A nurse is conducting a primary assessment of a 35-year-old patient who arrives at the emergency department via ambulance following a high-speed motor vehicle collision. The patient is conscious but appears anxious and is complaining of chest pain. Which assessment should the nurse prioritize first?

Primary Assessment in Trauma: The ABCDE Framework

The initial approach to any trauma patient follows a systematic, prioritized sequence known as the primary survey. This sequence is universally taught in trauma nursing core courses and is a foundational concept for the NCLEX-RN. The goal is to identify and manage the most immediate life-threatening conditions first. The established order is A (Airway with cervical spine protection), B (Breathing), C (Circulation), D (Disability/Neurological status), and E (Exposure/Environmental control).

The Guidelines for Essential Trauma Care emphasize that strengthening the organization of trauma care, which includes the systematic clinical assessment of injured patients, is fundamental to lowering mortality ^[1]. This structured approach ensures that physiological threats are addressed in order of lethality. A compromised airway or ineffective breathing will lead to death within minutes, preceding the consequences of circulatory collapse or neurological deterioration. Therefore, in a conscious patient complaining of chest pain after a high-speed collision, the nurse's immediate priority is to ensure that the airway is patent and that ventilation is adequate. Chest pain in this context could indicate a life-threatening injury such as a tension pneumothorax, massive hemothorax, or flail chest, all of which directly impair breathing and oxygenation.

While assessing for internal bleeding (option 1) and evaluating neurological status (option 3) are critical components of the primary survey, they fall under "C" (Circulation) and "D" (Disability), respectively. These steps are performed only after the airway and breathing have been assessed and stabilized. Examining for fractures and external injuries (option 4) is part of the secondary survey, which occurs after the primary survey is complete and the patient's immediate life threats have been addressed. The correct clinical decision-making process is to follow the A-B-C-D-E sequence without deviation, as this standardization is a core principle promoted by international trauma care guidelines to improve patient outcomes ^[1].
