CEN Flashcards prepare for the Certified Emergency Nurse Exam. A certified emergency nurse commonly treats patients while they face a life-threatening crisis. They are most likely to be involved while an illness or injury is still in a critical stage. In order to be eligible to take the Certified Emergency Nurse Exam, one must have a current, unrestricted nursing license or nursing certificate that is equivalent to a Registered Nurse in the United States. It is also recommended, though not required, to have at least two years of experience as an emergency room nurse in the United States. The Certified Emergency Nurse exam is a computer-based examination. It consists of 175 multiple choice questions. 150 of these CEN test items are scored, and 25 items are pretest items. The pretest items are not scored. There is a maximum of three hours in which to complete the entire CEN examination. Thirteen subject areas are covered on the CEN examination, and they are as follows: Cardiovascular Emergencies (17 items), Gastrointestinal Emergencies (9 items), Obstetrical, Genitourinary, and Gynecological Emergencies (10 items), Maxillofacial and Ocular Emergencies (9 items), Neurological Emergencies (12 items), Orthopedic Emergencies and Wound Management (15 items), Psycho/Social (7 items), Respiratory Emergencies (18 items), Patient Care Management (12 items), Substance Abuse/Toxicological and Environmental Emergencies (13 items), Shock/Multi-System Trauma Emergencies (8 items), Medical Emergencies/Communicable Diseases (13 items), and Professional Issues (7 items).
