A nurse is caring for a client who is in the emergency department with multiple traumatic injuries following a motor-vehicle crash. Which of the following actions should the nurse take first?

Choice A reason: Warming blood products prevents hypothermia during transfusion but is not the priority in a trauma patient. Airway management takes precedence, as oxygenation is critical to survival. Administering blood products comes later in the trauma algorithm, after securing the airway and stabilizing breathing, making this action secondary. Choice B reason: Establishing a patent oral airway is the first priority in trauma care, following the ABCs (Airway, Breathing, Circulation). A clear airway ensures oxygenation, critical for preventing hypoxia in a patient with multiple injuries. Without a patent airway, other interventions are ineffective, as oxygen delivery is essential for survival and organ function. Choice C reason: Creating a sterile field for wound care is important to prevent infection but is not the first priority in a trauma patient. Airway and breathing take precedence, as immediate life-threatening issues like hypoxia or shock must be addressed before wound care, making this action lower in priority. Choice D reason: Administering IV fluids to maintain blood pressure is part of the circulation phase in trauma care but follows airway and breathing stabilization. Without a patent airway, fluid administration cannot address hypoxia, a primary cause of mortality in trauma. This action is secondary to ensuring airway patency.
