The nurse in a trauma unit has received report on a client who has multiple injuries following a motor vehicle crash. Which of the following actions should the nurse plan to take first?

Choice A reason: Evaluating chest expansion assesses breathing, the second priority in the ABCDE approach. Trauma from a motor vehicle crash may cause rib fractures, pneumothorax, or hemothorax, impairing ventilation. Unequal or absent expansion indicates a life-threatening issue, requiring immediate intervention like chest tube placement to restore adequate respiration. Choice B reason: Assessing capillary refill evaluates peripheral perfusion, a circulation parameter in the ABCDE approach. While important, it is secondary to airway and breathing. Trauma patients may have shock, but chest injuries affecting ventilation (e.g., pneumothorax) are more immediate threats, making chest expansion the first assessment to ensure respiratory function. Choice C reason: Checking pupillary response assesses neurological status (disability in ABCDE), relevant for head trauma. However, breathing takes precedence over neurological assessment in trauma patients. Chest injuries can cause rapid respiratory failure, making chest expansion evaluation critical to identify life-threatening conditions like flail chest or pneumothorax before neurological checks. Choice D reason: Checking orientation to place and time assesses neurological function, part of the disability component in ABCDE. While important in trauma, it is secondary to airway and breathing. Chest injuries from a crash can compromise ventilation, making chest expansion the priority to detect and address immediate respiratory threats before neurological evaluation.
