• INTRODUCTION *
The Certified Emergency Nurse (CEN) examination evaluates the knowledge, judgment, and clinical
decision-making skills required for safe and effective emergency nursing practice. The exam assesses
foundational concepts, emergency assessment techniques, prioritization, stabilization, and
management of patients across the lifespan. Questions include both knowledge-based and scenario-
based formats that reflect real-world emergency department situations. Candidates must
demonstrate proficiency in trauma care, cardiovascular emergencies, neurologic crises, respiratory
conditions, ethical responsibilities, and legal considerations. Success requires the ability to apply
evidence-based practice, think critically under pressure, and make timely decisions that promote
optimal patient outcomes.
SECTION ONE: QUESTIONS 1–20
1. Which triage principle is most important when multiple patients arrive simultaneously in the
emergency department?
A. Treat patients in order of arrival
B. Prioritize based on severity of illness or injury
C. Treat pediatric patients first
D. Prioritize patients requesting pain medication
Correct Answer: B. Prioritize based on severity of illness or injury
Explanation: Emergency triage prioritizes patients according to acuity and risk to life rather than
arrival time.
2. A patient presents with chest pain, diaphoresis, and nausea. What is the priority nursing action?
A. Obtain a detailed dietary history
B. Encourage oral fluids
,C. Obtain a 12-lead ECG immediately
D. Schedule outpatient cardiology follow-up
Correct Answer: C. Obtain a 12-lead ECG immediately
Explanation: Rapid ECG acquisition is critical for identifying acute coronary syndromes and
guiding urgent treatment.
3. Which rhythm is most commonly associated with sudden cardiac arrest requiring defibrillation?
A. Sinus bradycardia
B. Atrial flutter
C. Ventricular fibrillation
D. First-degree AV block
Correct Answer: C. Ventricular fibrillation
Explanation: Ventricular fibrillation is a shockable rhythm and a leading cause of sudden cardiac
arrest.
4. A trauma patient has absent breath sounds on the right side, hypotension, and tracheal
deviation. Which condition is most likely?
A. Pulmonary edema
B. Cardiac tamponade
C. Simple pneumothorax
D. Tension pneumothorax
Correct Answer: D. Tension pneumothorax
Explanation: Tension pneumothorax causes respiratory compromise and obstructive shock
requiring immediate decompression.
5. Which assessment finding is most concerning in a patient with head trauma?
A. Mild headache
B. Glasgow Coma Scale decrease from 15 to 12
C. Scalp abrasion
D. Temporary anxiety
Correct Answer: B. Glasgow Coma Scale decrease from 15 to 12
Explanation: A declining GCS may indicate worsening intracranial injury and requires urgent
evaluation.
6. A patient with suspected stroke arrives within one hour of symptom onset. What is the nursing
priority?
, A. Delay imaging until laboratory results return
B. Initiate stroke protocol immediately
C. Administer aspirin before evaluation
D. Encourage ambulation
Correct Answer: B. Initiate stroke protocol immediately
Explanation: Rapid stroke assessment and imaging improve eligibility for time-sensitive
interventions.
7. Which symptom is most characteristic of hypovolemic shock?
A. Warm flushed skin
B. Bounding pulse
C. Bradycardia
D. Tachycardia with hypotension
Correct Answer: D. Tachycardia with hypotension
Explanation: Compensatory tachycardia and reduced blood pressure commonly occur with
significant volume loss.
8. A patient with severe asthma develops a silent chest. What does this indicate?
A. Improvement in airflow
B. Mild bronchospasm
C. Impending respiratory failure
D. Anxiety-related symptoms
Correct Answer: C. Impending respiratory failure
Explanation: A silent chest suggests critically reduced airflow and is a life-threatening finding.
9. Which laboratory value is most important when monitoring a patient receiving heparin therapy?
A. Hemoglobin A1C
B. Activated partial thromboplastin time (aPTT)
C. Serum sodium
D. Creatinine kinase
Correct Answer: B. Activated partial thromboplastin time (aPTT)
Explanation: aPTT is commonly used to monitor therapeutic anticoagulation with heparin.
10. A burn patient has circumferential burns to both arms. What complication is the greatest
concern?
