correct Answer: C. Hospital admission and IV antibiotics
Rationale: CURB-65 score ≥3 indicates severe pneumonia requiring hospitalization and IV antibiotics.
5. A 60-year-old with chronic cough, hemoptysis, and weight loss has a cavitary lesion on CXR. Differential includes:
A. Lung cancer or tuberculosis
B. Allergic rhinitis
C. GERD
D. Viral bronchitis
Correct Answer: A. Lung cancer or tuberculosis
Rationale: Cavitary lesions with constitutional symptoms raise concern for malignancy or TB; further workup with CT and sputum studies is
warranted.
6. Which is the first-line treatment for uncomplicated acute bacterial sinusitis in adults?
A. No antibiotics initially
B. Amoxicillin-clavulanate
C. Ciprofloxacin
D. Azithromycin
Correct Answer: B. Amoxicillin-clavulanate
Rationale: Amoxicillin-clavulanate is recommended first-line for acute bacterial sinusitis due to coverage of resistant organisms.
7. A patient with COPD exacerbation has increased dyspnea, purulent sputum, and wheezing. Initial management includes:
A. Chest physiotherapy only
B. Immediate intubation
C. Only antibiotics
D. Systemic corticosteroids and bronchodilators
Correct Answer: D. Systemic corticosteroids and bronchodilators
Rationale: Standard treatment for COPD exacerbation includes bronchodilators, systemic steroids, and antibiotics if infection is suspected.
8. Which symptom is most specific for pertussis in adults?
A. Fever >102°F
B. Chest pain
C. Paroxysmal cough followed by whoop or post-tussive vomiting
, D. Productive cough
Correct Answer: C. Paroxysmal cough followed by whoop or post-tussive vomiting
Rationale: Paroxysmal cough with whoop or post-tussive emesis is highly suggestive of pertussis, even in adults with waning immunity.
9. A 35-year-old with acute dyspnea, wheezing, and O2 sat 88% after bee sting has:
A. Anaphylaxis with bronchospasm
B. Pneumothorax
C. Asthma exacerbation
D. Pulmonary embolism
Correct Answer: A. Anaphylaxis with bronchospasm
Rationale: Sudden onset after allergen exposure with hypoxia and wheezing indicates anaphylaxis requiring immediate epinephrine.
10. Which test confirms the diagnosis of active pulmonary tuberculosis?
A. Sputum acid-fast bacilli smear and culture
B. PPD skin test
C. Chest CT
D. Interferon-gamma release assay
Correct Answer: A. Sputum acid-fast bacilli smear and culture
Rationale: Definitive diagnosis of active TB requires microbiologic confirmation via sputum AFB smear and culture (or NAAT).
11. A patient with suspected influenza presents within 36 hours of symptom onset. Best management is:
A. Chest X-ray immediately
B. Supportive care only
C. Oseltamivir within 48 hours of symptom onset
D. Amoxicillin
Correct Answer: C. Oseltamivir within 48 hours of symptom onset
Rationale: Neuraminidase inhibitors like oseltamivir are most effective when started within 48 hours of influenza symptom onset.
12. Which physical finding is most consistent with a large pleural effusion?
A. Tracheal deviation away from the affected side
B. Wheezes throughout
C. Hyperresonance to percussion
D. Dullness to percussion with decreased breath sounds
Correct Answer: D. Dullness to percussion with decreased breath sounds
Rationale: Pleural effusions cause dullness to percussion and diminished breath sounds over the affected area.
13. A 22-year-old with recurrent sinusitis, nasal polyps, and asthma likely has:
A. Immunodeficiency
B. Cystic fibrosis
C. Allergic rhinitis
, D. Aspirin-exacerbated respiratory disease (Samter’s triad)
Correct Answer: D. Aspirin-exacerbated respiratory disease (Samter’s triad)
Rationale: The triad of asthma, nasal polyps, and aspirin sensitivity defines aspirin-exacerbated respiratory disease.
14. A patient with community-acquired pneumonia fails to improve after 72 hours of antibiotics. Next step:
A. Obtain chest CT and consider atypical pathogens or complications
B. Switch to oral antibiotics only
C. Continue current antibiotics
D. Discharge home
Correct Answer: A. Obtain chest CT and consider atypical pathogens or complications
Rationale: Lack of clinical improvement at 48-72 hours warrants imaging and consideration of resistant organisms, complications, or alternative
diagnoses.
15. Which vaccine is recommended annually for all adults to prevent respiratory illness?
A. Tdap
B. Influenza
C. Hepatitis B
D. Pneumococcal
Correct Answer: B. Influenza
Rationale: Annual influenza vaccination is recommended for all adults to reduce morbidity and mortality from seasonal flu.
16. A 68-year-old with COPD has an FEV1 of 45% predicted. This indicates:
A. Moderate to severe COPD
B. Restrictive disease
C. Normal lung function
D. Mild COPD
Correct Answer: A. Moderate to severe COPD
Rationale: FEV1 30-49% predicted indicates severe COPD (GOLD stage 3); 50-79% is moderate.
17. A patient with acute bronchitis requests antibiotics. The best response is:
A. Order chest X-ray first
B. Prescribe azithromycin for 5 days
C. Explain that most cases are viral and antibiotics are not indicated
D. Prescribe amoxicillin-clavulanate
Correct Answer: C. Explain that most cases are viral and antibiotics are not indicated
Rationale: Acute bronchitis is predominantly viral; antibiotics are not recommended unless bacterial superinfection is suspected.
18. Which finding on physical exam suggests pneumothorax?
A. Dullness to percussion
B. Bilateral crackles
C. Hyperresonance and decreased breath sounds on one side
