CERTIFIED EMERGENCY NURSE
(CEN) COMPREHENSIVE
CERTIFICATION EXAMINATION
100 CERTIFICATION-LEVEL
PRACTICE QUESTIONS WITH
DETAILED RATIONALES
DOCUMENT DESCRIPTION
The Certified Emergency Nurse (CEN) Comprehensive Certification Examination is
designed to prepare registered nurses for specialty certification in emergency nursing
practice. This examination reflects the knowledge, clinical judgment, critical thinking, and
rapid decision-making skills required in emergency departments, trauma centers, urgent care
settings, and disaster response environments.
Content areas covered throughout this examination include:
• Triage and Prioritization
• Emergency Assessment
• Trauma Nursing
• Cardiovascular Emergencies
• Respiratory Emergencies
• Neurological Emergencies
• Shock and Hemodynamic Instability
,• Toxicology and Poisoning
• Environmental Emergencies
• Gastrointestinal Emergencies
• Endocrine Emergencies
• Infectious Disease Emergencies
• Orthopedic Emergencies
• Psychiatric and Behavioral Emergencies
• Pediatric Emergencies
• Obstetric Emergencies
• Disaster Preparedness
• Emergency Pharmacology
• Ethical and Legal Issues
• Evidence-Based Emergency Care
This examination is designed to strengthen clinical judgment, prioritization skills, emergency
interventions, patient safety, and professional emergency nursing competencies commonly
assessed on the CEN certification examination.
PRACTICE QUESTIONS
Question One
A triage nurse is assessing four patients arriving simultaneously in the emergency
department. Which patient should be prioritized first?
,A. A patient with chest pain and diaphoresis
B. A patient with a sprained ankle
C. A patient requesting a prescription refill
D. A patient with a minor laceration
Correct Answer: A. A patient with chest pain and diaphoresis
Rationale: Chest pain accompanied by diaphoresis may indicate acute coronary syndrome
or myocardial infarction. Rapid assessment and intervention are essential because delays
can result in significant morbidity and mortality. Airway, breathing, circulation, and life-
threatening conditions always take priority during triage.
Question Two
A patient presents with signs of tension pneumothorax. Which assessment finding is most
concerning?
A. Tracheal deviation and severe respiratory distress
B. Mild cough
C. Low-grade fever
D. Nasal congestion
Correct Answer: A. Tracheal deviation and severe respiratory distress
Rationale: Tension pneumothorax is a life-threatening emergency characterized by
increasing intrathoracic pressure, impaired venous return, severe respiratory compromise,
and possible cardiovascular collapse. Immediate decompression is required.
Question Three
A nurse is caring for a trauma patient with suspected hemorrhagic shock. Which finding is
expected?
A. Tachycardia and hypotension
B. Bradycardia and hypertension
C. Warm dry skin and hypertension
, D. Decreased respiratory rate
Correct Answer: A. Tachycardia and hypotension
Rationale: Hemorrhagic shock results from significant blood loss. Compensatory
mechanisms initially produce tachycardia and vasoconstriction, followed by hypotension as
volume loss worsens.
Question Four
A patient experiencing an acute ischemic stroke arrives within the treatment window. What is
the priority nursing action?
A. Rapid stroke assessment and activation of stroke protocol
B. Delay evaluation until symptoms stabilize
C. Administer oral fluids immediately
D. Encourage ambulation
Correct Answer: A. Rapid stroke assessment and activation of stroke
protocol
Rationale: Time-sensitive interventions significantly improve neurological outcomes in
ischemic stroke. Emergency nurses play a critical role in rapid recognition and protocol
activation.
Question Five
A patient arrives with severe wheezing and difficulty speaking. Which finding suggests a life-
threatening asthma exacerbation?
A. Inability to speak full sentences
B. Mild cough
C. Normal oxygen saturation
D. Occasional throat clearing
Correct Answer: A. Inability to speak full sentences
